Anionic and cationic surfactants examples

Surfactants come in four different types: Anionic, nonionic, cationic and amphoteric. Once you understand the differences between these different surfactant types, as well as how to classify them by their names, choosing the right cleaning products should be a snap List of anionic, cationic and non-ionic surfactants. A discussion started in 2001 but continuing through 2018. 2001. Q. Could you give me a list of anionic, cationic and non-ionic surfactants. The chemical names as well as the Analysis method if possible. Thanks, Mrs. Anjali Koparka Surfactants are categorized by the 'chemical charge' of their water-soluble end: 1. Ionic (surfactants that have a charge) An ionic surfactant is one that has an electric charge. There are three types of ionic surfactant: Anionic (negatively charged) Cationic (positive charge) Amphoteric (contains a positive and negative charge

Examples of anionic surfactant groups include sulfonic acid salts, alcohol sulfates, alkylbenzene sulfonates, phosphoric acid esters, and carboxylic acid salts. Many anionic surfactants can also act as hydrotropes, which serve to raise the cloud point of nonionic surfactants cationic. surfactants the charge is carried on a nitrogen atom as, for example, with amine and quaternary ammonium surfactants. The quaternary ammonium compounds retain this charge over the whole pH range, whereas the amine-based compounds only function as surfactants in the protonated state and therefore cannot be used at high pH Precipitation of anionic surfactants [3-5] and mixtures of anionic/nonionic surfactants has been previously successfully modeled, and the behavior and physicochemical properties of mixtures of a highly branched cationic and sodium alkyl sulfate have been widely studied by Zhi-Jian Yu and co-workers [7-9] An anionic surfactant is a type of surfactant that has or carries a negative charge on its hydrophilic end. When these surfactants are mixed with water, negatively charged anions, are created. One of the distinguishing features is its uncanny ability to attach to a positively charged particle which could be oils or dirt

Perhaps, the most commonly understood interaction between surfactants are anionic and cationic interactions. A dilute aqueous solution of stearalkonium chloride mixed with sodium lauryl sulfate a. The key difference between anionic cationic and nonionic surfactants is that anionic surfactants contain negatively charged functional groups, and cationic surfactants contain positively charged functional groups, whereas nonionic surfactants have no net electrical charge.. The term surfactant refers to surface-active agents. That means, the surfactants can reduce the surface tension between. Anionic surfactants are electrolytes, and a surface-active ion is an anion when the surfactants dissociate in water. The anionic surfactants adsorb on various kinds of substrates and give them an anionic charge. This action of the anionic surfactant contributes to the strong detergency and high foaming power of the agent KEY WORDS: Alumina, anionic surfactant, cationic surfactant, mixed surfactant, precipitation, silica. Mixtures of anionic and cationic surfactants act synergisti-cally, as evidenced by ultralow critical micelle concentrations (CMC), increased surface activity (1,2) and improved deter-gency performance (3). The main disadvantage of mixed an The author describes how the anionic/cationic interaction is critical to properties such as foam, viscosity, conditioning properties and minimal irritation. acids bind strongly to hard bases and soft acids bind softly to soft bases;1 the anionic and cationic interactions of surfactants are exactly analogous

Commercial surfactants are commonly a mixture of cationic, anionic and non-ionic surfactants due to their enhanced performance as mixtures. 1, 2 Therefore, along the studies of non-ionic and ionic. Typical examples are trimethylalkylammonium chlorides, and the chlorides or bromides of benzalkonium and alkylpyridinium ions. All are examples of quats, so named because they all contain a quaternary ammonium ion. Cationic surfactants make lipophilic substances dissolve in water molecules The structure of anionic surfactant is shown in (Figure 2) [30]. Figure 2: Linear alkyl sulphate (Anionic surfactant) Cationic surfactants: Cationic surfactants are liquefied in water producing positive ions of the surface-active group. They possess great superficial action in an acidic medium and are expected to show swift and drop action in. Josef Steber, in Handbook for Cleaning/Decontamination of Surfaces, 2007. 3.1.3. Cationic Surfactants. Cationic surfactants are not contained in usual cleaning products but are the active agents in fabric softeners which represent an important group of detergent products.. Until the beginning of 1990s, di-tallow dimethyl ammonium chloride (DTDMAC) had represented the most important cationic.

Surfactants and anionic, nonionic and cationic properties

  1. The cationic latex may be converted into a stable anionic latex by adding a nonionic surfactant, if such surfactant is not added prior to the polymerization of monomers, to stabilize the latex during subsequent pH adjustment to a pH greater than 8, and usually from pH 9 to pH 10, preferably by the addition of ammonium hydroxide
  2. Zwitterionic or amphoteric surfactants have both cationic and anionic centers attached to the same molecule. Two major surfactants, are linear alkylbenzene sulfonates (LAS) and the alkyl phenol ethoxylates (APE). anionic surfactants contain anionic functional groups at their head, such as sulfate, sulfonate, phosphate, and carboxylates
  3. Polyquarternium-10 is one of the most common cationic conditioners. It is based on a cellulose polymer that is then quarternerised to give the desired properties. The major problem of the 2-in-1 products is the inclusion of anionic and cationic surfactants in the same formulation
  4. Many common cationic surfactants are irritating to the skin so limit the use to just what is ncessary. Cleansers containing cationic surfactants cannot be mixed with those containing oppositely charged anionic surfactants. The molecules would interact with each other, producing a gooey mess that drops out of solution
  5. Cetyl- pyridinium chloride (CPC) and sodium dodecyl sulfate (SDS) are chosen as typical cationic and anionic surfactants, respectively. It is found that the cationic CPC exhibits negligible adsorption on synthetic cal- cite in deionized water compared with the adsorption of the anionic SDS
  6. es or quaternary ammonium cations. The anionic part can be more variable and include sulfonates, as in the sultaines CHAPS (3-[(3-cholamidopropyl)dimethylammonio]-1-propanesulfonate.
  7. There are 4 types of surfactants based on their interfaces and charges: nonionic, anionic, cationic, amphoteric. A nonionic surfactant has no charge groups in its head. If the charge is negative, the surfactant is more specifically called anionic

An Anionic emulsion has a negative charge, a Cationic emulsion has a positive charge, and a Non-ionic emulsion has no charge. Most of the things in the world are Anionic and that is why the majority of Research and Development, formulating, and lab testing has been done in the Industrial Coatings Industry to make coatings from Anionic systems Mixtures of surfactants can exhibit synergistic gains compared to the parent surfactants in both surface and bulk properties.4-10 This is particularly true when there are attractive interactions between the surfactants, as is the case in mixtures of anionic and cationic surfactants. For example, adding small amounts of the anionic 7. Uniquat(R) 2250 is an effective cationic surfactant that can be used in a variety of cleaning systems. 8. Uniquat(R) 2280 is an effective cationic surfactant that can be used in a variety of cleaning systems. 9. Didecyl Dimethyl Ammonium Chloride is a compound that exhibits some fungacidal and antimirobial functions Understanding the interactions of surfactants is important to optimizing their properties in formulations. The author describes how the anionic/cationic interaction is critical to properties such as foam, viscosity, conditioning properties and minimal irritation

The invention is directed to a surfactant composition, uses thereof and a method for making the same. The surfactant composition comprises at least two anionic surfactants and at least one cationic surfactant. The surfactant composition is useful, for example, in cleaning products and/or personal care products Types of Surfactants. There are four types of surfactants: anionic, cationic, amphoteric, and non-ionic. According to this study, the order of surfactant potential for SC [stratum corneum] alteration and skin irritation is cationic=anionic>amphoteric>nonionic Zwitterionic surfactants have both cationic and anionic centers attached to the same molecule. The cationic part is based on primary, secondary, or tertiary amines or quaternary ammonium cations. The anionic part can be more variable and include sulfonates, as in the sultaines CHAPS (3-[(3-cholamidopropyl)dimethylammonio]-1-propanesulfonate. Surfactants can be grouped by the charge characteristic of their polar (hydrophilic) head groups. The four groups include. Anionic Cationic Amphoteric Non-Ionic. We'll discuss each of these next. Anionic Surfactants. Anionic surfactants are those that have a negative charge on their polar head group Cationic surfactants are good in formulations for co-wash and 2-in-1 conditioning shampoo. Cationic surfactants do not combine well with anionic surfactants. Amphoteric Surfactants Amphoteric surfactants can have a negative or positive charge or no charge depending on the acid or alkaline environment. Amphoteric surfactants are generally used.

List of anionic, cationic and non-ionic surfactant

  1. surfactants and their mixtures. Anionic surfactant sodium dodecyl sulfate (SDS) and cationic surfactant cetyltrimethylammonium bromide (CTAB) are chosen as characteristic examples. Coarse-grained models of the surfactants are constructed and parameterized using a combination of atomistic molecular simulation and infinite dilution activity.
  2. Non-ionic surfactants do not ionize the cleaning solution, giving them no electrical charge, a feature that resists water hardness and cleans the widest variety of soils. Other classifications include anionic, which carries a negative charge; a cationic or positive charge; and amphoteric, which carries a positive, negative or neutral charge.

  6. Anionic surfactants. A classic example of an anionic surfactant used in the cosmetic industry is Sodium Lauryl Sulfate. The surfactant portion of the molecule is Lauryl Sulfate which has a negative charge. In this surfactant, the Lauryl part is the nonpolar end while the Sulfate is the polar end
  7. anionic and nonionic surfactants is used, the detergent is referred to as being anionic. Use of the term nonionic, however, does not necessarily mean that the detergent is ion-free. For example, Alcojet is a nonionic detergent, but most of its other ingredients are sodium salts. As a result, Alcojet is a nonionic, highly ionic detergent

The competition between lysozyme and cationic amphiphiles as hosts for the anionic surfactants was studied experimentally and analyzed quantitatively. Aggregates with C12 cationic surfactants are clearly preferred by the anionic surfactants, while for C10 and particularly C8 a clear excess of cationic surfactant has to be added to completely.

Ionic surfactants are the most toxic if they are soluble in water. Crystalline ionic surfactants of low solubility show low toxicity. The sign of the charge, anionic or cationic, does not matter. On the other hand, for sucrose ester surfactants, C12 alkyl length resulted in the greatest skin toxicity Japanese publication No. JP81055497 teaches that a cationic and anionic surfactant liquid detergent composition may be stable in the absence of additives such as propylene glycol and sodium benzene sulfonate and sodium p-toluene sulfonate. The Example shows 20 wt.% total of anionic surfactant and 2.7 wt. % of cationic surfactant There are some cationic surfactants mixed with anionic / cationic surfactants that are soluble (visually clear combinations), even at stiochiometric concentrations (2). This observation allows for classifi cation of two types of quats, one hard and the other soft. Hard quats were those products which were incompatible with anionic surfactants inorganic species with a cationic surfactant (S+I'), the syntheses of MCM-41 and MCM-48 (1-3) are prototypic examples. A similar route to periodic tubular non silica structures, but involving cooperative condensation of a cationic inorganic species with an anionic surfactant (S'I+) is demonstrated for the first time

For instance, an anionic surfactant is an effective foam booster but it will tend to irritate skin. To counteract this an amphoteric surfactant is needed. To increase the conditioning property of a shampoo, a cationic surfactant is added Key words: Surfactant, Cationic, Anionic,Petroleum . I. INTRODUCTION Surfactant can be define as 'surface active agents' or an organic compound having at least one lyophilic ('solvent-loving') group and one lyophobic ('solvent-fearing') group in the molecule. surfactants can be used in variou anionic surfactants, cationic surfactants and amphoteric surfactant. Special features or new type surfactant is as special surfactant [4,5]. Anionic surfactants The anionic surfactantsare dissolved in water with generating the negatively charged surface active group, whoseaqueous solution is neutral or alkaline[6]

Difference Between Anionic Cationic and Nonionic Surfactant

To date, only limited studies have been conducted on use of mixtures of anionic and cationic surfactants for EOR, by Anton [1], Wellington [14], Gogoi [15] and Doan [16]. In our previous study [17, 18], binary mixtures of anionic/cationic surfactants were investigated and found to have great potential for enhanced oil recovery Anionic Anionic surfactants, the most common of which are the alkyl sulfates, are really the primary ingredient used in cleansing products. They are positively charged surfactant ions. Examples include sodium lauryl sulfate and ammonium lauryl sulfate (ALS). Sometimes anionic surfactants are modified to make them less irritating

In other words, cationic surfactants are titrated with anionic surfactants and vice versa. This means that a cationic compound, such as quaternary ammonium salt, is titrated potentiometrically in an aqueous medium with a standard solution of sodium lauryl sulfate (SLS), an anionic surfactant A surfactant is a compound that lowers the surface tension between two dissimilar phases (e.g. a liquid solvent and a solid, or two liquids like water and oil - typical example) and thus permits their mixing. They all consist of two different part..

What are anionic detergents give an example

Surfactants adsorb preferably at interfaces where they find the energetically most favourable conditions due to their two-part structure. At a water surface, for example, the surfactants orient themselves in such a way that the head group resides in the water and the hydrocarbon chain points to the gaseous phase (see figure 2).Thus surfactants can mediate between two phases as they can form. Some cationic surfactants are used as emulsifiers and are great for hair conditioners. (I use BTMS, a cationic surfactant, in my hair conditioner recipe.) These are classified based on the charge of the polar head of the surfactant which can have a positive charge (cationic), a negative charge (anionic), or no charge (non-inonic) Cationic and anionic surfactants are generally limited to use in topical, o/w emulsions. Cationic agents (quarternary ammonium salts) are incompatible with organic anions and are infrequently used as emulsifiers. Soaps are subject to hydrolysis and may be less desirable than the more stable detergents

Currently, the global surfactant market has been segmented into anionic, cationic, non-ionic and amphoteric [ 31 ]. Anionic surfactants, like alkylbenzene sulfonates, α-olefin sulfonates, sulphates and ether sulphates, carboxylates, isethionates, taurates and phosphate surfactants held around 50% share of the global surfactant market inorganic species with a cationic surfactant (S+I'), the syntheses of MCM-41 and MCM-48 (1-3) are prototypic examples. A similar route to periodic tubular non silica structures, but involving cooperative condensation of a cationic inorganic species with an anionic surfactant (S'I+) is demonstrated for the first time For research or industrial application, a specific anionic or cationic surfactant to be used should be selected for the surfactant calibration. For the water quality control of unknown samples, the most common anionic surfactant, linear alkylate sulfonate, and the most common cationic surfactant, quaternary ammonium chloride, are selected as. Zwitterionic surfactants have both anionic and cationic centers attached to the same molecule. The cationic part is based on primary, secondary, or tertiary amines or quaternary ammonium cations. The anionic part can be more variable and often includes sulfonates. An example of a zwitterionic surfactant used in many food an CO 2-responsive switchable surfactants that can be switched on and off by CO 2 addition and removal would allow facile emulsion breaking, but all reported examples are cationic surfactants. Because soil washing requires anionic surfactants, we have investigated phenolate, benzoate and carboxylate salts as switchable anionic surfactants

Surface Active Agents (Surfactants): Types and Application

Anionic surfactants dissociate in aqueous solutions into a amphiphilic organic anion (negatively charged ion) and a small inorganic cation (positively charged ion: Na +, K +). Anionic surfacants are manufactured in the reaction of an organic substance with sodium/potassium hydroxide. Examples of anionic surfactants: linear alkylbenzene sulfonates, di-alkyl sulfosuccinate (sulfonic acid salt. 3. Cationic surfactants Cationic surfactants are the opposite of anionic surfactants. They have a positively charged water-loving head. This positive charge enables cationic surfactants to deliver nourishing benefits to skin, hair, and body, but used alone, do not have high foaming capabilities The effect of cationic micelles on solubilization of anionic azo dye in aqueous micellar solutions of cationic surfactants was studied at pH 7 and 25 â-¦C. The binding of dye to micelles implied a bathochromic shift in dye absorption spectra that indicates dye-surfactant interaction These surfactant molecules exhibit both anionic and cationic dissociations. Some examples of this class of surfactants are synthetic products like betaines or sulfobetaines and natural substances such as aminoacids and phospholipids [6 - 7]

Hey I ask about definition of amino basic surfactant and an example of it. mohamed saleh nasr science banha uni - zefta garbya egypt. September 8, 2018 Surfactants: Surfactants are compounds that lower the surface tension. They are preferentially adsorbed at the interfaces between two liquids, between a gas and a liquid, or between a liquid and a solid. Surfactants may act as detergents, wetting agents, emulsifiers, foaming agents, and dispersants. Cationic Surfactants varying amount of surfactants are consistent with sequential equilibrium involving surfactant monomers, micelles, dye aggregates, premicellar dye-surfactant complex and dye incorporated into the micelle.19,20 This paper presents a potentiometric study of the interactions between three anionic azo dyes, i.e., C.I Cationic part possess a long hydrocarbon chain and a positive charge on nitrogen atom.

What are Cationic Surfactants? (with pictures

surfactant mixtures has drawn the attention of academy and industry due to the general enhanced adsorption properties the mixtures present, as compared to the individual surfactants. These effects are especially enhanced in mixtures of cationic and anionic surfactants due to the electrostatic interaction between opposite charges that leads t For example, anionic surfactants with cleaning effect are used in the pretreatment process, and anionic surfactants with percolation effect are used in the dyeing and finishing processes. In addition, some functional products such as leveling agents and fixing agents are also anionic type Surfactants and detergents are an integral part of our daily life and play an important role in industry processes. The analysis of anionic, cationic or non-ionic surfactant concentration in formulations, raw products, liquid detergents, cosmetic products, lubricants, cooling emulsions etc. is an important quality criterion in production

Surfactants and their role in Pharmaceutical Product

For instance, negatively charged anionic surfactants are avoided in carbonate reservoirs whereas positively charged cationic surfactants are avoided in sandstone because of adsorption challenges. The oilfield chemistry (OFC) group at CPG is working on the molecular design of surfactants based on advanced structure-property relationships to. Furthermore, cationic surfactants are neutralized, chemically and functionally, by an equivalent amount of anionic sur­ factant so that they do not exist in free form i~ the presence of excess anionic. Anionic a~d nonionic surfactants are relatively non-toxic to mammals, falling in the· same general range as sodiu Surfactants lower the surface tension of an aqueous solution and are used as wetting agents, detergents, emulsifiers, antiseptics, and disinfectants. As antimicrobials, they alter the energy relationship at interfaces. Based on the position of the hydrophobic moiety in the molecule, surfactants are classified as anionic or cationic lammonium chloride (PDMDAAC) and the modified fly ash removed anionic dye by electrostatic interaction [8].Mohd Yusof removed the Cr(VI) and As(V) using the cationic surfactant-modified zeolite [9]. Because activated carbon (AC) has been implemented in most water and wastewater treatment processes, modification of AC and its application to the removal of ionic pollutants has been. For example, geramine is a cationic surfactant with good bactericidal effect. But the bactericidal function is obvious only when the concentration of surfactant reaches a certain critical value. Generally speaking, the toxicity of cationic surfactants is greater than that of nonionic surfactants, and the toxicity and bactericidal power of.

The CMC values of zwitterionic surfactants with linear carbon chains are between nonionic and anionic/cationic surfactants[32]. Some of the zwitterionic surfactants which reported in literature about polymerization are as follows: containing some n-alkyl dimethyl betaine (C x DMB, X=12,14,16), n-dodecyl amido propyl betaine, n-dodecyl dimethyl. Non-ionic, anionic and cationic surfactants are the most commonly used classes (Ying 2006). Examples of surfactants from these three classes are presented in Table 1.

surfactant and can alter the self-assembly in solution, leading to the formation of vesicles. For example, when alkyl sulfates (C nSO 4 -Naþ) with n greater than six are added to alkyl ammonium halide surfactants, vesicles can form on both the cationic and anionic-rich side of the phase diagram [6]. Suc The cationic surfactant did not affect strongly the surface charge of TiO 2 and therefore its zeta potential. On the other hand, the anionic surfactant (negative charged molecules) produced a decrease in the zeta potential values due to electrostatic interaction and partial neutralization of the charge at the TiO 2 surface A review of studies on adsorption of single surfactant as well as mixtures of various types (anionic-cationic, anionic-nonionic, cationic-nonionic, cationic-zwitterionic and nonionic-nonionic) is presented here along with mechanisms involved
