A discussion started in but continuing through Q. Could you give me a list of anionic, cationic and non-ionic surfactants. The chemical names. Once you understand the four different surfactant types differences choosing the right cleaning products should be a snap. Surfactants are one of many different compounds that make up a detergent. .. These products are formulated using cationic surfactants (sometimes combined.

In pharmacy[ edit ] A wetting agent is a surfactant that, when dissolved in water, lowers the advancing contact angle, aids in displacing an air phase at the surface, and replaces it with a liquid phase.

Examples of application of wetting to pharmacy and medicine include the displacement of air from the surface of sulfur, charcoal, and other powders for the purpose of dispersing these drugs in liquid vehicles; the displacement of air from the matrix of cotton pads and bandages so that medicinal solutions can be absorbed for application to various body areas; the displacement of dirt and debris by the use of detergents in the washing of wounds; and the application of medicinal lotions and sprays to cationic surfactants of skin and mucous membranes.

Pulmonary surfactant is produced in lungs in order to facilitate breathing by increasing total lung capacity, TLC, and lung compliance.

Surfactants

In respiratory distress syndrome or RDS surfactant replacement therapy helps patients have normal respiration by using pharmaceutical forms of the surfactants. One of the most important pharmaceutical pulmonary surfactants is Survanta beractant or its generic form Beraksurf produced by Abbvie and Tekzima respectively.

Current market and forecast[ edit ] The annual global production of surfactants was 13 million tonnes in cationic surfactants Market researchers expect annual revenues to increase by 2.

The commercially most significant type of surfactants is currently the anionic surfactant alkyl benzene sulfonate LASwhich is widely used in cleaners and detergents. Some of them are known to be toxic to animals, ecosystems, and humans, and can increase the cationic surfactants of other environmental contaminants.

Environmental Protection Agency and eight chemical companies to reduce and eliminate emissions of the chemical and its precursors.

Surfactant - Wikipedia

The long-chain alcohol can come from either a synthetic or natural source. Although they do not contain an ionic group as their hydrophilic component, hydrophilic properties are conferred on them by the presence of a number of oxygen atoms in one part of the molecule cationic surfactants are capable of forming hydrogen bonds with molecules of water.

As the temperature of cationic surfactants surfactant solution is increased the hydrogen bonds gradually break causing the surfactant to come out of solution.

This is commonly referred to as the cloud point and cationic surfactants characteristic for each nonionic surfactant. Nonionics are more surface active and better emulsifiers than anionics at similar concentrations.

They are less soluble than anionics in hot water and produce less foam. They are also cationic surfactants efficient in removing oily and organic dirt than anionics.

Depending on the type of fibre, they can be active in cold solution and so are useful in countries which lack hot water supplies and in developed countries where there is a desire to lower the wash temperatures either to save energy or because of the type of fabric being cationic surfactants.

Nonionics are used in fabric washing detergents both powders and liquidsin hard surface cleaners and in many industrial processes such as emulsion polymerization and agrochemical formulations.

Amphoteric surfactants Amphoteric or zwitterionic surfactants are so called because the head-group carries both a negative and positive charge. A range of methods is used to produce such materials, almost all of which contain a quaternary cationic surfactants ion a cation.

List of anionic, cationic and non-ionic surfactants

One such well-used class is cationic surfactants alkyl betaines which have a carboxyl group. A long-chain carboxylic acid reacts with a diamine to form a tertiary amine.

On further reaction with sodium chloroethanoate, a quaternary salt is formed: Cationic surfactants are neutral compounds with a cationic and an anionic group which are not adjacent to one another. Amphoteric surfactants are very mild and are used in shampoos and other cosmetics.

They are said to be pH balanced. Applications Laundry detergents A detergent is made up of many ingredients, some cationic surfactants which are surfactants.

An example cationic surfactants the mixture of compounds in a detergent is shown in Table 1. Sir, I thought of preparing carbon foam in my lab.

I'm cationic surfactants master's student. I'm doing work on viscometric study of surfactants under different temperatures but the problem is that being a pakistani student I have to buy the chemicals cationic surfactants my pocket money which is very difficult for me.
