What is anionic and cationic surfactants?

A non-ionic surfactant has no charge groups in its head. The head of an ionic surfactant carries a net charge. If the charge is negative, the surfactant is more specifically called anionic; if the charge is positive, it is called cationic.

Which is example of cationic?

Example of cationic detergents are quaternary ammonium compounds, benzalkonium chloride and cetyltrimethyl ammonium bromide. They will precipitate when mixed with an anionic detergent (soap).

What are surfactants simple definition?

surfactant, also called surface-active agent, substance such as a detergent that, when added to a liquid, reduces its surface tension, thereby increasing its spreading and wetting properties.

What is cationic vs anionic?

An Anionic emulsion has a negative charge, a Cationic emulsion has a positive charge, and a Non-ionic emulsion has no charge.

What is the difference between anionic and cationic?

An anion may be defined as an atom or molecule that is negatively charged. A cation may be defined as an atom or molecule that is positively charged. Anions and cations are both ions. They have an opposite electrical charge, therefore they get attracted to each other.

Which is example of cationic surfactant Mcq?

Quaternary ammonium compounds such as cetyltrimethylammonium bromide (cetrimide), benzethonium chloride and benzalkonium chloride are examples of important cationic surfactants.

What are three types of surfactants?

Types of Surfactants

  • A.
  • Nonionic surfactants – These are surfactants that have no ions.
  • Cationic surfactants – These are positively charged molecules usually derived from nitrogen compounds.
  • Amphoteric surfactants – Those surfactants that change their charge with pH.

What is the use of cationic surfactant?

In detergents, cationic surfactants provide disinfectant, biocidal properties. In water treatment, cationic surfactants are used as ion exchangers to obtain demineralized water. Cationic surfactants offer good corrosion protection and can be good demulsifiers. Cationic surfactants are used as drying aids in carwashes.

Which are cationic detergents?

Cationic detergents are quaternary ammonium salts of chlorides, bromides or acetates. A cationic component of these detergents consists of a long hydrocarbon chain and the nitrogen atom has a positive charge in it.

What are surfactants with examples?

Sodium stearate is a good example of a surfactant. It is the most common surfactant in soap. Another common surfactant is 4-(5-dodecyl)benzenesulfonate. Other examples include docusate (dioctyl sodium sulfosuccinate), alkyl ether phosphates, benzalkaonium chloride (BAC), and perfluorooctanesulfonate (PFOS).

Are cationic surfactants safe?

Cationic surfactants are irritating to mucosa, leading to gastrointestinal upset, but are more likely to cause burns of the mouth, esophagus and stomach than anionic or nonionic surfactants.
