What are cationic surfactant?
What are cationic surfactants? Surfactants are substances that reduce the surface tension of a liquid or the interfacial tension of two phases. Cationic surfactants are surfactants that have a positively charged functional group. Like any surfactant, cationic surfactants are composed of a polar and a non-polar part.
What is an example of cationic surfactant?
Cationic surfactants have a positive charge on their hydrophilic end. The positive charge makes them useful in anti-static products, like fabric softeners. Examples of some common cationic surfactants include alkyl ammonium chlorides.
What is a cationic surfactant Mcq?
Explanation: Cationic surfactants are organic molecules where the water-soluble group is positively charged. A surfactant has two parts in it. One part is soluble in oil and another part is soluble in water. The molecule thus is partially soluble in both water and oil.
What is cationic detergent with example?
Cationic detergents are more strongly absorbed on fabrics that are anionic or nonionic surfactants. They are used as wetting agents, fabric softeners, bacteriostats and emulsifiers. Example of cationic detergents are quaternary ammonium compounds, benzalkonium chloride and cetyltrimethyl ammonium bromide.
What is cationic solution?
Cationic detergents, which produce electrically positive ions in solution. Nonionic detergents, which produce electrically neutral colloidal particles in solution. Cationic detergents contain a long-chain cation that is responsible for their surface-active properties.
What is the formula of cationic detergent?
So, the CTAB, that is, cetyltrimethylammonium bromide, [H3C−(CH2)15−⊕N−(CH3)3]Br− is a cationic detergent. – Anionic detergents have a long hydrocarbon chain with its soluble end with the negative charge. Like in the sodium salt of long-chain sulfonated alcohols or hydrocarbons.
