What is cationic Esterquat surfactant?
2 Cationic Surfactants. Esterquats, quaternary ammonium compounds containing cleavable ester bonds to conjugate fatty acyl groups to a polar group containing the quaternary ammonium head group, are the most commonly used biobased cationic surfactant.
Which is an example for cationic surfactants?
Cationic surfactants are essentially quaternary ammonia compounds with positively charged surface-active moieties (e.g. benzalkonium, benzethonium, methylbenzethonium, cetylpyridinium, alkyl-dimethyl dichlorobenzene ammonium, dequalinium and phenamylinium chlorides, cetrimonium and cethexonium bromides).
What is cationic surfactants used for?
In detergents, cationic surfactants are used as cleaning enhancers in addition to anionic surfactants. They have excellent fat dissolving properties. In fabric softeners they are used as antistatic agents and finishing agents.
Why cationic surfactants is suitable as fabric detergent?
Cationic surfactants have a positively charged nitrogen atom and at least one hydrophobic, long-chain substituent in the molecule. Because of their fabric-softening and antistatic properties, they are used as active materials in fabric-softening agents.
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 the formula of cationic detergent?
It is usually the quaternary ammonium salts with the chlorides, bromides or acetates carrying the negative charge. So, the CTAB, that is, cetyltrimethylammonium bromide, [H3C−(CH2)15−⊕N−(CH3)3]Br− is a cationic detergent.
How do cationic detergents work?
A cationic detergent is most likely to be found in a shampoo or clothes “rinse”. The purpose is to neutralize the static electrical charges from residual anionic (negative ions) detergent molecules. Since the negative charges repel each other, the positive cationic detergent neutralizes this charge.
