Which of the following cationic detergent?

Glyceryl oleate.

Detergents are classified into three main types: cationic, anionic, and non-ionic.

Cationic detergents have a positively charged head group and a negatively charged tail group. The head group is attracted to negatively charged surfaces, such as skin and hair. The tail group is attracted to oil and grease. This makes cationic detergents effective at cleaning surfaces and removing oil and grease.

Anionic detergents have a negatively charged head group and a positively charged tail group. This makes them effective at cleaning surfaces, but they are not as effective at removing oil and grease as cationic detergents.

Non-ionic detergents do not have a net charge. They are effective at cleaning surfaces, but they are not as effective at removing oil and grease as cationic or anionic detergents.

The four detergents you mentioned are all classified as anionic detergents. They have a negatively charged head group and a positively charged tail group. This makes them effective at cleaning surfaces, but they are not as effective at removing oil and grease as cationic detergents.

Glyceryl oleate is a special type of anionic detergent that is made from glycerol and oleic acid. It is a very mild detergent that is often used in personal care products, such as soaps and lotions.
