What is polyquaternium salt?

Polyquaternium salt is made of quaternized fatty alkyl grafted on modified natural polymers (such as sugars, cellulose, proteins) or cationic monomers containing double bonds. It is a strong cationic polymer with multiple cationic sites and high relative molecular mass.

Polyquaternium salt has good solubility in water and is a non-oxidizing bactericide flocculant with broad-spectrum and high-efficiency bactericidal and algaecidal ability. It can effectively control the reproduction of bacteria and algae and the growth of slime in water, and has good slime stripping effect and certain dispersion and penetration effects. At the same time, it also has the effects of degreasing, deodorizing and corrosion inhibition.

In hair care, there are many cationic sites in each molecule of polyquaternium salt, which can be firmly adsorbed on the negatively charged surface of the hair protein structure through the attraction of ion electrostatics, so that the fatty hydrocarbon chain is retained on the surface of the hair cuticle. In this way, the fat part deposited on the surface of the hair plays a good conditioning role, making the hair surface smooth, lubricated, soft and easy to comb. At the same time, the conductivity of quaternary ammonium salts can reduce the accumulation of static electricity in the hair, thereby reducing hair flutter and improving hair combing.

Common types of polyquaternium salts

Polyquaternium (Polyquaternium) is a general term for a class of cationic polymers that are often used as ingredients in cosmetics, skin care products, and other personal care products. They come in many different types, and the following are some common types of polyquaternium salts:

Polyquaternium-10: Also known as polyquaternium-10 polymer, it is a cationic polymer commonly used in hair care products, antistatic agents, and conditioners.

Polyquaternium-7: Also known as polyquaternium-7 polymer, it is a cationic polymer commonly used in skin care products, hair sprays, and styling products.

Polyquaternium-28: Also known as citrulline polyquaternium, it is a naturally derived cationic polymer commonly used in skin care products and hair care products.

Polyquaternium-51: Also known as polyquaternium-51 polymer, it is a cationic polymer commonly used in skin care products, hair sprays, and styling products.

Polyquaternium-68: Also known as citrulline polyquaternium-68, it is a naturally derived cationic polymer commonly used in skin care products, hair sprays, and styling products.

Polyquaternium-37: Often used as a thickening emulsifier or thickener. For example, in cosmetics and personal care products, it can help adjust the consistency of the product and improve its stability and feel. In addition, polyquaternium-37 can also be used in combination with cationic preservatives as a cationic thickener, suspending agent, and preparation material for transparent gels. The use of this chemical makes the product more stable and durable.
