Polyquaternium-7

Polyquaternium-7 is a polymer that is often used in the formulation of a variety of personal care products. It is a cationic polymer, which means it carries a positive charge. This property allows it to neutralize the negative charges found on hair and skin, providing benefits such as improved texture and feel, enhanced moisturization, and increased antistatic effects.

Chemical Structure

Polyquaternium-7 is a copolymer of acrylamide and the quaternary ammonium salt diallyldimethylammonium chloride (DADMAC). The ratio of acrylamide to DADMAC can vary, which allows for the customization of the polymer's properties to suit specific applications.

Uses

Polyquaternium-7 is widely used in the formulation of a variety of personal care products, including shampoo, conditioner, body wash, and skin care products. It is valued for its ability to improve the texture and feel of these products, as well as for its moisturizing and antistatic properties.

In hair care products, Polyquaternium-7 helps to smooth the hair cuticle, reducing frizz and enhancing shine. It also helps to detangle the hair, making it easier to comb and style.

In skin care products, Polyquaternium-7 helps to moisturize the skin and improve its texture. It also has mild antiseptic properties, which can help to prevent the growth of harmful bacteria on the skin.

Safety

Polyquaternium-7 is considered safe for use in personal care products. It is non-toxic and non-irritating, and it has been approved for use by regulatory bodies such as the U.S. Food and Drug Administration (FDA) and the European Union (EU).
