Polyquaternium-11

Polyquaternium-11, also known as PQ-10 polymer, PQ10 compound or cellulose, is a synthetic substance whose applications are mainly found in the cosmetics industry. It is a derivative or modification of cellulose, or plant fibre, which is chemically modified to give it cationic properties. Due to its specific properties, which include the ability to increase the density of cosmetic products, to bind moisture or to form a surface film, Polyquaternium-11 is a frequently used ingredient in many cosmetic products.

The main segment where Polyquaternium-11 is applied is in the production of hair cosmetics. These include hair conditioners and styling products such as gels, waxes, hair sealants, mousses or hair sprays. This substance is able to coat individual hair fibres, thus smoothing them and enhancing their shine, while also contributing to better combing. In addition to hair care, this polymer is also found in skin care products, such as moisturisers and lotions, where it helps retain moisture on the skin's surface. Other products include shower gels, shampoos, deodorants and toothpastes.
