Polyquaternium-70

Polyquaternium-70, is a cationic polymeric quaternary ammonium polymer which is the preferred choice for many personal care products, such as hair shampoos, due to its film-forming and antistatic properties.

Environmental influences and oxidative hair treatments often result in poorer combability of dry and wet hair. Furthermore, the shine and moisture balance are negatively influenced by the attacked outer structure of the keratinic fibres. Conventional hair care products therefore contain conditioning polymers like cationic polymers or silicone oils (cave: environmental pollution). Conditioning polymers, however, lead to a layer formation on the hair shaft and thus often to a weighting of the hair. This causes problems in hairstyling, especially for people with fine hair (low volume, little hold and fullness of the hairstyle).

Polyquaternium-70 has a high cationic charge density and therefore binds effectively and completely to the negative charges of human hair.

It has been shown that the combination of cationic polymers with a fatty alcohol leads to an intensive conditioning of human hair. Hair conditioned in this way shows excellent wet combability and increased volume in dry condition.

Suitable fatty alcohols are saturated, mono- or polyunsaturated, branched or unbranched fatty alcohols with C6 - C30-, preferably C10 - C22- carbon atoms.
