Polyquaternium-11 is a quaternized conditioning polymer well known for hair conditioning and film forming properties. 

In hair conditioners and shampoo products, Polyquaternium-11 helps provide shine, detangling and de-frizzing benefits by coating the hair with a clear film that adds visible and sensorial volume.  It will also provide light hold in styling products such as fixative sprays, hair mousses and gels.

Polyquaternium-11 can be used in skincare products also for improved skin feel,  working well in shaving products, skin creams and lotions, liquid soaps and shower gels. When used in a foaming product such as a shampoo or shower gel, the Polyquaternium-11 will enhance the foam levels and is compatible with with non-ionic, anionic and amphoteric surfactants and rheology modifiers. Polyquaternium-11 can also be combined with carbomer to produce smooth and easily applied gels.
