Polyquaternium-11 provides shine, detangling and de-frizzing benefits to hair  conditioners and shampoos by coating the hair in a clear film that adds visible and sensorial volume


Polyquaternium-11 is a quaternary ammonium compound that forms flexible films with mild conditioning benefits in rinse off and styling applications.

Use as a conditioning agent in shampoos and cream or clear rinse conditioners. Provides instant detangling whilst adding volume and body to the hair. It makes the hair easier to comb.

Particularly effective in hair styling products, including spray on conditioners and detanglers. Excellent for use with blow drying and straighteners where it can provide thermal protection for the hair.

Polyquaternium-11 can be used in skincare products also for improved skin feel. PQ-11 works well in shaving products, skin creams and lotions, liquid soap and bars of soap.

Polyquarternium when used in a foaming product such as a shampoo or shower gel will enhance the foam levels. PQ-11 is compatible with with non-ionic, anionic and amphoteric surfactants and rheology modifiers. PQ-11 is excellent combined with carbomer to produce smooth and easily applied gels.

PQ-11 can enhance the stability of surfactant, cream and lotion based formulations.

How to Use

Polyquaternium-11 is supplied as a viscous liquid, though supplied in a jar for ease of use as the liquid is very thick. Gently warming can help with the usability in formulation.

Polyquarternium-11 is readily dissolved in water and thus it is easiest to dissolve into the water stage of formulation. When used in surfactant based formulation we advise adding the PQ-11 before surfactants for ease of dispersal.

When formulating in hot process applications, add to the water phase and disperse. PQ-11 is resilient to heat.

Please never throw empty packaging in the bin. Always recycle your Plastic packaging in the relevant facilities. All of our Plastic Packaging is either PET, PP or HDPE Plastic, so can be readily recycled in household recycling facilities or local plastic waste recycling. If plastic is recycled it still remains one of the most environmentally friendly packaging materials available. Our Glass and Aluminium can be readily recycled in standard household recycling facilities.
