POLYQUATERNIUM-88

Safety grade: A

This is a synthetic conditioning polymer that helps mix together ingredients that normally don't blend well, like oil and water. It also thickens products and keeps them stable so they don't separate over time.

It acts as an emulsifier and stabilizer to help create smooth, well-blended formulas while also conditioning hair and skin, and it works as a gentle cleanser.

Graded using: COSING.
