Polyquaternium 7 is a water-soluble cationic copolymer. Polyquaternium 7 is conditioning, and it has an absolutely incredible skin and hair feel. In hair products, it gives substantivity without build-up and improves comb-through. It is advertised as having “very good compatibility with many anionic surfactants”, making it useful in body washes and shampoos. Generally speaking, it makes your projects feel divine and leaves skin and hair feeling silky smooth and conditioned without any hint of greasiness. It also functions as a film former, helping keep the skin and hair moisturized.
