Whatsapp Order

Galsilk (Polyquartenum) is a water-soluble cationic polymer known chemically as Polyquaternium-7. It is widely used as a conditioning agent in personal care and cosmetic formulations, prized for its excellent substantivity to hair and skin, providing softness, smoothness, and antistatic effects. This polymer is typically supplied as a clear to slightly hazy viscous liquid or gel. It is compatible with a broad range of surfactants and ingredients, enhancing the sensory profile of shampoos, conditioners, styling products, and skincare formulations. Galsilk 700 is also valued for its film-forming properties and ability to improve product stability.
