Gafquat™ HSi conditioning solution INCI Name: Polyquaternium-28 (and) Dimethicone

Gafquat HSi conditioning solution is a methacrylamidopropyl trimethylammonium chloride (MAPTAC) copolymer using a unique shell/core structure. Gafquat HSi conditioning solution combines the benefits of both film forming polymers and dimethicone in personal care products, while minimizing drawbacks associated with silicones (greasy feel, build-up).
This allows for stable formulation of water-insoluble silicone in aqueous products, compatibility with anionic surfactants, foam stabilization, and good stability during storage.
