Abstract
Abstract A fiber conditioning composition, of improved fiber conditioning properties, includes an aminosilicone of the amidomethicone type, of a certain formula, and an aqueous medium for the aminosilicone, which serves as a carrier for it. Preferably, the carrier is an aqueous anionic shampoo medium that also contains a cationic surfactant fiber conditioning agent, such as a quaternary ammonium salt, and more preferably it also contains hydrocarbon components, such as microcrystalline wax and petrolatum and/or polyethylene and mineral oil, which promote further improvement in conditioning effects on human hair. The invention is also of fiber conditioning processes and combined shampooing and hair conditoning operations, and of processes for manufacturing the invented conditioning shampoos.
