Abstract
Abstract Hair care uses of polydiorganosiloxanes containing aminoalkyl groups modified by alkoxycarbonylalkyl substituents are described. The modified aminoalkyl silicones exhibit improved deposition on hair and can be formulated into shampoos, conditioners, rinses, creams, gels, aerosol foams or sprays, and permanent waving products.
