Abstract: This invention relates to improved hair products which contain dialkyl diallyl ammonium chloride/acrylic acid-type polymers. These polymers provide exceptional conditioning properties to hair products such as shampoos, conditioners, rinses, bleaches, hair dyes and hair sprays.

Abstract: This invention relates to improved personal skin care products which contain dimethyl diallyl ammonium chloride/acrylic acid-type polymers. These polymers provide exceptional feel to skin when personal skin care products containing them, such as hand and face lotions, soaps or creams, suntan lotions, bubble baths, shaving creams, antiperspirants, and deodorants, are used.

Abstract: The present invention is directed to a method of inhibiting corrosion and the precipitation of scale-forming salts in an aqueous system, comprising adding to the system at least 0.1 mg/l of a polymer having an intrinsic viscosity of 0.05 to 4.5 dl/g, in 1.0 M NaCl, prepared from:(A) 35 to 65%, by weight, of acrylic acid or methacrylic acid;(B) 15 to 45%, by weight, of 2-acrylamido-2-methylpropylsulfonic acid or 2-methacrylamido-2-methylpropylsulfonic acid; and(C) 15 to 25%, by weight, of 2-acrylamido-2-methylpropyl phosphonic acid or 2-methacrylamido-2-methylpropylphosphonic acid.
