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.

Hair products containing dimethyl diallyl ammonium chloride/acrylic

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.

Personal skin care products containing dimethyl diallyl ammonium

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:

Acrylic acid/2-acrylamido-2-methylpropylsulfonic

Alcohols, particularly anhydrous alcohols, thickened with aminomethylated polyacrylamide, used as fracturing fluids for stimulating well production.

Thickened alcohol well treating compositions

Cationic monomers homopolymerized and copolymerized in water-in-oil emulsion systems with crosslinking and branching agents have surprisingly high effectiveness as flocculants and for the treatment of activated sewage sludge.

Emulsion polymerization of cationic monomers

Use of poly (dimethylaminomethyl acrylamide) as a friction reducer for aqueous fluids flowing through a conduit, especially for the aqueous hydraulic fracturing of subterranean formations.
