Abstract: Films which are rapidly soluble in cold and warm water are formed from blends of water soluble polyvinyl alcohol (partially hydrolyzed polyvinyl acetate) and polyacrylic acid. The polymers are compatible and form homogeneous mixtures from which clear, transparent, non-tacky, easily handleable, mechanically strong films can be formed. The films are stable at both low and high humidity conditions, i.e., the films do not become brittle or tacky and retain their high rates of dissolution in water even after being stored in low or high humidity environments at both high and low temperatures. Further, improvements are achieved by incorporating a plasticizer into the polymer blend. The films are also heat sealable and biodegradable.

Abstract: The viscosity of an aqueous alpha-olefin sulfonate detergent composition is reduced by treating such composition, usually at a concentration of 30 to 60%, with a viscosity reducing proportion, usually from 2 to 20%, of a water soluble inorganic halide salt, preferably sodium chloride. By reducing the viscosity, detergent compositions containing the alpha-olefin sulfonate detergent are made more readily pourable, pumpable and sprayable, facilitating their use in liquid detergents and in spray dried particulate form. Because the addition of halide salt may cause separation into different phases it is possible to increase the concentration of the alpha-olefin sulfonate by utilizing the phase richer in content of such detergent material.
