ABSTRACT:
Biodegradable chemical softening compositions are provided comprising a mixture of a quaternized ester-amine compound and a polyhydroxy compound. Preferred biodegradable quaternized ester-amine compounds include diester dialkyl dimethyl ammonium salts such as diester ditallow dimethyl ammonium chloride, diester di(touch hydrogenated)tallow dimethyl ammonium chloride and diester di(hydrogenated)tallow dimethyl ammonium chloride. Preferred polyhydroxy compounds are selected from the group consisting of glycerol, and polyethylene glycols and polypropylene glycols having a weight average molecular weight from about 200 to 4000.
The biodegradable chemical softening compositions are prepared by first mixing the quaternized ester-amine compound into the polyhydroxy compound at a specific temperature range wherein the polyhydroxy compound is miscible with the quaternized ester-amine compound and then diluting the mixture with a liquid carrier at a specific pH and temperature range to form an aqueous vesicle dispersion suitable for treating fibrous cellulosic material. The biodegradable chemical softening compositions disclosed herein are primarily intended for softening disposable paper products such as tissues and towels. However, the biodegradable chemical softening compositions can also be used to soften fibrous cellulosic materials in textile form.
