Abstract: Water-dispersible solid compositions that comprise at least one water-soluble polysaccharide, and at least one quaternary ammonium compound, amine, or protonated amine compound as an active ingredient that is absorbed by the polysaccharide are disclosed. The compositions are useful for a wide variety of applications, such as fabric softener compositions, hair care compositions, sanitizing compositions, and well bore treatment compositions.

Abstract: Clear, stable concentrated liquid compositions are disclosed that comprise from 30% to 90% by weight of an esterquat active, and from 10% to 50% by weight of a particular solvent system. The esterquat active is the quaternized reaction product of a fatty acyl source having an Iodine Value of 40 to 130 reacted with an alkanolamine at a fatty acyl to alkanolamine molar ratio of 1.0:1 to 2.2:1. The concentrated liquid compositions have a VOC content of less than 5%, a Biorenewable Carbon Index (BCI) of at least 20 and a viscosity of less than 5000 cP at 25° C. The concentrated liquid compositions can be easily diluted in water to form stable aqueous dispersions.
