Abstract:
A composition is provided, including an emulsion of an aqueous phase in a lipophilic phase, wherein the composition includes water, more than 8 wt % butylene glycol, one or more nonionic polysaccharides, and one or more lipophilic materials. The composition may be prepared by a method including the steps of a) mixing the one or more lipophilic materials with an aqueous mixture including water, the one or more nonionic polysaccharides, and the butylene glycol at a temperature in a range from 30 to 70° C. until homogeneity is reached; b) cooling the product of step a) to room temperature; and optionally c) adding ethanol and/or aluminum starch octenylsuccinate to the product of step b) with mixing. A method of caring for a keratin material in an animal includes applying an effective amount of the composition to the keratin material.
