Kester Wax BK-40 #197

Kester Wax BK-40 is a high molecular weight branched ester. BK-40 is hard and brittle with a low melt point. These attributes impart a creamy texture and help to improve skin moisture without adding greasiness like many butters. Kester Wax BK-40 mimics the textures of butters and hydrogenated chemistries without the oxidation and rancidity issues. Formulators will find it builds viscosity and improves esthetics in emulsions. BK-40 can be used in all cosmetic, skin and hair applications without limit.
