  • Patent number: 8937102
    Abstract: The invention is drawn to fluid concentrate formulations of fatty acid monoethanolamides comprising (a) about 71-76% by weight of one or more C8-C22 fatty acid monoethanolamides, (b) about 15-17% by weight of water, and (c) about 10-12% by weight of one or more hydrotropes, based on the fluid formulation, wherein the fluid formulation is homogeneous, pumpable and color stable at a temperature of less than 55° C. A preferred embodiment is drawn to fluid concentrate formulations of cocamide monoethanolamide (CMEA) consisting of (a) about 71-76% by weight of CMEA, (b) about 15-17% by weight of water, and (c) about 10-12% by weight of glycerol, based on the fluid formulation. Methods of preparing the fluid concentrate formulations mulations are also disclosed. The fluid concentrate formulations of fatty acid monoethanolamides are useful in the preparation of cosmetic and pharmaceutical compositions.
