Abstract
Betaine/cocoamide complexes are produced by providing an aqueous solution of a cocoamide selected from the group comprising coconut oil fatty amides and an alkaloid selected from the group consisting of betaines and emulsifying said aqueous solution to form the betaine/cocoamide complexes. Surfactant compositions are produced by combining the betaine/cocoamide complexes with a surfactant. The betaine/cocoamide complexes provide improved lather and conditioning properties and lower cloud/clear points to the compositions produced.

A conditioning agent comprising a betaine/cocoamide complex formed from an emulsification of a betaine and a cocoamide, having a melting point at or about 90.degree. C., selected from the group consisting of cocomonoethanolamides which contain chain length distributions of C8 to C18 or cocoisopropanolamides which contain chain length distributions of C12 to C18;
- wherein an emulsion is formed by heating to temperatures at or above the melting point of said cocoamide and said emulsion is then cooled below the melting point of said cocoamide to set the betaine/cocoamide complex.
A surfactant composition comprising 0.5 to 13 wt. % of a betaine/cocoamide complex and 5 to 25 wt. % of an additional surfactant, wherein said betaine/cocoamide complex is formed from an emulsification of a betaine and a cocoamide, having a melting point at or above 90.degree. F., selected from the group consisting of cocomonoethanolamides which contain length distributions of C8 to C18 or cocoisopropanolamides which contain chain length distributions of C12 to C18;
- in which an emulsion is formed by heating to temperatures at or above the melting point of said cocoamide and said emulsion is then cooled below the melting point of said cocoamide to set the betaine/cocoamide complex, said betaine/cocoamide complex is then combined with said additional surfactant.
