Abstract: The present invention is directed at mono-, di- or polyquaternary ammonium compounds of the formula (I) wherein x is 1 to 50, and F can be the same or different and is represented by the general formula (II) wherein at least one of the optionally substituted and optionally functional-group-containing hydrocarbon radicals R1, R2, R3, R4 or R5 contains at least one estolide moiety comprising two or more ester or amide moieties. The invention also relates to a process for the synthesis of such compounds, the use of the compounds in cosmetic formulations for skin and hair care, cosmetic compositions for the treatment of fibers, and compositions containing one or more of the compounds for the treatment of hair.

Abstract: The present invention is directed at hair care formulations comprising at least one non-ionic compound containing at least one terminal estolide moiety, at non-ionic compounds containing at least one terminal estolide moiety, the use of non-ionic compounds containing at least one terminal estolide moiety in cosmetic formulations for skin and/or hair care, the use of non-ionic compounds containing at least one terminal estolide moiety for the treatment of fibers, and at compositions containing at least one such compound for the treatment of hair.

Abstract: The present invention is directed at organic ammonium salts comprising an organic ammonium-group-comprising cation which does not contain an estolide moiety and a carboxylate anion (COO—) group-comprising anion selected from the group consisting of anions containing at least one estolide moiety or carboxylate anions containing at least one internal ester group. The invention is also directed at a process for the production of such organic ammonium salts, the use of such organic ammonium salts in cosmetic formulations for skin and hair care, the use of such organic ammonium salts for the treatment of fibers, the use of the organic ammonium salts for the treatment of hair, at compositions containing such organic ammonium salts, the use of the products of the process for the production of organic ammonium salts in cosmetic formulations for skin care and hair conditioner and hair shampoo, the use of said products for the treatment of fibers, and compositions containing said products for the treatment of hair.
