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.

Provided is a quaternary ammonium surfmer, that may have the following general formula (I): N.sup.+—R.sup.1R.sup.2R.sup.3R.sup.4 (X.sup.−), where: R.sup.1 and R.sup.2 may independently be H or a C.sub.1-C.sub.3 alkyl, R.sup.3 may be a C.sub.19+ amidoalkyl group, R.sup.4 may be a C.sub.3-C.sub.6 alkyl having a terminal olefin double bond group, and X may be a halogen. Further provided is a method for synthesizing the quaternary ammonium surfmer and a method for recovering hydrocarbons from a subterranean formation that may include injecting a treatment fluid comprising the quaternary ammonium surfmer into the subterranean formation.

The invention concerns synthesized amido-amine-based cationic gemini surfactants with flexible and rigid spacers and different hydrophobic. These gemini surfactants were prepared by modified procedure through amidation of long chain carboxylic acids using 3-(dimethylamino)-1-propylamine followed by treatment with halohydrocarbons and showed excellent thermal stability and surface properties useful for various oilfield applications such as enhanced oil recovery.

Compositions that include cationic surfactants and methods of synthesizing compositions that include cationic surfactants. The surfactants include a quaternary amine and a saturated or unsaturated alkyl chain with 4 to 28 carbons. The surfactants can be generated by reacting a fatty acid modified with an amino alkyl group and an epihalohydrin in the presence of a base. The cationic surfactants can be generated by reacting a fatty acid modified with an amino alkyl group, an epihalohydrin, and a carboxylic acid. The cationic surfactants can be generated by reacting a carboxylic acid, an epihalohydrin, and a catalyst to afford a halo-substituted alkyl ester, followed by reacting the halo-substituted alky ester with a fatty acid modified with an amino alkyl group.
