Abstract
The following are described herein: a composition that consists of a mixture that comprises at least amides, amines, ester-amides, ester-amines, amine salts and monoglycerides, that are all derived from monomeric, dimeric, trimeric and/or tetrameric fatty acids; a process for the production of said composition which comprises the transamidification reaction of a polyunsaturated vegetable oil that is polymerized thermally, with an excess of at least one amino alcohol, which may or may not be in the presence of a catalyst; and the uses of this composition particularly as an emulsifying agent that allow it, depending on the nature of the oil, to form an oil-in-water or water-in-oil emulsion, as a solid-dispersing agent, or as an agent for the stabilization of foams in a liquid or an emulsion.
