Abstract: The object of the invention concerns a quaternary ammonium salt of formula (I) wherein the substituents R5, R6 are independently chosen between hydrogen H and a radical R0, wherein the radical R0 consists of the structure of formula (II) wherein the substituent R1 is chosen from the group consisting of: hydrogen, methyl, isopropyl, sec-butyl, isobutyl, ethylenemethylthio, benzyl, para-hydroxybenzyl and 3-methylene-1H-indole, wherein the substituents R2, R3, R4 are independently chosen from the group consisting of: methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, sec-butyl and tert-butyl, wherein m is an integer number comprised between 1 and 22, wherein the counteranion X? is chosen from the group of carboxylic acids consisting of: formic acid, acetic acid, unsaturated monocarboxylic acids, tartaric acid, adipic acid, aldaric acid, oxalic acid, phthalic acid, azelaic acid, sebacic acid, malonic acid, succinic acid, glutaric acid, pimelic acid, maleic acid, malic acid, fumaric acid, suberic acid, citric

Abstract: This patent application relates to the use of an aliphatic ester of a polyglycerol phosphate as an emulsifier for the preparation of compositions for trichological use, wherein the polyglycerol has a number of monomeric units comprised between 4 and 20; the phosphate ester is a polyglycerol monoester; the aliphatic ester is an polyglycerol ester with one or more fatty acid molecules selected from the group consisting of saturated, monounsaturated and polyunsaturated fatty acids with a number of carbon atoms comprised between 4 and 22 or their ester derivatives.

Abstract: The object of the present invention concerns a hair restructuring association comprising or alternatively consisting of: (a) a quaternary ammonium salt of formula (I) and (b) at least one sulpho-derivative of vegetable fatty acids, wherein R5, R6 are independently chosen between hydrogen and a radical R0, R0 consists of the following structure of formula (II), R1 is chosen from the group consisting of: hydrogen, methyl, isopropyl, sec-butyl, isobutyl, ethylenemethylthio, benzyl, para-hydroxybenzyl and 3-methylene-1H-indole, R2, R3, R4 are independently chosen from the group consisting of: methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, sec-butyl and tert-butyl, mX? is chosen from the group consisting of: formic acid, acetic acid, unsaturated monocarboxylic acids, adipic acid, aldaric acid, oxalic acid, phthalic acid, azelaic acid, sebacic acid, malonic acid, succinic acid, tartaric acid, glutaric acid, pimelic acid, maleic acid, malic acid, fumaric acid and suberic acid, isocitric acid, citric acid, fa

Abstract: An ester of glycyrrhetinic acid with (poly)glycerol-sorbitol and cosmetic compositions thereof is described. The introduction of sorbitol in the (poly)glycerol chain determines an increase in solubility of the ester of the invention increasing solubility in water and the possibility of using glycyrrhetinic acid in cosmetic applications.

Abstract: A polyglycerol-azelaic acid polyesters and cosmetic compositions that incorporate them as active components in combination with a cosmetically acceptable vehicle. A process for producing esters and polyesters between azelaic acid and glycerol or oligomers thereof containing up to 10 monomer units.
