Publication number: 20220356390Abstract: The invention relates to a dynamic method for determining the formation of a Winsor III microemulsion system, the method comprising the steps of: providing a mixture of an aqueous medium and a hydrocarbon medium in a chamber; continuously altering the concentration of at least one component in the mixture, while the ratio of the aqueous medium to the hydrocarbon medium remains constant and while stirring the mixture; and continuously measuring at least one physicochemical property of the mixture. The invention further relates to a device for determining the formation of a Winsor III microemulsion system.Type: ApplicationFiled: September 9, 2019Publication date: November 10, 2022Applicants: CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE, ECOLE NATIONALE SUPERIEURE DE CHIMIE DE LILLE, UNIVERSITE DE LILLE, TotalEnergies OneTechInventors: Guillaume Lemahieu, Jesus Fermin Ontiveros, Jean-Marie Aubry, Valérie Molinier

Patent number: 11052025Abstract: Disclosed is a microemulsion of oil-in-water type including, preferably consisting of, by weight relative to the total weight of microemulsion: •70% to 94% of water, •1% to 15% of at least one hydrophobic fragrancing substance, •4% to 20% of at least one preferably volatile solvo-surfactant, and •0.1% to 15%, preferably 1% to 13%, of at least one hydrotropic agent or at least one surfactant selected from anionic surfactants, cationic surfactants, amphoteric surfactants and non-ionic surfactants. The solvo-surfactant is selected from monoalkylated glycerol derivatives of following formula (I): wherein the “alkyl” group is a linear or branched alkyl group including from 1 to 8 carbon atoms, and R and R? are each independently H or a linear or branched alkyl group including from 1 to 5 carbon atoms, with the proviso that R is different from R?, and mixtures thereof.Type: GrantFiled: June 1, 2017Date of Patent: July 6, 2021Assignees: CHANEL PARFUMS BEAUTE, UNIVERSITE DE LILLEInventors: Oriana Boucenna Verdier, Christian Mahe, Véronique Rataj-Nardello, Jean-Marie Aubry, Maxime Nollet, Raphaël Lebeuf
