Abstract (en)

Water in oil or oil in water emulsion (I) comprises: an oily phase comprising one or more oils of vegetable, mineral and/or synthetic origin, at least one nonionic and/or anionic emulsifying surfactant; and an aqueous phase comprising water and at least one phyllosilicate (I). Water in oil or oil in water emulsion comprises: an oily phase comprising one or more oils of vegetable, mineral and/or synthetic origin, at least one nonionic and/or anionic emulsifying surfactant; and an aqueous phase comprising water and at least one phyllosilicate of formula (Na +> 0 . 7[(Si 8Mg 5 . 5Li 0 . 3)O 2 0(OH) 4] -> 0> 7>). Independent claims are included for: (1) concentrated water in oil or oil in water emulsion comprising at least one or more oils of vegetable, mineral and/or synthetic origin and a nonionic and/or anionic emulsifying surfactant and the phyllosilicate, previously dissolved in a minimum water to obtain a gel or fluid sol, where the dilution allows to obtain (I); (2) preparing (I) comprising: preparing the oily phase by mixing the components comprising at least one or more vegetable, mineral and/or synthetic oils and an anionic and/or ionic emulsifying surfactant in oily phase; preparing the aqueous phase by mixing the components comprising at least water and the phyllosilicate; and mixing continuously or in batch, the oily phase and the aqueous phase in a dissolver; and (3) preparing a concentrate by a water in oil or oil in water emulsion comprising: dissolving the phyllosilicate in a minimum of water to form a gel or fluid sol; mixing at least one or more vegetable and/or mineral and/or synthetic oils and a nonionic and/or anionic emulsifying surfactant of the oily phase; and mixing the mixtures.

Abstract (fr)

La présente invention concerne une émulsion eau dans huile (e/h) ou huile dans l'eau (h/e) composée d'une phase huileuse comprenant une ou plusieurs huiles d'origine végétale et/ou minérale et/ou de synthèse, au moins un tensio-actif émulgateur non ionique et/ou anionique, et une phase aqueuse comprenant de l'eau, caractérisée en ce que la phase aqueuse comprend au moins un phyllosilicate, de sorte à obtenir une émulsion fluide et stable dans le temps. La présente invention se rapporte également à l'utilisation et au procédé de préparation de l'émulsion susmentionnée. La présente invention concerne aussi un concentré de l'émulsion susmentionnée, ainsi que son procédé de fabrication.
