The present invention relates to a one-phase microemulsion that contains an emulsifier system containing a branched alkyl glycoside of the formula (I): R1OGn, where R1 is a branched alkyl group containing 8-16 carbon atoms, G is a saccharide residue and n, the degree of polymerisation, is between 1-5, and optionally a linear alkyl glycoside with the formula (II): R2OGn, where R2 is a linear alkyl group containing 6-18 carbon atoms, G is a saccharide residue and n is between 1-5, a water insoluble oil component, water and, if needed, minor amounts of a cosurfactant/cosolvent. This microemulsion may be used e.g. in a cleaning process for removal of hydrophobic substances from hard surfaces or textile, and in personal care of pharmaceutical formulations.
La présente invention concerne une microémulsion monophase qui contient un système émulsifiant contenant un glycoside d'alkyle ramifié de la formule (I): R¿1?OG¿n?, où R¿1? est un groupe alkyle ramifié contenant 8-16 atomes de carbone, G est un résidu de saccharide et n, le degré de polymérisation, vaut 1-5 ; éventuellement un glycoside d'alkyle linéaire avec la formule (II): R¿2?OG¿n?, où R¿2? est un groupe d'alkyle linéaire contenant 6-18 atomes de carbone, G est un résidu de saccharide et n vaut 1-5 ; un composant huile insoluble dans l'eau ; de l'eau et éventuellement un cosurfactant/cosolvant en faible quantité. Cette microémulsion peut être utilisée notamment dans un procédé de nettoyage destiné à enlever des substances hydrophobes de surfaces dures ou de textiles, et dans les formulations d'hygiène corporelle ou pharmaceutiques.
