A structured surfactant composition containing one or more branched alkyl (ether) sulfates according to the formula: RO(CH2 CH2O)n SO3M, wherein R is branched (C8-C18)alkyl or branched (C8-C18)alkenyl, n has an average value of from 0 to about 7 and M is a solubilizing cation, provided that M cannot be sodium if n is greater than or equal to 1, and a structurant, wherein the composition exhibits non-Newtonian shear thinning viscosity and is capable of suspending insoluble or partially insoluble components.

L'invention concerne une composition de tensio-actif structurée comprenant : un ou plusieurs sulfates d'alkyle (éther) ramifiés de formule RO(CH¿2? CH¿2?O)¿n? SO¿3?M, dans laquelle R désigne un alkyle (C¿8?-C¿18?) ramifié ou un alcényle (C¿8?-C¿18?) ramifié, n présente une valeur moyenne comprise entre approximativement 0 et approximativement 7, et M désigne un cation de solubilisation, à condition que M ne puisse pas représenter sodium si n est supérieur ou égal à 1, et ; un structurant. La composition selon l'invention présente une viscosité de fluidification au cisaillement non newtonienne et peut tenir en suspension des composants insolubles ou partiellement insolubles.
