A liquid detergent composition, particularly suitable for washing dishes, comprises from 30 % to 90 %, by weight, of the total composition of water, and a surfactant mixture comprising i) a 100 % by weight linear, optionally alkoxylated, alkyl sulfate surfactant, and ii) a branched, optionally alkoxylated, alkyl sulfate surfactant, wherein the amount of branched alkyl sulfate surfactant is 10 % to 60 %, by weight, of the total alkyl sulfate surfactant, provided that if either or each of the linear and branched alkyl sulfate surfactants is alkoxylated, the molar weight average degree of alkoxylation is less than 1.4. The compositions have improved viscosity characteristics and good grease and/or suds performance, and are stable at low temperature.

Composition détergente liquide, convenant en particulier pour laver la vaisselle. Cette composition contient de l'eau à raison de 30 % à 90 % en poids de la composition totale, et un mélange tensioactif comprenant i) 100 % en poids d'un tensioactif au sulfate d'allyle linéaire, éventuellement alcoxylé, et ii) un tensioactif au sulfate d'alkyle ramifié, éventuellement alcoxylé. La proportion de tensioactif au sulfate d'alkyle ramifié est comprise entre 10 % et 60 % en poids de la quantité totale de tensioactif au sulfate d'alkyle, à condition que si un ou chacun des tensioactifs au sulfate d'alkyle linéaire ou ramifié est alcoxylé, le degré moyen d'alcoxylation en poids molaire est inférieur à 1,4. Ces compositions présentent des caractéristiques de viscosité améliorées et de bonnes performances en matière de dégraissage et/ou de pouvoir moussant, et sont stables à basse température.
