Liquid detergent compositions are presented which comprise anionic surfactants selected from the group of alkyl alkoxy sulfates and alkyl sulfates wherein at least 25 %, by weight of said anionic surfactant, is alkyl sulfates; and from about 0.1 % to about 5 % of an amine cosurfactant of formula (a) wherein R1 is a C8-C16 alkyl group; n is from about 2 to about 4, X is a bridging group which is selected from NH, CONH, COO, or O; x is 0 or 1; and R3 and R4 are individually selected from H, C1-C4 alkyl, or (CH2-CH2-O(R5)) wherein R5 is H or methyl.
L'invention porte sur des compositions de détergents liquides comprenant des tensioactifs anioniques choisis dans un groupe composé d'alcoxy sulfates d'alkyle et de sulfates d'alkyle. Dans ces compositions, 25 % en poids dudit tensioactif anionique sont des sulfates d'alkyle, et environ 0,1 % à environ 5 % sont un co-tensioactif aminé représenté par la formule (a), dans laquelle R¿1? représente un groupe alkyle en C¿8?-C¿16?; n varie d'environ 2 à environ 4; X est un groupe de pontage choisi parmi NH, CONH, COO ou O; x représente 0 ou 1; et R¿3? et R¿4? sont choisis chacun séparément entre H, alkyle en C¿1?-C¿4?, ou (CH¿2?-CH¿2?-O(R¿5?)), où R¿5? représente H ou méthyle.
