[0298] Stable detergent compositions are obtained, which exhibit good thickening, with a viscosity of at least 4 Pa.Math.s, and a foaming effect, which may be used for cleansing the hair and lead to the production of good cosmetic properties for the hair.

[0299] The compositions exhibit good starting of foaming and generate an abundant foam of good quality: the foam in particular has a creamy texture and spreads easily over the whole head of hair.

[0300] Examples 4 and 7 were tested by a sensory panel of 10 trained consumers and compared with a sulfate-free commercial shampoo formulation.

[0301] The two examples according to the invention exhibit starting of foaming and foam abundance, firmness and persistence equivalent to those of the commercial product, even though these compositions according to the invention comprise much less anionic surfactant (between 10% and 30% less).
