Representative non-ionic detergents include, for instance, esters of polyols and sugars, condensation product of ethylene oxide on fatty acids, on fatty alcohols, on long chain alkylphenols, on long chain mercaptans, on long chain amides and polyethers of polyhydroxylated fatty alcohols.

Representative amphoteric detergents include, for instance, asparagine, condensation products of monochloroacetic acid on imidazolines, alkyl amino propionates, betain derivatives or amine oxides.

These shampoo compositions contain generally from 0.1 to 15%, but preferably, from 1 to 10% by weight of the active compound based on the total weight of the composition. They also contain for example from 4 to 20%, but preferably, from 5 to 10% by weight of detergents in solution in an aqueous medium.

The shampoos such as defined above can also contain conventional cosmetic components such as perfumes and dyes. They can also contain thickening agents such as alkanolamides of fatty acids, cationic polymers such as the copolymers of quaternized vinylpyrrolidone, cationic cellulose polymers, cellulose derivatives such as carboxymethyl or hydroxymethyl cellulose, esters of long chain polyols, and natural gums, whereby the composition can be provided in the form of a cream or gel.

Additionally, these shampoos can be provided in the form of powders which can either be applied to wet hair, or can be solubilized in a suitable volume of water before washing the hair.

These shampoo compositions can also include dyes and thus be employed to color the hair.

Generally, satisfactory results can be obtained by a weekly application of the shampoo, which results in a significant reduction and, in certain cases, essentially complete elimination of the oily appearance of the hair, while at the same time providing normal care of the hair.

The present invention also relates to a composition containing the active compound, as defined above, together with a suitable skin-compatible cosmetically acceptable vehicle, which composition can be applied to the skin to improve its appearance.
