The polysaccharide alkyl ether preferably has a molecular weight of greater than 200,000 and is in particular a guar gum alkyl ether having a degree of substitution of from about 2 to 3, in particular 2.5. The composition can be used in particular in the cosmetics fields for keratinous materials, especially the nails.
