• Aqueous solutions of these compounds are employed in cosmetic, toiletry and detergent compositions for example sharnpoos and'bubble baths and liquid cleaning compositions. Normally these materialsare supplied at 28% active ingredient but in the interests of economy in transport and packaging high concentrations of the order of 50 70% are also commercially available. At these high concentrations they have the texture of a thick paste. in the final formulation they are normally present in an amount less than 30% active in an aqueous solution.
