Abstract
A new rinse-free shampoo has been developed. The shampoo includes a biodegradable absorbent formed of a cross-linked carboxymethylcellulose which allows a higher water content than conventional shampoos. The soaps used in the shampoo to provide the cleaning action are preferably lauric acid derivatives, including ammonium derivatives. The shampoo leaves less residue than conventional rinse-free shampoos.
