Abstract
The present invention relates to personal wash bar compositions, particuly compositions comprising (1) lathering anionic surfactants (e.g., sodium acyl isethionate or fatty acid soap); (2) specific solid, less hygroscopic amphoteric surfactants (e.g., disodium N-lauryl iminodipropionate). The invention relates to the incorporation of significant levels of said solid amphoteric surfactant into the specific bar compositions to achieve superior skin mildness and bar user properties. The invention especially addresses the advantages of using solid, less hygroscopic amphoteric surfactants to reduce the processing difficulties in extrusion and modified extrusion processes.
