(57) [Summary]nThe present invention relates to personal cleaning bar compositions, particularly (1) foaming anionic surfactants (e.g., sodium acylisethionate or fatty acid soaps) and (2) certain solid low moisture absorbing amphoteric surfactants (e.g., N- Disodium lauryliminodipropionate). The present invention relates to the incorporation of large amounts of said solid amphoteric surfactants into certain bar compositions to obtain excellent skin hypoallergenicity and bar use characteristics. The present invention is particularly directed to the advantages of using solid low moisture absorbing amphoteric surfactants to overcome processing difficulties in extrusion and improved extrusion processes. |
