The present invention relates to bar compositions comprising a mixture of higher melting point and lower molecular weight (100 to about 1400) lower melting point polyalkylene glycol(s) in which use of the lower molecular weight polyalkylene glycol or glycols allows enhanced rates of extrusion from the plodder.

Mild bar compositions comprising blends of higher melting point

The invention describes detergent bar compositions comprising liquid silicone compounds or emulsions of said compounds which are used in relatively small levels as processing aids. These compounds allow pellets coming off a chill roll or refiner to be less tacky such that they do not readily clog machinery when the pellets are transferred to silos.

Soap bar composition comprising low levels of silicone as processing aids

The present invention relates to solid compositions comprising acyl isethionate and betaines, to compositions comprising acyl isethionate and amidosulfosuccinate, and to compositions comprising acyl isethionate, betaine and amidosulfosuccinate.

Acyl isethionate skin cleaning compositions containing betaines, amido

An aqueous based personal washing product is disclosed which when used has good cleaning ability and is particularly mild to the skin. The liquid product, containing a selected blend of surfactants and emollients, including long chain fatty acids, free isethionate salts and acyl-isethionates is particularly adapted for facial washing.

Aqueous based personal washing cleanser

An aqueous based personal washing product is disclosed which when used has good cleaning ability and is particularly mild to the skin. The free flowing liquid product, containing a selected blend of surfactants and emollients, including long chain fatty acids, free isethionate salts and acylisethionates is particularly adapted for facial washing.

A batch and continuous process is disclosed for the production of a composition comprising alkali metal salts of C.sub.8 -C.sub.22 alkyl fatty monocarboxylic acid and C.sub.8 -C.sub.22 acyl isethionate in a ratio of 20:1 to 1:0.98. Both batch and continuous routes require that the saponifying aqueous caustic solution includes sodium hydroxide and sodium isethionate maintained as a hot solution at a temperature of from 180.degree. F. to about 200.degree. F. For the batch route, the sequence of steps require the caustic solution to be added slowly to the fatty acid. In the continuous process, it is advantageous to introduce fatty acid upstream from the point where the caustic solution stream enters the mixing chamber.

Process for preparing soap-acyl isethionate compositions

A skin cleansing composition is provided that includes a combination of C.sub.16 -C.sub.18 acyl isethionate ester salts having no more than 25% C.sub.14 or lower acyl groups with at least one co-active surfactant. The weight ratio of acyl isethionate to co-active will range from about 20:1 to about 1:1. Soap is present in an amount no higher than 10% by weight of the composition.
