A cleansing system comprises a synthetic detergent bar and a pouf/sponge for holding the bar. By using pouf, it has been found that lather can be enhanced, even in compositions comprising lather depressing emollients. The system also helps decrease perception of mush. A preferred emollient of the invention comprises emollient/oil.

Cleansing system comprising synthetic detergent bar and pouf

The present invention relates to synthetic bar compositions comprising amphoteric surfactants (e.g., betaine) in which, by using floor levels of fatty acid soap and floor ratios (minimum amounts) of saturated to unsaturated soap, enhanced processing (i.e., measured as rates of extrusion) is obtained at higher levels of amphoteric.

Enhanced processing of synthetic bar compositions comprising amphoterics based on minimal levels of fatty acid soap and minimum ratios of saturated to unsaturated soap

Enhanced processing of synthetic bar compositions comprising amphoterics

The invention relates to a cleansing system comprising a synthetic detergent bar and a pouf/sponge for holding the bar. By inserting bar inside the pouf, it has been found that lather can be enhanced, even in compositions comprising lather depressing emollients. The bar holder and bar system also help decrease perception of mush.

An aqueous fabric conditioning composition comprising a homogeneous dispersion of fabric conditioning active particles having a size distribution such that the particles have a mean size of about 0.7 to 10 microns as measured by Malvern Particle Size Analyzer and preferably have 10% of the distribution with a particle size of at least 23% of the mean particle size. The composition is obtained by a continuous process for making the aqueous fabric conditioning composition.

Fabric conditioning compositions and process for making them

An aqueous fabric conditioning composition comprising a homogeneous dispersion of fabric conditioning active particles having a size distribution such that the particles have a mean size of about 0.7 to 10 microns as measured by Malvern Particle Size Analyzer and preferably have 10% of the distribution with a particle size of at least 23% of the mean particle size. A second aspect of the invention relates to a continuous process for making the aqueous fabric conditioning composition.

Isethionate salts have been discovered to provide protection for the skin against damage from contact with soap or other surfactants. A mild to the skin cleaning composition is provided comprising fatty acid soap in amounts greater than 25% and an isethionate salt such as sodium isethionate, the ratio of soap to isethionate ranging from 1:2 to abut 200:1. Sodium C.sub.8 -C.sub.18 acyl isethionate may be incorporated as a further component into the cleaning composition, although in an amount not to exceed that of the soap.

Cleaning compositions with skin protection agents

A process is disclosed for preparing a toilet bar composition whose components comprise a fatty acid soap and a C.sub.10 -C.sub.16 acyl isethionate salt in the ratio of about 20:1 to 1:0.98, respectively. The blend is charged with an initial amount of water from 12 to 30% by weight of the composition. Heating and mixing are terminated after the blend has passed a second peak in viscosity, termination occurring between about 500 and 6,000 centipoise at 35 sec.sup.-1 shear rate at 210.degree.-218.degree. F. The final moisture content of the blend must be between 8.5 to 20% water.
