The present invention relates to compositions comprising a structured benefit agent pre-mix or delivery vehicle comprising benefit agent structured with crystalline materials, as defined, which when separately prepared and combined after preparation, provides enhanced deposition of hydrophilic benefit agents carried on, trapped within or in the presence of the structured benefit agent.

Personal product compositions comprising structured benefit agent premix or delivery vehicle and providing enhanced deposition of hydrophilic benefit agent

The present invention relates to a multiphase cleansing bar having a plurality of phases of cleansing material. Adjacent phases preferably have different concentration levels of benefit components respectively and all the phases individually preferably have a substantially similar cleansing base consisting of a syndet base, a soap base, or mixtures thereof. These benefit components are emollients, moisturizers, nutrients, anti-aging materials etc. Segregation of the benefit rich component is expected to result in improved deposition of the benefit components on the skin during the product application, which improves the moisture barrier properties of the skin. Chemical and Theological compatibility between the phases is maximized and recycling of the product during production is facilitated with the use of a uniform cleansing base. Methods of producing the inventive bar by extruding and melt casting are also disclosed.

Personal washing bar having adjacent emollient rich and emollient poor phases

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 bar compositions in which an emollient composition comprising thickened entrapped emollient is added to a base bar composition at or during time of extrusion to form macroscopic, concentrated domains of emollient droplets. Addition of entrapped droplets allows far greater deposition than if the non-trapped emollients had been mixed in directly to form chips which are then extruded to form final bar.

Personal washing bar compositions comprising emollient rich phase/stripe

A bar composition in which use of specific ratio of cationic to surfactant as been found to remarkably enhance deposition of oil/emollient benefit agent.

Bars comprising benefit agent and cationic polymer

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.

System comprising synthetic detergent bar and pouf for holding bar

Novel compositions are prepared in a non-molten process. In particular, compositions comprise optional fillers with both soap and high levels of synthetic surfactants. When high levels of soap and surfactant are normally used in such process, there is a significant 'grittiness' problem. Pre-processing the surfactant containing chip (e.g., 'DEFI' chip) has been unexpectedly found to remedy this problem.

Non-molten-mix process for making bar comprising acyl isethionate based

Adjuvant powder compositions contain a benefit agent or benefit agents and enhance the delivery of these benefit agent or agents when used as a separate adjuvant during preparation of bar compositions. Carriers used in the formation of the adjuvants must have a melting point high enough to survive a spray-drying process.

Bar compositions comprising adjuvant powders for delivering benefit agent

The present invention relates to cast melt bar composition comprising surfactant, fatty acid, generally lower MW polyalkylene glycol and small amounts of water wherein the ratio of total polyol to water is at least 3:1. By using less water and greater variants of polyol, the bars allow larger amounts of generally insoluble materials to be used and also allow retention of bar integrity using limited amounts of soap (important for mildness).

Pourable cast melt bar compositions comprising low levels of water and

The present invention relates to personal wash bar compositions comprising hydrophobic, low viscosity (less than 1000 cp) emollient agents which have been specifically pre-thickened with defined polymer composition. Use of the specific thickeners allow incorporation of the low viscosity oil (viscosity less than 1000 cp) in the personal wash compositions to deliver enhanced skin benefits and desired user properties without compromising foaming and bar processing.

Bar composition comprising low viscosity oils pre-thickened by

A process for making bars having enhanced deposition of benefit agent wherein the process comprises mixing adjuvant powder compositions which contain a benefit agent or agents and surfactant-containing 'base' or regular chips; plodding and extruding to form final bar.

Process for making bar compositions having enhanced deposition of

The present invention relates to synthetic detergent bars comprising 10-60% by wt. synthetic detergent surfactant; 10-60% of a water soluble structuring of water soluble structurant of MP between 40.degree. to 100.degree. C.; and 5-50% by wt. of a water-insoluble structurant of MP between 4.degree.--100.degree. C. Unexpectedly, applicants have found that addition of 'true' water soluble starches yields processing and composition advantages.

Detergent bars comprising water soluble starches

The present invention is directed to novel compounds having the formula: ##STR1## wherein R is a C.sub.8 -C.sub.24 substituted or unsubstituted alkyl or alkenyl group;

Isethionate esters of alkyl alkoxy carboxylic acid

The present invention relates to toilet bar compositions comprising aldobionamides and an amount of polyalkylene glycol sufficient to structure the bar. Unexpectedly it has been found that this polyalkylene glycol structures the bar without simultaneously inhibiting lather formation.
