A mild toilet bar composition contains C8-C18 mono and diacyl isethionates in a specified ratio in a first preferred embodiment of the invention and a specified ratio of calcium and magnesium diacyl isethionates in a second preferred embodiment of the invention. Both toilet bars provide substantial lather, mild cleansing, low mush and wear rate levels during use.

Mild acyl isethionate toilet bar composition

A test method is described for comparing the relative affinity of products for a target substance using a substrate ordinarily and visibly sensitive to the products. The test method is useful in one embodiment for comparing the ability of harsh cleansers to remove fatty acids from the skin with mild cleansers that do not remove fatty acids to the same extent using a visually compelling substrate, such as a fresh cut flower.

Test method

Toilet bar compositions are described that contain specific odor masking agent(s). The odor masking agent(s) reduce malodor without the need for elevated amounts of masking fragrances that individuals may not prefer and who use the composition for personal cleansing or who are exposed to the composition.

Reduced odor toilet bar composition

Liquid lamellar cleansing compositions are described that contain synthetic surfactants, hydrophilic emollients and exfoliant particles where 80% or more of the particles have a major axis length of between 100 and 1000 microns. The combination of the mild surfactants, moisturizers, and exfoliants provide the user with simultaneous moisturization and exfoliation in a convenient liquid cleansing product.

Liquid cleansing composition having simultaneous exfoliating and moisturizing properties

The invention relates to a process for making single phase dilution thickening compositions comprising electrolyte. By adding defined associative thickener to said compositions applicants have found one can lower level of salt/electrolyte required to obtain dilution thickening effect.

Process for lowering level of salt required for dilution thickening

The invention relates to use of specifically defined polydextrose to induce biphasic liquid formation. Optional use of salt allows less polydextrose to be used to induce biphasic formation.

Biphasic composition induced by polydextrose

Composition may be prepared in a single DEFI reactor comprising mixtures of (1) DEFI (directly esterified fatty acyl isethionate) and (2) a compound produced by the reaction of (a) isethionate with a fatty acid replacement (e.g., a multicarboxylic fatty acid, a fatty acid); or (b) fatty acid with an isethionate replacement (e.g., C -C alcohols, C -C organic acids, amines). Such mixtures are milder than DEFI alone while retaining substantially same foaming benefit.

Compositions comprising combination of DEFI and modified DEFI and methods of making

The present invention relates to the composition comprising soap and alkoxylated triglyceride wherein said bars have improved sensory properties (e.g., reduced drag and stickiness; and enhanced slipperiness) relative to identical bar with non-alkoxylated triglyceride.

Soap bar comprising high levels of specific alkoxylated triglycerides which provide enhanced sensory properties and process well

The invention relates to soap bars comprising 6% to 13% triglyceride oils wherein said bars simultaneously have post processing properties and maintain good lather. In a second embodiment, the invention relates to a process of making predominantly soap bars having noted properties comprising adding 6 to about 13% by wt. triglyceride oil(s) at finishing stage post crystallization.

Soap bar comprising about 6% and greater triglycerides which structure well and have desirable user properties

The invention provides a single chamber transparent or translucent package and personal product composition where when standing, the product forms 2 or more visibly distinct phases and, when agitated, the composition forms a visible single phase.

Separating multi-phase personal wash composition in a transparent or translucent package

Process for making soap bar comprising about 6% and greater triglycerides

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

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

The present invention relates to skin cleansing bar composition in which polyalkylene glycols of very specific molecular weights are used to define compositions which are mild, foam well and provide consumer-desired sensory profiles. A significant amount of these specific PEGs must be incorporated into the bar to deliver these desired effects. To properly process such a bar composition, the cast-melt method is the preferred technique.

Cast melt bar compositions comprising high levels of low molecular

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
