The invention discloses bar compositions which are milder than soap but have squeaky feel or rinse associated with soap. This is accomplished by ensuring at least a certain portion (at least 1%), or all, of the soluble surfactant system is ion-sensitive. Further, soluble soap comprises less than 1% by wt. of bar, which helps produce a less alkaline pH bar while allowing squeaky feel to be produced.

Mild, low soluble soap bars which have non-slimy quick rinse perception in use

The invention relates to perfume-containing bar compositions in which the effect of said perfume(s) (e.g., longevity) is enhanced relative to comparative bars in that perfume-containing bar of the invention, comprise less than about 35% soluble surfactant. The invention further comprises a process for enhancing deposition/longevity of perfume, for example, by controlling the level of soluble active relative to insoluble active and/or by increasing levels of perfume.

Compositions and process for preparing cleansing bars comprising low levels of soluble surfactant for enhanced fragrance deposition/longevity

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

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

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

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

Novel chip compositions comprise alkylene glycol, benefit agent and thickening agent (e.g., fumed silica). Use of chips comprising excess of alkylene glycol over benefit agent and thickening agent has been found to allow significant deposition of benefit agent without compromising processing. In a second embodiment, the invention comprises bar compositions comprising mixtures of the chips of the invention and chips containing defined surfactant systems. A process for forming the chips of the invention and a method of enhancing deposition without compromising processing using the chips of the invention are also disclosed.

Bar composition comprising entrapped emollient droplets dispersed therein

Novel chip compositions comprise specifically defined carriers; benefit agent; and thickening agent (e.g., fumed silica). Use of chips comprising excess of these carriers over benefit agent and thickening agent has been found to allow significant deposition of benefit agent without compromising processing. In a second embodiment, the invention comprises bar compositions comprising mixtures of the chips of the invention and chips containing defined surfactant systems. A process for forming the chips of the invention and a method of enhancing deposition without compromising processing using the chips of the invention are also disclosed.

An extruded toilet bar composition comprises mixtures of chips containing polyalkylene glycol, benefit agent and fumed silica, and chips containing a surfactant system.
