This invention relates to rinse-off skin conditioning compositions comprising relatively low amounts of oil/emollient and relatively low amounts of aqueous phase stabilizer/structurant. Use of unsaturated fatty acid (or at least minimum amount of unsaturated fatty acid as percentage of total fatty acid) has been found to result in unexpectedly high hydration. In a second embodiment, use of branched fatty acid (at minimum amount branched as percentage of total) also results in superior hydration. Also mixtures of unsaturated and branched fatty acids can be used. In a second embodiment, the invention relates to method of enhancing hydration using compositions as noted.

In-shower lotion compositions comprising up to 10% free fatty acids wherein ratio of unsaturated to saturated fatty acids is at least 1:1

A mild, substantially isotropic skin cleansing solution was found to be able to suspend insoluble components and provide copious amounts of lather. The cleanser is formulated with synthetic anionic surfactants and a specific ratio of carboxylic acid(s) to hydrophobically modified cross-linked acrylate copolymer(s). The carboxylic acid and acrylate polymer combination were found to provide a synergistic effect on zero shear viscosity at 25 C in a specific pH and copolymer/acid concentration ratio range.

Liquid personal cleansing composition

The invention relates to substantially surfactant free gel compositions comprising hydrophobic and hydrophilic benefit agents. Unexpectedly, the applicants have found these agents deposit with greater substantivity from such liquid gel compositions relative to surfactant-containing lotion.

Substantially surfactant free in-shower gel compositions comprising hydrophilic and hydrophobic benefit agents

An ordered liquid crystalline phase cleansing composition is disclosed that is mild to the skin, contains entrained air and is characterized by excellent sensory and skin feel properties, flow properties and stability.

Ordered liquid crystalline cleansing composition with suspended air

The present invention relates to substantially surfactant-free liquid compositions comprising moderate levels of oil. By limiting amount of oil and using aqueous phase structuring agent, it is possible to provide stable and optionally translucent compositions.

Stable, substantially surfactant-free liquid compositions comprising hydrophobic phase

The invention relates to wet skin treatment compositions having specific gum and acrylate dispersion stabilizer systems providing enhanced rheology (e.g., lotion-like rheology and spreadability) relative to other wet skin compositions.

Wet-skin treatment compositions using specific gum and acrylate systems for enhanced rheology

An ordered liquid crystalline phase cleansing composition is disclosed that contains a solid particulate optical modifier that modifies the appearance of the skin after rinsing the skin. A method of depositing the solid particulate optical modifier to the skin or hair with the ordered liquid crystalline phase cleansing composition is also disclosed.

Ordered liquid crystalline cleansing composition with particulate optical modifiers

The invention provides high molecular weight polymers used in small amounts as viscosity modifiers for aqueous/aqueous biphasic liquids. The viscosity of the biphasic is enhanced at least 20%, preferably at least 30% relative to same compositions without use of polymer. Further, the polymer is included without destroying the ability of dual phase compositions to form after product is left standing.

Low amounts of high molecular weight polymers for enhancing viscosity of aqueous/aqueous biphasic liquids

An aqueous isotropic liquid cleansing and moisturizing composition is provided having a surfactant; a thickening agent, and a solid particulate optical modifier that modifies the appearance of the skin after wash off.

Isotropic cleansing composition with particulate optical modifiers

The invention relates to use of polydextrose in combination with sucrose to induce biphasic liquid formation. Salt may be optionally used.

Biphasic composition induced by polydextrose and sucrose

A foaming cleansing product is provided as a cleansing composition packaged in a non-aerosol pump dispenser. The dispenser includes a container for holding a liquid composition, a dispensing head with a housing enclosing a pump mechanism and a screen material in the flow path to convert liquid composition into a foam. The cleansing composition comprises an anionic surfactant, and at least one surfactant selected from a nonionic and an amphoteric surfactant, a cationic polymer, and a hydrophobic antibacterial agent, and contains less than 0.05 wt. % of a water insoluble emollient; said composition being dispensed by the pump dispenser to provide a foam. The total amount of surfactants in the inventive composition does not exceed 12 wt. %, and preferably does not exceed 10.5 wt. %.

The invention relates to a plurality of liquid cleansing compositions having at least one lamellar phase which possesses a lotion-like appearance conveying signals of enhanced moisturization and at least one abutting isotropic phase having enhanced cleansing ability. The inventive composition is contained in a partitionless container in one embodiment conveying signals of a plurality of compositions. This multiphase composition is stable upon storage and is dispensed as a striped product where typically one stripe has primarily a cleansing function and a second stripe has primarily a moisturization function.

Extrudable multiphase composition comprising a lamellar phase and an isotropic phase

A shower gel formulation having a clear appearance is described which suspends insoluble particles, water insoluble liquids or bubbles and contains an acrylate copolymer, an anionic surfactant, a cationic polymer and, optionally, an amphoteric surfactant. The method of use of the clear shower gel is also described.
