Abstract
A cleansing composition and method of using a cleansing composition, the cleansing composition including a blend of three different emollients, the emollients including a first stearic ester, a second stearic ester, and a branched hydrocarbon, where the first stearic ester and second stearic ester are different from each other.
Core Innovation
The invention relates to a cleansing composition comprising a fluid composition embedded into a substrate, wherein the substrate comprises a nonwoven wipe. The fluid composition includes a cleansing blend of a first stearic ester, a second stearic ester, and a branched hydrocarbon, with the first stearic ester and second stearic ester being different from each other. The fluid composition further comprises a blend of sucrose fatty acid esters, water, and a thickener.
The first stearic ester is present in an amount of from about 1.0% to about 3.0% by weight of the fluid composition, the second stearic ester is present in an amount of from about 1.0% to about 3.0% by weight of the fluid composition, and the branched hydrocarbon is present in an amount of from about 0.5% to about 1.5% by weight of the fluid composition. The patent describes selecting and combining these components within the embedded wipe fluid system.
The disclosed compositions are described in the context of improved cleansing for facial makeup removal, including removal of foundation, eyeliner, and mascara. The patent also provides documentation of testing and ranking of removal performance using in vitro and in vivo panel rankings and formulation/ingredient evaluation approaches to identify a preferred emollient system.
Claims Coverage
The partial content provides two independent claims. Across these claims, there are four main inventive elements: an embedded fluid in a nonwoven wipe substrate, a cleansing blend of two different stearic esters plus a branched hydrocarbon, a blend of sucrose fatty acid esters with water and a thickener, and specified weight ranges for the stearic esters and branched hydrocarbon.
Embedded fluid composition in a nonwoven wipe substrate
A cleansing composition comprising a fluid composition embedded into a substrate, wherein the substrate comprises a nonwoven wipe.
Cleansing blend with first and second stearic esters and a branched hydrocarbon
A cleansing blend comprising a first stearic ester, a second stearic ester, and a branched hydrocarbon, wherein the first stearic ester and second stearic ester are different from each other.
Sucrose fatty acid ester blend with water and a thickener
A blend of sucrose fatty acid esters, water, and a thickener.
Specified weight ranges for stearic esters and branched hydrocarbon
The first stearic ester is present in an amount of from about 1.0% to about 3.0% by weight of the fluid composition, the second stearic ester is present in an amount of from about 1.0% to about 3.0% by weight of the fluid composition, and the branched hydrocarbon is present in an amount of from about 0.5% to about 1.5% by weight of the fluid composition.
Rubbing the skin with the nonwoven wipe to remove cosmetic product
Contacting the surface of the skin with a cleansing composition comprising a fluid composition embedded into a substrate, wherein the substrate comprises a nonwoven wipe; and rubbing the surface of the skin with the substrate to remove the cosmetic product from the surface of the skin.
The independent claims cover both a specific cleansing composition structure and a method that uses contact and rubbing to remove a cosmetic product from skin. The core limitations include specified weight ranges for the first stearic ester, second stearic ester, and branched hydrocarbon, and the stearic esters are required to be different from each other.
Stated Advantages
Low ocular/skin irritation.
Reduced greasiness/residue.
Cushioned feel.
Silicone-free or substantially free formulations.
Documented Applications
Removal of facial makeup products from skin, including foundation, eyeliner, and mascara, using the nonwoven wipe embedded cleansing composition and rubbing.
Testing and ranking of cosmetic product removal performance using in vitro and in vivo panel rankings and formulation/ingredient evaluation approaches [procedural detail omitted for safety].
