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 patent discloses a cleansing composition having a fluid composition that includes a cleansing blend comprising a first stearic ester, a second stearic ester, and a branched hydrocarbon, where the first stearic ester and the second stearic ester are different from each other. The fluid composition further includes at least one emulsifier, water, and a humectant, and the cleansing blend components are present in specified weight ratios, including about 2:2:1 or from about 1:1:1.3 to about 1:1:1.5.
In embodiments described in the partial content, the first stearic ester and second stearic ester include stearic ester pairings such as isopropyl isostearate and decyl isostearate, including highly mono-branched decyl isostearate. The branched hydrocarbon is exemplified by isohexadecane, and the fluid composition can be formulated to be silicone-free and to address ocular/skin irritation while providing a soft or cushiony feel and low greasiness.
The partial content describes that the formulation can optionally include a blend of sucrose fatty acid esters and that an emulsifier system can include specific types such as PEG-6 caprylic/capric glycerides and substituted acrylates, with possible use of a thickener such as a Carbomer Interpolymer. The document reports comparative performance and screening outcomes showing that particular stearic ester and branched hydrocarbon combinations improve makeup removal while maintaining skin feel, and that formulation changes can affect removal efficacy, grease, irritation, and other formulation tradeoffs.
Claims Coverage
The partial claims provide four independent claims directed to cleansing compositions with a stearic ester/stearic ester/branched hydrocarbon cleansing blend at defined ratios, cleansing compositions with a defined ratio range, cleansing compositions with specified emulsifier selection, and skin cleansing methods applying the compositions and then rinsing or wiping off. Across these independent claims, the main inventive features revolve around the cleansing blend of two different stearic esters and a branched hydrocarbon at defined weight ratios, together with emulsifier, water, and humectant; additionally, one independent claim specifies the emulsifier selection and another pair includes method steps with the same blend framework.
Dual stearic ester and branched hydrocarbon cleansing blend at about 2:2:1
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, and wherein the first stearic ester, the second stearic ester, and the branched hydrocarbon are present in a weight ratio of about 2:2:1.
Dual stearic ester and branched hydrocarbon cleansing blend within 1:1:1.3 to 1:1:1.5
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, and wherein the first stearic ester, the second stearic ester, and the branched hydrocarbon are present in a weight ratio of from about 1:1:1.3 to about 1:1:1.5.
Selected emulsifier as PEG-6 caprylic/capric glycerides and substituted acrylates
The emulsifier is selected from the group consisting of PEG-6 caprylic/capric glycerides and substituted acrylates.
Applying and rinsing or wiping off a cleansing composition with the 2:2:1 blend
Applying an effective amount of a cleansing composition to a target area of the skin by hand or by use of an applicator, the cleansing composition comprising 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, and wherein the first stearic ester, the second stearic ester, and the branched hydrocarbon are present in a weight ratio of about 2:2:1, and rinsing or wiping off the cleansing composition from the target area of the skin.
Applying and rinsing or wiping off a cleansing composition with the 1:1:1.3 to 1:1:1.5 blend
Applying an effective amount of a cleansing composition to a target area of the skin by hand or by use of an applicator, the cleansing composition comprising 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, and wherein the first stearic ester, the second stearic ester, and the branched hydrocarbon are present in a weight ratio of from about 1:1:1.3 to about 1:1:1.5, and rinsing or wiping off the cleansing composition from the target area of the skin.
Across the independent claims, the coverage focuses on cleansing compositions and skin cleansing methods that use a fluid composition containing a cleansing blend of two different stearic esters and a branched hydrocarbon at defined weight ratios, at least one emulsifier, water, and a humectant. The independent claims further specify either the precise blend ratio or the emulsifier selection, and provide corresponding method steps of applying to a target skin area and then rinsing or wiping off.
Stated Advantages
