These compositions are typically formulated to allow easy application and a pleasing texture. One major drawback with these compositions is the disruption of the composition surface and subsequent used look when pressure is applied to the surface of the composition.
[0001] Cosmetic compositions, are commercially available in various forms, such as creams and mousses, and are well known in the art. These compositions are typically formulated to allow easy application and a pleasing texture. One major drawback with these compositions is the disruption of the composition surface and subsequent used look when pressure is applied to the surface of the composition.
[0002] It is desirable that a composition used as a cosmetic composition, retain a fresh unused look of a n untouched surface. Such a composition would be appealing to the consumer. It has been found that the combination of PEG/PPG emulsifier, diluent, emollient, and water in the present cosmetic composition has an improved texture that retains a fresh unused look.

BRIEF DESCRIPTION OF THE DRAWINGS
[0013] FIG. 1 exemplifies the recovery to the initial configuration of the claimed composition over a period less than 4 hours after application of about 0.5 to about 5 kPa pressure.
DETAILED DESCRIPTION
[0014] The terms used in this specification generally have their ordinary meanings in the art, within the context of the invention, and in the specific context where each term is used. Certain terms are discussed below, or elsewhere in the specification, to provide additional guidance to the practitioner in describing the compounds, compositions, and methods of the invention and how to make and use them.
Moreover, it will be appreciated that the same thing can be said in more than one way.
Consequently, alternative language and synonyms may be used for any one or more of the terms discussed herein, nor is any special significance to be placed upon whether or not a term is elaborated or discussed herein. The use of examples anywhere in this specification, including examples of any terms discussed herein, is illustrative only, and in no way limits the scope and meaning of the invention or of any exemplified term. Likewise, the invention is not limited to the examples presented.
[0015] The present disclosure is directed to a composition comprising an about 7.5% to about 11.0% PEG/PPG emulsifier, an at least one diluent, an at least one emollient, and < 25 weight % water, wherein the composition deviates from an initial configuration after application of about 0.5 to about 5 kPa of pressure on the composition and returns to the initial configuration in less than about 4 hours at room temperature.
[0016] The compositions of the present invention are uniquely formulated to provide not only a stable viscosity over a broad temperature range, but an enhanced feeling of softness and silkiness when the composition is applied to the skin. Moreover, the compositions are capable of easy and uniform application over the skin. These enhanced properties are achieved, in large part, by formulating the compositions with a specific concentration of PEG/PPG emulsifier, an emollient, a diluent, and water in a concentration ratio such that the viscosity remains stable over a broad temperature range.
[0017] The term "stable viscosity", as used herein is meant to define a composition having a viscosity that does not deviate more than about 20% from an initially measured viscosity. Preferably, the stable viscosity does not deviate more than 10%
from an initially measured viscosity. More preferably, the viscosity does not deviate more than 5% from an initially measured viscosity of a composition of the present invention.
[0018] For purposes of this invention the initially measured viscosity is in a range of about 170,000 to about 670,000 CPS. The viscosity measurement was taken at standard temperature and pressure.
[0019] When the phrase "at least one" is used it means one or more different ingredients are used alone or in a combination of ingredients. One of skill in the art would know the limit on how many different ingredients can be used to give the desired effect disclosed herein.
[00201 As used herein, "about" shall generally mean within 20 percent, preferably within 10 percent, and more preferably within 5 percent of a given value or range.
[00211 As used herein, secondary, indicates use of a class of ingredient used once in the composition. A secondary emulsifier is an indication that one emulsifier is already present in the composition.
[0022] The PEG/PPG emulsifier, as used herein, assists in building a matrix in the composition. The PEG/PPG emulsifier is a combination of PEG/PPG and a diluent.
The length of PEG/PPG and the diluent used is determined by the ability of the PEG/PPG/diluent combination that allows recovery of the composition as defined herein. The various PEG/PPG emulsifier combinations utilize a variety of diluents.
PEG/PPG/diluent combinations are found in the Ingredient Database of Personal Care Products Council htto://online.personalcarecouncil.org, and are hereby incorporated by reference.
[0023] The concentration of PEG/PPG emulsifier present in the compositions are found in a concentration of about 7.5% to about 11.0%. This concentration is based on a PEG/PPG 19/19 dimethicone or a PEG/PPG 18/18 dimethicone. The concentration will change depending on the PEG/PPG emulsifier diluent combination used to obtain a composition that recovers as defined herein.
[0024] A suitable emollient for use in the present compositions is a cyclic or straight chain hydrocarbon, and includes, but is not limited to cyclomethicone, <
100cst dimethicone, siloxane, cyclopentasiloxane or any combinations thereof. An emollient provides a softening, protective or soothing effect on the skin surface and is generally considered safe for topical use. It also helps control the rate of evaporation and the tackiness of the compositions.
[0025] The pH of the compositions of the present invention may be adjusted by one or more pH adjusters and/or chelating agents. For example, sodium hydroxide, triethanolamine, EDTA salt, or any combinations thereof, are suitable pH

[0041] It is, of course, understood that the present cosmetic composition may further include optional ingredients generally known by one skilled the art to be suitable for use in a cosmetic composition. Lists of carriers and optional ingredients, which are well known in the art, are disclosed, for example, in "Cosmetics: Science and Technology," edited by M. S. Balsam and E. Sagarin, 2nd Edition, 1972, Wiley Pub.
Co.; "The Chemistry and Manufacture of Cosmetics" by M. G. DeNavasse; and "Harry's Cosmeticology," J. B. Wilkinson et al., 7th Edition, 1982, Chem. Pub.
Co.; the disclosures of each of the above being incorporated herein by reference.
[0042] The composition may be in a variety of forms of make-up composition applied to keratinous surfaces for the purpose of coloring, conditioning, or otherwise beautifying the keratinous surface. Make-up is also known as color cosmetics and includes products such as eye shadow, blush, concealer, lipstick, lip gloss, or eyeliner compositions in a solid, or stick form.
[0043] The examples below illustrate exemplary formulations of the cosmetic composition. They are not intended as a limitation upon the scope of the present application.
Example 1 [0044] Compositions tested contained PEG/PPG emulsifier, diluent, emollient, and water.
[0045] The variation of configuration from an initial configuration having a bin width of about 0.15 to a deviation from the initial configuration to a bin width of about 0.9 after application of about 0,5 kPa to about 5 kPa of pressure to the composition is depicted in Figure 1.
[0046] Bin width is a measure of pixel light intensity variation (Lmax and Lmin). Lmax represents light intensity value for the lightest pixel in a photograph. Lin represents the light intensity value for the darkest pixel in a photograph. For 8-bit images, the light intensity values can vary from 0 to 255. The bin width for the image would be maximum lightness variation (Lmax Lmin) divided by number of bins (256 for an 8-bit gray scale image) according to the following equation:
¨
Bin = __ Lt1u7x Lr \Number of B ins) graY scaTff 256 [0047] The experiment was repeated with samples having various concentration ranges of PEG/PPG emulsifier, diluent, emollient, and water with a range in pressure from about 0.5 to about 5 KPa. The initial bin width was 0.05 to about 0.15 range.
The disturbed surface bin width was 0.8 to 1.0 range. Compositions returned to the initial bin width (configuration) within 2 to 4 hours resting undisturbed. The bin width for the image would be maximum lightness variation ([max - Lmin) divided by number of bins (256 for a 8-bit gray scale image) according to the above equation.
[00481 In an example a composition in an initial configuration was exposed to a defused light source. An image was taken of the composition at a forty-five degree angle to the surface of the composition. The surface of the composition was disturbed by application of about 0.5 to about 5 kPa of pressure with the finger or any instrument or applicator. Without change in the light source, the composition position, or camera position, an image was taken of the surface of the composition that deviates from the initial configuration (reference image). The composition was allowed to sit undisturbed and images were taken every fifteen minutes until the composition returned to the initial configuration. The time it took to return to the initial configuration after application of pressure to the surface was about 4 hours. The change in surface was measured by subtracting the reference image from the image taken at any given time. The images were converted into an 8-bit gray scale image using http://rsbweb.nih.qov/ii/ software. The disturbed areas caused by the finger (or applicator) in each subtraction image were individually analyzed using Image J
software (http://rsbweb.nih.qov/ij/) and bin width values were measured. The initial configuration had a bin width of 0.15. The disturbed surface (surface that deviates from an initial configuration) had a bin width of 0.9. After four hours the composition returned to a bin width value of 0.15.
1100491 The amount of average pressure exerted on a cosmetic composition while touching it with a finger (application of pressure), was measured as follows:
a. The cosmetic composition was placed on a scale. A volunteer touched the composition surface lightly with an index finger.
b. The surface area of contact by the finger was calculated using the Image J
software (http://rsbweb.nih.qov/iii). The distances for the measurements were calibrated by a ruler in the picture.
c. The force (a) / surface area (b) = pressure.
d. The aforementioned procedure was repeated at least 5 times for each person and in total 6 people participated in this part of study. The pressure values ranged from 0.6 to 4.8 KPa.

BRIEF DESCRIPTION OF THE DRAWINGS
[0013] FIG. 1 exemplifies the recovery to the initial configuration of the claimed composition over a period less than 4 hours after application of about 0.5 to about 5 kPa pressure.
DETAILED DESCRIPTION
[0014] The terms used in this specification generally have their ordinary meanings in the art, within the context of the invention, and in the specific context where each term is used. Certain terms are discussed below, or elsewhere in the specification, to provide additional guidance to the practitioner in describing the compounds, compositions, and methods of the invention and how to make and use them.
Moreover, it will be appreciated that the same thing can be said in more than one way.
Consequently, alternative language and synonyms may be used for any one or more of the terms discussed herein, nor is any special significance to be placed upon whether or not a term is elaborated or discussed herein. The use of examples anywhere in this specification, including examples of any terms discussed herein, is illustrative only, and in no way limits the scope and meaning of the invention or of any exemplified term. Likewise, the invention is not limited to the examples presented.
[0015] The present disclosure is directed to a composition comprising an about 7.5% to about 11.0% PEG/PPG emulsifier, an at least one diluent, an at least one emollient, and < 25 weight % water, wherein the composition deviates from an initial configuration after application of about 0.5 to about 5 kPa of pressure on the composition and returns to the initial configuration in less than about 4 hours at room temperature.
[0016] The compositions of the present invention are uniquely formulated to provide not only a stable viscosity over a broad temperature range, but an enhanced feeling of softness and silkiness when the composition is applied to the skin. Moreover, the compositions are capable of easy and uniform application over the skin. These enhanced properties are achieved, in large part, by formulating the compositions with a specific concentration of PEG/PPG emulsifier, an emollient, a diluent, and water in a concentration ratio such that the viscosity remains stable over a broad temperature range.
[0017] The term "stable viscosity", as used herein is meant to define a composition having a viscosity that does not deviate more than about 20% from an initially measured viscosity. Preferably, the stable viscosity does not deviate more than 10%
from an initially measured viscosity. More preferably, the viscosity does not deviate more than 5% from an initially measured viscosity of a composition of the present invention.
[0018] For purposes of this invention the initially measured viscosity is in a range of about 170,000 to about 670,000 CPS. The viscosity measurement was taken at standard temperature and pressure.
[0019] When the phrase "at least one" is used it means one or more different ingredients are used alone or in a combination of ingredients. One of skill in the art would know the limit on how many different ingredients can be used to give the desired effect disclosed herein.
[00201 As used herein, "about" shall generally mean within 20 percent, preferably within 10 percent, and more preferably within 5 percent of a given value or range.
[00211 As used herein, secondary, indicates use of a class of ingredient used once in the composition. A secondary emulsifier is an indication that one emulsifier is already present in the composition.
[0022] The PEG/PPG emulsifier, as used herein, assists in building a matrix in the composition. The PEG/PPG emulsifier is a combination of PEG/PPG and a diluent.
The length of PEG/PPG and the diluent used is determined by the ability of the PEG/PPG/diluent combination that allows recovery of the composition as defined herein. The various PEG/PPG emulsifier combinations utilize a variety of diluents.
PEG/PPG/diluent combinations are found in the Ingredient Database of Personal Care Products Council htto://online.personalcarecouncil.org, and are hereby incorporated by reference.
[0023] The concentration of PEG/PPG emulsifier present in the compositions are found in a concentration of about 7.5% to about 11.0%. This concentration is based on a PEG/PPG 19/19 dimethicone or a PEG/PPG 18/18 dimethicone. The concentration will change depending on the PEG/PPG emulsifier diluent combination used to obtain a composition that recovers as defined herein.
[0024] A suitable emollient for use in the present compositions is a cyclic or straight chain hydrocarbon, and includes, but is not limited to cyclomethicone, <
100cst dimethicone, siloxane, cyclopentasiloxane or any combinations thereof. An emollient provides a softening, protective or soothing effect on the skin surface and is generally considered safe for topical use. It also helps control the rate of evaporation and the tackiness of the compositions.
[0025] The pH of the compositions of the present invention may be adjusted by one or more pH adjusters and/or chelating agents. For example, sodium hydroxide, triethanolamine, EDTA salt, or any combinations thereof, are suitable pH
adjusters/chelating agents that may be included in the compositions of the present invention.

[0041] It is, of course, understood that the present cosmetic composition may further include optional ingredients generally known by one skilled the art to be suitable for use in a cosmetic composition. Lists of carriers and optional ingredients, which are well known in the art, are disclosed, for example, in "Cosmetics: Science and Technology," edited by M. S. Balsam and E. Sagarin, 2nd Edition, 1972, Wiley Pub.
Co.; "The Chemistry and Manufacture of Cosmetics" by M. G. DeNavasse; and "Harry's Cosmeticology," J. B. Wilkinson et al., 7th Edition, 1982, Chem. Pub.
Co.; the disclosures of each of the above being incorporated herein by reference.
[0042] The composition may be in a variety of forms of make-up composition applied to keratinous surfaces for the purpose of coloring, conditioning, or otherwise beautifying the keratinous surface. Make-up is also known as color cosmetics and includes products such as eye shadow, blush, concealer, lipstick, lip gloss, or eyeliner compositions in a solid, or stick form.
[0043] The examples below illustrate exemplary formulations of the cosmetic composition. They are not intended as a limitation upon the scope of the present application.
Example 1 [0044] Compositions tested contained PEG/PPG emulsifier, diluent, emollient, and water.
[0045] The variation of configuration from an initial configuration having a bin width of about 0.15 to a deviation from the initial configuration to a bin width of about 0.9 after application of about 0,5 kPa to about 5 kPa of pressure to the composition is depicted in Figure 1.
[0046] Bin width is a measure of pixel light intensity variation (Lmax and Lmin). Lmax represents light intensity value for the lightest pixel in a photograph. Lin represents the light intensity value for the darkest pixel in a photograph. For 8-bit images, the light intensity values can vary from 0 to 255. The bin width for the image would be maximum lightness variation (Lmax Lmin) divided by number of bins (256 for an 8-bit gray scale image) according to the following equation:
¨
Bin = __ Lt1u7x Lr \Number of B ins) graY scaTff 256 [0047] The experiment was repeated with samples having various concentration ranges of PEG/PPG emulsifier, diluent, emollient, and water with a range in pressure from about 0.5 to about 5 KPa. The initial bin width was 0.05 to about 0.15 range.
The disturbed surface bin width was 0.8 to 1.0 range. Compositions returned to the initial bin width (configuration) within 2 to 4 hours resting undisturbed. The bin width for the image would be maximum lightness variation ([max - Lmin) divided by number of bins (256 for a 8-bit gray scale image) according to the above equation.
[00481 In an example a composition in an initial configuration was exposed to a defused light source. An image was taken of the composition at a forty-five degree angle to the surface of the composition. The surface of the composition was disturbed by application of about 0.5 to about 5 kPa of pressure with the finger or any instrument or applicator. Without change in the light source, the composition position, or camera position, an image was taken of the surface of the composition that deviates from the initial configuration (reference image). The composition was allowed to sit undisturbed and images were taken every fifteen minutes until the composition returned to the initial configuration. The time it took to return to the initial configuration after application of pressure to the surface was about 4 hours. The change in surface was measured by subtracting the reference image from the image taken at any given time. The images were converted into an 8-bit gray scale image using http://rsbweb.nih.qov/ii/ software. The disturbed areas caused by the finger (or applicator) in each subtraction image were individually analyzed using Image J
software (http://rsbweb.nih.qov/ij/) and bin width values were measured. The initial configuration had a bin width of 0.15. The disturbed surface (surface that deviates from an initial configuration) had a bin width of 0.9. After four hours the composition returned to a bin width value of 0.15.
1100491 The amount of average pressure exerted on a cosmetic composition while touching it with a finger (application of pressure), was measured as follows:
a. The cosmetic composition was placed on a scale. A volunteer touched the composition surface lightly with an index finger.
b. The surface area of contact by the finger was calculated using the Image J
software (http://rsbweb.nih.qov/iii). The distances for the measurements were calibrated by a ruler in the picture.
c. The force (a) / surface area (b) = pressure.
d. The aforementioned procedure was repeated at least 5 times for each person and in total 6 people participated in this part of study. The pressure values ranged from 0.6 to 4.8 KPa.
