Description

COSMETIC COMPOSITION THAT RESISTS PILLING

REFERENCE TO RELATED APPLICATIONS AND PRIORITY

This application claims the benefit of, and priority to, US Patent Application No. 17/387,982 filed on July 28, 2021, and French Application No. FR2111499 filed on October 28, 2021, the entireties of which are incorporated herein by reference.

FIELD OF THE INVENTION

The present invention is generally directed to a pilling-resistant cosmetic composition and method for manufacturing the same for providing benefits to the skin of a user, the pilling-resistant cosmetic composition including a high amount of actives for conferring benefits to the user’s skin and having a favorable textural aesthetic that is resistant to pilling that is associated with use of polymeric thickeners and other ingredients that stabilize and lend aesthetic benefits to the pilling-resistant cosmetic composition. Benefits of the pilling-resistant cosmetic composition may include, but are not limited to, generally moisturizing skin, or enhancing skin, for example, by improving skin smoothness and radiance, minimizing pore appearance, reducing the appearance fine lines and wrinkles, brightening skin, treating acne, or reducing the effects of acne, and reducing one or more of dryness, tightness, dark spots, redness, and inflammatory lesions, or a combination of any of these.

BACKGROUND OF THE INVENTION

There are a variety of skin conditions that benefit from leave-on cosmetic compositions that may be applied on the skin for any of a variety of possible benefits. In some examples, it is challenging to formulate skin care cosmetics that include sufficiently high amounts of actives to confer desired benefits. Products that include high amounts of actives are often formulated with a high content of oils, emulsifiers and/or thickeners to facilitate dispersion and/or solubilization of the actives. Such formulations can be heavy and leave a greasy skin feel or cause dryness or irritation, and those that include stabilizing thickeners are vulnerable to pilling. More generally, skin care compositions in emulsion forms with about forty percent or more water phase that include polymeric thickeners can also be vulnerable to pilling on application. Such pilling can affect the availability of the actives for maximum benefit to the skin, and pilling is particularly problematic for leave on formulations.

Accordingly, there is a need in the art for a cosmetic composition that offers light weight feel in a stable formulation that resists pilling typically associated with thickener stabilized compositions.

This disclosure describes exemplary embodiments in accordance with the general inventive concepts and is not intended to limit the scope of the invention in any way. Indeed, the invention as described in the specification is broader than and unlimited by the exemplary embodiments set forth herein, and the terms used herein have their full ordinary meaning.

DETAILED DESCRIPTION OF THE INVENTION

In the context of the invention, a direct emulsion is an oil in water emulsion.

As used herein, the term “pilling” refers to failure of some or all of a composition to soak in when applied to a keratinous substrate, including facial and body skin, lips, hair, and nails, forming small globules, strands or particles that collect on the surface, and exhibit an inability to be spread as a uniform emulsion. Instability can occur in compositions made outside of the scope of the disclosure (i.e., compositions lacking the disclosed polymer and ethoxylated agents), and compositions including amounts of polymeric thickener in excess of the amounts according to the disclosure. Likewise, other instability issues of a composition outside of the scope of the disclosure (i.e., compositions lacking the disclosed polymer and ethoxylated agents) include separation of phases; watery texture; gellification of the cosmetic composition.

The terms “Exclude,” “Free” and “Essentially Free” means that no reliably measurable excluded material, for example, an excluded gellan and other gellifying agents, waxes, plant butters greater than about 5%, by weight, based on the total weight of the pilling-resistant cosmetic composition, and saturated fatty alcohols/acids above C16 present in amounts greater than about 5%, by weight, based on the total weight of the pilling-resistant cosmetic composition, or other excluded material as described herein, is present in the pilling-resistant cosmetic composition. The term “essentially free” means that, while it is preferred that no excluded material is present in the pilling-resistant cosmetic composition, it is possible to have very small amounts of the excluded material in the pilling-resistant cosmetic composition of the invention, provided that these amounts do not materially affect the advantageous properties of the pilling-resistant cosmetic composition. In particular, “essentially free” means that excluded material can be present in the pilling-resistant cosmetic composition at an amount of less than 5%, or less than 4%, or less than 3%, or less than 2%, or less than 1%, or less than 0.1% by weight, based on the total weight of the pilling-resistant cosmetic composition.

As shown herein, the inventors have provided the pilling-resistant cosmetic composition in the form of a direct oil in water emulsion that includes water and oily phases and includes at least one cosmetically acceptable polymeric thickener selected from the group consisting of crosspolymers, gums, taurate based polymers, carbomers, polyacrylates, and combinations thereof, at least one ethoxylated agent in liquid form at ambient temperature in a range from about 20 ˚C to about 28 ˚C and has an HLB from about 8.5 to about 16; and at least one oil. The pilling-resistant cosmetic composition resists pilling when applied by rubbing or smoothing on a keratinous substrate.

The pilling-resistant cosmetic composition may also include one or more additional ingredients selected from, but not limited to, phenylethyl resorcinol, chelating agents, other skin active components, antimicrobials and preservatives, fillers, antioxidants, fragrances, pearlescent agents, odor absorbers, coloring materials, essential oils, vitamins, and combinations of these.

A key problem in cosmetic compositions that include polymeric emulsifiers and thickeners is pilling resulting in the inability of a composition to be spread as a uniform emulsion resulting in failure of some or all of the applied composition to soak into skin. Pilling represents the formation of small globules or particles that collect on the skin's surface when the composition is spread on to a substrate, such as skin. Pilling is visually and aesthetically unpleasant and also adversely affects the effectiveness of the composition. Pilling is often associated with the presence of relatively high amounts of thickeners/thickening emulsifiers which are useful for stabilizing high amounts of skin actives. Although thickeners/thickening emulsifiers can be effective at stabilizing emulsions, the potential of pilling is high, even at modest usage levels of these ingredients. Moreover, for certain formulas, especially those with any electrolytes or ionic components, a higher level of polymer is required to afford stability increasing the risk of pilling. Pilling is an unacceptable trait for products, as consumers do not want their product to slough off of their skin; this issue becomes more pronounced as consumers layer more and more skin care and makeup products on their face.

The inventors sought to develop a solution for reducing pilling potential associated with a wide variety of polymeric thickeners. The inventors have surprisingly found that ethoxylated fatty alcohols and ethoxylated fatty acids represent a class of raw materials (herein referred to as “ethoxylated agents”) that can significantly reduce pilling potential of multiple classes of polymeric thickeners/thickening emulsifiers that are used in a wide range of oil-in-water emulsions. In the general cosmetic arts, ethoxylated fatty alcohols and ethoxylated fatty acids are known as emulsifiers or as solubilizers and are characterized by the presence of a hydrophobic alky fatty alcohol/acid portion and a hydrophilic ethylene oxide portion.

In preparing the inventive pilling-resistant cosmetic composition, several liquid emulsifiers/solubilizers of intermediate HLB (from about 8-to about 16) were tested as additives to simplex formulas containing polymeric thickeners present in amounts that are known to result in pilling of the simplex formulas. Without being bound by theory, it is believed that an intermediate HLB emulsifiers (vs. an oil, for example) would interact with the water and oily emulsion components of the pilling-resistant cosmetic composition at the hydrophobic/hydrophilic interface and not at only one of the hydrophobic or hydrophilic portions of the agent. Lower HLB emulsifiers were not tested, as they are known in the art to make inverse emulsions and could disrupt and or destabilize direct emulsions. Ethoxylated agents selected from ethoxylated fatty alcohols and ethoxylated fatty acids were employed according to the disclosure and were shown to reduce or eliminate pilling in the simplex formulas that were otherwise known to pill. These test formulas did not result in inverse emulsions and/or destabilized direct emulsions. Specific examples of these ethoxylated agents, as shown in the examples, include laureth-4, oleth-10.

As shown, in some embodiments, the pilling-resistant cosmetic composition may optionally include one or more glyceryl containing ingredients, for example, but not limited to, polyglyceryl-6 dicaprate, and PEG-7 glyceryl cocoate, which may be advantageously used for enhancing permeability of actives, among other possible benefits.

Thus, the inventors have shown that ethoxylated agents employed as described and exemplified herein surprisingly demonstrate a marked effect of reducing pilling that has been a vexing problem in the art for a wide range of emulsion architectures that include a wide variety of polymeric thickeners. There is no evidence in the current art of any association of ethoxylated agents with the elimination and/or reduction of pilling associated with polymeric thickeners/thickening emulsifiers. The inventors have shown herein that a direct emulsion cosmetic composition that has potential to pill on the skin (caused by polymeric thickeners/thickening emulsifiers) can be improved by reduction or elimination of pilling upon inclusion of ethoxylated agents as disclosed herein.

In accordance with the various embodiments, it is contemplated that some or all of following ingredients would be excluded from the pilling-resistant cosmetic compositions used according to the invention: gellan and other gellifying agents, waxes, plant butters greater than about 5%, by weight, based on the total weight of the pilling-resistant cosmetic composition, and saturated fatty alcohols/acids above C16 present in amounts greater than about 5%, by weight, based on the total weight of the pilling-resistant cosmetic composition.

TABLE 5 shows the in vitro pilling test results with each of the test formulas. NP = no pilling, MP = minimal pilling and SP= significant pilling.

As shown in TABLE 5, each of laureth-4 and oleth-10 prevented pilling in with all eight tested polymeric thickeners. The formulations including only amphiphilic liquid RM with HLB 8.5-16 (i.e., without any ethoxylated agent) did not fully eliminate pilling when used with two of the eight polymeric thickeners, and likewise, the PEG glyceryl cocoate amphiphilic liquid RM with HLB 8.5-16 (i.e., without any ethoxylated agent) did not fully eliminate pilling when used with three of the eight polymeric thickeners. Each of laureth and oleth forms of ethoxylated agents, each being linear ethoxylated fatty alcohols (each containing only 1 –OH or –COOH present in starting alcohol or acid), fully eliminated pilling with all of polymeric thickeners. In contrast, each of the polyglyceryl and PEG glyceryl cocoate forms are non-linear amphiphilic liquid RM with HLB 8.5-16 and structurally dissimilar from the ethoxylated agents employed in the study, did not beneficially diminish or eliminate pilling.

EXAMPLE 4: In Vivo Evaluation of Pilling

To demonstrate the benefit of the inventive composition in vivo, inventive and a comparative formulation (lacking emulsifier) were tested for pilling on human subjects according to a protocol similar to the in vitro test described above. The ethoxylated emulsifier agent included in the comparative formulations was laureth-4, present at 0% (comparative/baseline), 0.5% and 1% (inventives).

The results revealed that on human subjects, the formula with the most laureth-4 (1%) showed the least amount of pilling. The formula with no laureth-4 showed the most pilling. The formula with the lowest amount of laureth-4 (0.5%) showed intermediate pilling, but was improved over the baseline.

The articles "a" and "an," as used herein, mean one or more when applied to any feature in embodiments of the present invention described in the specification and claims. The use of "a" and "an" does not limit the meaning to a single feature unless such a limit is specifically stated. The article "the" preceding singular or plural nouns or noun phrases denotes a particular specified feature or particular specified features and may have a singular or plural connotation depending upon the context in which it is used. The adjective "any" means one, some, or all indiscriminately of whatever quantity.

“At least one,” as used herein, means one or more and thus includes individual components as well as mixtures/combinations.

The transitional terms “comprising,” “consisting essentially of,” and “consisting of,” when used in the appended claims, in original and amended form, define the claim scope with respect to what unrecited additional claim elements or steps, if any, are excluded from the scope of the claim(s). The term “comprising” is intended to be inclusive or open-ended and does not exclude any additional, unrecited element, method, step or material. The term “consisting of” excludes any element, step or material other than those specified in the claim and, in the latter instance, impurities ordinary associated with the specified material(s). The term “consisting essentially of” limits the scope of a claim to the specified elements, steps or material(s) and those that do not materially affect the basic and novel characteristic(s) of the claimed invention. All materials and methods described herein that embody the present invention can, in alternate embodiments, be more specifically defined by any of the transitional terms “comprising,” “consisting essentially of,” and “consisting of.”

Other than in the operating examples, or where otherwise indicated, all numbers expressing quantities of ingredients and/or reaction conditions are to be understood as being modified in all instances by the term "about," meaning within 10% of the indicated number (e.g., “about 10%” means 9% – 11% and “about 2%” means 1.8% - 2.2%).

All percentages and ratios are calculated by weight unless otherwise indicated. All percentages are calculated based on the total composition unless otherwise indicated. Generally, unless otherwise expressly stated herein, “weight” or “amount” as used herein with respect to the percent amount of an ingredient refers to the amount of the raw material comprising the ingredient, wherein the raw material may be described herein to comprise less than and up to 100% activity of the ingredient. Therefore, weight percent of an active in a composition is represented as the amount of raw material containing the active that is used, and may or may not reflect the final percentage of the active, wherein the final percentage of the active is dependent on the weight percent of active in the raw material.

All ranges and amounts given herein are intended to include subranges and amounts using any disclosed point as an end point. Thus, a range of “1% to 10%, such as 2% to 8%, such as 3% to 5%,” is intended to encompass ranges of “1% to 8%,” “1% to 5%,” “2% to 10%,” and so on. All numbers, amounts, ranges, etc., are intended to be modified by the term “about,” whether or not so expressly stated. Similarly, a range given of “about 1% to 10%” is intended to have the term “about” modifying both the 1% and the 10% endpoints. Further, it is understood that when an amount of a component is given, it is intended to signify the amount of the active material unless otherwise specifically stated.

Notwithstanding that the numerical ranges and parameters setting forth the broad scope of the disclosure are approximations, unless otherwise indicated the numerical values set forth in the specific examples are reported as precisely as possible. Any numerical value, however, inherently contains certain errors necessarily resulting from the standard deviation found in their respective testing measurements. The example that follows serves to illustrate embodiments of the present disclosure without, however, being limiting in nature.
