Description

Title of the invention: BENZOYL PEROXIDE FOAMING CLEANER technical field

[0001] The disclosure relates to a new foaming cleansing composition comprising large amounts of benzoyl peroxide which has a unique foam-like architecture and a pleasant texture upon application, which is gentle on the skin, stable and excludes undesirable surfactants and sulfates. CONTEXT

[0002] Benzoyl peroxide has been shown to be effective in treating skin conditions, including mild to moderate acne. Products with high concentrations of benzoyl peroxide offer the greatest potential for treating acne, but such formulations can be challenging. Not only are there practical limitations on the amount of benzoyl peroxide that can be included in formulations applied by consumers, but there are also limitations on formulating cleansers that are shelf-stable and provide a comfortable and pleasant experience for consumers. Typical over-the-counter benzoyl peroxide products contain relatively lower amounts of benzoyl peroxide, generally in the range of about 2.5% to about 4%. These formulations have cosmetic properties that are acceptable to consumers, although they have limited potency.There are over-the-counter formulations such as PanOxyl™ 10 that include 10% benzoyl peroxide. These formulations have increased potency but are harsh on the skin, containing irritating surfactants necessary to stabilize foaming cleansers. Current benzoyl peroxide formulations typically have a thin, lotion-like texture with modest lather. These various formulations offer a limited sensory experience for the consumer, and keeping them on the skin during cleansing can be challenging due to their runny nature. This can be particularly bothersome in the shower, especially on areas like the back and shoulders. Furthermore, the relative instability of benzoyl peroxide formulations is evident in the thinning and reduced lather over time at room temperature.

[0003] The inventors have overcome these challenges and propose a foaming cleaning composition that has a unique foam-like architecture that remains stable over time at ambient temperatures and resists freeze / thaw cycles, where stability is demonstrated by minimal variation in pH and viscosity and visible properties of the foaming cleansing formula. SUMMARY

[0004] According to various embodiments, the disclosure proposes a foaming cleansing composition comprising 2.5% to 12.0% benzoyl peroxide, at least one acrylate polymer, hyaluronic acid, niacinamide, a combination of anionic and amphoteric surfactants, expressly excluding alkyl polyglucosides, and water. The composition offers a unique textural sensation compared to existing products containing benzoyl peroxide, and in particular, is formulated as an opaque gel with a light, fluffy foam-like architecture and a viscosity that is retained on the skin during application and resists dripping, even in the shower. The composition is ray-stable and application-stable, demonstrating a viscosity of approximately 18-25 UD (Rheomat viscosity M3) and a pH of approximately 5.5 to approximately 6.5.

[0005] In some embodiments, benzoyl peroxide is present at approximately 10% by weight relative to the total weight of the foaming cleaning composition.

[0006] In some embodiments, at least one acrylate polymer is present in the foaming cleaning composition from about 0.1% to about 5.0%, by weight relative to the total weight of the foaming cleaning composition.

[0007] In some embodiments, hyaluronic acid is present in the foaming cleansing composition from about 0.1% to about 2.0%, by weight relative to the total weight of the foaming cleansing composition.

[0008] In some embodiments, niacinamide is present in the foaming cleansing composition from about 0.1% to about 2.0%, by weight relative to the total weight of the foaming cleansing composition.

[0009] In some embodiments, the total amount of surfactant in the combination of anionic and amphoteric surfactants is present in the foaming cleansing composition from about 4% to about 15%, by weight relative to the total weight of the foaming cleansing composition.

[0010] In certain embodiments, each surfactant in the combination of anionic and amphoteric surfactants is present in the foaming cleansing composition from approximately 0.05% to approximately 15%, by weight relative to the total weight of the foaming cleansing composition.

[0011] In some embodiments, 1' at least one acrylate polymer comprises a C10-30 alkyl acrylate / acrylate crosslinked polymer.

[0012] In some embodiments, the combination of anionic and amphoteric surfactants is chosen from the group consisting of sultaines, sulfonates, betaines, amphoacetates, amphopropionates, and their combinations.

[0013] In certain embodiments, the combination of anionic and am- surfactants Photeres includes cocamidopropyl hydroxysultaine and sodium Cl4-16 olefin sulfonate.

[0014] In some embodiments, the composition excludes alkyl polyglucosides selected from the group consisting of Decyl Glucoside, lauryl glucoside, octyl glucoside, coco glucoside, caprylyl / capryl glucoside, and sodium lauryl glucose carboxylate, and their combinations.

[0015] In some embodiments, the composition has a pH of about 5.5 to about 6.5.

[0016] In some embodiments, the composition has a viscosity of approximately 18-25 UD.

[0017] In some embodiments, the composition comprises at least one additional compound selected from the group consisting of pH adjusters, chelating agents, alcohols, antimicrobials, preservatives, vitamins, perfumes, humectants, emulsifiers and combinations thereof.

[0018] In certain embodiments, the foaming cleansing composition is free or essentially free of sulfates, oils, silicones, cationic compounds and combinations thereof.

[0019] In some embodiments, the disclosure proposes a foaming cleansing composition, comprising:

[0020] Approximately 10.0% benzoyl peroxide; at least one acrylate polymer, the acrylate polymer comprising a C10-30 alkyl acrylate crosslinked polymer present from approximately 0.1% to approximately 5.0%; approximately 0.1% to approximately 2.0% hyaluronic acid; approximately 0.1% to approximately 2.0% niacinamide; approximately 4.0% to approximately 15.0% of a combination of anionic and amphoteric surfactants, expressly excluding alkyl polyglucosides; water; and at least one compound selected from the group consisting of pH adjusters, chelating agents, alcohols, antimicrobials, preservatives, vitamins, perfumes, humectants, emulsifiers and combinations thereof, all in weight amounts relative to the weight of the composition, wherein the composition has a foam-like architecture, a pH of about 5.5 to about 6.5, and a viscosity of about 18-25 UD.

[0021] In certain embodiments, the foaming cleansing composition is free or essentially free of sulfates, oils, silicones, cationic compounds and combinations thereof.

[0022] In certain embodiments, the disclosure proposes a method for cleansing and improving acne-prone skin, comprising: providing a foaming cleansing composition according to claim 1, wherein the composition is contained and distributed in the form of a foam; the initial rubbing of the composition onto the skin, after which foaming is accomplished while being retained on the skin; rinsing to remove the composition.

[0023] It is known in the art that the inclusion of benzoyl peroxide is associated with thinning over time, so benzoyl peroxide-based products tend to run during a typical shelf life. Therefore, it is difficult to formulate products containing sufficient amounts of active benzoyl peroxide to deliver desirable results in a pleasant form. The inventors have proposed a 10% benzoyl peroxide composition that addresses these challenges. The inventive composition offers a unique textural feel compared to existing benzoyl peroxide-containing products and, in particular, is formulated as a lightweight, fluffy mousse-like structure with a viscosity that is retained on the skin during application and resists dripping, even in the shower.

[0024] Comparatives include alkyl polyglycoside surfactants, which may be associated with allergenic properties and are considered to be affected by increased amounts of benzoyl peroxide, resulting in undesirable effects on viscosity. Therefore, cleaners with a high benzoyl peroxide content (2-10% benzoyl peroxide) are known to be runny and stringy with low viscosity.

[0025] The invention eliminates alkyl polyglucoside surfactants and replaces thickeners such as xanthan gum with acrylate polymer thickeners that demonstrate salt tolerance to low pH and tolerance to high levels of surfactants. Formulated to be free of alkyl polyglucoside surfactants, sulfates, parabens, and other ingredients unfavorable to the consumer, the foaming cleansing composition exemplified herein contains 10% benzoyl peroxide, acrylate polymer, hyaluronic acid, and niacinamide, and a combination of anionic and amphoteric surfactants and emulsifiers in a pleasant, foamy lather that is stable in radius and stable during application, demonstrating a viscosity of approximately 18-25 UD (Rheomat viscosity pin M3), and a pH of approximately 5.5 to approximately 6.5.The innovative foaming cleansing formula delivers a high concentration of active benzoyl peroxide to maximize skin benefits and provide a pleasant consumer experience.

[0026] As exemplified herein, the inventors have prepared formulations in which key ingredients have been replaced in series, in particular, a thickener (acrylate polymer), a replacement of surfactants with alkyl polyglucoside surfactants, and the elimination of hyaluronic acid and / or niacinamide, demonstrating the contribution of the components to a composition whose feel, viscosity, and shelf-life stability are achieved in the inventive composition. Thus, while hyaluronic acid offers the benefits of retaining the skin's natural moisture, skin and that niacinamide offers soothing skin-healing benefits, these components also unexpectedly prove important in providing a foam-like architecture that also delivers an effective and pleasant lather upon application to enhance the cleansing experience.

[0027] As used here, the term "keratinous substrate" is intended to include skin and hair.

[0028] As used here, the term "stability," with respect to a cleaning composition, refers to the cleaning composition remaining in a stable, mixed viscosity state with a generally homogeneous bubble and a benzoyl peroxide dispersion in which the foaming cleaning composition does not exhibit appreciable thinning or separation, such as non-phase separation, and retains a foam-like architecture-type foam structure. Such properties are obtained by including large amounts of benzoyl peroxide (from about 2.5%, and more than 4% and up to about 12%), which is typically associated with significant thinning and a loose bubble structure in prior art compositions.

[0029] As used herein, the terms "foam" and "foam-like architecture" and "foam shape" and "foam texture" refer to an architecture (or shape) of a foam when applied, containing suspended and dispersed bubbles.

[0030] "Stability" is attested by visual inspection or by direct measurement of viscosity, or by both. For the purposes of this formulation, a composition that demonstrates physical stability and does not thin, lose its foam structure, and maintain a dispersion of benzoyl peroxide is stable. In various embodiments, an inventive composition remains stable at temperatures in the range of approximately 4°C to approximately 35°C, over a period of at least one month, or at least two months, or at least three months, or more, or any intermediate value, range, or sub-range. In some embodiments, a cleaning composition is stable at 25°C for at least one month, or at least two months, or at least three months, or more, or any intermediate value, range, or sub-range.In some embodiments, a cleaning composition is stable at 37°C for at least one month, or at least two months, or at least three months, or longer, or any intermediate value, range, or sub-range. As disclosed and illustrated herein, a cleaning composition is stable at 4°C for at least one month, or at least two months, or at least three months, or longer, or any intermediate value, range, or sub-range.

[0031] The terms "essentially free of alkyl polyglycoside surfactants", "essentially free of alkyl polyglycoside surfactants", "essentially free of alkyl polyglycoside surfactants" and "essentially free of alkyl polyglycoside surfactants" refer to the substantial absence of levels of alkyl polyglycoside surfactants in the cleaning composition of the present invention.

[0032] The terms "essentially sulfate-free," "essentially sulfate-based surfactant-free," "essentially sulfate-based surfactant-free," and "essentially sulfate-free" refer to the substantial absence of sulfate content in the foaming cleaning composition of the present invention. With reference to certain embodiments, the term "sulfate-free" means that sulfate has not been added as a component. With reference to certain embodiments, the foaming cleaning composition is free of sulfates. With reference to certain embodiments, the foaming cleaning composition is free of or devoid of sulfates, which may include, but are not limited to, anionic alkyl sulfates and alkyl ether sulfates.With reference to certain embodiments, although it is preferable that no sulfate-based surfactants be present in the foaming cleansing composition, it is possible to have very small amounts of sulfate-based surfactants in the foaming cleansing composition of the invention, provided that these amounts do not materially affect the advantageous properties of the foaming cleansing composition, particularly with regard to skin softness. Thus, a sulfate-based surfactant may be present in the foaming cleansing composition in an amount of less than approximately 0.2% by weight, or less than approximately 0.1% by weight, or less than approximately 0.05% by weight, or approximately 0% by weight, relative to the total weight of the foaming cleansing composition.In some embodiments, the foaming cleansing composition is free from cationic compounds, sulfate-based surfactants, or any combination thereof. In some embodiments, the foaming cleansing composition is free from sulfate-containing compounds, in particular, but not limited to, sodium lauryl sulfate, sodium laureth sulfate, sodium lauryl ether sulfate, ammonium lauryl sulfate, ammonium laureth sulfate, or any combination thereof.

In exemplary embodiments, the polymeric thickener is a C10-30 acrylate / alkyl acrylate crosslinked polymer.

[0040] Polymer thickeners have high electrolytic properties and exhibit high salt tolerance, so they can thicken in media containing high or low amounts of salts, whether acidic or basic, and include a wide variety of ingredients. Electrolyte-rich polymers include repeating motifs Polymers that carry an electrolyte group, which may include polycations and polyanions. These groups dissociate in aqueous solutions (water), making the polymers charged. Many biological molecules are polyelectrolytes, such as polypeptides, glycosaminoglycans, and DNA.

A person with ordinary skill in the art will, however, appreciate that other ranges fall within the scope of the invention.

[0044] In certain specific embodiments, the foaming cleaning composition comprises a C10-30 acrylate / alkyl acrylate crosslinked polymer, alone or with xanthan gum and carbomer. In certain specific embodiments, the foaming cleaning composition comprises a C10-30 acrylate / alkyl acrylate crosslinked polymer, alone or with xanthan gum and carbomer, and excludes the polyacrylate-6 crosslinked polymer.
