[0001] This application claims benefit of and priority to US Application No. 18 / 680,694 filed on May 31, 2024, as well as claiming priority to French Application No. 2408967 filed on August 19, 2024, the entireties of which are incorporated herein by reference.FIELD OF THE INVENTION

[0002] The present disclosure is directed to a cleansing composition with high salicylic acid content.BACKGROUND OF THE INVENTION

[0003] Acne is a common skin disorder and is treated using a variety of different agents. Salicylic acid, a mild beta-hydroxy acid, known for facilitating sloughing of dead skin cells and other cellular debris, is often used in treating acne, as well as other skin conditions that include psoriasis, keratoses, and ichthyoses. Commercial forms of cosmetic products that include salicylic acid include peels, cleansers, and leave on treatment in the forms of lotions, creams, and make ups. It is known that salicylic acid exhibits a very low solubility in water, and is prone to re- crystalize, especial at high temperature. Accordingly, a challenge with many of these product forms is that they deliver salicylic acid that is only transiently available on the skin, such as in cleansers and peels, or that is in relatively low amounts, thus precluding sustained effectiveness on the skin for addressing acne and other skin conditions that benefit from the agent.

[0004] Compositions with a concentration of salicylic acid that is greater than 1% present the challenge that they are vulnerable to phase separate or crystallization, and are also prone to being hazy with less than 100% transparency. Stable solubilization of salicylic acid in amounts of 1% or more, by weight, can be achieved using solubilizing thickeners and surfactants that contain polyethylene glycol (PEG) and sulfates, which ingredients confer stability of salicylic acid but cause dryness and discomfort for skin, and are increasingly disfavored by consumers. Without sulfates and / or PEG, salicylic acid is vulnerable to precipitation, affecting not only the availability of the active for treatment, but also adversely affecting the stability of the product.

[0005] Accordingly, there is a need for a composition that overcomes the shortcomings of the prior art and provides benefits that include a stable formulation with high amounts of salicylic acid that demonstrates the ability to cleanse skin and provide persistent delivery of a skin active, for example, salicylic acid and derivatives thereof. The present invention provides such a composition that surprisingly remains stable in the absence of PEG and sulfates and demonstrates efficacy to deliver and deposit actives to skin, particularly salicylic acid and derivatives thereof.BRIEF SUMMARY OF THE INVENTION

[0028] It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention.DETAILED DESCRIPTION OF THE INVENTION

[0029] The cleansing composition overcomes shortcomings in the art pertinent to salicylic acid induced instability in cleansing compositions. While sulfate and PEG based surfactants and solubilizers are required to obtain stability at high amounts of salicylic acid, the inventors have unexpectedly shown that the inventive cleansing composition, as disclosed and as exemplified herein, demonstrates 100% transparency and stability from crystallization, precipitation and phase separation, has pleasing foam, is thick and non-runny, allowing ease of application to skin and retention on skin prior to rinsing, and demonstrates deposition and retention of effective amounts beta hydroxy acid, for example, salicylic acid, even after rinsing.

[0030] The benefits of the inventive composition are surprisingly accomplished in the absence of PEG and sulfate containing ingredients that are commonly employed and accepted and understood in the art to be necessary for solubilizing and stabilizing large amounts of SA, which PEG and sulfate containing ingredients are expressly excluded from the inventive composition. The composition has a viscosity in a range from about 15 UD to about 50 UD which is required to confer retention on skin and resistance to runniness prior to rinsing, and more particularly in a range from about 25 UD to about 35 UD. In contrast, exemplified comparative compositions lacking the specific combination of claimed ingredients is unstable, and far more liquidous, demonstrating a negligible viscosity, and thus unsuitable for retention on skin prior to rinsing, and far less effective for deposition of SA on skin. Further, while a Benchmark composition which contains PEG and sulfate ingredients and high amounts of salicylic acid demonstrates stability and viscosity in an acceptable range, it has a viscosity that is less than half of the average viscosity of the embodiments of the inventive compositions, all of which have a viscosity of greater than 30 UD.

[0031] The inventors have demonstrated a clear solution to the problems associated with use of less desirable PEG and sulfate containing ingredients for accomplishing solubilization ofSA, providing a composition with a pleasant and desirable foamy and smooth feel that avoids the drying effects of PEG and sulfates.

[0032] The deposition and enhanced salicylic acid retention was demonstrated herein by visual (unaided eye) observation, deposition was evaluated by in vitro testing on synthetic skin (Bio skin), and foaming was demonstrated by foaming analyzer as discussed herein.

[0033] In addition, the inventive cleansing composition demonstrates stability from phase separation, high foaming quality, high transparency (free from hazing) and a mild aesthetic when applied to skin.

[0172] EXAMPLES

[0173] The following examples are intended to further illustrate the present disclosure. They are not intended to limit the disclosure in any way. Unless otherwise indicated, all parts are by weight.

[0174] EXAMPLE 1: Raw Materials

[0175] An embodiment of the inventive cleansing composition is provided in Table 1.

[0176] The examples below according to the invention are given by way of illustration and without a limiting nature. The names are the chemical name or the INCI name. Compositions and systems as described in the representative embodiments herein are selected from commercially available materials, including, as shown in the exemplified embodiments herein below.

[0177] Embodiments of the inventive cleansing composition as exemplified herein include the foregoing raw materials wherein the active constituents of the raw materials are listed as discrete ingredients and the amounts of active ingredients are given for the exemplified compositions as % by weight of the active ingredients based on the weight of the entire composition, and not as amounts of raw materials except as may be expressly stated

[0178] TABLE 1: Raw Materials

[0179] EXAMPLE 2: Compositions

[0180] Exemplary embodiments of the cleansing composition according to the disclosure are set forth in Table 2, Comparative compositions are set forth in Table 3, and a comparative Benchmark composition is set forth in Table 3, all below.

[0181] Table 2: Inventive and Comparative Compositions

[0182] Inventive 1

[0183] The inventive 1 composition includes salicylic acid (2); capryloyl salicylic acid (0.5), lauryl lactate (0.65), cocamidopropyl hydroxysultaine (7.5), sodium methyl cocoyl taurate (4.8), polyquaternium-47 (0.105), glycerin (5); hexylene glycol (0.5), sodium hydroxide; menthol; zinc gluconate; tetrasodium glutamate diacetate; sodium benzoate; sodium chloride (total of ~3 -- ~0.4, 0.1, 0.2, 0.05, 0.001, 2.1, respectively), all amounts percentage (%) by weight, based on the weight of the composition.

[0184] Table 3: Comparative Compositions

[0185] Table 4: Benchmark composition (PEG, and sulfate surfactant containing cleanser that lacks cleansing composition of the invention)

[0186] Example 3: Stability

[0187] Each composition was evaluated for stability, including visual indicia of stability including precipitation, hazing; viscosity; and deposition on skin like substrate.

[0188] Each of the listed inventive and comparative formulations were evaluated visually by the unaided eye for clarity (haze) and stability at two months in ambient 25 °C conditions, wherein the comparatives each were varied from Inventive 1 in that they lacked lauryl lactate, or one or more ingredients were substituted, as indicated.

[0189] Table 5: Stability Results

[0190] Referring to the results shown in Table 5, the comparatives all demonstrated instability at 2 months, while the tested embodiments of the inventive composition remained stable beyond two months, and further demonstrated stability at 45 °C after a period of three months. In addition, only the inventive formulations demonstrated phase stability, and clarity (lack of haze- being posited to represent maintained solubilization of the salicylic acid om the presence lauryl lactate), and satisfactory deposition of SA on skin, the latter.

[0191] Results with the substituted cationic agents surprisingly and unexpectedly show that mere inclusion of any cationic agent, such as a nature based cationic agent such as chitosan or apolyamine, is not sufficient to provide a stable composition. Likewise, results with the substituted surfactants surprisingly and unexpectedly show that an amphoteric surfactant such as coco betaine alone is insufficient to provide a stable composition, while a combination of amphoteric and anionic surfactants provide a stable composition.

[0192] Embodiments of the inventive compositions were also evaluated vs the benchmark composition for comparative performance of stability and deposition of salicylic acid on skin. Both the inventive and benchmark compositions demonstrated stability. After rinsing using Bio skin in vitro substrates, positive retention of salicylic acid on skin was observed for both inventive and benchmark with comparable results. These results vs benchmark demonstrate unexpectedly that a composition lacking sulfates and PEG based surfactants can stabilize high amounts of salicylic acid.

[0193] Example 4: Viscosity And Sa Deposition

[0194] Viscosity was measured in the UD units by viscometer Rheomat R180 using an M3 spindle for ~ 10 minutes at 25 °C. Stable inventive compositions demonstrate viscosity in a range from about 15 UD to about 50 UD (M3). In some particular embodiments, the viscosity is in the range from about 25 UD to about 35 UD. Unsatisfactory compositions are deemed unstable at viscosities that fall below 15 UD or exceed 50 UD. For example, as described herein, use of certain surfactants, such as coco-betaine alone in the absence of other surfactants, resulted in unstable and / or insufficient viscosity.

[0195] Salicylic Acid Deposition Test

[0196] Processing of BIOSKIN Samples: BIOSKIN samples of about 2 in by 2 inches were provides. Each BIOSKIN sample was treated with one of an inventive, example and comparative composition by application of about 0.5 g of the tested composition with a cleansing brush (Clarisonic (TM) brush). Cleansed samples were soaked in water for about 30 seconds in 40 °C water, then massaged using the cleansing brush for about one minute. The samples were then rinsed under water at in 40 °C water then air dried for about an hour. Samples were then soaked in a solution of iron chloride (0.01% FeCh) for about an hour then air dried overnight.

[0197] The color of each sample of treated BIOSKIN (vs a control sample lacking any treatment) was measured using a hand-held colorimeter and the measurements were analyzed to provide a color change (resulting from binding to the iron compound to deposited SA) reflected as a percentage change in color relative to the control. The results are shown in Table 6, below.

[0198] Table 6: Viscosity And Salicylic Acid Deposition with Inventive, Comparative and Benchmark Compositions

[0199] Referring to the results shown in Table 5, it is clear that each embodiment of the inventive composition demonstrates a significant level of deposition of SA on the synthetic skin, based on the measured color change, and the extent of deposition is comparable to the benchmark. Further each embodiment of the inventive composition demonstrates viscosity in a range from about 15 UD to about 50 UD which is required to confer retention on skin and resistance to runniness prior to rinsing, while the comparative composition is far more liquidous, demonstrating a negligible viscosity, and thus unsuitable for retention on skin prior to rinsing, and far less effective for deposition of SA on skin. Further, while the Benchmark demonstrates viscosity in an acceptable range, it is less than half of the viscosity of the embodiments of the inventive compositions, all of which have a viscosity of greater than 30 UD.

[0200] Accordingly, as shown in the above Examples, the inventive composition provides a stable, and sufficiently thick and spreadable architecture for ease of application to skin and associated retention of effective amounts of SA on skin after rinsing. This is surprisingly accomplished in the absence of PEG and sulfate containing ingredients that are commonlyemployed and accepted and understood in the art to be necessary for solubilizing and stabilizing large amounts of SA, which ingredients are expressly excluded from the inventive composition.

[0201] While the disclosure has been described with reference to described embodiments, it will be understood by those skilled in the art that various changes may be made, and equivalents may be substituted for elements thereof without departing from the scope of the disclosure.

The adjective "any" means one, some, or all indiscriminately of whatever quantity.

[0204] "At least one" or "one or more" as used herein, means that there may be one, two, three or more and thus includes individual components as well as mixtures / combinations.

[0205] 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.
