Description

Title of the invention: HIGH SALICYLIC ACID, SULFATE AND PEG-FREE CLEANING COMPOSITION FIELD OF THE INVENTION

[0001] This disclosure relates to a cleaning composition with a high salicylic acid content. CONTEXT OF THE INVENTION

[0002] Acne is a common skin condition and is treated with various agents. Salicylic acid, a mild beta-hydroxy acid known to facilitate the removal of dead skin cells and other cellular debris, is often used in the treatment of acne, as well as other skin conditions including psoriasis, keratoses, and ichthyosis. Commercial forms of cosmetic products that include salicylic acid include scrubs, cleansers, and leave-on treatments in the form of lotions, creams, and makeup. Salicylic acid is known to have very low solubility in water and is prone to recrystallization, particularly at high temperatures.Consequently, one of the problems posed by many of these products is that they deliver salicylic acid that is only temporarily available on the skin, as in cleansers and scrubs, or that is in relatively small quantities, thus preventing lasting effectiveness on the skin to combat acne and other skin conditions that benefit from the agent.

[0003] Compositions with a salicylic acid concentration exceeding 1% present the problem of phase separation or crystallization and are also prone to cloudiness with a transparency of less than 100%. Stable solubilization of salicylic acid in quantities of 1% by weight or more can be achieved using solubilizing thickeners and surfactants containing polyethylene glycol (PEG) and sulfates. While these ingredients provide stability to salicylic acid, they cause dryness and discomfort to the skin and are increasingly unpopular with consumers. Without sulfates and / or PEG, the weakness of salicylic acid is precipitation, which not only affects the availability of the active ingredient for treatment but also negatively impacts product stability.

[0004] Consequently, there is a need for a composition that overcomes the shortcomings of the prior art and offers benefits that include a stable formulation with high amounts of salicylic acid that demonstrates the ability to cleanse the skin and provide a persistent delivery of a skin active ingredient, for example, salicylic acid. salicylic acid and its derivatives. The present invention proposes such a composition which remains surprisingly stable in the absence of PEG and sulfates and demonstrates efficacy in delivering and depositing active ingredients on the skin, in particular salicylic acid and its derivatives.

[0030] It must be understood that both the preceding general description and the detailed description that follows are provided by way of example and explanation only, and do not limit the invention. DETAILED DESCRIPTION OF THE INVENTION

[0031] The cleansing composition overcomes the shortcomings of the art regarding the instability induced by salicylic acid in cleansing compositions. Although sulfate- and PEG-based surfactants and solubilizers are necessary to achieve stability at high amounts of salicylic acid, the inventors have unexpectedly shown that the inventive cleansing composition, as disclosed and given by way of example herein, demonstrates 100% transparency and stability from crystallization, precipitation, and phase separation; has a pleasant lather; is thick and non-drip, allowing for easy application to the skin and retention on the skin before rinsing; and demonstrates the deposition and retention of effective amounts of beta-hydroxy acid, for example, salicylic acid, even after rinsing.

[0032] The benefits of the inventive composition are remarkably achieved in the absence of PEG- and sulfate-containing ingredients, which are commonly used, accepted, and understood in the art as necessary to solubilize and stabilize large quantities of SA. These PEG- and sulfate-containing ingredients are expressly excluded from the inventive composition. The composition has a viscosity in the range of approximately 15 UD to approximately 50 UD, which is necessary to provide retention on the skin and resistance to runoff before rinsing, and more particularly in the range of approximately 25 UD to approximately 35 UD. In contrast, examples of comparative compositions lacking the specific combination of claimed ingredients are unstable and much more liquid, demonstrating negligible viscosity, and therefore unsuitable for retention on the skin before rinsing, and much less effective for depositing SA on the skin.Furthermore, although a reference composition containing PEG and sulfate ingredients and high amounts of salicylic acid demonstrates stability and viscosity within an acceptable range, it has a viscosity less than half the average viscosity of the embodiments of the inventive compositions, all of which have a viscosity greater than 30 UD.

[0033] The inventors have demonstrated a clear solution to the problems associated with the use of less desirable PEG and sulfate-containing ingredients to accomplish the solubilization of SA, offering a composition with a pleasant and desirable smooth and foamy feel that avoids the drying effects of PEG and sulfates.

[0034] The improved deposition and retention of salicylic acid was demonstrated herein by visual observation (naked eye), the deposition was evaluated by in vitro tests on synthetic skin (Bio skin), and the foaming was demonstrated by a foaming analyzer as mentioned herein.

[0035] In addition, the inventive cleansing composition demonstrates stability from phase separation, high foaming quality, high transparency (free from clouding) and a gentle aesthetic when applied to the skin. DEFINITIONS

[0036] The term “skin,” as used here, includes cutaneous materials containing keratin, such as facial and body skin, scalp, eyebrows, and lips. As mentioned in the examples here, Bioskin is a substrate manufactured in the form of a pseudo-skin that is a skin substitute and is known in cosmetics and other industries for its representative resemblance to keratinous substrates, such as skin.

[0037] “Keratinous substrate” and “keratinous tissue” each include, but are not limited to limit, skin, hair and nails.

[0038] The term “cleanser” as used herein can be any cleansing composition used for application to keratinous tissue for skin cleansing, makeup removal and the like.

[0039] “Natural” or “of natural origin” as used herein mean and refer to, cosmetically acceptable materials and components that are one or more of those of direct natural origin, that are of natural origin with minimal processing, and that are derivatives of materials of natural origin. The cleansing composition according to this disclosure is, in certain embodiments, up to 99.11% natural, or "Highly Natural" or "Completely Natural," meaning that all carbon atoms of intentionally added ingredients come from natural sources in accordance with ISO 16128.

[0040] References to "foaming" and "high foaming" as used herein refer to visually observed foaming and the measurement of the absolute or relative height of a formulation after stirring and the measurement of the height of foam generated using an analyzer (e.g., Kruss DFA100 dynamic foam analyzer).

[0041] As used herein with respect to the foaming property of the cleansing composition, the term "foaming" designates and refers to the ability of a composition (inventive or comparative) to develop a foam upon massage, which would be associated with the application and gentle cleansing of the skin or other keratinous substrates with the formulation. Reference is made to a known test method. The establishment of in vitro foam formation using equipment well-known in the art, namely analysis using a Krauss DFA100™ dynamic foam analyzer, provides a relative measure of the foam formation obtained, as described in more detail here. In some examples, foaming is described as the relative density of foam formation per unit area compared to other formulations tested under the same conditions. In some examples, the bubble count using the specified foam analyzer is provided. Foaming capability, or good foaming or high foaming as used here, compared to foaming on a keratinous substrate, such as facial skin, is based on a scale from low to high.

[0042] “Stable” and “Stability” as used herein mean that the cleaning composition shows no signs of significant changes in one or more of the following: color, odor, pH, or viscosity at room temperature and at temperatures in the range of approximately 25°C to approximately 45°C. In various embodiments, an inventive composition remains stable at temperatures in the range of approximately 25°C to approximately 45°C for a period of time of at least one month, or at least two months, or any intermediate value, range, or sub-range. The cleaning composition is stable at 45°C for three months, wherein stability includes a clear (100% transparent) appearance with no cloudiness, no loss of viscosity, and no formation of crystals or precipitation, for example, no precipitation of salicylic acid.For example, as described here, the use of certain naturally occurring thickeners, such as chitosan, polyethyleneimine (PEI) or polylysine, resulted in unstable compositions in which there was distinct phase separation.

[0043] References to "free from turbidity" as used herein mean that the cleaning composition is essentially 100% clear, which probably means that all of the salicylic acid is essentially maintained in solubilized, clear or free from turbidity form, which can be visually confirmed on the basis of the absence of crystals and the absence of turbidity, and more specifically by means of a spectrophotometer or similar instrument to measure the type and amount of light passing through in which 100% light transmission (using, for example, a Varian Cary 5000 uv-vis-nir spectrophotometer) is equivalent to = 100% clear and free from turbidity.

[0044] The foaming cleansing composition may include, consist of, or consist essentially of the essential elements and limitations of the invention described herein, together with any additional or optional ingredients, components or limitations described herein or otherwise useful.

[0046] According to the various embodiments, the cleansing composition comprises at least one acne treatment active ingredient comprising a beta-hydroxy acid. In certain specific embodiments, the cleansing composition includes a beta-hydroxy acid comprising salicylic acid.

[0047] In some embodiments according to the disclosure, the cleaning composition includes salicylic acid present in the cleaning composition in an amount ranging from about 0.2% to about 2% by weight, relative to the total weight of the cleaning composition.

[0048] In some embodiments, the beta-hydroxy acid is salicylic acid present in the cleaning composition at approximately 1%, or approximately 1.5%, or approximately 2% by weight, relative to the weight of the composition.

[0049] The term "beta-hydroxy acid" is understood, according to the present invention, to mean a carboxylic acid having a hydroxyl functional group and a carboxyl functional group separated by two carbon atoms. A beta-hydroxy acid may be present in the cleaning composition in the form of the free acid and / or in the form of one of its associated salts (salts with an organic base or an alkali metal, in particular), depending notably on the final pH imposed on the cleaning composition.

[0172] The stability of each composition was evaluated, including visual indicators of stability, including precipitation, turbidity; viscosity and deposition on a skin-like substrate.

[0173] Each of the listed inventive and comparative formulations was visually evaluated with the naked eye for clarity (cloudiness) and stability at two months under ambient conditions of 25°C, where the comparative formulations were each differentiated from invention 1 in that they did not contain lauryl lactate, or one or more ingredients were replaced, as indicated.

[0174] [Table 5]

[0175] Table 5: Stability Results Composition Performance (Formulations evaluated after 2 months at 25°C) INV1 No phase separation; 100% transparency; No SA recrystallization INV2 No phase separation; 100% transparency; No SA recrystallization INV3 No phase separation; 100% transparency; No SA recrystallization Reference No phase separation; 100% transparency; No SA recrystallization COMP1 Unstable: Phase separation; cloudiness; SA recrystallization COMP2 Unstable: Phase separation; Poor SA deposition on skin COMP3 Unstable: Phase separation COMP4 Unstable: Phase separation COMP 5 Unstable: Phase Separation

[0176] With reference to the results shown in Table 5, the comparative formulations all demonstrated instability at 2 months, while the embodiments of the inventive composition tested remained stable beyond two months and, moreover, demonstrated stability at 45°C after a period of three months. Furthermore, only the inventive formulations demonstrated phase stability, clarity (absence of cloudiness – assumed to represent sustained solubilization of salicylic acid in the presence of lauryl lactate), and satisfactory deposition of SA on the skin.

[0177] The results with substituted cationic agents surprisingly and unexpectedly show that the mere inclusion of a cationic agent, such as a naturally occurring cationic agent like chitosan or a polyamine, is not sufficient to provide a stable composition. Similarly, the results with substituted surfactants surprisingly and unexpectedly show that an amphoteric surfactant such as coco betaine alone is insufficient to provide a stable composition, whereas a combination of amphoteric and anionic surfactants provides a stable composition.

[0178] Embodiments of the inventive compositions were also evaluated against the reference composition for comparative performance in terms of stability and salicylic acid deposition on the skin. Both the inventive and reference compositions demonstrated stability. After rinsing with Bio skin in vitro substrates, positive retention of salicylic acid on the skin was observed for both the inventive and reference compositions, with comparable results. These results compared to the reference unexpectedly demonstrate that a composition free of sulfates and PEG-based surfactants can stabilize high amounts of salicylic acid. Example 4#: Viscosity and Sa deposition

[0179] Viscosity was measured in UD units using a Rheomat R180 viscometer with an M3 spindle for approximately 10 minutes at 25 °C. The stable inventive compositions demonstrate viscosity in the range of approximately 15 UD to approximately 50 UD (M3). In some particular embodiments, the viscosity is in the range of approximately 25 UD to approximately 35 UD. Unsatisfactory compositions are considered unstable at viscosities below 15 UD or above 50 UD. For example, as described herein, the use of certain surfactants, such as coco-betaine alone in the absence of other surfactants, resulted in unstable and / or insufficient viscosity.

[0180] Salicylic acid deposition test

[0181] Processing of BIOSKIN samples: BIOSKIN samples approximately 2 inches by 2 inches were provided. Each BIOSKIN sample was processed with one of an inventive, exemplary, and comparative composition by applying approximately 0.5 g of the test composition with a cleaning brush (Clarisonic™ brush). The cleaned samples were soaked in water at 40°C for approximately 30 seconds, then massaged with the cleaning brush for approximately one minute. The samples were then rinsed under water at 40°C and air-dried for approximately one hour. The samples were then soaked in a 0.01% iron chloride solution (FeCl3) for approximately one hour and then air-dried overnight.

[0182] The color of each treated BIOSKIN sample (compared to an untreated control sample) was measured using a handheld colorimeter, and the measurements were analyzed to provide a color change (resulting from the binding of the iron compound to the deposited SA) expressed as a percentage color change relative to the control. The results are shown in Table 6 below.

[0183] [Table 6]

[0184] Table 6: Viscosity and deposition of salicylic acid with inventive, comparative and reference compositions Reference Inventive 1 Inventive 2 Inventive 3 Comparative 1 Sulfate surfactant + 2% SA Lauryl lactate + 2% SA Lauryl lactate + 1% SA Lauryl lactate + 1.5% SA No lauryl lactate + 2% SA % mean color change 16.89 19.46 17.33 18.25 11.35 Viscosity (M3) UD 15.6 35.7 30.5 33.1 < 0 out of range

[0185] With reference to the results shown in Table 5, it is clear that each embodiment of the inventive composition demonstrates a significant level of SA deposition on the synthetic skin, based on the measured color change, and the extent of deposition is comparable to the reference. Furthermore, each embodiment of the inventive composition demonstrates a viscosity in the range of approximately 15 UD to approximately 50 UD, which is necessary to confer retention on the skin and resistance to runoff before rinsing, whereas the comparative composition is much more liquid, demonstrating negligible viscosity, and therefore unsuitable for retention on the skin before rinsing, and much less effective for SA deposition. on the skin. Furthermore, although the Reference demonstrates a viscosity within an acceptable range, it is less than half the viscosity of the embodiments of the inventive compositions, all of which have a viscosity greater than 30 UD.

[0186] Therefore, as the examples above show, the inventive composition provides a stable architecture that is sufficiently thick and spreadable to facilitate application to the skin and the associated retention of effective amounts of SA on the skin after rinsing. This is remarkably accomplished in the absence of ingredients containing PEG and sulfate, which are commonly used, accepted, and understood in the art as necessary to solubilize and stabilize large quantities of SA, and which ingredients are expressly excluded from the inventive composition.

[0187] Although the disclosure has been described with reference to described embodiments, it will be understood by those skilled in the art that various modifications can be made and equivalents can be substituted for elements thereof without departing from the scope of the disclosure. Furthermore, numerous modifications can be made to adapt a particular situation or material to the teachings of the disclosure without departing from its essential scope. Therefore, it is intended that the disclosure will not be limited to the particular embodiment disclosed as the best envisaged means of carrying out this disclosure, but that the disclosure will include all embodiments falling within the scope of the appended claims.
