Description

Title of the invention: Micellar cleansing composition based on a biosurfactant FIELD OF INVENTION

[0001] This disclosure relates to a skin care composition, in particular, a micellar cleansing composition based on a biosurfactant and a polyglycerol ester surfactant in a micellar formulation. CONTEXT OF THE INVENTION

[0002] Monophasic micellar water as a gentle makeup remover is popular with consumers because it provides hydration and a refreshing sensation after use. The problem with monophasic micellar water is that its effectiveness in removing makeup, including foundation and mascara, especially long-lasting makeup, is relatively low compared to oil-based makeup removers. Therefore, offering a micellar cleansing composition that is both aesthetically pleasing and highly effective is a challenge. Products with alternative cleansing components, including polyethylene glycol surfactants, offer an alternative to oil-based makeup removers but can be harsh on the skin.

[0003] The inventors have formulated an innovative technology that overcomes the shortcomings of the prior art to improve the performance of a micellar water cleanser by incorporating biosurfactants, for example, but not limited to, rhamnolipid, sophorolipid, spiculisporic acid, sodium surfactin, with at least one polyglycerol ester surfactant. Through the use of these ingredients, the micellar cleansing composition is free of ingredients that are harsh, undesirable, or unsustainable and offers demonstrably improved efficacy compared to less natural or more aggressive compositions. The micellar cleansing composition is transparent and maintains the clear appearance of micellar water upon application, with a refreshing sensation after use, and offers enhanced cleansing efficacy and hydration compared to current product solutions.In some embodiments, the inventive composition is free of polyethylene glycol / polyethylene oxide (PEG / POE) surfactants.

[0027] In the various embodiments, the micellar cleansing composition is a micellar water essentially free of an oil phase. In some embodiments, the micellar cleansing composition is a skin cleanser, a shampoo, or a shower gel, and in some embodiments In particular, the micellar cleansing composition is a facial cleanser and / or a makeup remover.

[0028] The inventors have proposed a monophasic micellar cleansing composition having a combination of surfactants that includes at least one biosurfactant and at least one polyglycerol ester surfactant, in particular one of the polyglycerol-3 and polyglycerol-4 ester surfactants, wherein the combination of surfactants provides a water-rinsable composition that is visually clear and pleasant to apply with a high makeup-removing capacity. More specifically, the composition offers highly effective makeup removal, surpassing the performance of at least one commercial reference having components that are considered effective but less desirable due to the presence of harsh and less natural ingredients.

[0029] The inventors have demonstrated that incorporating at least one biosurfactant and at least one polyglycerol ester surfactant into monophasic micellar water results in an unexpected and significant improvement in removal efficacy compared to the current reference composition, which includes a PEG / PEO surfactant.

[0201] Removal efficacy with polyglyceryl surfactants with / without biosurfactants

[0202] The compositions listed in Table 5 include only water and a polyglycerol ester surfactant.

[0210] As shown in Table 6, all the compositions tested, compared to COMP 1, demonstrated improved makeup removal and left less residual makeup on the testers' arms. The results demonstrate that the combinations of rhamnolipid and polyglyceryl-4 caprate, rhamnolipid with polyglyceryl-3 caprylate / caprate, and rhamnolipid with polyglyceryl-3 caprylate / caprate provide the greatest extent of makeup removal, unexpectedly demonstrating an increase of over 60% and up to over 100% in performance compared to the commercial reference.Furthermore, the results with rhamnolipid and polyglyceryl-4 caprate combined, rhamnolipid with polyglyceryl-3 caprylate / caprate, and rhamnolipid with polyglyceryl-3 caprylate / caprate demonstrate an improvement of at least 10–15% compared to the performance of each of the polyglyceryl ester surfactants used alone (polyglyceryl-4 caprate (72%) and polyglyceryl-3 caprylate / caprate (73%)). These results are also unexpected, given that the polyglyceryl-3 caprylate / caprate and polyglyceryl-4 caprate surfactants in combination with biosurfactants outperformed the other polyglycerol ester / biosurfactant combinations.The results show that it is possible to offer a micellar cleanser that provides a high makeup removal capacity, superior to the commercial reference, uses less aggressive and more durable ingredients, and promotes the solubilization of ingredients in order to give a clear, cloud-free, pleasant appearance and a sensory aesthetic to the application, which is important for consumers.

[0211] 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 being the best envisaged embodiment for carrying out this disclosure, but that the disclosure will include all embodiments falling within the scope of the appended claims. DEFINITIONS

[0212] “Cleanser” or “micellar cleansing composition” as used herein means and refer to any micellar cleansing composition used for application on a keratinous tissue for one or more of the following: skin cleansing, makeup removal and similar.

[0213] “Keratinous substrate” and “keratinous tissue” each include, but are not limited to limit, skin, hair and nails.

[0214] The term “micellar” as used in reference to the inventive micellar cleansing composition means that the micellar cleansing composition consists of an aqueous phase with micellar aggregates in a surfactant suspension and a cationic polymer that are readily suspended in the aqueous phase by shaking and that rapidly separate / phase out when the micellar cleansing composition is at rest. It should be understood that the micellar cleansing composition does not include a significant oil content and therefore does not include an oily phase. The micellar cleansing composition is shaken or agitated to obtain a suspension of the surfactants before application. Pre-application shaking forms a sufficiently uniform and stable suspension to allow uniform application to keratinous tissue for makeup removal.Furthermore, the transparency of a micellar cleansing formula indicates that all ingredients have been adequately solubilized, particularly polyglycerol ester surfactants. The micellar cleansing formula is light, somewhat like a toner, with a pleasant feel upon application.

[0215] “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 "All Natural," meaning that all carbon atoms of intentionally added ingredients come from natural sources in accordance with ISO 16128.

[0216] “Free from petrochemicals” means that petrochemicals Excluded substances have not been added as components. Some specific, but not limiting, examples of petrochemicals that are absent from the micellar cleansing composition include benzalconium chloride, isododecane, isohexadecane, and the like. In some embodiments, the micellar cleansing composition is not petrochemical-free but is formulated to have an amount of petrochemicals equal to or less than the amounts found in similar commercially available compositions.

[0217] “Silicone-free” means that the excluded silicones have not been added as that component. In some embodiments, a composition is devoid of of silicones. Some specific, but not limiting, examples of silicones that are absent from the micellar cleansing composition include, but are not limited to, silicone polymers, for example selected from dimethicone, cyclopentasiloxane and other silicone oils, and silicone elastomers.

[0218] The term “skin”, as used herein means and refers to cutaneous materials containing keratin such as the skin of the face and body, scalp, eyebrows and lips.

[0219] An inventive composition is "stable" or exhibits "stability," as these terms may be used here, if it shows no sign of significant change in one or more characteristics, including color, odor, pH, or transparency, or increased viscosity, or obvious precipitation of an ingredient, at room temperature and at temperatures in the range of approximately 25°C to approximately 45°C. In some embodiments, a micellar cleansing composition is stable at 25°C for at least one month, or at least two months, or longer.As described here, some test compositions demonstrate turbidity which may be associated with insufficient solubilization, particularly of polyglycerol ester surfactants, or with the precipitation of one or more ingredients demonstrating the instability of the micellar cleansing composition; although turbidity is not critical for efficacy, in some embodiments, compositions that are cloudy are considered less suitable due to consumer expectations regarding visual aesthetics.

[0220] The term "active substance," as used herein in relation to the percentage quantity of an ingredient or raw material, refers to 100% activity of the ingredient in the raw material, unless otherwise stated. All quantities stated herein are relative to the quantity of active substance, unless otherwise stated.

[0221] The articles "a" and "an," as used herein, mean one or more when applied to any feature in embodiments of this disclosure described in the patent memorandum and claims. The use of "a" and "an" does not limit the meaning to a single feature unless such a limitation is specifically stated. The articles "the," "a," or "them" preceding singular or plural nouns or noun phrases denote a specified particular feature or features and may have a singular or plural connotation depending on the context in which it is used. The adjectives "any" and "all" mean one, some, or all indiscriminately, regardless of quantity.

[0222] “At least one” or “one or more”, as used in this document, means one, two, three or more and thus includes individual components as well as mixtures / combinations.

[0223] The transitional terms “comprising,” “consisting essentially of,” and “consisting of,” when used in the appended claims, in their original and amended forms, define the scope of the claims with respect to any additional unmentioned elements or steps of claims that are excluded from the scope of the claim(s). The term “comprising” is intended to be inclusive or broad and does not exclude any additional, unmentioned element, process, step, or material. The term “consisting of” excludes any element, step, or material other than those specified in the claim and, in the latter case, impurities ordinarily associated with the specified material(s).The expression "essentially consisting of" limits the scope of a claim to the specified elements, steps, or material(s) and to those that do not materially affect the fundamental and innovative feature(s) of the claimed disclosure. All the materials and processes described herein that embody this disclosure may, in other embodiments, be defined more specifically by any of the transitional terms "comprising," "essentially consisting of," and "consisting of."

[0224] Apart from the examples of operation, or unless otherwise indicated, all numbers expressing quantities of ingredients and / or reaction conditions should be understood as being modified in all cases by the term "about", meaning to within 10% of the number indicated (for example, "about 10%" means 9% to 11% and "about 2%" means 1.8% to 2.2%).

[0225] All percentages and ratios are, unless otherwise stated, calculated by weight. All percentages are, unless otherwise stated, calculated relative to the total composition. In general, unless expressly stated otherwise herein, "weight" or "quantity" as used herein with respect to the percentage quantity of an ingredient refers to the quantity of raw material comprising the ingredient, the raw material being described herein as comprising less than and up to 100% of the ingredient's activity. Accordingly, the percentage by weight of an active ingredient in a composition is represented as the quantity of raw material containing the active ingredient that is used and may or may not reflect the final percentage of the active ingredient, the final percentage of the active ingredient being dependent on the percentage by weight of the active ingredient in the raw material.

[0226] All ranges and quantities indicated herein are intended to include subranges and quantities using any disclosed point as a boundary. 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 the Numbers, quantities, ranges, etc., may be modified by the term "approximately." Similarly, a given range of "approximately 1% to 10%" is understood to have its bounds of both 1% and 10% modified by the term "approximately." Furthermore, it is understood that when a quantity of a component is given, it is meant to refer to the quantity of the active ingredient, unless specifically stated otherwise. As used here, all proposed ranges are intended to include every specific range within the given ranges, and combinations of intermediate sub-ranges. Thus, a range of 1 to 5 specifically includes 1, 2, 3, 4, and 5, as well as the sub-ranges 2 to 5, 3 to 5, 2 to 3, 2 to 4, 1 to 4, etc. As used here, a report range is meant to include each specific report within subranges and a combination of subranges between the given ranges.

[0227] Although the numerical ranges and parameters presenting the general scope of the disclosure are approximations, unless otherwise indicated, the numerical values ​​presented in the specific examples are reported as accurately as possible. However, every numerical value inherently contains some error necessarily resulting from the standard deviation observed in their respective test measurements. The following example serves to illustrate embodiments of this disclosure but is not, however, limiting in nature.

[0228] As used herein, the expressions "substantially free" or "essentially free" or "excluded" mean that the specific material may be present in small quantities that do not materially affect the fundamental and innovative characteristics of the embodiments of the micellar cleansing composition according to the disclosure, or that the material may be absent. For example, there may be less than 2% by weight of a specific material added to a composition, relative to the total weight of the micellar cleansing compositions (provided that an amount less than 2% by weight does not materially affect the fundamental and innovative characteristics of the embodiments of the micellar cleansing composition according to the disclosure).Similarly, micellar cleansing compositions may include less than 2%, less than 1.5%, less than 1%, less than 0.5%, less than 0.1%, less than 0.05%, or less than 0.01%, or no amount (0%), of the specified material. Furthermore, all components positively presented in this disclosure may be negatively excluded from the claims; for example, a claimed composition may be "free," "substantially free," or "substantially free" of one or more components that are positively presented in this disclosure. The expression "substantially free" or "substantially free" as used herein may also mean that the specific material is not added to the micellar cleansing composition, but... It may, however, be present in a raw material included in the micellar cleansing composition.
