Skin care compositions containing cleansing polymers

Abstract

A skin care composition in the form of an emulsion has a continuous phase comprising a polymer and water and a dispersed phase comprising two or more emollients and emulsifiers. The polymer is an acrylate / taurine salt copolymer compatible with PEG-100 stearate, so that the composition is a stable emulsion with sufficient viscosity.

Description

Technical Field

[0001] The present disclosure generally relates to skin care lotion compositions containing cleansing polymers, and in particular to skin care lotions that are stable viscous compositions containing cleansing polymers such as acrylate, taurate copolymers. Background Art

[0002] Some consumers want skin care products to be effective, have a silky texture, absorb quickly into the skin, and be formulated with cleansing ingredients.

[0003] Polymers are frequently used in skin care products to enhance the viscosity of the product and can also act as moisturizers. Many skin care products contain a variety of polymers, which may include polyacrylamide, petroleum-derived ingredients (e.g., isoparaffins, petrolatum), and / or ethoxylated ingredients. However, some consumers prefer products that are formulated without these ingredients, and may also want products that meet the requirements to be marketed under the name "Clean at Sephora" (see Best Clean Beauty Products 2022. Sephora. Retrieved June 14, 2022 from www.sephora.com / beauty / clean-beauty-products "Clean at Sephora" is an initiative by the beauty retailer to label more than 2,000 products as "clean," which in this case means free of ingredients such as sulfates, parabens, formaldehyde, phthalates, and mineral oil.

[0004] However, it is difficult to change the thickening system in skin care products. Skin care products, such as moisturizers, are difficult to formulate, and new polymer thickening systems can be incompatible with other ingredients and can destabilize the emulsion, change viscosity (e.g., the product may become too thin or too viscous to spread easily on the user's skin), reduce efficacy, and / or change texture (e.g., the product becomes too sticky and / or gritty).

[0005] Therefore, there is a need for one or more polymeric thickeners that are clean and produce stable skin care compositions having viscosities, efficacy and textures preferred by consumers. Summary of the invention

[0006] A skin care composition comprising: (a) a continuous phase comprising: (i) a polymer comprising an acrylate / taurate copolymer; (ii) water; (b) a dispersed phase comprising: (i) two or more emollients, the two or more emollients comprising: (1) a liquid emollient; wherein the liquid emollient comprises an alkane, an ester, a triglyceride, or a combination thereof; (2) a fatty alcohol having an average carbon chain length ranging from about 12 to about 22; and (c) an emulsifier comprising PEG-100 stearate.

[0008] While the specification concludes with claims particularly pointing out and distinctly claiming the subject matter of the invention, it is believed the invention will be more readily understood from the following description taken in conjunction with the accompanying drawings, wherein:

[0010] Figure 2 is a graph showing the viscosity of skin care compositions containing an emollient containing either isohexadecene or triheptanoin and different emulsifiers.

[0011] Figure 3 The setup for the adhesive force method is shown. DETAILED DESCRIPTION

[0012] Skin care compositions may contain synthetic polymers. Polymers can enhance the texture and viscosity of the composition. However, these polymers may contain polyacrylamides, petroleum-derived ingredients, and / or ethoxylated ingredients. Some consumers prefer products that are formulated without these ingredients while also being clean.

[0013] It was found that when the copolymer of acrylates and taurate is used as a polymeric thickener in a skin care composition, consumers perceive the product as providing improved moisturization without compromising negative feel on the skin compared to current products containing sodium acrylate copolymer or polyacrylamide polymer thickeners. (See Table 1 below and accompanying text for detailed results of consumer testing in which consumers evaluated a new product containing a copolymer of acrylates and taurate and two commercially available products containing conventional polymeric thickeners).

[0014] Copolymers of acrylates and taurates useful in consumer preferred cleansing skin care compositions may include, for example, Figure 1 Sodium Acrylate / Sodium Acryloyldimethyl Taurate Copolymer as shown, such as Sodium Acrylate / Sodium Acryloyldimethyl Taurate Copolymer & C15-19 Alkane & Polyglyceryl-6 Laurate & Polyglyceryl-6 (can be SEPILIFE TM NUDE is commercially available from Seppic), and / or Sodium Acrylate / Sodium Acryloyldimethyl Taurate Copolymer & C15-19 Alkane & Lauryl Glucoside (available from Natursol TM EMI132 from SNF TM Commercially available).

[0015] In skin care compositions, polymers are typically provided in oil and then converted to become part of the continuous phase in an oil-in-water emulsion. It can be difficult to form a stable emulsion, especially if the skin care product is a moisturizer with a relatively high oil content. Emulsifiers can facilitate the formation of the emulsion and can also help maintain product stability.

[0016] However, it is difficult to select one or more emulsifiers to effectively increase the viscosity of the composition and form a stable emulsion in products containing acrylate and taurate copolymers.

[0017] In addition, it may be advantageous that one or more emulsifiers are effective because emulsifiers are generally used at the lowest level that provides the desired product viscosity and stability to obtain optimal product performance. If the emulsifier is only effective when used at relatively high levels, the product may be difficult to spread and may remain on top of the skin as a white layer rather than being absorbed into the skin. In these cases, the product may also feel heavy and / or sticky. In addition, it may be advantageous if there is a synergistic effect between the polymer and the emulsifier, which may allow the emulsifier to be incorporated at even lower levels, thereby producing a smooth, lightweight moisturizer with sufficient viscosity.

[0018] Skin care compositions may include a range of emollients that soften, moisturize and / or protect the skin from irritation, as well as aid in the solubilization of various skin care benefit ingredients. These emollients may have a range of polarities, and regardless of the polarity of the emollient, it may be advantageous to select an emulsifier that is effective in the skin composition system.

[0019] Examples AJ (see Tables 1 to 3 below) are sodium acrylate / sodium acryloyldimethyl taurate copolymer & C15-19 alkane & lauryl glucoside (available from Natursol TM EMI132 from SNF TM Examples of skin care compositions with various emulsifiers (commercially available) and various emulsifiers. Examples A-1 and A-2 include PEG-100 stearate as an emulsifier and have sufficient viscosity for both emollients (1082 Pa*s and 842 Pa*s, respectively). This indicates that the PEG-100 stearate emulsifier is compatible with the sodium acrylate / sodium acryloyldimethyl taurate copolymer.

[0020] These embodiments are compared with embodiments A-1 and 2 (see Table 1 below) including PEG-100 stearate as an emulsifier, which is currently used in some commercial products. Embodiments A-1 and 2 have sufficient viscosity (respectively 1082Pa*s and 842Pa*s), which indicates that the emulsifier is compatible with sodium acrylate / sodium acryloyldimethyl taurate copolymer. Adhesion generally refers to the peak force required for separating an object from the composition after contacting the composition. At least some users associate good moisturizing with high adhesion, especially during and / or shortly after application of the product (e.g., less than 10, 9, 8, 7, 6, 5, 4, 3, 2 or even less than 1 minute after application). However, the increase in adhesion is usually accompanied by an increase in viscosity, and the moisturizer feels heavy on the top of the user's skin. Although the user can tolerate or even expect to have some stickiness and / or heaviness as a signal of moisturizing during and / or after application, it may not be expected that stickiness will continue for example more than 1, 5, 7, 10 or even more than 20 minutes after application of the product.

[0021] According to the Adhesion Method described herein, the composition may have an average adhesion of less than 800 g between 20 minutes and 40 minutes, and alternatively less than 790 g. In some examples, the composition may be free of silicone.

[0022] The skin care composition can be a physically stable emulsion. The composition is physically stable if there is no phase separation or less than a 40% change in viscosity by visual inspection when stored in a finger-tightly closed glass jar between t=0 (i.e., immediately after preparation of the composition) and between freeze-thaw cycles, wherein the sample is kept at -18°C for 24 hours and then returned to room temperature, or stored at 40°C for one month and then returned to room temperature. As used herein, "visual inspection" means that a human observer can visually discern with the naked eye (except for standard corrective lenses suitable for correcting myopia, hyperopia or astigmatism or other corrective vision) whether the product separates into 2 distinct layers in a 2 ounce clear glass jar under lighting at least equal to the illumination of a standard 100-watt incandescent bulb at 30 cm.

[0023] Unless otherwise specifically stated, all percentages are by weight of the cosmetic composition. Unless otherwise specifically stated, all ratios are by weight. All ranges are inclusive and combinable. The number of significant figures expresses neither a limitation on the amount shown nor a limitation on the accuracy of the measurement. All numerical values ​​should be understood to be modified by the word "about", unless otherwise specifically stated. Unless otherwise stated, all measurements are understood to be made at approximately 25°C and ambient conditions, where "ambient conditions" means conditions at about 1 atmosphere and about 50% relative humidity. All numerical ranges are narrower ranges including the end values; the upper and lower limits of the ranges described are interchangeable to further form ranges that are not explicitly described.

[0091] In some examples, the composition can be formulated to be free, substantially free, or free of dye.

[0092] How to use

[0093] Skin care cream / moisturizer composition can be applied to face, neck and / or their part or combination at least once a day, twice a day or on a more frequent basis every day during the treatment cycle. When applied twice a day, the first and second applications are separated by at least 1 to 12 hours. Usually, the composition is applied in the morning and / or before going to bed at night. The treatment cycle herein is ideally the time when the skin care active substance is enough to improve the appearance of the skin. The treatment cycle can last for at least one week (for example, about 1 week, about 2 weeks, about 4 weeks, about 8 weeks or even about 12 weeks). In some cases, the treatment cycle will be extended for multiple months (i.e., about 3 months to 12 months). In some cases, the composition can be applied most of the time in a week (for example, at least 4 days, 5 days or 6 days per week), at least once a day or even twice a day during the treatment period of at least 2 weeks, 4 weeks, 8 weeks or 12 weeks.

[0094] The skin care composition may be intended for use before bedtime and / or in the morning. It may be massaged evenly over the entire face (including or excluding the eye area) and / or neck. The product may be the last step in a skin care routine and may be applied after cleansing and optionally after application of serums and / or other skin care products. The skin care composition may hydrate to visibly firmer skin for an enhanced appearance. The skin composition may strengthen the skin's moisture barrier, making the skin elastic, firm and younger looking. The skin care composition may reduce and / or soften wrinkles and fine lines.

[0095] Test Method

[0096] Adhesion method

[0097] The method provides a suitable means for determining the viscosity of the compositions described herein. The method uses a texture analyzer to contact a probe with a film formed by the composition. The texture analyzer then measures the force required to separate the probe from the composition film. Adhesion can be measured in this way. The adhesion method is configured to run for 100 minutes. Without being limited by theory, it is believed that the adhesion properties exhibited by the composition during the adhesion test are similar to the adhesion properties exhibited by the composition within the first few minutes (e.g., less than 10 minutes, between 30 seconds and 5 minutes, or between 1 minute and 3 minutes) of the user using the composition.

[0098] Figure 3 An exemplary test apparatus for adhesion testing is shown. A TA.XT2i brand texture analyzer (available from Texture Technologies Corporation, MA) 50 or equivalent is used to measure the adhesion of a film formed from a composition of interest. The texture analyzer is equipped with an adhesion probe 52 in the form of a 12.75 mm diameter acrylic cylinder having a flat surface. During the test, the flat surface of the probe 52 is brought into contact with the surface of the film of the composition. Therefore, the flat surface of the probe and the surface of the film must be parallel to each other during the test to ensure that the film has sufficient contact over the entire effective test surface of the probe 52. The film is prepared by filling or overfilling a rectangular channel 54 (e.g., 25 cm long × 30 mm wide × 0.25 mm deep) with the composition to be tested (and then pulling it down).

[0099] Adhesive test scheme is used to test with the pre-test speed of 0.10mm / s, the test speed of 0.10mm / s and the post-test speed of 1.0mm / s. The force applied is 200g, the return distance is 4mm, and the contact time is 5.0s. The trigger type of the designated sample contact is set to automatic, and the trigger force is 5.0g. The test is run and immediately after the film is prepared, it is run with the following time increments: <1 minute (that is, immediately after the film is prepared), 10 minutes, 20 minutes, 30 minutes, 40 minutes, 50 minutes, 60 minutes, 80 minutes and 100 minutes. Each time point is run on the previously undisturbed / untested area of ​​the sample. Each sample is run in parallel three times, and the average value is recorded.

[0100] The average tack between 20 minutes and 40 minutes can be used to determine if the product is too sticky to be accepted by consumers. To calculate the average tack between 20 minutes and 40 minutes, add the tack at 20 minutes, 30 minutes, and 40 minutes and divide by 3 and report in grams (g).

[0101] Rheological test methods

[0102] This method provides a suitable means for measuring the viscosity of the compositions herein. The instrument used in this method is a TA Instruments brand rheometer or equivalent. The instrument is set up to perform a rotating ramp under controlled stress conditions, from 0.01 Pa to 2000 Pa in 240 seconds, using serrated parallel plates of 40 mm diameter and 1.0 mm gap for the upper and lower geometries. The temperature is set to 25°C. The instrument protocol is set to collect 100 data points per decade of logarithmic distribution, with the shear rate exceeding 110s -1 Set to stop measuring.

[0103] After performing the automatic gap calibration, approximately 5 grams of sample are placed in the center of the plate. The plate is positioned to provide a gap of 1.05 mm, and any excess material extruded from the peripheral gap of the parallel plates is carefully trimmed. The plate is then moved the last 0.05 mm to provide a gap of 1.00 mm, and the measurement is started. At the end of the run, the data file is saved for subsequent plotting and analysis. Viscosity is reported in Pascal-seconds (PaS) for a shear rate of 0.10 s -1 or close to 0.10s -1 The value at time.

[0104] Example

[0105] The following data and examples are provided to help illustrate the skin care compositions described herein. The exemplified compositions are given for illustrative purposes only and should not be construed as limitations of the present disclosure, as many variations are possible without departing from the spirit and scope of the present disclosure. Unless otherwise indicated, all parts, percentages and ratios herein are by weight.

[0106] Table 1 below shows the results of the consumer test. In this test, each consumer applied one of the three products to their face at least once a day for two weeks. They then rated the product as poor (0), fair (25), good (50), very good (75), or excellent (100) in ten categories, as shown in Table 1. The total score was then divided by the total number of consumers who used the product to determine the average score for each category.

[0107] Table 1 shows that Example 43 with cleansing polymers (sodium acrylates / sodium acryloyldimethyl taurate copolymer & C15-19 alkane & polyglyceryl-6 laurate & polyglyceryl-6) performed statistically better than the control products with sodium acrylates copolymer or polyacrylamide on categories related to moisture perception (e.g., keeps skin feeling moisturized, hydrated, moisturized all day, and does not make my skin feel dry or tight). Good. Table 1 also shows that Example 43 with the cleansing polymer performs no worse than the control product with respect to categories related to feel (e.g., does not make the skin feel greasy or sticky / tacky, does not make the skin look greasy or shiny, absorbs quickly, and does not leave an unpleasant residue). This is interesting because polymers that give consumers a more hydration perception typically create a negative tradeoff in how the user's skin feels. However, no such tradeoff is seen with the copolymer of acrylate and taurate polymer thickeners.

[0112] *Statistically superior to control

[0113] The examples detailed in Tables 2 to 15 below are prepared by the following method. First, an aqueous phase is prepared by mixing water and water-soluble ingredients, including, but not limited to, glycerin, chelating agents (e.g., disodium ethylenediaminetetraacetate, EDDS), water-soluble skin care actives (e.g., panthenol), and antioxidants (e.g., hydroxyacetophenone). The aqueous phase is mixed and heated to about 50° C. until the ingredients are dissolved and / or dispersed. The aqueous phase may contain from about 70% to about 98%, alternatively from about 75% to about 95%, alternatively from about 80% to about 94%, alternatively from about 85% to about 93%, or alternatively from about 88% to about 92% water, by weight of the aqueous phase.

[0114] In a second container, prepare an oil phase premix. The premix includes liquid and waxy emollients and one or more emulsifiers (eg, PEG-100 stearate). The premix is ​​mixed and heated to about 50°C until the ingredients are fully dispersed in the premix.

[0115] The premix is ​​added to the water phase. The mixture is then ground to emulsify the oil phase premix into the water phase to form an emulsion in which the water phase is the continuous phase and the oil phase is the dispersed phase. One or more additional ingredients are added after emulsification while continuously mixing with an overhead mixer. Additional ingredients, including but not limited to polymeric thickeners (e.g., SEPILIFE TM NUDE), silicones, colorants, pigments, powders, mica, preservatives, fragrances and additional skin actives.

[0116] The viscosities of the examples in the table below were determined using the Rheology Test Method as disclosed herein.

[0117] For Tables 2 to 4 below and Figure 2 In the embodiments detailed in , various emulsifiers were tested in skin care compositions including sodium acrylate / sodium acryloyldimethyl taurate copolymer and other ingredients. Each emulsifier was tested in a composition containing an emollient including isohexadecane (a non-polar hydrocarbon oil) or triheptanoin (a triglyceride with greater polarity than isohexadecane). If the emulsifier helps to form sufficient viscosity, as indicated by the rheological test method described herein, such as when the composition has a viscosity greater than or equal to 550Pa*s, preferably greater than 850Pa*s, the emulsifier may be acceptable to consumers. This viscosity is considered to be the minimum necessary to produce an acceptable composition that can be packaged in a can that is opened during consumer use. Compositions with higher viscosities may be more popular with consumers, and in some embodiments, the viscosity can be increased by adding more emulsifiers and / or polymers. It is preferred to select an emulsifier that produces a composition containing isohexadecene and triheptanol emollients of sufficient viscosity because this shows that the emulsifier develops viscosity in a range of products having different emollient polarities. In addition, many skin care products use more than one emollient of different polarities to help solubilize various skin care benefit ingredients, including ingredients that improve skin texture, tone, or protect against UV damage.

[0118] Some embodiments are made with modified corn starch, and other embodiments are made with maize corn starch (which may be HTP Pure Commercially available). It was found that there was no significant difference in viscosity and stability when formulated with either starch. It was found that in some large-scale production, maize corn starch may be preferred.

[0141] Examples where the viscosity of both emollients is greater than or equal to 550 Pa*s are Examples A, E, G and H.

[0142] Examples E-1 and 2 are not preferred because both examples have a significant malodor that would be objectionable to many consumers.

[0143] Example G-1 may be acceptable to consumers. However, Example G-2 is noticeably tacky, which makes the product difficult to spread on the user's skin, and the product may feel heavy and sticky after application. Since this emulsifier does not produce a consumer-friendly product in a range of emollients, it may not be preferred.

[0144] Examples H-1 and 2 both have a viscosity greater than or equal to 550 Pa*s, and have no noticeable unpleasant odor, and are acceptable to consumers.

[0145] Some consumers may prefer Examples A-1 and A-2 which include PEG-100 stearate emulsifier. These compositions have higher viscosities than H-1 and H-2, do not feel sticky, and also have no noticeable odor.

[0146] The skin care composition examples in Tables 5-15 were prepared and are believed to be stable, have adequate viscosity, and be acceptable to consumers.
