Description

[Technical Field]

[0001] Priority This application claims priority to U.S. Provisional Patent Application No. 63 / 505,203, filed on 31 May 2023, which is incorporated herein by reference in its entirety.

[0002] This disclosure relates, in general terms, to cosmetic compositions, such as water-in-oil cosmetic compositions. [Overview of the Initiative]

[0003] According to one embodiment, the water-in-oil emulsified cosmetic composition comprises (a) at least one polyglycerol-type surfactant; (b) a resin; (c) a solvent comprising at least one polar oil and at least one non-polar oil; and (d) water. [Brief explanation of the drawing]

[0004] [Figure 1] Figure 1 is a plot comparing the average evaluation scores of the composition of Example 1 (left column) and a commercially available composition (right column). [Modes for carrying out the invention]

[0005] Unless otherwise specified, "a" or "an" means one or more.

[0006] When used herein, the term “about” preceding a specific number may mean ±20% of the number; ±18% of the number; ±15% of the number; ±12% of the number; ±8% of the number; ±5% of the number; ±3% of the number; ±2% of the number; ±1% of the number; or ±0.5% of the number.

[0007] All content information regarding the components of a composition, expressed as a percentage (%), refers to a mass percentage (%) of the total mass of the composition, unless otherwise specified.

[0008] As used herein, the expression "water-in-oil composition" and related expressions refer to an emulsified composition of the water-in-oil type in which an aqueous (water) phase is dispersed in an oil phase.

[0009] As used herein, the expression “microplastic particles” means particles containing a solid polymer, which may contain additives or other substances, and wherein ≥1% w / w of the particles have (i) an overall dimension of 0.1 μm ≤ x ≤ 5 mm, or (ii) with respect to fibers, a length of 0.3 μm ≤ x ≤ 15 mm and a length-to-diameter ratio of >3.

[0010] The expression "particles containing solid polymer" refers to either (i) particles of any composition having a continuous solid polymer surface coating of any thickness, or (ii) particles of any composition having a solid polymer content of ≥1% w / w.

[0011] The 1,4-dioxane and ethylene oxide impurities in polyethylene glycol (PEG)-containing surfactants may raise concerns about meeting the "clean beauty" requirements, such as safety, non-toxicity, and transparency, when labeling cosmetics.

[0012] Some consumers also have environmental concerns regarding the low biodegradability of silicones. Many water-in-oil emulsified cosmetics use PEG-containing surfactants, silicone-containing surfactants, and / or silicone solvents, such as bentonite-gel systems containing silicone oils, such as cyclomethicone (D5) and dimethicone. Eliminating PEG-containing surfactants, silicone-containing surfactants, and / or silicone solvents can often negatively impact the stability and / or sensory properties of the cosmetic.

[0013] Furthermore, many water-in-oil cosmetic compositions may have these oil phases separated over time, so they need to be shaken before use. In addition, the color of stored water-in-oil cosmetics may change due to pigment migration and aggregation within the product.

[0014] This disclosure provides an emulsified water-in-oil composition that may have improved stability. Specifically, the composition may avoid oil phase separation at room temperature and / or at high temperatures such as 37°C, 45°C, or 50°C and / or at low temperatures such as 0°C or -5°C for a period of at least one week, or at least two weeks, or at least three weeks, or at least four weeks.

[0015] This composition can also avoid color changes caused by pigment migration. This composition can maintain sensory values, such as creaminess and ease of application. In many embodiments, this composition does not need to contain PEG surfactants. In many embodiments, this composition may contain PEG-based components.

[0016] The composition may be a long-wear composition. As used herein, the term “long-wear” means that the composition can be worn for at least 4 hours to a maximum of 24 hours, or at least 6 hours to a maximum of 24 hours, or at least 8 hours to a maximum of 24 hours, or at least 10 hours to a maximum of 24 hours, or at least 12 hours to a maximum of 24 hours, or at least 14 hours, or at least 16 hours, or at least 18 hours without interruption of its aesthetic appearance. Without being limited by any theory, the long-wear effect of the composition may be imparted by a combination of (a) one or more film-forming agents, e.g., MQ resins, e.g., silicone resins which may be trimethylsiloxysilicate; and / or natural resins, e.g., rosinates, e.g., hydrogenated glyceryl rosinate, or resinous fatty acid esters, e.g., fatty acid esters which may be dextrin isostearate; and (b) a combination of thickeners, e.g., bentone gel, e.g., at least one hydrophobic mineral gelling agent.

[0017] This composition can be in a creamy form and impart a smooth, natural finish and / or bleeding. Without being limited by any theory, such effect(s) of the composition can be imparted by a treated powder in the composition, for example, a stearic acid-treated powder, for example, titanium dioxide powder treated with stearic acid.

[0018] This composition can have a lightweight texture with a silky feel. Without being limited by any theory, such property(ies) can be imparted by an oil phase which may be a non-silicone volatile oil phase of the composition.

[0019] In some embodiments, the composition may not contain a silicone solvent(s), for example, cyclomethicone (D5) and dimethicone. In many embodiments, the composition may not contain a silicone surfactant(s), for example, a dimethicone-containing surfactant(s). In many embodiments, the composition may not contain a silicone emulsifier(s).

[0020] In some embodiments, this composition may not contain a synthetic polymer.

[0021] In some embodiments, this composition may not contain any polyethylene glycol-containing component, for example, a PEG-containing surfactant, any polymeric component, for example, (meth)acrylate or (meth)acrylamide; and / or, with the exception of silicone resin, any silicone, for example, a silicone solvent and a silicone surfactant.

[0022] In some embodiments, the water-in-oil emulsified composition of the present disclosure may contain (a) at least one polyglycerol type surfactant; (b) a film-forming agent, for example, a resin which may be a natural resin and / or a silicone resin; (c) a solvent containing at least one polar oil and at least one non-polar oil; and (d) water.

[0139] The comparison was conducted by a panel including five members. The panelists compared the two compositions in terms of application, attachment, and texture using the following protocol:

[0140] the purpose: The objective of this study was to determine the differences in application, wearability, and tactile characteristics, as well as overall consumer appeal, between Foundation A and Foundation B, using a panel of five female volunteers. Participants were asked to complete a questionnaire after wearing each supplied product for a full day.

[0141] Test procedure: This study was designed as a two-day study in which each test subject used the test product according to the instructions provided: Instructions for Use: In the morning, apply the provided foundation to your face in place of your usual foundation, using your preferred foundation application method. Do not use any other new makeup products during this time. Apply until you achieve a full coverage finish. Wear the foundation all day, then complete the provided Microsoft Forms questionnaire.

[0142] The questionnaire consisted of several questions asking participants to rate certain characteristics of the test foundations based on a specific scale, open-ended like / dislike questions, and their selection of which test foundation they preferred. Survey scale: Coverage scale: 0 = Low coverage 10 = High coverage Scale of attachment: 0 = disappeared immediately 10 = Lasted all day Applicable scale: 0 = Not easy to apply 10 = Lasted all day Build capability scale: 0 = Not buildable 10 = Very buildable Tactile scale: 0 = feels heavy 10 = Feels light

[0143] The results of the comparison are shown in Table 3 and Figure 3.

[0144] [Table 3]

[0145] One day after application, participants were asked to complete a sponsor-provided questionnaire regarding the characteristics and overall preference of Foundation A and Foundation B. Using questions scaled from 0 to 10, the survey obtained ratings for parameters such as wearability, applicability / creaminess texture, buildability (the ability of the foundation to apply well over itself to achieve better coverage), and perceived weight. Panelists rated Foundation A higher than Foundation B in the areas of sustained wearability, creaminess and ease of application, ability to build over itself, and lightweight feel.

[0146] Conclusion: Regarding application, the panelists gave Foundation A an average score of 9.2 / 10 and Foundation B an average score of 8.4 / 10.

[0147] Regarding application / creaminess, the panelists gave Foundation A an average score of 9.4 / 10 and Foundation B an average score of 8.0 / 10.

[0148] Regarding buildability, the panelists gave Foundation A an average score of 8.8 / 10 and Foundation B an average score of 8.4 / 10.

[0149] Regarding the feel, the panelists gave Foundation A an average score of 9.2 / 10 and Foundation B an average score of 6.8 / 10.

[0150] At the end of the second survey, the panelists were asked which foundation they preferred to wear. 80% of the panelists preferred Foundation A over Foundation B.

[0151] Table 4 provides compositions for Example 2, which contains a silicone resin but does not contain a silicone surfactant, and Example 3, which contains a natural resin(s) but does not contain a silicone resin or silicone surfactant. Example 2 is the same as the examples in Table 1, but uses a different pigment. Example 3 uses a natural resin(s) instead of the silicone resin in Examples 1 and 2. Examples 2 and 3 are prepared using the same procedure as the compositions prepared in Table 1.

[0152] [Table 4-1] [Table 4-2] [Table 5]

[0153] Table 5 provides safety data for the compositions of Examples 2 and 3 from Table 4. The data in Table 5 demonstrates that the compositions of Examples 2 and 3 have comparable stability, as the emulsion of Example 3 showed -1 after weeks 3 and 4 at 45°C, 50°C, 0°C, and -5°C, but there was no pigment aggregation. ***
