Detailed Implementation

[0014] Unless otherwise stated, "a" or "an" refers to one or more.

[0015] As used herein, the term “approximately” preceding a specific value may mean ±20% of that value; ±18% of that value; ±15% of that value; ±12% of that value; ±8% of that value; ±5% of that value; ±3% of that value; ±2% of that value; ±1% of that value; or ±0.5% of that value.

[0016] Unless otherwise stated, all content information of the composition components expressed as percentages (%) refers to the percentage by mass (%) relative to the total mass of the composition.

[0017] Consumers generally prefer high SPF mineral sunscreens over organic sunscreens due to their advantages over organic sunscreens, such as broad-spectrum protection, safety, less skin irritation or allergic reactions compared to organic sunscreens, environmental friendliness, and photostability. However, a challenge with mineral sunscreens can be that when loaded with high amounts of mineral particles, they often leave a white cast on the skin, may be difficult to spread evenly, and leave a greasy and / or sticky feeling. The inventors of this invention have discovered that oil-based cosmetic compositions that are anhydrous or have a low water content (e.g., no more than 30%) can be loaded with high amounts of mineral particles, such as ZnO and / or TiO2 particles, thus providing a high level of sun protection while being easy to spread, non-greasy, and without leaving a noticeable white cast on the skin upon application.

[0018] According to one embodiment, the cosmetic composition may include (a) at least one oil; (b) a lithium montmorillonite thickener; (c) cellulose; and (d) one or more ultraviolet-scattering powders selected from zinc oxide, titanium dioxide, and mixtures thereof. At least some particles of the one or more ultraviolet-scattering powders may be made of poly[C8-C 20 [Hydroxycarboxylic acid] treatment. The amount of at least one oil in the composition may not exceed 50% by mass. The amount of water in the composition may not exceed 30% by mass.

[0019] In some implementations, the cosmetic composition can be used for sun protection, i.e., sunscreen cosmetics. Sunscreen cosmetics may have a sun protection factor (SPF). The SPF of a sunscreen product represents the sun protection factor, which is a relative measure of the amount of time that a sunscreen agent provides protection against ultraviolet (UV) radiation. UVB rays primarily affect the outer layer of the skin, the epidermis. They are the cause of sunburn and some superficial skin cancers. The sun also emits UVA rays, which can penetrate the layer of skin below the dermis. UVA rays are commonly associated with “tanning.” SPF values ​​only pertain to UVB rays, but sunscreen agents can also protect against UVA. If a sunscreen agent protects against both UVA and UVB radiation, it is labeled as a “broad-spectrum” sunscreen.

[0020] In some embodiments, the cosmetic composition may have an SPF of at least 10, at least 20, at least 30, at least 40, or at least 50.

[0021] Cosmetic compositions may have low viscosity, such as not greater than 6000 cps, not greater than 5500 cps, or not greater than 5000 cps, or not greater than 4000 cps, or not greater than 3000 cps. In some embodiments, the viscosity may be from 300 cps to 6000 cps, or from 400 cps to 5500 cps, or from 500 cps to 5000 cps. As used herein, the term "viscosity" generally refers to low shear viscosity, such as at 10 s⁻¹. -1 Or viscosity at a lower shear rate, or even zero shear viscosity. Low viscosity allows for easy and rapid spreading when the composition is applied to keratin surfaces such as skin or lips.

[0022] The cosmetic composition may have a pleasant texture and overall sensory properties. In some embodiments, the cosmetic composition may have a pink to pale pink lotion-like appearance and texture. The cosmetic composition can be easily spread on the skin, providing a smooth, lightweight feel and a quick-drying after-effect. In some embodiments, the cosmetic composition may leave the skin with a natural shine and glow after application, without noticeable whitening or oiliness.

[0023] When applied to keratin surfaces such as skin or lips, this cosmetic composition may provide only low or high whiteness.

[0024] When applied to keratin surfaces such as skin or lips, the cosmetic composition can be transparent.

[0025] In some embodiments, the cosmetic composition can be used alone. In other words, the composition can be applied alone to the keratin surface or substrate, such as skin, of a subject (e.g., a person) without another composition. However, in some embodiments, the cosmetic composition can be used in conjunction with another composition, which can be, for example, a cosmetic or skincare composition, such as a makeup composition or another skincare product. For example, in some embodiments, the cosmetic composition can be applied to the keratin surface before or after the application of another composition.

[0026] water

[0027] In some embodiments, the cosmetic composition may be an anhydrous composition that is completely free of water.

[0028] In some further embodiments, the cosmetic composition may contain water in amounts not greater than or less than 30%, not greater than or less than 25%, not greater than or less than 20%, not greater than or less than 15%, not greater than or less than 10%, not greater than or less than 5%, and not greater than or less than 4.5%. For example, in some embodiments, the cosmetic composition may contain water in amounts of 0.0001% to 30%, or 0.0001% to 10%, or 0.1% to 30%, 0.1% to 25%, 0.1% to 20%, or 0.1% to 15%, 0.1% to 10%, 0.1% to 5%, 0.1% to 4.5%, 0.3% to 5%; 0.5% to 5%, 1% to 5%, 2% to 5%, 3% to 5%, or 4% to 5%, or any value or subrange within these ranges.

[0030] The at least one oil may include at least one polar oil, at least one non-polar oil, or a combination of at least one polar oil and at least one non-polar oil. The amount of the at least one oil in the composition may vary. In some embodiments, the amount of the at least one oil in the composition may be up to 60%, such as 15% to 60% by mass, or 15% to 50% by mass, or 30% to 50% by mass, or 15% to 40% by mass, or 18% to 35% by mass, or 20% to 30% by mass, or any value or subrange within these ranges.

The components of oil phase A can be homogenized using, for example, a mixer at a mixing rate (e.g., 4-5 K rpm).

[0115] Lithium montmorillonite petroleum thickener can be added to the mixed oil phase A. This mixture can be homogenized using a mixer at a homogenization rate (e.g., 7-9 K rpm). Additional components of oil phase B, such as sensory modifiers and pigments, can be added to the homogenized mixture. The resulting mixture can then be blended at a mixing rate.

[0116] A wetting agent, such as ethylhexyl palmitate, can then be added to the mixture. Ultraviolet scattering particles can be added to the mixture. In some embodiments, zinc oxide particles can be added first, followed by titanium dioxide. The mixture can be homogenized uniformly using a mixer at a homogenization rate such as 7-9 K RPM, resulting in a mixture containing components of oil phases A, B, and C.

[0117] Aqueous phase D can be prepared in a separate container. Aqueous phase D can be prepared in multiple stages. For example, a mixture of moisturizers (such as glycerin) and additional ingredients (such as extracts, such as silymarin) can be prepared, and a separate mixture of water and other additional ingredients (such as other extracts, such as astabio and zemea) can be prepared. These two mixtures can then be combined.

[0118] After preparing phase D in a separate container, it can be added to the original container containing a mixture of oil phases A, B, and C. The resulting mixture can be homogenized. The resulting mixture can be cooled and degassed using a vacuum pump.

[0119] The implementation schemes described herein are further illustrated by the following operational examples, but are in any way limited to the following operational examples.

[0120] Example

[0121] Table 1 provides the ingredients of an exemplary composition.

[0122]

[0123] The compositions in Table 1 are prepared according to the following procedure: 1. Pre-weigh all components, then mix the components of phase A uniformly at 4-5K RPM.

[0124] 2. Add the Bentone gel to the components of phase A while mixing uniformly at 4-5 K RPM. Homogenize the mixture at 8 K RPM for 1 minute, then restore the mixing rate to 4-5 K RPM. Add the remaining components of phase B and mix uniformly at 4-5 K RPM.

[0125] 3. While dispersing the mixture at 4-5 K RPM, add the wetting agent. Change the mixing rate to 6-8 K RPM, then add zinc oxide particles, followed by titanium dioxide particles, and homogenize the mixture at 8 K RPM for 1 minute.

[0126] 4. Phase D was prepared separately in two parts: (a) Silymarin was dissolved in glycerol and thoroughly mixed at 500 to 700 RPM using a propeller mixer, and then the remaining components of Phase D except for water, astabio and zemea were added; (b) astabio was dissolved in water and then zemea was added; the resulting product was thoroughly mixed at 500-700 RPM using a propeller mixer until homogeneous.

[0127] 5. Mix the two mixtures of phase D using a propeller mixer at 500-700 RPM for 10-15 minutes to ensure thorough mixing. Then, mix all components of phase D separately with phases A, B, and C in another container.

[0128] 6. Add the mixed phase D to the previously prepared mixture of phases A, B, and C to form the final mixture, and homogenize it at 8 K RPM for 1 minute. Cool the homogenized final mixture and degas it using a vacuum pump.

[0129] Figure 1A -B shows photographs of the composition in Table 1 before (A) and after (B) shaking. Shaking makes the composition more homogeneous. Figure 1A The image shows that the emulsion separated before shaking, and Figure 1B The results show that the emulsion is uniformly homogeneous after shaking. The compositions in Table 1 are products of thorough shaking (mixing & shaking).

[0130] Figure 2 This is a table providing the ingredients for many cosmetic compositions. The ingredients include zinc oxide with different surface treatments, Bentone thickeners, and oil sensory modifiers. Figure 2 Various compositions with many variations are provided, such as changing the mass percentage of existing raw materials based on Table 1 and / or adding additional materials. Figure 2 The total oil phase in the table consists of phases A, B, and C. The following is given... Figure 2 The table lists exemplary components of the phases of the compositions.

[0131] Phase A (oil phase): Permethyl 99A, Cetiol Ultimate, Squalane, and RA-G 308 are nonpolar moisturizing oils, therefore they are considered "oils". - Jojoba oil: The external phase is jojoba oil, and it is also considered a polar oil in the oil phase. It is treated as an "oil". - Softisan 649 – Film-forming agent for the oil phase - DL-alpha tocopherol, ESP organic green tea oil, virgin raspberry oil, All-Q Coenzyme Q10 plus, and vitamin E acetate are all considered to be active oil components.

[0132] Sy-Glyster CRS75 is an oil-phase W / O emulsifier and dispersant.

[0133] Phase B (oil phase): - Bentone Gel TNV: A suspending agent / thickening agent for the oil phase. Celluflo C-25: A sensory modifier for the oil phase. - Mica ST(FE): Sensory modifier for the oil phase Unipure Red LLC: Red pigments for oil phase applications Phase C (oil phase) - Salacos P8: A wetting / skinning agent used to disperse pigments in the oil phase. It is considered an "oil". - Super Zinc Sheer Natural: Non-nano-hydrophobic zinc oxide UV-scattering filter to provide highly broad-spectrum sun protection and low-level whitening on the skin. - ST485SA: Nano-hydrophobic treated titanium dioxide UV scattering filter to provide high SPF and low white residue on skin. Phase D (water phase) - Deionized water: The internal phase is water. - Glycerin: A humectant used in the aqueous phase. - Phenoxetol: A preservative used in aqueous phases. - Zemea: P is used as a corrosion inhibitor and synergist in aqueous phases. - Astaplankton G8, silymarin, Astabio AP1 and Viniderm: Additional ingredients: Water-active extract components for the aqueous phase Figure 3This is a graph showing the Hunter Whiteness Index (Hunter Lab) vs. in vitro UVB absorbance measured using a Hitachi spectrophotometer for many samples. The whiteness index (Hunter Lab) properties of the mineral sunscreen samples were analyzed using an XRite spectrophotometer, and the in vitro UVB absorbance was analyzed using a Hitachi spectrophotometer. Compared to control samples #2-#7, samples #1-#14 and #19-#20 provided higher in vitro UVB absorbance and lower whiteness indices. Samples #1-#14 and #19-#20 provided lower whiteness indices than control samples #1-#7, while samples #15-#18 had higher in vitro UVB absorbance than control sample #1. Based on... Figure 3 The data shows that adding more ZnO and TiO2 by mass percentage improves the whiteness index (the whiteness on the skin) and the in vitro UVB absorbance (sunscreen factor).

[0134] Figure 4 This is a graph showing the bulk viscosity vs. in vitro UVB absorbance of many samples as measured by a Hitachi spectrophotometer. The bulk viscosity properties of the mineral sunscreen samples were analyzed using a Brookfield viscometer, and the in vitro UVB absorbance was analyzed using a Hitachi spectrophotometer. Compared to control samples #2, #3, and #4, most sunscreen samples exhibited viscosity values ​​less than ~5000 cps, confirming easy spreadability / light feel on the skin while maintaining a high SPF value.

[0135] Figure 5 This is a graph showing the in vitro absorbance (Sun Protection Factor (SPF)) of many samples measured by a Labsphere UV2000s spectrophotometer vs. the in vitro UVB absorbance measured by a Hitachi spectrophotometer. The in vitro SPF values ​​and in vitro UVB absorbance of the samples were analyzed using Hitachi vs. Labsphere UV2000s spectrophotometers. An approximately linear correlation was observed between the two instruments used to measure sun protection (290–320 nm). The Labsphere has a pre-built algorithm that calculates the in vitro SPF (Sun Protection Factor against UVB radiation in the 290–320 nm range) and the in vitro UVA Protection Factor (Protection against UVA radiation in the 320–400 nm range). A specific dose of sunscreen was applied to a plastic PMMA HD6 substrate by each sample prototype & competitor benchmark. UV radiation was then applied to the substrate with each sunscreen sample having the applied dose to measure and simulate a real-world scenario of sunburn on human skin. UVB absorbance is another indicator of the SPF value of sunscreens, measured using a Labsphere or Hitachi spectrophotometer. Higher UVB absorbance results in higher sun protection, and vice versa.

[0136] Figure 6This is a graph showing the Hunter Whiteness Index (Hunter Lab) vs. the in vitro UVA Protection Factor (PF) rating of many samples measured using a Labsphere UV2000s spectrophotometer. The samples' bulk Whiteness Index (Hunter Lab) was analyzed using an Xrite spectrophotometer, and the in vitro UVA Protection Factor (PF) was analyzed using a Labsphere UV2000s. Samples #1-#14 and #19-#20 showed lower Whiteness Indexes (less whitening on the skin) than all the comparison samples. Samples #16-#18 had higher Whiteness Indexes (more severe whitening on the skin) and higher UVA PFs (more UVA protection) than all the comparison samples.

[0137] Figure 7 This graph shows the UVA PF rating measured using a Labsphere UV2000s spectrophotometer versus the in vitro UVB absorbance measured using a Hitachi spectrophotometer. The in vitro UVB absorbance (SPF) and UVA PF rating (UVA protection factor) of the mineral sunscreen samples were analyzed using both Hitachi and Labsphere UV2000s spectrophotometers. Higher UVA PF ratings and higher in vitro UVB absorbance provide greater broad-spectrum protection. Samples #1-#11 and #13-#20 exhibited higher broad-spectrum protection than control samples #2-#7.

[0138] Figure 8 This is a graph showing UVA PF rating vs. in vitro SPF measured using a Labsphere UV2000s spectrophotometer. The properties of UVA PF rating and in vitro SPF values ​​for mineral sunscreen samples were analyzed using a Labsphere UV2000s spectrophotometer. Higher SPF and higher in vitro UVA PF ratings provide higher broad-spectrum sun protection. All samples provided more broad-spectrum protection than control samples #2-#7.

[0139] Figure 9A -B presents various sunscreen compositions and their test results. Figure 9A The data in -B shows various sunscreen compositions with different ZnO raw materials, as well as supporting data on initial viscosity and in vitro UVB absorbance compared to other products on the market.
