Description

Technical Field

[0001] The invention belongs to the technical field of children's cosmetics, and in particular relates to a children's sunscreen mousse composition and a preparation method thereof. Background Art

[0002] Children's sunscreen products on the market are mainly divided into pure physical sunscreen, pure chemical sunscreen and physical and chemical combined sunscreen according to the type of sunscreen. Among them, pure physical sunscreen products occupy about 80% of the market share due to their higher safety. However, the "Technical Guidelines for Children's Cosmetics" clearly do not allow the use of raw materials prepared by new technologies such as genetic technology and nanotechnology, which means that traditional nano-level physical sunscreens cannot be used in children's products. Therefore, non-nano-level physical sunscreens need to be used, which not only affects the sunscreen effect of the product, but also leads to the need to increase the amount of physical sunscreens in order to achieve sufficient protection, resulting in poor use, whitening, dryness and other disadvantages.

[0003] Although physical and chemical sunscreen products combine the advantages of physical and chemical sunscreens, they still have some disadvantages similar to pure physical sunscreens, but to a lesser extent. Many commonly used chemical sunscreen ingredients in pure chemical sunscreen products, such as benzophenone-3 and ethylhexyl methoxycinnamate, are controversial due to their potential endocrine disruption risks or skin irritation; in addition, low molecular weight chemical sunscreens are more likely to penetrate the skin, resulting in insufficient mildness.

[0004] Children's sunscreen products on the market are mainly divided into sunscreen lotions / creams and sunscreen sprays according to product dosage forms. Sunscreen lotions / creams usually have good waterproof properties and durability, but they are often sticky and may cause discomfort to children after application. In addition, the application process of sunscreen lotions / creams is relatively long, especially when sunscreen measures need to be completed quickly before outdoor activities. This is particularly inconvenient. Sunscreen sprays are loved by some parents for their convenient use and can quickly cover a large area of ​​skin. However, spray products have a certain risk of inhalation, especially for children whose respiratory systems are not yet fully developed.

[0005] Therefore, there is an urgent need for a children's sunscreen mousse composition and a preparation method thereof to solve the deficiencies of the prior art problems. Summary of the invention

[0006] The first aspect of the present invention is to provide a children's sunscreen mousse composition, which has good mildness, sunscreen effect, stability, and can provide a dense mousse texture.

[0007] The second aspect of the present invention is to provide a method for preparing a children's sunscreen mousse composition, and the above-mentioned children's sunscreen mousse composition can be prepared by the preparation method.

[0008] To achieve the above objectives, the present invention provides a children's sunscreen mousse composition, comprising an agent and a propellant, wherein the agent comprises a phase A, a phase B, a phase C, a phase D, and a phase E, wherein, by weight, the phase A comprises 30 to 60 parts of a first solvent, 0.02 to 0.1 parts of a chelating agent, 0.25 to 0.35 parts of a thickener, 0.3 to 0.5 parts of p-hydroxyacetophenone, and 3.5 to 7 parts of a moisturizer, and the thickener comprises xanthan gum; the phase B comprises 12 to 22 parts of oil, 5 to 10 parts of a first sunscreen agent, 0.01 to 4 parts of a sunscreen synergist, 2 to 4 parts of an emulsifier, 0.04 to 0.23 parts of an antioxidant, and 0.8 to 2 parts of a film-forming agent, and the first sunscreen agent comprises ethylhexyl triazone, diethylhexyl butyramido triazone, bis-ethylhexyloxyphenol methoxyphenyl triazine, and drometrizole triazine. At least one of siloxane and polysilicone-15; the emulsifier includes potassium cetyl phosphate and polyglyceryl-10 laurate, the sunscreen enhancer includes at least one of crabapple seed oil, acrylic acid (ester) copolymer and butyl octanol salicylate; the C phase includes 0.01-20 parts of the second solvent and 0.01-3 parts of the second sunscreen, the second sunscreen includes at least one of terephthalylidene dicamphor sulfonic acid and methylene bis-benzotriazolyl tetramethylbutylphenol; the D phase includes 0.3-1.5 parts of preservatives, 0.01-0.3 parts of skin protectants, and 1-3 parts of fillers; the E phase includes 0.01-3 parts of pH adjusters and 0.01-5 parts of the third solvent; the propellant includes at least one of butane, isobutane, propane, isopentane, hydrofluorocarbon 152A, propane-butane, and carbon dioxide.

[0009] Furthermore, the thickener of the present invention also includes at least one of carbomer, ammonium acryloyldimethyltaurate / VP copolymer, gellan gum, polyacrylate cross-linked polymer-6, sodium polyacryloyldimethyltaurate, and acrylic acid (ester) / C10-30 alkyl acrylate cross-linked polymer. Xanthan gum is known for its excellent suspension ability and temperature stability. When xanthan gum is combined with other thickeners, the product can be better sprayed in a uniform and fine form.

[0010] Furthermore, the emulsifier of the present invention also includes at least one of sodium stearoyl glutamate, polysorbate-60, cetearyl alcohol and behenyl alcohol. Potassium cetyl phosphate is an anionic emulsifier that improves the stability of the emulsified system by increasing the charge density of the emulsified system; polyglyceryl-10 laurate is a non-ionic emulsifier that stabilizes the emulsion by increasing the interfacial film strength, so potassium cetyl phosphate and polyglyceryl-10 laurate can form a very stable emulsion when used together. Potassium cetyl phosphate and polyglyceryl-10 laurate are further combined with other emulsifiers to further effectively promote the uniformity and stability of the product, so that the product is sprayed in a more dense form.

[0011] Furthermore, the preservative of the present invention includes at least one of phenoxyethanol, 1,2-hexanediol, 1,2-pentanediol, and ethylhexylglycerol. When these preservatives are used alone or in combination, they can provide extensive protection for the product to prevent microbial contamination, thereby ensuring the safety and stability of the product. In addition, since they all have low irritation, they are very suitable for use in children's sunscreen mousse compositions.

[0012] Further, the oil of the present invention includes at least one of C12-15 alcohol benzoate, dibutyl adipate, isononyl isononanoate, isopropyl lauroyl sarcosinate, propyl heptyl octanoate, coconut oil alcohol-caprylate / caprate, octyl polymethicone, propylene glycol dicaprylate / dicaprate, polydimethicone, squalane, sunflower seed oil, grape seed oil, sea buckthorn fruit oil, avocado tree fruit butter, camellia seed oil, diisopropyl sebacate and dicaprylyl carbonate. The oil helps to dissolve and disperse the first sunscreen and the second sunscreen, thereby improving the overall sunscreen efficacy; at the same time, the oil also has good waterproof performance, so that the children's sunscreen mousse composition can still maintain effective protection when swimming or sweating.

[0013] Furthermore, the film former of the present invention includes at least one of VP / hexadecene copolymer, VP / acrylates / lauryl methacrylate copolymer, trimethylsiloxysilicate, and polyester-7. Film formers play a key role in children's sunscreen mousse compositions. They can form a protective film that can not only help fix the first sunscreen and the second sunscreen, but also provide additional protection.

[0014] Furthermore, the skin protectant of the present invention includes at least one of Centella asiatica extract, dipotassium glycyrrhizinate, ectoine, β-glucan, inulin, gentian root extract and allantoin. These ingredients have soothing, anti-inflammatory, moisturizing and repairing effects, so adding the skin protectant to the children's sunscreen mousse composition can provide comprehensive care and protection for children's skin while providing efficient sunscreen, ensuring that children can also enjoy a safe and comfortable skin care experience during outdoor activities.

[0015] Furthermore, the filler of the present invention includes at least one of silica, polymethylsilsesquioxane, calcium starch octenyl succinate and aluminum starch octenyl succinate. The filler can absorb excess grease and reduce oiliness, and is particularly suitable for children to use during outdoor activities; at the same time, the filler can improve the stability of the children's sunscreen mousse composition; in addition, some fillers (such as polymethylsilsesquioxane) can also enhance the waterproof performance of the children's sunscreen mousse composition and improve the durability of the sunscreen effect.

[0016] Furthermore, the pH regulator of the present invention comprises at least one of arginine, sodium hydroxide, potassium hydroxide, tromethamine, aminomethyl propanol and triethanolamine.

[0017] Furthermore, the chelating agent of the present invention includes disodium ethylenediaminetetraacetate (EDTA-2Na).

[0018] Furthermore, the antioxidant of the present invention comprises at least one of tocopherol acetate, pentaerythritol tetrakis (di-tert-butyl hydroxyhydrocinnamate) ester and butylated hydroxytoluene.

[0019] Furthermore, the moisturizing agent of the present invention includes at least one of hyaluronic acid, sodium hyaluronate, panthenol, butylene glycol, and polyethylene glycol-8.

[0020] Furthermore, the first solvent, the second solvent and the third solvent of the present invention are all water.

[0021] Further, the mass ratio of the agent to the propellant of the present invention is 70 to 98:2 to 30. Specifically, the mass ratio of the agent to the propellant may be, but is not limited to, 70:30, 75:25, 80:20, 85:15, 90:5, 98:2.

[0022] Accordingly, the second aspect of the present invention provides a method for preparing a children's sunscreen mousse composition, comprising the steps of:

[0023] (1) Place phase A into an emulsifying pot, stir and heat to 80-85°C until it is evenly dissolved;

[0024] (2) Add phase B into the oil phase pot, stir and heat to 80-85°C until it is evenly dissolved;

[0025] (3) maintaining the temperature at 80-85° C., adding the mixture obtained after step (2) to the mixture obtained after step (1), and stirring evenly;

[0026] (4) cooling the mixture obtained in step (3) and adding phase C during the cooling process, and stirring evenly;

[0027] (5) After step (4), continue cooling to below 45° C., then add phase D and phase E, and stir evenly;

[0028] (6) The material obtained in step (5) is sequentially filled, pressed into a propellant, sealed, and packaged.

[0029] Furthermore, the present invention presses the propellant into the dosage form, and the emulsifier and thickener in the dosage form a thin film under the action of the propellant. These thin films wrap the gas released by the propellant to form a stable foam structure. The foam structure allows the product to be sprayed in the form of fine foam rather than atomized small droplets, which means that there is no atomization during spraying, thereby greatly reducing the risk of inhalation for children; at the same time, the intervention of the propellant is also helpful for the refreshing feeling of the skin.

[0030] Furthermore, step (1) of the present invention comprises adding a first solvent, a chelating agent, a thickener, p-hydroxyacetophenone, and a moisturizer into an emulsifying pot; and step (2) comprises adding oil, a first sunscreen agent, a sunscreen enhancer, an emulsifier, an antioxidant, and a film-forming agent into an oil phase pot.

[0031] Furthermore, step (4) of the present invention comprises premixing the second solvent and the second sunscreen agent to obtain a phase C material, and then adding the dissolved phase C material during the cooling process;

[0032] Furthermore, step (5) of the present invention comprises pre-mixing the pH regulator and the third solvent to obtain the phase E, and then adding the preservative, the skin protectant, the filler and the dissolved phase E after cooling to below 45°C.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] 1. Children's skin defense ability is relatively poor, and the safety of cosmetics is particularly important. Therefore, the first sunscreen and the second sunscreen of the present invention are both macromolecular sunscreens, which are not easy to penetrate the stratum corneum into the deep layer of the skin, thereby reducing the potential risk of irritation to children's skin. At the same time, the oil-soluble first sunscreen and the water-soluble second sunscreen can provide comprehensive UVA and UVB protection, that is, the required SPF value and PA grade are achieved at a lower concentration, thereby reducing the amount of single sunscreen, and further reducing the potential risk of irritation to children's sensitive skin. Film-forming agents are also introduced to make the first sunscreen and the second sunscreen evenly distributed on the skin surface and form a lasting protective layer, which not only further improves the sunscreen effect, but also reduces the amount of sunscreen used; sunscreen synergists are also introduced to help stabilize the sunscreen to prevent it from decomposing under light, prolong the residence time of the first sunscreen and the second sunscreen on the skin, thereby further reducing the amount of sunscreen used. Therefore, the present application adopts the first sunscreen, the second sunscreen, the film-forming agent and the sunscreen enhancer as raw materials, which ensures the sunscreen effect while reducing the amount of sunscreen, thereby reducing the potential risk of irritation to children's sensitive skin and improving the safety and mildness of the product.

[0035] 2. The present application carefully selects potassium cetyl phosphate and polyglyceryl-10 laurate as emulsifiers and uses xanthan gum as a thickener, so that the children's sunscreen mousse composition can remain physically stable for a long time; at the same time, potassium cetyl phosphate, polyglyceryl-10 laurate and xanthan gum have good compatibility with the propellant, which ensures that the product remains stable under high pressure and can form a fine and uniform foam when sprayed, providing a dense mousse texture.

[0036] 3. The children's sunscreen mousse composition of the present invention adopts a unique foam formulation packaging design, which is sprayed on the skin in the form of mousse, without any particles presented separately, which is convenient to apply, and there is no risk of inhalation from the spraying to the use process, which further improves the safety of the product. In addition, the foam formulation packaging has good sealing, which reduces the demand for preservatives, so that more gentle and low-irritation preservative ingredients can be selected, thereby reducing the potential stimulation to children's skin; the foam formulation packaging also has good shielding, which makes it unnecessary for the ingredients in the product to be completely evenly mixed, and the efficacy can be restored by simply shaking before use, which not only reduces the amount of emulsifiers and thickeners used, reduces the possible stimulation to the skin, but also makes the texture of the product lighter and more delicate, easy to apply, and even a small amount of use can achieve an effective sunscreen effect. In addition, the product can be quickly released with just a light press, and the operation is extremely simple; and the foam formulation packaging is easy to carry and store, which greatly enhances convenience. Therefore, compared with traditional formulations (such as sunscreen milk / cream), the children's sunscreen mousse composition of the present invention shows better sealing, shielding, safety, ease of use and portability.

[0113] Test method: Refer to the specific requirements of ISO 24442:2022 (E) Cosmet ics-Sun protection test methods-In vivo determination of sunscreen UVA protection for testing. The subject takes a prone position and his back is irradiated. The minimum melanization amount (MPPD value) of the subject's skin to ultraviolet radiation is predicted 24 hours before the test, and the ultraviolet radiation amount is adjusted according to the predicted results for testing the object to be tested. The test first selects a normal skin area of ​​not less than 30cm2 on the back of the subject, and evenly applies the object to be tested or the reference substance in the above-mentioned area at a dosage of (2.00+0.05)mg / cm2; then select the UVA exposure amount according to the specification requirements, and irradiate in three situations: ① The subject's skin is not coated with the object to be tested; ② Apply the reference substance; ③ Apply the object to be tested. Observe the experimental results after 2 to 4 hours, and record the MPPD values ​​in the three cases respectively;

[0114] PFA value calculation method: The PFA value of a single subject protected by the test substance or reference substance is expressed by the following formula: PFAi = MPPD value of protected skin / MPPD value of unprotected skin.

[0130] By comparing Example 1 with Comparative Examples 1-2, it can be seen that the introduction of film formers and sunscreen enhancers can significantly improve the sunscreen effect. This is because the film former can form a protective film on the skin surface, which helps to reduce the chance of ultraviolet rays directly contacting the skin; while the sunscreen enhancer improves the overall sunscreen performance by stabilizing the sunscreen.

[0131] By comparing Example 1 with Comparative Example 3, it can be seen that the introduction of skin protectants can further improve the sunscreen effect. This is because skin protectants have soothing, anti-inflammatory, moisturizing and repairing effects, which can help resist free radical damage, reduce inflammatory reactions, etc., thereby indirectly enhancing the effectiveness of sunscreen products.

[0132] By comparing Example 1 with Comparative Examples 4 to 6, it can be seen that removing any one of potassium cetyl phosphate, polyglyceryl-10 laurate and xanthan gum will affect the mousse state, and removing potassium cetyl phosphate will also affect the stability, which shows that selecting potassium cetyl phosphate and polyglyceryl-10 laurate as emulsifiers and selecting xanthan gum as thickener can enable the children's sunscreen mousse composition to maintain physical stability for a long time; at the same time, potassium cetyl phosphate, polyglyceryl-10 laurate and xanthan gum also have good compatibility with the propellant, which ensures that the product remains stable under high pressure and can form delicate and uniform foam when sprayed, providing a dense mousse texture.

[0133] By comparing Example 1 with Comparative Example 7, it can be seen that the compatibility between dimethyl ether propellant and potassium cetyl phosphate, polyglycerol-10 laurate and xanthan gum is poor, and thus a dense mousse texture cannot be provided; in addition, dimethyl ether propellant may also cause slight irritation to the skin.

[0134] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
