Description

Technical Field

[0001] This invention relates to the field of daily chemical technology, and in particular to a gentle facial cleansing mousse composition for effectively removing sunscreen, its preparation method, and its application. Background Technology

[0002] Many ingredients in sunscreens (especially chemical sunscreens) are oil-soluble, requiring the use of oils or solvents to dissolve them during makeup removal. Oil-based products need to be thoroughly emulsified with water to avoid oil residue causing clogged pores or other skin problems.

[0003] Mousse sunscreen remover is a lightweight, foamy makeup remover specifically designed to cleanse sunscreen. It combines makeup removal and cleansing functions, making it particularly suitable for daily use of lightweight or non-waterproof sunscreens. However, it is less effective with long-lasting, waterproof, or layered sunscreens and may require additional makeup remover.

[0004] Surfactants used in mousse-type makeup removers need to be gentle, produce rich foam, and have a certain degree of oil-dissolving ability. Waterproof sunscreens are a type of sun protection product designed for prolonged outdoor activities (such as swimming and sports), which can form a protective film with strong adhesion on the skin surface to resist the washing away of water and sweat.

[0005] Therefore, the present invention provides a gentle cleansing mousse composition for effectively removing sunscreen, its preparation method, and its application. Summary of the Invention

[0006] To solve the above-mentioned technical problems, the present invention provides a gentle cleansing mousse composition for effectively removing sunscreen, the composition comprising: sodium cocoaminopropionate, disodium cocoyl glutamate, bis(PPG-2 myristole polyether-10) adipate, and sodium lauroyl amphoteric acid; and the mass ratio of sodium cocoaminopropionate, disodium cocoyl glutamate, bis(PPG-2 myristole polyether-10) adipate, and sodium lauroyl amphoteric acid is (8-20):(2-15):(0.1-3):(2-10).

[0155] This invention provides a gentle, mousse-textured facial cleanser for removing sunscreen. In the overall formulation, sodium cocoaminopropionate and disodium cocoyl glutamate are selected as the main surfactants, which can effectively remove oil and dirt from the skin surface while having very low skin irritation, making them suitable for sensitive and dry skin. Disodium cocoyl glutamate can cooperate with various surfactants (such as amphoteric or nonionic surfactants) to improve the overall gentleness of the formula. However, both have relatively weak makeup removal ability against waterproof sunscreens; therefore, this invention adds di(PPG-2 myristyl alcohol polyether-10) adipate.

[0156] Di(PPG-2-Myristole-10) adipate can dissolve some waterproof sunscreens, thus increasing the overall cleansing power of the product. However, its ester properties make it difficult to completely emulsify or remove when rinsed with water, potentially leaving a slight oily film on the skin. While this helps with moisturizing, it may not be enough for oily skin or consumers seeking a refreshing feel. Furthermore, the lipophilic nature of di(PPG-2-Myristole-10) adipate requires the use of appropriate emulsifiers; otherwise, it may struggle to form a stable emulsion in oil-water makeup removers. Additionally, its oily properties may conflict with amino acid surfactants, inhibiting foam formation or stability.

[0157] Therefore, in designing the formulation, this invention incorporates sodium lauroamphoacetate as both a thickener and an emulsifier, which can mitigate the drawbacks of the aforementioned di(PPG-2 myristyl oleate-10) adipate. This is because sodium lauroamphoacetate forms complex micelles with anions (such as sodium cocoyl aminopropionate), increasing viscosity and optimizing foam performance; effectively controlling the fineness and stability of the foam. However, the product obtained from the above formulation may exhibit turbidity or layering at low temperatures (<10℃). Additionally, the formulation of this invention also includes decyl glucoside, which has strong cleaning power, foam volume, and stability; however, in practice, its foam is found to be insufficiently fine and soft, and not suitable for sensitive skin.

[0158] The addition of sodium methyl taurate and sodium lauroamphoacetate provides a rich, dense, and stable foam that perfectly complements the mousse form.

[0159] The formulations obtained above vary in their optimal pH range. For example, sodium cocoaminopropionate and disodium cocoyl glutamate are more stable under neutral to slightly acidic conditions, while sodium methyl taurate and sodium sarcosinate may perform better at slightly acidic conditions (pH 5-6). Therefore, this invention designs the proportions of several formulations to maintain a balance in pH, foam stability, cleaning power, and component compatibility, resulting in a product with excellent performance.

[0161] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
