Description

Technical Field

[0001] This invention relates to the field of base makeup product technology, specifically to a base makeup product with a biphasic film-forming system and its preparation method. Background Technology

[0002] Currently, facial makeup products are mainly divided into skincare and color makeup categories. In the color makeup market, base makeup dominates. Most dual-phase film-forming base makeup products on the market typically have different focuses. For example, those emphasizing lightweight properties often lack sufficient coverage and stability; those emphasizing moisturizing effects need further improvement in staying power; and those emphasizing coverage suffer from a heavy feel and limited applicability due to excessively high powder content. This places higher demands on the development of dual-phase film-forming base makeup products. Chinese patent application (publication number CN118902884A) discloses a gentle, long-lasting foundation and its preparation method. By using titanium dioxide surface-treated with specific reagents combined with specific ingredients, it improves product stability and staying power; however, the product's water resistance needs further improvement. Summary of the Invention

[0003] To address the aforementioned issues, this invention provides a dual-phase film-forming base makeup product and its preparation method. By optimizing the selection and combination of raw materials in the system, the provided dual-phase film-forming base makeup product exhibits excellent water resistance, skin adhesion, and long-lasting properties, with a finer powder texture that adheres better to the skin, thus better meeting consumer needs.

[0004] This invention provides a base makeup product with a biphasic film-forming system, wherein the raw materials for its preparation, by mass percentage, include at least: Phase A: 0.1-5% organosilicon surfactant, 2-35% colorant, 0.02-20% silane film-forming agent, 0.01-55% conditioning agent, and 0.02-5% organosilicon modified clay; Phase B: 0.001-1% plant-derived film-forming agent, 1-20% polyol moisturizer, 0.1-2% inorganic salt, 0.1-2% preservative, and deionized water to make up the balance; wherein the silane film-forming agent includes at least trimethylsiloxysilicate and polymethylsilsesquioxane; and the plant-derived film-forming agent includes at least agave leaf extract.

[0005] The dual-phase film-forming system of the foundation product provided by this invention uses silane-based film-forming agents in combination with plant-derived film-forming agents, especially by simultaneously introducing trimethylsiloxysilicate, polymethylsilsesquioxane, and agave leaf extract. This allows the foundation to form a breathable, flexible, and highly adhesive hydrophobic film, providing excellent waterproof, sweatproof, and friction-resistant properties while reducing the stickiness caused by other ingredients, ensuring a non-greasy application feel and a dry touch.

[0006] In one embodiment, the raw materials for preparing the base makeup product of the biphase film-forming system, by mass percentage, include at least: Phase A: 3-4% organosilicon surfactant, 8-20% colorant, 3-10% silane film-forming agent, 10-30% conditioning agent, and 0.1-1% organosilicon modified clay; Phase B: 0.1-0.8% plant-derived film-forming agent, 10-15% polyol moisturizer, 0.5-1.5% inorganic salt, 1-1.5% preservative, and deionized water to make up the balance.

[0018] In one embodiment, the polyol moisturizer is selected from at least one of glycerin, propylene glycol, butylene glycol, or pentanediol.

[0019] In one embodiment, the inorganic salt includes at least magnesium sulfate.

[0020] In one embodiment, the preservative is selected from at least one of p-hydroxyacetophenone, 1,2-hexanediol, phenoxyethanol, or ethylhexylglycerin.
