Problems solved by technology

[0003] In the prior art, due to the oil-in-water and water-phase powder dispersion type liquid foundation, it has the advantage of moist skin feeling, and at the same time has the disadvantage of poor makeup setting effect
Water-in-oil and oil-dispersed liquid foundations have the advantages of long-lasting makeup, but also have the disadvantage of sticky skin feeling
At the same time, there is a risk of instability in the single-phase powder dispersion system. Once layered, it will not be able to apply makeup evenly. To prevent layering, more stabilizers (water phase powder dispersion) and powder (oil phase dispersant) need to be added to the formula. ), thus affecting the skin feel of the product
[0004] Therefore, a liquid foundation product has been developed to solve the technical defects that the liquid foundation products in the prior art have the technical defects that the long-lasting makeup and refreshing skin feeling cannot be satisfied at the same time and the stability is difficult to adjust, which has become an urgent problem to be solved by those skilled in the art.

Embodiment 1

[0031] Mix 15g of perfluorooctyltriethoxysilane with 95% alcohol at a ratio of 1:1 to prepare a composite surface treatment solution, ready to use.

[0032] Add 900g of titanium dioxide, 70g of iron oxide yellow, 22g of iron oxide red, and 8g of iron oxide black into the high-speed mixer. Under high-speed stirring, spray the pre-prepared composite surface treatment liquid into the high-speed mixer through the oil spray tank. Stir well to make the reaction solution and the inorganic powder mix evenly.

[0033] The powder is discharged, immediately sent to an oven, baked at 105°C for 4 hours, cooled naturally and discharged to obtain 1# foundation premix.

Embodiment 2

[0035] Mix 30g of perfluorooctyltriethoxysilane with 95% alcohol evenly at a ratio of 1:1 to prepare a composite surface treatment solution, ready to use.

[0036] Add 900g of titanium dioxide, 70g of iron oxide yellow, 22g of iron oxide red, and 8g of iron oxide black into the high-speed mixer. Under high-speed stirring, spray the pre-prepared composite surface treatment liquid into the high-speed mixer through the oil spray tank. Stir well to make the reaction solution and the inorganic powder mix evenly.

[0037] The powder is discharged, immediately sent to an oven, baked at 105°C for 4 hours, cooled and discharged naturally, and the 2# foundation premix is ​​obtained.

Embodiment 3

[0039] Mix 45g of perfluorooctyltriethoxysilane with 95% alcohol at a ratio of 1:1 to prepare a composite surface treatment solution, ready to use.

[0040] Add 900g of titanium dioxide, 70g of iron oxide yellow, 22g of iron oxide red, and 8g of iron oxide black into the high-speed mixer. Under high-speed stirring, spray the pre-prepared composite surface treatment liquid into the high-speed mixer through the oil spray tank. Stir well to make the reaction solution and the inorganic powder mix evenly.

[0041] The powder is discharged, immediately sent to an oven, baked at 105°C for 4 hours, cooled naturally and discharged to obtain 3# foundation premix.

Abstract

The invention discloses a liquid foundation with rapid layering and redispersion properties and a preparation method thereof. The liquid foundation with the rapid layering and redispersion properties comprises a premix which is added at a weight percentage of 10%-20%. The preparation method of the premix comprises performing uniform surface treatment on inorganic powder of titanium dioxide and ferric oxide through perfluorooctyl triethoxysilane surface treating agent, wherein the perfluorooctyl triethoxysilane surface treating agent is, by weight, 1%-12% of the total weight of the inorganic powder of titanium dioxide and ferric oxide. The liquid foundation with the rapid layering and redispersion properties is a water-in-oil agent and accordingly can provide light skin feeling, achieve high water-resistance and avoid makeup meltdown, and meanwhile, can eliminate the risk of instability and enhance product utilization interestingness.

Description

technical field [0001] The invention relates to the field of daily cosmetics, in particular to a water-in-oil liquid foundation with unique properties of rapid layering and redispersion, light and smooth application and a preparation method thereof. Background technique [0002] Liquid foundation is a very important cosmetic category. It acts as a protective screen between the skin and the outside world, preventing makeup and dust in the air from entering the skin. The appearance of ordinary liquid foundation is an emulsified system with uniform texture and a single-phase (oil or water) powder dispersion system. Oil-in-water and water-phase powder dispersion type liquid foundation, skin feels moist, low stickiness, easy to apply. Water-in-oil and oil-phase powder dispersion type liquid foundation, which has the advantages of water resistance and long-lasting makeup. [0003] In the prior art, due to the oil-in-water and water-phase powder dispersion type liquid foundations...
