Problems solved by technology

[0003] 1. The makeup effect is not long-lasting, and it is easy to take off makeup; it is often caused by facial oil or sweating that causes makeup or makeup to fall off (it is more obvious for people with oily skin);
[0004] 2. The oil control effect is not ideal. After the skin is oily, the air permeability is reduced, and the face is prone to sticky feeling;
[0005] 3. At present, the foundation products on the market that claim to have a long-lasting makeup effect mainly use oil-soluble film-forming agents to achieve water resistance, but they cannot solve the makeup removal caused by facial sebum secretion;
[0006] 4. In order to achieve better coverage, the current foundation products on the market add a higher amount of powder, which makes it easy to produce floating powder and unnatural makeup effect when applying

Embodiment 1～4

[0033] See Table 1 for the formula of the long-wearing liquid foundation described in Examples 1-4.

[0034] The preparation method of the makeup liquid foundation described in embodiments 1 to 4 comprises the following steps:

[0035]①Preparation of the oil phase: Wet the raw materials No. 2-4 with the raw material No. 7, and grind them twice with a three-roller machine, add the remaining raw materials No. 6-14, stir evenly, and homogenize at 3000rpm for 1min. Transfer to a stirrer and stir for defoaming for 5 minutes to obtain an oil phase;

[0036] ②Preparation of the water phase: the raw materials of No. 16, 17, 19 and 20 are dispersed with the raw material of No. 15 and added to water (No. 1), and the raw material of No. 18 is added and stirred until completely dissolved and uniform to obtain the aqueous phase;

[0037] ③Emulsification: add the water phase to the oil phase under stirring, stir at a stirring speed of 300-400rpm, homogenize at 3000rpm for 3 minutes, transf...

Embodiment 5

[0052] In order to verify the effect of the film former on the amount of toner migration, a migration resistance test was performed.

[0053] Test method: according to the formula of embodiment 1, change the kind and / or content of film-forming agent (trimethylsiloxysilicate and sodium carboxymethyl cellulose), and film-forming agent is respectively according to the proportioning in table 2 Add it to the formula, use a dropper to take 0.30g of the liquid foundation in Table 2 and drop it on the forearm, spread it evenly with a spoon (smooth surface, reduce sticky material), and let it stand for 5 minutes to dry naturally. Use paper towels to press the three areas with the same strength, and use an analytical balance to weigh the weight increment (that is, the amount of foundation migration) of the three paper towels. The experimental results are shown in Table 3.

[0054] The anti-migration tests of the liquid foundations described in Examples 1 to 4 are shown in Table 4.

Embodiment 6

[0064] In order to verify the effect of the surface treatment agent in the colorant on the toner, the hydrophobicity and oleophobicity tests were carried out,

[0065] (1) Experimental principle: When the droplet is freely in the space not affected by the force field, it is spherical due to the existence of interfacial tension. However, when a droplet comes into contact with a solid surface, its final shape depends on the relative strength of the cohesive forces inside the droplet and the adhesion between the droplet and the solid. When a droplet is placed on a solid surface, the droplet can spread out on the solid surface automatically, or exist as a droplet with a certain contact angle with the solid surface. The contact angle is an important measure of the relationship between the wettability of the reactive substance and the liquid. θ=90° can be used as the boundary between wetting and non-wetting. When θ90 ° non-wetting.

Abstract

A make-up-holding foundation liquid comprises a film-forming agent comprising trimethylsiloxy silicate and sodium carboxymethylcellulose, wherein that film-forming agent comprise trimethylsiloxy silicate and sodium carboxymethylcellulose. As that foundation liquid of the invention is added with the mixture of the oil phase and the water phase such as trimethylsiloxy silicate and sodium carboxymethyl cellulose, the invention become a two-phase film forming technology, the film formed by the foundation liquid can tightly lock the toner, and simultaneously has the dual effect of water resistanceand oil resistance, thereby improving the anti-migration property of the foundation liquid.

Description

technical field [0001] The invention belongs to the technical field of cosmetics, and in particular relates to a long-lasting makeup liquid foundation. Background technique [0002] There are following defects in the liquid foundation currently available in the market: [0003] 1. The makeup effect is not long-lasting, and it is easy to take off makeup; it is often caused by facial oil or sweating that causes makeup or makeup to fall off (it is more obvious for people with oily skin); [0004] 2. The oil control effect is not ideal. After the skin is oily, the air permeability is reduced, and the face is prone to sticky feeling; [0005] 3. At present, the foundation products on the market that claim to have a long-lasting makeup effect mainly use oil-soluble film-forming agents to achieve water resistance, but they cannot solve the makeup removal caused by facial sebum secretion; [0006] 4. In order to achieve better coverage, the current foundation products on the marke...
