Abstract
The invention relates to the field of cosmetics and discloses a sunscreen radiation-proof foundation liquid with high lasting cosmetic power and a preparation method thereof. The liquid foundation comprises the following components in percentage by mass: 0.5-3.5% of thickening agent, 1-3% of film forming agent, 2-6% of emulsifying agent, 3.5-6.5% of coloring agent with gamma-polyglutamic acid grafted on surface, 1-20% of humectant, 1-3% of suspending agent and the balance of water. The surface of the colorant is grafted with the gamma-polyglutamic acid, so that the colorant has high adhesiveness on the surface of skin, and the foundation liquid has good concealing effect and make-up holding power.

Broadly speaking, make-up base products include foundation lotions, foundations, concealers, body creams, BB/CC creams, air cushions, facial make-up creams, and the like. The foundation make-up can play a role in backing up and covering blemishes on the skin, covering facial blemishes, homogenizing the skin, giving the skin smooth and greasy feeling and the like, and is the most basic product in the foundation make-up products.

Compared with the comparative example 2, the foundation liquid concealing effect, the cosmetic power and the sun-screening effect of the embodiment 1 are obviously higher than those of the comparative example 2 by modifying the colorant by adopting the method of the invention.
Compared with example 1, in example 4, in the process of preparing the coloring agent with the surface grafted with the gamma-polyglutamic acid, baicalin is not added, and the makeup-holding capacity and the sun-screening effect of the base powder are obviously lower than those of example 1, because the baicalin has the effects of absorbing ultraviolet rays and removing free radicals, the photocatalytic activity of titanium white serving as a coloring agent can be reduced while sunlight is resisted, and the gamma-polyglutamic acid is prevented from being degraded under the actions of the titanium white and the ultraviolet rays after makeup to cause the shedding of the coloring agent.
Compared with example 1, comparative example 1 has no ball milling on the colorant in the process of preparing the colorant with the surface grafted with the gamma-polyglutamic acid, and the foundation solution concealing effect, make-up holding power and sun-proof effect of the colorant are obviously lower than those of example 1, because the hydroxyl on the surface of the colorant is activated from the original dormant state after the colorant is acted by the mechanical force of the ball mill, and the colorant has higher reaction activity, thereby being beneficial to the subsequent reaction and grafting more gamma-polyglutamic acid and baicalin on the colorant.
Compared with example 1, in comparative example 3, baicalin and the coloring agent with the gamma-polyglutamic acid grafted on the surface are added in a dispersing way, but are not grafted on the coloring agent, the foundation solution concealing effect and the make-up holding power are obviously lower than those of example 1, because when the baicalin and the coloring agent are added in a dispersing way, the baicalin is difficult to play a role in reducing the photocatalytic activity of the coloring agent titanium white, and the gamma-polyglutamic acid is easy to degrade under the action of the titanium white and ultraviolet light after the make-up, so that the coloring agent is peeled off.
Although the present invention has been described in detail with reference to the embodiments, it will be understood by those skilled in the art that the embodiments may be modified or changed without departing from the spirit of the present invention within the scope of the appended claims.

(C) adding quaternary ammonium salt-52 into the prepolymer modified colorant dispersion liquid, uniformly mixing, continuing to react for 1.5-2.5 h at 75-85 ℃, and sequentially centrifuging, washing and drying to obtain a cation modified colorant;
(D) adding gamma-polyglutamic acid into water, fully dissolving, then adding a cation modified coloring agent, uniformly dispersing by ultrasonic, stirring for 0.5-2.5 h, and sequentially centrifuging, washing and drying to obtain the coloring agent with the gamma-polyglutamic acid grafted on the surface.
4. The foundation of claim 3 wherein in step (C), baicalin is added to the prepolymer modified colorant dispersion along with quaternary ammonium salt-52 as quaternary ammonium salt-52 is added.
5. The foundation solution of claim 3, wherein in the step (B), the mass-to-volume ratio of the pretreatment coloring agent to the dimethyldimethoxysilane to the ethanol aqueous solution is 1g:3 to 5g:5 to 10 mL.
6. The foundation solution of claim 5, wherein in step (C), the mass ratio of the quaternary ammonium salt-52 to the pretreatment colorant in step (B) is 0.6 to 0.9: 1.
7. The foundation solution of claim 5, wherein in step (C), the mass ratio of baicalin to the pretreatment colorant in step (B) is 0.3-0.5: 1.
8. The foundation solution of claim 3, wherein in step (D), the mass-to-volume ratio of the gamma-polyglutamic acid, the cation modified colorant and the water is 0.7-1.2 g:1g: 15-20 mL.
9. The foundation of claim 1 wherein said thickener comprises at least one of cyclopentadimethylsiloxane, a methyl methacrylate crosspolymer, octyl methicone; the film forming agent comprises at least one of hydrogenated polyisobutene, methyl polytrimethylsiloxane, cyclohexasiloxane and polydimethylsiloxane; the emulsifier comprises at least one of PEG-10 polydimethylsiloxane and cetyl dimethicone copolyol; the humectant comprises at least one of butanediol, sodium hyaluronate, betaine and palmitoyl proline; the suspending agent comprises disteardimonium hectorite.
10. A method of preparing the liquid foundation of any one of claims 1 to 9, comprising the steps of:
(1) adding humectant into partial water, and dissolving to obtain phase A;
(2) mixing the thickening agent, the film forming agent, the emulsifying agent and the suspending agent, adding the rest water, and uniformly mixing to obtain a phase B;
(3) and adding the colorant with the surface grafted with the gamma-polyglutamic acid into the phase B, fully mixing, adding the phase A, and uniformly mixing to obtain the sunscreen radiation-proof foundation liquid with high lasting cosmetic power.
