Waterproof liquid eye shadow and preparation method thereof

Technical Field

The invention relates to the technical field of cosmetics, in particular to a waterproof liquid eye shadow and a preparation method thereof.

Background

When weather such as epidemic prevention and control, air drying are cold or haze appears, people often can wear the gauze mask, and the gauze mask that corresponds makes up uses double eyes and eyebrow portion as leading, and eyebrow point eye can be new-to-the-ear.

The eye shadow is a common eye cosmetic, and can make the eye position have the stereoscopic effect. However, the eye shadow is mainly divided into a powdery eye shadow and a liquid eye shadow, and the existing powdery eye shadow is easy to have the problems of easy falling, easy breakage, powder flying, insufficient fineness of the powder, large volume, insufficient durability and the like; however, when the aqueous liquid eye shadow meets rain and sweat, the problems of makeup, long-term standing and layering and the like are easily caused.

Disclosure of Invention

Based on the defects of the prior art, the invention aims to provide a waterproof liquid eye shadow which can achieve the effects of lasting water resistance, sweat resistance, full color development, portability, falling resistance, no powder flying and no layering.

In order to achieve the purpose, the invention adopts the technical scheme that:

In the waterproof liquid eye shadow provided by the invention, under the synergistic cooperation of the components in a specific proportion, the eye shadow exists in a liquid form, the powder flying and layering conditions cannot occur, the viscosity is moderate, the texture is light and thin, the eye shadow has a transparent feeling, and the lasting waterproof and sweat-proof effects can be achieved; under the condition of adding a sufficient amount of pearling agent, the product is full in color development, has fine and smooth pearly luster and is very suitable for refreshing and transparent makeup; in addition, the waterproof liquid eye shadow prepared by the invention has high skin applicability, no irritation and adverse side effect, falling resistance and convenient carrying.

Preferably, the film-forming agent is trimethylsiloxysilicate. When the trimethylsiloxy silicate is used as an oily film forming agent of the product, the color fixation is facilitated, the water-proof durability of the product can be prolonged, the caking is prevented, and the free flowing characteristic of the product is maintained.

Preferably, the thickener is a hydrogenated (styrene/isoprene) copolymer. By utilizing the excellent film forming and bonding capabilities of the hydrogenated (styrene/isoprene) copolymer, the viscosity of the liquid eye shadow prepared by the method is more moderate, and the components in the liquid eye shadow are mixed more uniformly.

Preferably, the adsorbent is silica dimethyl silylate. By selecting hydrophobic dimethyl silyl silica as an adsorbent and utilizing the porous structure and the larger internal adsorption surface area of the adsorbent, the prepared liquid eye shadow product has good thixotropy and stability.

Preferably, the emollient comprises 5-20 wt% of tridecyl alcohol trimellitate, 5-20 wt% of octyl dodecanol and 1-5 wt% of isopropyl isostearate; the humectant comprises 0.1-1 wt% of caprylyl glycol and 0.1-1 wt% of caprylic glyceride, wherein the caprylyl glycol accounts for the raw material components of the waterproof liquid eye shadow. The emollient and the humectant can effectively lubricate eye skin and keep sufficient moisture through mutual matching of specific proportions.

In the skin conditioner, the phytosterol isostearate is rich in phytosterol ester, and the phytosterol ester and cholesterol have similar structures and can be mutually substituted, so that the homology of the phytosterol ester and the skin is very good, the compatibility and the skin sticking performance of the phytosterol ester and the skin are good, and the skin conditioner has the skin feeling without being comparable to moisturizing and non-sticky. The phytosterol isostearate has high permeability to skin, can maintain skin surface moisture, promote skin metabolism, inhibit skin inflammation, and prevent sunburn, erythema and skin aging; has the characteristics of good use skin feeling (good spreadability, smoothness and no stickiness), good durability, difficult deterioration and the like. The bisabolol can protect and cure the skin, prevent the skin from being affected by daily tension, and accelerate the healing process of the skin. In addition, the anti-inflammatory property of the eye shadow mask also enables the prepared waterproof liquid eye shadow product to have multiple effects.
