Description

Matte eyeliner and preparation method thereof

Technical Field

The invention belongs to the field of cosmetics, and particularly relates to an eyeliner and a preparation method thereof.

Background

The eye line products are color cosmetic products which are commonly used for eyes to make eyes have spirit and increase contour sense, are deeply loved by lovers, and comprise four major categories of eye line paste, dipping type eye line pen, eye line gel pen and eye line liquid pen. Most of the eyeliner pens in the market are bright, and the matte eyeliner pens are increasingly in market demand due to the fact that the matte eyeliner pens are made by flowing in a dressing mode. Most of the film forming agents of the eyeliner pen are bright, and the matte effect is difficult to be displayed in the direct liquid eyeliner. The silica powder is generally utilized to achieve the matte feel of cosmetics, but because the discharge hole of the eyeliner is thinner, the pen point is easy to block, meanwhile, solid particles can be settled to enable water to be not smooth, the matte effect cannot be sustained, an eyeliner pen is generally manufactured in order to meet the requirements of users on the matte feel, the eyeliner pen is a solid eyeliner product containing wax base, and has certain hardness, so that the use feel is not very good.

Patent CN202011388816.8 discloses an eye liner gel pen based on hectorite lipophilic thickener and a preparation method thereof. The eye gel pen comprises, by weight, 0.2-1% of a lipophilic thickener of hectorite, 5-10% of polyethylene, 0-0.8% of mica, 1-5% of VP/hexadecene copolymer, 11.5-15% of an adhesive, 23.4-26% of a colorant, 0.5-2% of phenylpropyl dimethyl siloxysilicate, 1-3% of lauroyl lysine, 0.5-3% of polyhydroxystearic acid, 18-20% of a humectant, 25-35% of a film forming agent and 0.1% of an antioxidant. The composition of the oily thickener has excellent dispersion performance in oily environment, so that the micro-particles of the toner are uniformly distributed, and the color of the product is improved. But not easy to detach and make-up, the eye skin is sensitive and fine, the hardness of the eye line gel pen is stronger to the pulling sense of eyes, and the irritation of the eye line gel pen is not as small as that of an eye line gel pen in general.

Patent CN201810657569.3 discloses an eyeliner and a preparation method thereof. The composite material consists of the following components in parts by weight: 30-50 parts of acrylic copolymer, 10-20 parts of polyethylene glycol, 5-8 parts of propylene glycol, 3-8 parts of isopropyl palmitate, 1-3 parts of titanium dioxide, 3-10 parts of colorant and 50-120 parts of water. The invention adopts the acrylic ester copolymer, reduces the addition of the surfactant with skin irritation, and the prepared eyeliner has texture after being smeared, quite clear line feel, lasting makeup, difficult corona make-up, high brightness and good water resistance and oil resistance. Which belongs to bright eyeliner.

Patent CN202010825975.3 discloses a pearlescent eye-liner liquid and a preparation method thereof. The raw materials of the invention comprise the following components in parts by weight: 3-6 parts of wetting agent, 2-30 parts of solvent, 0.5-2 parts of dispersing agent, 20-45 parts of thickening suspending agent, 1-8 parts of pearling agent, 3-8 parts of colorant, 0.5-1 part of bactericide and 40-60 parts of film forming agent. The patent also uses a plurality of powder raw materials, so a plurality of thickening suspending agents are added to stabilize the system, but the influence on the viscosity is also great, so the material is thick, the viscosity is great, and the stable continuous liquid outlet is achieved by adding no or little thickening agent in the formula.

The invention relates to an aqueous matte eye liner liquid and a preparation method thereof, wherein the eye liner liquid is simple in raw materials, easy to obtain, safe and nontoxic, and the eye liner liquid film forming agent and powder are screened and blended by multiple particle sizes and proportions by selecting and using pre-dispersed aqueous color paste and a system to match perfectly, so that the makeup holding effect is improved closely when the eye liner liquid film forming agent and the powder are attached to skin. The matte effect of the formula is mainly provided by silica, the silica is matched with various particle sizes, the matte effect is good, the silica is easy to disperse, the silica is suspended in a material body under the combined action of a thickening agent and a film forming agent, and the silica is uniformly distributed on the film forming agent after being smeared, so that each painting has an extremely high matte effect.

The eyeliners of examples 1 to 13 were each applied to the skin surface of the back of the human hand with a 3mm wide and 100mm long film, a small amount of the clear water film was applied to the finger pad, the number of applications when the film began to fall off was recorded, the test was repeated 10 times for each group of samples, the maximum and minimum values of each group were discarded, and the remaining average value was taken. The test results are shown in Table 1.

As can be seen from Table 1, examples 1 to 4 show that the water-repellent effect of silica 3022 in combination with the acrylic copolymer and the styrene/acrylic copolymer was excellent at 20:10, the amount of silica slightly affected the water-repellent effect, examples 5 to 7 show that the water-repellent effect was affected by ordinary silica alone, the water-repellent effect was best without adding silica at all, and examples 8 to 13 show that the water-repellent effect of the styrene/acrylic copolymer was superior to that of the acrylic copolymer.

Comparative test 2: and (5) testing the matte effect.

Respectively taking the examples 1-13, uniformly coating the materials with consistent glossiness, testing by a glossiness meter, placing the meter on the materials to be tested, immediately displaying test data, pressing a power key, recording the current test data, and automatically calculating the maximum value, the minimum value, the average value and the mean square difference value. A smaller mean square value indicates a more uniform gloss of the surface of the measured material. The test results are shown in Table 2.
