Description

Paint light mirror color-holding lip glaze and preparation method thereof

Technical Field

The invention belongs to the field of cosmetics, and particularly relates to a paint-luster mirror surface color-holding lip glaze and a preparation method thereof.

Background

Lip color cosmetics are one of the fastest-accelerating products of beauty treatment and personal care in recent years, and the lip color cosmetics continue to grow at a high speed with the enhancement of beauty awareness of consumers and the gradual maturity of the beauty cosmetics market. With respect to lip color cosmetics, consumers prefer high gloss, moist, refreshing, long lasting moisturizing lip products. However, the existing long-acting durable products in the market are mostly matte and non-sticky products, and the products have the defects of poor moisture and moisture retention degree and easy drying; the moistening type product has the condition of poor freshness and persistence. The product which can achieve the combination of the two is few and few in the market.

CN104606093A discloses a water-in-oil emulsified lipstick, which contains the following components: water, octyldodecanol, pentaerythritol tetraisostearate, cyclopentadimethylsiloxane, ethylcellulose, ethanol, glycerol, polyglycerol-2-triisostearate, ethylene/propylene/styrene copolymer, butylene/ethylene/styrene copolymer, isododecane, polyglycerol-6 polyricinoleate, trimethylolpropane triisostearate, a colorant, disteardimonium hectorite, hydrogenated polyisobutene, polyglycerol-2 isostearate, rugosa, sodium chloride, phenoxyethanol and ethylhexylglycerol. The invention has higher gloss, saturated color and good makeup state for a long time, but the emulsified lipstick still has larger greasy feeling compared with oil-in-water and has less refreshing degree than the oil-in-water.

CN110302094A discloses a high-gloss non-stick lip glaze and a preparation method thereof, wherein the high-gloss non-stick lip glaze comprises the following components in percentage by weight: 0.1-10% of ethyl cellulose A, 0.1-10% of ethyl cellulose B and 0.1-30% of polydimethylsiloxane and polydimethylsiloxane/vinyl polydimethylsiloxane cross-linked polymer mixture, although a film with high glossiness and good waterproof effect can be formed on lips, the product has the defects of poor water-moistening and moisture-retaining degrees and easiness in drawing dry.

CN109330905A discloses a velvet matte lip glaze and a preparation method thereof, wherein the lip glaze comprises the following components in parts by weight: 27-40.5 parts of thickening agent, 0.1-1 part of humectant, 8.7-13.4 parts of colorant, 21-50 parts of softening agent, 0.1-0.3 part of antioxidant and 8-25 parts of skin feel regulator.

Therefore, there is a need to develop a product with good water retention, long-lasting moisture retention, long make-up time and high glossiness to meet the current consumer demands.

The lip moisture content (%) and the lip color change (the difference Δ L between the skin color tone after the lip glaze is used and before the lip mask is used, the larger Δ L indicates the more color tone of the lip with residual color, the better the gloss and the durability), were measured by a skin moisture meter, and the specific test results are shown in table 2:

TABLE 2

Test sample	Lip moisture content (%)	Lip color change (DeltaL)
			Example 1	60.2	2.2
Example 2	56.9	2.1
			Example 3	58.3	2.1
Example 4	57.2	2.2
			Example 5	56.8	2.2
Example 6	55.6	2.1
			Example 7	55.2	2.1
Comparative example 1	48.0	1.5
			Comparative example 2	49.1	1.6
Comparative example 3	54.7	2.0
			Comparative example 4	48.2	1.6
Comparative example 5	54.3	2.0
			Comparative example 6	54.7	2.0
Comparative example 7	50.8	2.0

From the above test data, it can be known that the lip moisture content of the gloss mirror surface color-retaining lip glaze prepared in the embodiments 1 to 7 is above 55% after being coated for 2 hours, and the lip color change (Δ L) value is above 2.1, which fully indicates that the gloss mirror surface color-retaining lip glaze of the present invention is an oil-in-water lip product, oil is an internal phase, and water is a continuous external phase, thereby well solving the greasy feeling of the oil paste product. Meanwhile, the oil phase film forming agent and the grease are matched with each other, and the glossiness, the persistence and the moistening degree of the lip glaze are greatly improved under the synergistic effect.

Lip glaze human body experiment

Selecting 1 healthy volunteer without serious system diseases, immunodeficiency or autoimmune diseases, allergy to cosmetics, acute inflammation on the face, hormone drugs or immunosuppressants, other clinical tests and external preparations, coating the gloss mirror color-retaining lip glaze prepared in the examples 1 to 7 and the lip glaze prepared in the comparative examples 1 to 7 on the skin of the lips of the volunteer, and taking pictures of the lips of the volunteer at four time points of the beginning, 2h, 4h and 6h respectively, wherein the pictures of the lips of the volunteer are respectively pictures of the lips of the volunteer coated with the gloss mirror color-retaining lip glaze prepared in the example 1 at the four time points in fig. 1A to 1C; FIGS. 2A-2C are photographs of the lips of volunteers who applied the paint-finish mirror-hold lip glaze prepared in example 2 at the four time points described above, respectively; FIGS. 3A-3C are photographs of the lips of volunteers who applied the paint-finish mirror-hold lip glaze prepared in example 3 at the four time points described above, respectively; FIGS. 4A to 4C are photographs of the lips of volunteers who applied the lip glaze prepared in comparative example 1 at the above four time points, respectively; FIGS. 5A to 5C are photographs of the lips of volunteers applied with the lip glaze prepared in comparative example 2 at the above four time points, respectively; FIGS. 6A to 6C are photographs of the lips of the volunteer who applied the lip glaze prepared in comparative example 3 at the above four time points, respectively; fig. 7A to 7C are photographs of the lips of the volunteer who applied the lip glaze prepared in comparative example 4 at the above four time points, respectively.

As is apparent from the above photographs, the lip gloss, color saturation, water wettability and persistence of the volunteer coated with the paint-luster mirror surface color-retaining lip glaze are obviously improved. This is sufficient to show that the lip glaze of the present invention has the glossiness and high color saturation of the all-oil type and water-in-oil type lip glazes, and at the same time, has higher water-wettability than the water-in-oil type lip glazes and the all-oil type lip glazes.

Poll testing

Female volunteers 20-40 years old, 70 people in total, were selected by the opinion score method. The gloss mirror color-holding lip glaze prepared in the above examples 1 to 7 and the lip glaze prepared in the comparative examples 1 to 7 were applied to lips of volunteers, and evaluation items of the above gloss, color saturation and cleaness were evaluated in sensory evaluation on 5 grades, wherein 5 grades were excellent; 4 is excellent; dividing into general according to the 3 point; 2 is divided into a difference; 1 is very poor; and the volunteers are asked to score at four time points of 0h (initial just smearing), 2h, 4h and 6h respectively, the average value of the evaluators is taken, the evaluation items of the persistence are expressed in percentage form, the initial is 100%, the evaluation results of the glossiness, the color saturation and the freshness are shown in table 4, and the evaluation results of the persistence are shown in table 5:

TABLE 4

TABLE 5

As can be seen from the results of the civil investigation, the lip gloss, the color saturation, the water wettability and the persistence of the volunteer coated with the paint light mirror surface color-retaining lip glaze are obviously improved. This is sufficient to show that the lip glaze of the present invention has the glossiness and high color saturation of the all-oil type and water-in-oil type lip glazes, and at the same time, has higher water-wettability than the water-in-oil type lip glazes and the all-oil type lip glazes.
