Description

Lip composition with plumping and moisturizing effects and preparation method and application thereof

Technical Field

The invention belongs to the field of cosmetics, and particularly relates to a lip composition and a preparation method and application thereof, in particular to a lip composition with plumping and moisturizing effects and a preparation method and application thereof.

Background

The lips usually have a rough surface, including fine lines and crevices, which detract from the smooth, elegant appearance desired by most users. Also, with age, the lip skin becomes thinner and drier. For many cosmetic formulations, it is desirable to make certain portions of the skin, especially the lips, look fuller. Reducing or at least hiding wrinkles and/or the appearance of wrinkles on the lips is an important function of cosmetic lip compositions and a continuing need for consumers, where traditional lip formulations typically fill to achieve this effect.

Meanwhile, the lips are only used as mucosa tissues exposed outside the whole body for a long time, and the thickness of the lips is only 1/3 of the skin of the body, so the lips are very fragile, delicate and sensitive to the external environment. It has no sweat gland and sebaceous gland, can not secrete grease by itself, so that it lacks a natural protective film, so that it is easy to lose moisture and dry, chap and peel in dry and windy environment. It has no pigment, and is easily damaged by ultraviolet ray, so that the lips are dull. With age, the amount of collagen in the stratum corneum of the skin of the lips is also reduced, the skin becomes loose, and the cheilogramma deepens and increases. Therefore, care and beautification of the lips is not negligible.

CN107997992A discloses a lip plumping velvet lipstick and a preparation method thereof, the lip plumping velvet lipstick comprises polyethylene, ozokerite, beeswax, ethylhexyl palmitate, hydrogenated polyisobutene, tridecyl alcohol trimellitate, titanium dioxide and the like, and although the effect of lip plumping can be achieved to a certain extent, the effect is not obvious in a short time, the effective period is long, and the moisturizing effect on lips is not good.

CN102302431A discloses a lipstick containing sheep colostrum fat and a preparation method thereof, wherein the lipstick containing sheep colostrum fat comprises the following raw materials, by weight, 1-10% of mink oil, 1-10% of glyceryl monostearate, 1-10% of glycerol, 1-5% of lanolin, 1.5-4% of stearic acid, 0.5-2% of triethanolamine, 0.1-5% of sheep colostrum fat, 0.2-1.5% of royal jelly, 0.1-1.5% of cream essence, and the balance of water. According to the lipstick, water in raw materials is locked on the lips through the oil phase component to achieve the effects of plumping and moisturizing, but volatile grease and water are easy to lose with time, and the effects of moisturizing and plumping the lips are gradually weakened.

Therefore, the development of a lip cosmetic which takes effect quickly and can exert the effects of fullness and moisturization for a long time is the focus of current research in the art.

Measurement of moisturizing Effect

With respect to the lip composition having plumping and moisturizing effects provided in examples 1 to 10 and the lip composition prepared in comparative examples 1 to 5, the moisture content of the skin was quantified by a change in conductivity based on the moisture content of the epidermis using a skin moisture tester (Corneometer), and the moisturizing rate was measured at three time points of 0h (immediately after application), 2h and 4h using a TEWL transepidermal water loss rate meter (Tewameter). Before applying the test materials, the electrical conductivity of lips was measured, and the electrical conductivity and TEWL of the lip compositions prepared in examples 1 to 10 and the lip compositions prepared in comparative examples 1 to 5 were measured, and the specific test results are shown in table 3 below.

TABLE 3

The above test data show that the conductivity of the lip composition with plumping and moisturizing effects prepared in examples 1 to 10 can reach 38% or more immediately after being applied (0h), 35% or more after 2h, and 32% or more after 4 h; the moisture retention rate can reach more than 58% after 0h, is still more than 55% after 2h, and is more than 54% after 4 h. The fact that the components of the lip composition with the plumping and moisturizing effects are mutually promoted can quickly moisten the skin of the lips and lock the moisture of the skin, is mild and non-irritant, cannot cause any adverse reaction, cannot bring any burden to the skin, and has a synergistic effect and an obvious moisturizing and synergistic effect.

Test of volumizing Effect

Selecting 160 healthy volunteers, wherein 80 male volunteers and 80 female volunteers are 80 years old, have no serious system diseases, immunodeficiency or autoimmune diseases, have no allergy to cosmetics, have no acute inflammation on the face, do not use hormone drugs or immunosuppressants, do not participate in other clinical tests, are not coated with external preparations, are randomly divided into 16 groups, 10 people in each group are used as a blank group, the rest 15 groups are respectively coated with the lip composition with the plumping and moisturizing effects provided by the embodiments 1-10 and the lip composition prepared by the comparative examples 1-5, lip balms are respectively coated on the lip skins of the volunteers in the group, and the effect of the lip skin of the volunteers is detected after 2 hours.

The skin elasticity of the lips was measured using a skin moisture meter, and the result was expressed as the ratio of the springback value Ur to the maximum tensile value Uf of the skin, and the closer the value to 1, the better the skin elasticity. Measuring wrinkle of lip skin with skin wrinkle tester, and calculating average roughness R of skin before and after lip mask cream application₃(i.e., R measured for 5 segments of the same length₁Taking the arithmetic mean of the values, R₁Represents the distance between the peak and the lowest value within a certain length, μm), the result is expressed in Δ R₃(i.e., the difference between the average roughness of the skin before and after the lip balm application) indicates that the higher the value, the better the wrinkle improvement effect. The same lip position was photographed using a skin image analyzer to determine the thickness change (μm) of the lips after using the lip balm, and the lip color change was determined using a spectrophotometer (L value indicates the degree of skin blackness, the larger L, the whiter the skin, the difference Δ L between the degree of skin blackness after using the lip balm and before using the lip balm can reflect the change of skin blackness), and the specific test results are shown in table 4:

TABLE 4

From the above test data, it can be seen that the lip compositions prepared in the embodiments 1 to 10 can effectively improve the lip elasticity parameter to be more than 0.79 and closer to 1, the average roughness change of the lips is more than 40 μm, the lip color change (Δ L) is more than 3, and can effectively improve the lip brightness, and the coating layer after being coated with the lips is wetted by the moisture in the air and the water-absorbing polymer in the composition by the saliva to achieve the expansion effect, so that not only can the lip brightness be effectively improved, the lips are moist, compact and elastic, and the phenomena of dry cracking and dull color of the lips are effectively avoided, but also the lip thickness can be effectively improved, and the lips are more beautiful.
