Description

Lip cosmetic composition emulsified as water-in-oil type comprising a water-soluble polymer

The present invention relates to a water-in-oil formulation lip cosmetic composition using a water-soluble polymer, and more particularly, stabilizing the water-soluble polymer without an emulsifier in the oil phase to provide sufficient lip volume improvement effect through the water-soluble polymer, while at the same time exhibiting excellent glossiness. It relates to a lip cosmetic composition that has good adhesion to the skin and has no stickiness and excellent feeling of use.

Recently, women are increasingly interested in cosmetics that reduce wrinkles on the skin, and in particular, interest in products that can give lips a voluminous, plump, and sexy appearance with different physiological, physical, and biological properties from the skin. is increasing Due to these demands, plastic surgery is sometimes performed, but more and more people are trying to solve it through cosmetics in consideration of cost and physical pain. As the number of consumers who want to solve these needs in cosmetics increases, research on products that make lip volume and lip contour clear are being actively conducted, and related products are coming out one after another.

In general, cosmetics for lips, which have a lip-plumping or wrinkle improvement effect, are made by mixing an oily base with waxy substances, and the components can be divided into several categories as follows. First of all, it contains wax components that maintain the appearance of the cosmetic composition for lips by increasing the hardness, such as candelilla wax, ceresin, carnauba wax, paraffin, wood wax, brazing wax, beeswax, microcrystalline lead and polyethylene, etc. Second, it contains liquid oily ingredients such as jojoba oil, squalane, lanolin oil, lanolin derivatives, oils extracted from animals and plants, synthetic ester oil, and silicone oil. Moisturizing ingredients and antioxidant ingredients are blended, fourthly, it contains organic and inorganic pigments, fifthly, it contains antioxidants, preservatives, flavoring agents and nutrients, and sixthly, it contains other ingredients such as pearl pigments. is added

On the other hand, the known material providing the plumping effect is a warming agent that provides a warming effect, polyalcohol, red pepper powder, red pepper flavor, red pepper juice, capsaicin, homocapsaicin, homodi Hydrocapsaicin, nonanoyl vanillyl amide, nonanoic acid vanillyl ether, vanillyl alcohol alkyl ether derivatives (Japanese Patent Laid-Open No. 57-9729), isovanilyl alcohol alkyl ether, ethylvanillyl alcohol alkyl ether, veratril Alcohol derivatives, substituted benzyl alcohol derivatives, substituted benzyl alcohol alkyl ethers, vanillin propylene glycol acetal, ethylvanillin propylene glycol acetal, ginger juice, ginger oil, gingerol, gingeron, hepatica, cinnamon, ginger , rosemary and niacin components, and the like, and substances other than the warming agent include palmitoyl oligopeptide (Pal-GHK) and collagen components.

However, there is a problem that the ingredients exhibiting such a lip-plumping effect irritate the lips when used and have a strong stickiness.

On the other hand, in the existing cosmetic compositions for lips, oil-soluble polymers have been mainly used in order to exhibit a glossy effect. However, when the oil-soluble polymer is used, there is a disadvantage that the stickiness is severe and there is a feeling of suffocation.

In addition, when a water-soluble polymer is used, the hardness of the stick is lowered when the formulation is a lipstick, the compatibility between the components of the lipstick is remarkably deteriorated, the oil is separated from the lipstick, and the appearance of the stick is messy, and the water-soluble component The risk of skin irritation was high due to various emulsifiers used for the emulsification of . In addition, Korean Patent Registration No. 10-1221270 (announced on January 11, 2013) discloses a lipstick to which an emulsified base containing a water-soluble polymer is applied, but the lipstick has a dual structure composed of a cylindrical core and a shell surrounding the core. It does not disclose its use in a single formulation as a lipstick of

1) Evaluate the effect of improving gloss and lip volume

Example 1, as a 24-35 year old female with at least 2 years of makeup experience, was applied to the lips by each of 20 professional panelists who continuously use lip products at least 5 times a week, and then immediately after application and after 15 seconds were compared. Each state was recorded by taking a picture, and the results for one of them are shown in FIG. 1 .

Referring to FIG. 1 , it can be seen that when 15 seconds elapse after application of the composition, glossiness is higher than immediately after application, and lip volume is improved.

In addition, the Examples 1 and 2 and Comparative Examples 1 to 3 were applied to the lips by 20 professional panelists who are 24-35 year old women with at least 2 years of makeup experience and who continuously use lip products at least 5 times a week. Next, the state after 15 seconds of application was compared. Each state was recorded by taking a picture, and the results for one of them are shown in FIG. 2 .

Referring to FIG. 2, it can be seen that Examples 1 and 2 of the composition have improved lip volume compared to Comparative Examples 1 to 3.

2) Glossiness evaluation

The glossmeter of the lipsticks prepared according to the compositions of Examples 1 to 5 and Comparative Examples 1-3 was tested using a Glossmeter (Gardner).

The measurement method is to measure the glossiness by applying a lipstick prepared according to the composition on a gloss measuring paper 5 times with a constant force and then measuring the amount of reflection when light is irradiated on the application surface at a reflection angle at a 60 degree angle using a glossmeter. The glossiness is shown in Table 1 (average value after 3 measurements). The higher the numerical value shown in the results of Table 3 below, the better the gloss.

3) Lip wrinkle masking effect (pack effect)

After applying the lipstick prepared on artificial leather 5 times with a constant force, the degree of boneiness was evaluated by taking pictures.

The measurement results for this are shown in FIG. 3 .

Referring to FIG. 3, when Comparative Examples 1 to 3 are applied, the valleys are seen as they are, but when Examples 1, 4 and 5 are applied, in particular, when Example 1 is applied, it can be confirmed that the valleys are almost completely filled. It can be seen that, when applied to the lips, the lip wrinkles are masked to obtain an effect similar to that of the lip wrinkle.

3) Evaluation of glossiness, volume, non-stickiness, adhesion and wrinkle masking

Examples 1 to 5 and Comparative Examples 1 to 3 were used on the lips by 20 professional panelists who were women aged 24-35 years old, who had at least 2 years of makeup experience, and who continuously used lip products at least 5 times a week. Afterwards, each item was compared and evaluated on a 5-point scale (1 point: very poor, 3 points: average, 5 points: very good).

The evaluation result was scored out of 5 points (1 point: very bad; 2 points: bad; 3 points: average; 4 points: good; 5 points: very good) to obtain an average score, which It is shown in Table 4 below.
