Description

Cosmetic composition for lips comprising a water-in-oil type emulsified base {LIP COSMETIC COMPOSITION COMPRISING WATER-IN-OIL EMULSION BASE}

It relates to a cosmetic composition for lips comprising a water-in-oil type emulsified base.

In general, lipstick provides moisture to the lips to prevent them from drying out, and wax and powder fix the color pigment so that it can be maintained on the lips for a long time. The higher the content of oil in the lipstick composition, the better the shielding film is formed and the moisturizing effect increases.

Conventional lipsticks have reduced the stuffy and heavy feeling of use by using volatilization type, silicone oil with low viscosity, porous powder, etc. to develop a lipstick with a light and moist feeling. However, when a large amount of volatile oil or porous powder is used, the moisturizing feeling of the lips is deteriorated and the compatibility between the lipstick components is lowered, so that the stick may be broken or the oil may be separated from the lipstick, causing sweating of the appearance of the lipstick. A technology that can contain moisture in the lipstick is necessary for moisturizing while giving a refreshing feeling of moisture at the first touch of the lipstick.

Under this technical background, research on lipsticks with both moisturizing and freshness is being actively conducted (KR Publication No. 10-2017-0025647), but it is still incomplete.

The present invention is to provide a cosmetic composition for lips comprising a water-in-oil type emulsified base comprising beeswax, ozokerite and disteadimonium hectorite.

One aspect provides a cosmetic composition for lips, which includes a water-in-oil emulsified base comprising beeswax, petroleum-based and synthetic wax, and disteadimonium hectorite.

The beeswax is a natural wax, also referred to as beeswax, and may refer to animal-based solid wax that is collected from a honeycomb by a heat compression method, a solvent extraction method, or the like.

The water-in-oil type emulsified base is one or more petroleum and synthetic waxes selected from the group consisting of ozokerite, ceresin, montan wax, paraffin, microcrystalline wax, emulsifying wax, synthetic wax, and synthetic beeswax in addition to beeswax. may further include. This is because, when only beeswax having a low hardness value is used, the viscosity is relatively low and separation at high temperature occurs.

Another aspect is to provide a cosmetic composition for lips, wherein the mixing weight ratio of the beeswax and disteadimonium hectorite is 5: 1 to 1: 1.

The mixing weight ratio may be preferably 4:1 to 1:1, 3:1 to 1:1, and 2:1 to 1:1.

When only disteadimonium hectorite is added alone without containing a wax component to increase the viscosity, when 2% or more is used, the viscosity becomes excessively high and the stability of the emulsion composition is rather deteriorated, and this is contained in the oily stick phase When this is done, the viscosity increases together, and molding at a high temperature (about 80℃) becomes difficult.

Another aspect is to provide a cosmetic composition for lips, which comprises 10 to 35% by weight of the water-in-oil type emulsified base based on the total weight of the cosmetic composition. The weight may be 10 to 40, 10 to 30, 15 to 25, 10 to 20% by weight based on the total weight of the cosmetic composition.

In the present invention, it is preferable to use an emulsifier having a low HLB value and a low hydrophilicity ratio for the water-in-oil type emulsification base in the present invention. It may be characterized by containing two or more emulsifiers from the constituent group that helps emulsify, such as sorbitan olivate. First, by preparing an emulsified base in which the emulsified state is stabilized, the moisture and moisturizing agent content can be variously adjusted, and a feeling of use can be imparted by adding it to the solid stick base without a separate secondary emulsification process.

Another aspect provides a cosmetic composition for lips, which comprises 0.1 to 5% by weight of beeswax, 0.1 to 3% by weight of disteadimonium hectorite, based on the total weight of the cosmetic composition or the total weight of the water-in-oil type emulsion base will be.

The weight of the beeswax may be preferably 0.1 to 4, 0.1 to 3, 0.1 to 2, 0.1 to 1.5% by weight, and the weight of disteadimonium hectorite is preferably 0.1 to 2, 0.1 to 1 weight. It can be %.

Another aspect provides a solid cosmetic composition for lips to which the water-in-oil emulsion base is added. The solid cosmetic composition for lips may include wax, oil, powder, pigment, and a water-in-oil type emulsified base.

The oils include caprylic/capric triglyceride, coco-caprylate/caprate, hydrogenated polyisobutene, diisostearylmalate, propylene glycol dibenzoate, squalane, octyldodecanol, and at least one oil selected from the group consisting of methylhydrogenated loginate, octyldodecanol, phenyltrimethicone and pentaerythrityltetraisostearate. Hydrogenated polyisobutene serves to suppress the evaporation of water in the emulsion formulation, so when properly formulated in the cosmetic composition, it helps to delay the volatilization of the aqueous phase.

In the present invention, the pigment can use various types of pigment formulations, such as dicalcium phosphate, alumina, mica, silica powder or titanium dioxide, Red No. 201, Red No. 104, Yellow No. 4, Red No. 202, etc. It can be used by mixing|blending the pigment for coloring.

A specific manufacturing method of the lipstick is as follows. The wax and oil raw materials of Table 2 are measured and heated to 90° C., the pigment and powder are added and mixed with a mixer, while the water-in-oil emulsified base is added at 80° C., and then mixed again. After 5 minutes, the mixing is finished, defoaming, and then lipstick molding. Among the components, polyethylene is a material for adjusting hardness according to the amount of the water-in-oil type emulsified base, and does not affect the feeling of use of the lipstick.

Experimental Example 1. Evaluation of stability of water-in-oil type emulsified base

In order to check the stability of the water-in-oil type emulsified bases of Preparation Example 1 and Comparative Examples 1 to 3, put the bases in a viscosity bottle at room temperature, measure 25 ℃, immediate specification and 1DAY specification value, and observe for 7 days in a 50 ℃ thermostat and its stability was evaluated. The results are shown in Figure 1 and Table 2.

Preparation Example 1 Comparative Example 1 Comparative Example 2 Comparative Example 3 Initial specification (avg) 94 20 48 70 1Day Standard (Avg) 109 11 74 76

As a result of confirming the standard values of the Preparation Examples and Comparative Examples, in the case of Preparation Example 1 and Comparative Examples 2 and 3 except for Comparative Example 1, similar standard values were formed in hardness immediately after manufacturing and hardness after 1 day. In the case of Comparative Example 1, the instantaneous viscosity showed a phenomenon that the hardness decreased as time passed, and there was a problem in that the contents were separated over time at a high temperature of 50°C.

In the evaluation of the feeling of use, Comparative Example 2 showed a heavy and sticky feeling when applied due to a large amount of wax, and Comparative Example 3 had a high viscosity during the manufacturing process, significantly lowering flowability, and thus emulsification was not performed smoothly. On the other hand, in the case of Preparation Example 1 containing all of beeswax, ozokerite and disteadimonium hectorite, the initial viscosity and 1 day specification did not change much, and the use was soft and creamy, and stable fluidity even when contained on a stick It was judged that it gave a, and it was selected as the most suitable base composition.

Experimental Example 2. Confirmation of feeling of use of water-in-oil type emulsified base lipstick

After testing Examples 1 to 4 on the lips of 30 women aged 25-45, respectively, the feeling of use such as moisture, spreadability, and finish was evaluated according to the following evaluation criteria, and the results are shown in Table 4.

Example 1 Example 2 Example 3 Comparative Example 4 moisture ○ X △ ○ spreadability ○ ○ ○ △ finish △ X ○ X vitality ○ X ○ △

[Evaluation Criteria] Bad: X Normal: △ Good: ○

In the evaluation of the feeling of use in Table 4, in the case of Example 2, there were many opinions that the oil content was rather high, so that the finish was stuffy, and there was a disadvantage in that the color durability was lowered due to the glossiness. In addition, in the case of Example 4, there was a lot of moisture, so freshness and moisture could be felt a lot, but there was a review that the spreadability was rather poor due to a high melting feeling, and there was a review that there was a sticky feeling in the finish feeling. It was found that the samples of Examples 1 and 3 were generally excellent in moisture and finish, and as Example 1 contained more moisture than Example 3, it was more refreshing and thinner than conventional oil-dispersed lipsticks. It can be identified as a composition having the most suitable weight in the above patent.
