Description

[0001] Cosmetic composition for lip [0002]

The present invention relates to a lip cosmetic composition, and more particularly, to a water-in-oil type lip cosmetic composition that exhibits lingual moisture perception and volume control effect.

The cosmetic composition for lips provides beauty by giving bright color to the lips. Applying a product using a general underwater type lip cosmetic composition to the lips can provide an immediate hydration feeling, but the moisture can evaporate quickly, giving the product a drier feel than before, and it can be easily adhered to a cup or clothes . In addition, the lipid cosmetic composition of general oil-dispersed form is characterized in that the pigment is dispersed in an oil-based base such as vegetable, vegetable and ester oils and the mixture is mixed with waxy substances, and the product has poor color sustainability and tackiness, stiffness, lack of moisture And is easily erased.

Various attempts have been made to solve such a problem, and such attempts will be described as follows. The method using volatile oil was able to improve durability and function not to be easily stained in cups or clothes, but it gave a feeling of dryness of the lips, and the method of forming a film on the lips by using the acrylic polymer was relatively insufficient in adhesion and persistence The lips were given a heavy cosmetic effect, and a large amount of porous powder was added to a large amount of oil to reduce the amount of residue and increase the sustainability. However, I did not. In addition, a method using a water-in-oil type (Patent Document 1) has been tried in an effort to prevent moisture evaporation due to an oily component, but the above method has a problem that a sorbitan derivative or the like is used to cause skin irritation.

In order to solve the above-mentioned problems, the present applicant has proposed a stable water-in-oil type lip that can improve the moisture feel of the lips by using the raw material for forming the film on the lips at an optimal ratio within the formulations, The present invention has been completed.

Hereinafter, the present invention will be described in more detail based on the following examples. However, the following examples are illustrative of the present invention but are not limited thereto.

(Examples 1 to 3) Preparation of Lip Gloss

In the composition shown in Table 1, raw materials 1 to 2 were charged into a reactor, stirred for 10 minutes while being heated to 95 ° C, and then added with the raw materials 3 to 6, followed by stirring at 90 ° C for 10 minutes. Thus, the raw material 7 was charged and stirred at 90 캜 for 15 minutes to prepare an oil phase. The raw materials 8 to 10 were added to another reactor, and the mixture was stirred and padded for 10 minutes while being heated to 80 ° C. The raw materials 11 were further added and stirred for 5 minutes to prepare an aqueous phase. After the water phase was added to the oil phase, the oil phase was emulsified for 20 minutes without heating and then the raw material 12 was added. The temperature of the reactant was lowered to 30 캜 and then degassed to prepare a lipgloss.

(Comparative Examples 1 to 5) Preparation of lipgloss

Lip Gloss was prepared in the same manner as in Example 1 with the composition shown in Table 2 below.

As a result, in the case of Comparative Examples 4 and 5 prepared by the above-described method, it was confirmed that phase separation occurred within 24 hours after the formulation was formed because the emulsifying power was remarkably reduced.

The evaluation of each of the lipglosses prepared in Examples 1 to 3 and Comparative Examples 1 to 3 was carried out as follows. The results are shown in Tables 3 to 4 below.

1. Moisture evaluation

The amount of water (TEWL) transepidermal water loss from the inside of the skin through the skin was measured using an evoporimeter-EP1. The skin was treated with acetone to destroy the stratum corneum, the TEWL before the treatment of the product was measured, and the TEWL after 30 minutes from the treatment of each lip gloss was measured.

The results are shown in Table 3 below. The measured TEWL change value (DELTA TEWL) means that the smaller the value, the better the moisture retention.

2. Feeling of feeling

Each of the lipglosses prepared in Examples and Comparative Examples was applied to 20 women three times, and their preferences for rubbing, shine, moisturizing and volume feeling were evaluated. The results are shown in Table 4 below. Individual items were evaluated with a score of 10.

As shown in Tables 3 to 4, the lip cosmetic composition according to the present invention shows remarkably improved water retention and excellent spreadability. In addition, the cosmetic composition for lips according to the present invention is excellent in luster and volume, so that it is possible to optimize the lip-plumping effect without irritation on the lips.
