Description

Cosmetics

The present invention relates to cosmetics. More specifically, the present invention relates to a transparent or translucent cosmetic that is excellent in preparation stability and speed of familiarity with the skin.

Skin cosmetics such as lotion are used for the purpose of imparting appropriate moisture to the skin and keeping the skin healthy. Moisturizers are widely used as moisturizing ingredients, but cosmetics that contain a relatively large amount of water in addition to the moisturizer have a low affinity for the skin when applied and tend to be repelled on the skin. There was a problem that the feeling of penetration was bad. Conventionally, in addition to the method of adding ethanol, dextran or a dextran derivative is blended (Patent Document 1), a water-in-oil cosmetic dosage form is selected (Patent Document 2), and raffinose. A method of combining a certain amount and agar (Patent Document 3) has been adopted. However, these conventional methods have problems such as safety concerns (skin on skin, etc.), alcohol odor, insufficient effect, and limited dosage form options.

By the way, especially in the case of water-based skin cosmetics, those having a translucent to transparent appearance tend to be preferred. For example, a method using an emulsifier or a solubilizing agent (for example, a nonionic surfactant) is used to make a translucent to transparent cosmetic. However, at present, sufficient effects can be obtained in terms of penetrating feeling. difficult.

Therefore, there is a demand for cosmetics that have a translucent to transparent appearance, satisfy usability (fastness to skin), and have excellent formulation stability.

In addition, the average value which divided the sum total of the score by each panel by the panel number of persons was calculated, and it was set as the evaluation result according to the following evaluation criteria.
(Scoring criteria)
+3: Very familiar to skin compared to control sample +2: Faster to skin compared to control sample +1: Slightly familiar to skin compared to control sample 0: -1: Slightly familiar to the skin compared to the control sample -2: Slowly adapted to the skin compared to the control sample -3: Slightly adapted to the skin compared to the control sample Familiarity is very slow (evaluation criteria)
◎: The average value of 10 panelists is +2.0 or more ○: The average value of 10 panelists is 0.5 or more and less than 2.0 points △: The average value of 10 panel members is −1.5 points or more Less than 0.5 points x: The average value of 10 panelists is less than -1.5 points

Example 1
Samples 1 to 20 shown in Tables 1 and 2 below were prepared. Each sample was prepared by mixing the components corresponding to (1) to (11) and separately adding this to the mixture of (12) and (13).

Using the obtained samples, according to the above evaluation methods, the transparency, the stability of the preparation, and the speed of familiarity with the skin were evaluated. The results are shown in Tables 1 and 2. As described above, since the evaluation of the speed of familiarity with the skin was performed with reference to the sample 1, the evaluation of “the speed of familiarity with the skin” of the sample 1 in Table 1 is “ -".

In Tables 1 and 2, “(a) component ^{(* 1)} ” (= (a) -8) is a silicone surfactant represented by the above formula (I) (wherein R ₁ is a methyl group, R ₂ is Methyl group, k = 8 is used). “(A) component ^{(* 2)} ” (= (a) -17) is a silicone surfactant represented by the above formula (I) (wherein R ₁ is a methyl group, R ₂ is a methyl group, k = 17) Was used). As the “(b) component ^{(* 3)} ”, a nonionic surfactant represented by the above formula (II) (wherein R ₃ represents a 2-decyltetradecyl group, m = 13, n = 24) was used. .

As is clear from the results in Tables 1 and 2, Samples 7 to 20 that satisfy the constituent requirements of the present invention have excellent effects in all of translucency to transparency, formulation stability, and speed of familiarity with the skin. It was. On the other hand, Samples 1 to 6 that do not satisfy the constituent requirements of the present invention could not have all the effects of the present invention. For example, sample 1 did not contain both component (a) and component (b), and the formulation stability and the speed of familiarity with the skin were not sufficient. Sample 2 contained the component (b) but did not contain the component (a), and the speed of familiarity with the skin was not sufficient. In Sample 3, the component (a) was included but the component (b) was not included, a transparent or translucent appearance was not obtained, and the formulation stability was poor. In sample 4, when other nonionic surfactant was used instead of the component (b), a transparent or translucent appearance was not obtained, and the preparation stability was not sufficient. In samples 5 and 6, when other silicone surfactant was used instead of component (a), the speed of familiarity with the skin was not obtained.
