Description

The present invention relates to an oil-in-water emulsified cosmetic.

2. Description of the Related Art Conventionally, there have been known skin cosmetics that give the skin a moisturizing feeling and a firm feeling (a feeling that the skin is moderately stretched and does not sag) for the purpose of making wrinkles inconspicuous. As such an emulsified cosmetic that imparts firmness to the skin, one that contains polyethylene glycol (PEG) or a higher alcohol is known (Patent Documents 1 and 2).

JP 2012-197253 A JP-A-2005-53879

However, skin cosmetics containing PEG tend to run off the skin, making it difficult to impart sufficient firmness to the skin. In addition, skin cosmetics containing higher alcohols permeate the skin and improve the quality of the skin, and do not give a sufficiently high firmness immediately after application.

In addition, skin cosmetics such as those described above have a certain amount of weight when applied, and a feeling of use that gives a high-concentration feeling (“rich” feeling of use, also known as “rich feeling”). ) is required. The feeling of richness when the cosmetic is applied to the skin gives a feeling of using a thick agent, a sense of luxury, and a sense of expectation for further effects. You can increase your willingness to buy.

Conventionally, in order to give a rich feeling, it was common to use a method of blending a relatively large amount of oily ingredients, but in that case, it took a long time for the skin cosmetic to be absorbed after it was applied to the skin, and the skin cosmetic was used. There was a tendency for the skin to become more sticky after application of the product.

Some users, particularly those who have little experience in using skin cosmetics and male users, tend to dislike that it takes a long time to get used to skin cosmetics and that skin becomes sticky. Therefore, there is a demand for a skin cosmetic that has firmness and richness, is less sticky, and absorbs quickly.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a cosmetic that suppresses stickiness, has a rich feeling, and can impart a firm feeling to the skin when applied to the skin.
Another object of the present invention is to provide a cosmetic that suppresses stickiness, has a rich feeling, and, when applied to the skin, can quickly blend into the skin and impart a firm feeling to the skin.

EXAMPLES The present invention will be described in more detail below based on examples, but the present invention is not limited only to these examples. The amounts shown in the tables are the amounts of each component (that is, the amount of the active ingredient in each raw material), and the unit is "% by mass" unless otherwise specified. In addition, "-" in the blending amount in the table indicates that the component is not blended.

Examples 1-10, Comparative Examples 1-5
(Preparation of each sample)
Each component was blended according to the formulation shown in Table 1, a cosmetic was prepared by a conventional method, and subjected to the following evaluation tests.

(evaluation)
Three professional evaluators evaluated richness, penetration, firmness, and stickiness. The results were determined by synthesizing the evaluations of each evaluator.

<Rich feeling>
The cosmetics obtained in Examples and Comparative Examples were applied to the inner part of the forearm, and the applied part was rubbed back and forth with a hand so that it was absorbed. Based on the feel of the product up to three reciprocations after application, the "rich feeling" was sensory evaluated according to the following evaluation criteria. Evaluation results are shown in Table 1.
⊚ (excellent): A sticky weight is felt when spread on the skin, and the feel of high concentration is strong.
◯ (good): When spread on the skin, the weight is clearly felt, and the feeling of high concentration is felt.
Δ (can be used): Slightly heavy feeling when spread on the skin, slightly high-concentration feel.
x (poor): No feeling of weight or high density when spread on the skin.

<Sense of Penetration>
In addition, the feeling of penetration was sensory-evaluated according to the following evaluation criteria, based on the change in touch feeling until the application area no longer felt slippery due to the cosmetic and the cosmetic blended into the skin. Evaluation results are shown in Table 1.
⊚ (excellent): It is felt that the cosmetic is familiar to the skin by 10 reciprocations.
◯ (good): It is felt that the cosmetic material is absorbed into the skin after 11 to 15 reciprocations.
(triangle|delta) (usable): Although a slight sliminess of cosmetics remains at the time of 15 reciprocations, it is practically permissible.
x (poor): After 15 reciprocations, the cosmetic remains sticky and is not practical.

<Firmness>
In the above evaluation, after feeling that the cosmetics obtained in Examples and Comparative Examples were absorbed into the skin, the "tension feeling" was evaluated according to the following evaluation criteria based on the feel of the applied part of the skin. Evaluation results are shown in Table 1.
⊚ (excellent): There is a feeling of a film, and a clear feeling of firmness is felt.
◯ (Good): A feeling of film is present, but the feeling of firmness is slightly weak.
x (defective): No feeling of a film is felt at all.

<Sticky>
In the evaluation of <penetration feeling>, "stickiness" was evaluated according to the following evaluation criteria based on the feel of the skin at the applied area when the cosmetics obtained in Examples and Comparative Examples were absorbed into the skin. Evaluation results are shown in Table 1.
⊚ (excellent): good slipperiness is felt, and stickiness is not felt.
○ (Good): Good slipperiness is felt, but stickiness is slightly felt.
Δ (can be used): Sliding property is weak and stickiness is slightly felt.
x (defective): Stickiness is clearly felt.

In the above evaluation, all of the cosmetics of the above Examples gave a feeling of water being supplied to the skin when applied to the inside of the forearm, and felt fresh.
