Description

Skin cleansing material composition

The present invention relates to a skin cleansing composition having excellent comprehensiveness of smoothness, moisturizing, and softness of the skin after washing.

As products aimed at cleansing the skin and keeping the skin clean, various skin cleansing ingredients such as facial cleanser, body soap, and shampoo are provided. For the skin cleansing composition, in addition to good foaming and good cleaning power, a good feeling of use is required.

As one of the good feelings of use, the smoothness (smoothness) of the skin is a characteristic that feels good after washing, so it is particularly important. For example, Patent Document 1 describes the cleaning agent composition containing fatty acid soap, amphoteric surfactant, or alkanolamide-type nonionic surfactant, vine (Kutong) or milk vetch extract after cleaning The skin's firmness and smoothness are excellent. Patent Document 2 describes that it contains a fatty acid salt, a isethionic acid salt, and at least one selected from waxes, hydrocarbons, and glycerides with a melting point of 30°C to 100°C, that is, solid fats. The solid cleaning agent composition of the product has excellent smoothness during washing. Patent Document 3 describes that a skin cleansing composition containing an anionic surfactant, an alkyl ether carboxylic acid or its salt, 2-ethylhexyl glyceryl ether, and water has excellent smoothness of the skin after cleansing.

As a particularly good use aspect, it can be stored in a spray container, a pouring or dripping container (especially a washing bottle), preferably a spray container, without the skin cleanser composition. Apply directly to the area to be cleaned. In the case where the skin cleansing agent composition is directly applied to the cleansing target area in the manner described above, it is possible to avoid friction between the skin and hands of the cleansing area or between the skin and air bubbles in the cleansing area. In the case of physical friction such as generated friction, only the mechanical force of the liquid flow is used for cleaning. The skin cleansing composition of the present invention is a formula with low irritation and excellent cleansing power. Therefore, by using the mechanical force of the liquid flow to clean without causing physical friction in the manner described, the burden on the skin is significantly reduced during cleansing , Can achieve an extremely excellent cleaning method. Furthermore, the skin cleansing composition of the present invention is particularly suitable for the above-mentioned cleansing methods that do not cause physical friction on the skin, but it does not rule out that the skin cleansing composition is applied to the area to be cleaned and then rubbed with hands. Instructions.

The cleansing target part of the skin cleansing composition of the present invention is not particularly limited because it can clean all body parts, and examples thereof include hands, hair, scalp, body, and face. In particular, the skin cleansing composition of the present invention is excellent in smoothness, moisturizing, and softness of the skin after washing, and is therefore suitable for use on a face where these feelings of use are particularly easily felt.

After washing, the skin cleanser composition can be washed with water. In the case of washing with water, it is sufficient to perform the same as a normal face washing, but from the viewpoint of reducing the burden on the skin, it is preferable to use the mechanical force of the water flow to wash so as not to cause friction by hands.

＜Smoothness (smoothness) evaluation＞ For the prepared skin cleansing composition, 10 panelists specialized in cosmetic evaluation evaluated the smoothness after washing. Specifically, for each skin cleansing composition in Table 1, it was stored in a pump spray container ("Z-155-C110 (trade name)" manufactured by Takemoto Container Co., Ltd.) (the spray volume per press is 0.15 In g), apply by spraying 1.5 g directly onto the face. Leave it for about 5 seconds, then rinse with water. In addition, each skin cleansing composition in Table 2 was stored in a pump foamer container, and 1.5 g was applied to the face. Scrub for about 5 seconds, then rinse with water. There is no need to wipe off the water after rinsing, and the smoothness (smoothness) of the skin is evaluated based on the following indicators. 5 points: sufficient smoothness (smoothness) 4 points: smooth feeling (smooth feeling) 3 points: Slightly smooth (smooth feeling) 2 points: not very smooth (smooth feeling) 1 point: No smoothness at all (smoothness)
