Description

  TECHNICAL FIELD The present invention relates to a skin cleansing composition having excellent overall suppression of wet feeling on washed skin, moisturizing feeling and soft feeling.

  Various skin cleansing compositions such as facial cleansers, body soaps, and shampoos have been provided as products intended to clean the skin and keep the skin clean. In the mechanism by which the skin cleansing composition cleans the skin, a surfactant is indispensable. Surfactants used in the skin cleansing composition include anionic surfactants, nonionic surfactants, amphoteric surfactants, and the like. In particular, anionic surfactants are used in many skin cleansing compositions because of their excellent detergency and good flushability. On the other hand, in view of skin irritation caused by anionic surfactants, various skin cleansing compositions containing a surfactant other than anionic surfactant as a main surfactant have been proposed. In these skin cleansing compositions, a component that supplements washability and the like may be blended by replacing the anionic surfactant with another surfactant.

  For example, Patent Literature 1 discloses a detergent composition containing a polyoxyethylene alkyl ether acetic acid having a neutralization ratio of 30 to 70% and an N-acylglutamate or an N-acylaspartate. It is described that an excellent feeling of use (no refreshing feeling, no slimy feeling) was obtained by a make-up remover facial wash that was prepared specifically. In Patent Document 2, a liquid nonionic surfactant having an HLB value of 5.5 or less, a nonionic surfactant having an HLB value of 8 or more, oil, water, an amphiphilic substance, a monohydric alcohol, and a polyhydric alcohol are disclosed. A transparent cleansing cosmetic containing one or two or more water-soluble components selected from the group consisting of alcohols and alkylene oxide derivatives at a specific content is disclosed, and specifically prepared make-up remover, cleansing It is described that an excellent cleansing effect, a feeling at the time of use, ease of washing, and a refreshing feeling after use are obtained by removing the oil and the eye makeup.

JP-A-6-25695 JP 2014-152108 A

  The cleaning composition disclosed in Patent Literature 1 and the cleansing cosmetic disclosed in Patent Literature 2 achieve a suppression of slimy feeling (easy to wash off), but a refreshing feeling after use. Since the emphasis is placed on the skin, the moisturizing feeling and the soft feeling on the skin after use are easily lost. In other words, the conventional skin cleansing compositions have not been able to achieve the same level of moisturizing feeling and softness as to suppress the sliminess of the skin after use, and have not been excellent in overall feeling of use.

  Therefore, an object of the present invention is to provide a skin cleansing composition which is excellent overall in terms of the suppression of slimy feeling on the washed skin, the moisturizing feeling, and the soft feeling.

  As a result of intensive studies, the present inventor has found that, in a skin cleansing composition, an amphipathic ester and a cationized hyaluronic acid and / or a salt thereof are blended together with an amino acid-based surfactant, so that the washed skin becomes wet. It has been found that, while suppressing the sticking feeling, a moisturizing feeling and a soft feeling are also exhibited well. The present invention has been completed by further study based on this finding.

That is, the present invention provides the following aspects of the invention.
Item 1. A skin cleansing composition comprising (A) an amino acid-based surfactant, (B) an amphiphilic ester, and (C) a cationized hyaluronic acid and / or a salt thereof.
Item 2. Item 2. The skin cleansing composition according to item 1, wherein the component (B) is selected from the group consisting of a dicarboxylic acid bis (polyoxyalkylene alkyl ether) ester and (eicosane diacid / tetradecane diacid) polyglyceryl-10.
Item 3. Item 3. The skin cleansing composition according to Item 2, wherein the dicarboxylic acid bis (polyoxyalkylene alkyl ether) ester is cyclohexane-1,4-dicarboxylic acid bisethoxydiglycol.
Item 4. Item 4. The skin cleansing composition according to any one of Items 1 to 3, wherein the component (C) is hydroxypropyltrimonium hyaluronate.
Item 5. Item 5. The skin cleansing composition according to any one of Items 1 to 4, further comprising (D) lecithin and / or lysolecithin.

Without applying any friction, cleaning can be performed only by utilizing the mechanical force of the liquid flow. Since the skin cleansing composition of the present invention is a formulation with low irritation and excellent detergency, it can be washed by using the mechanical force of the liquid flow without giving physical friction in this manner, The burden on the skin is remarkably reduced, and a very gentle cleaning method becomes possible. In addition, the skin cleansing composition of the present invention is particularly suitable for a cleaning method that does not impart physical friction to the skin as described above, but using a hand or the like after applying the skin cleanser composition to a site to be cleaned. It does not exclude the use of rubbing.

  The site to be washed with the skin cleansing composition of the present invention is not particularly limited because it can wash any body part, and includes, for example, hands, hair, scalp, body, face and the like. In particular, since the skin cleansing composition of the present invention is excellent in suppression of slimy feeling on washed skin, moisturizing feeling, and softness, it is suitable for use on a face where these feelings are particularly easily felt. is there.

  After washing, the skin cleansing composition can be washed away with water. When washing with water, washing may be performed in the same manner as in 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 stream to wash away without applying friction by hand.

<Evaluation of slimy feeling suppression>
About the prepared skin cleanser composition, 10 panelists specialized in cosmetics evaluation evaluated the slimy feeling at the time of washing. Specifically, each skin cleansing composition was contained in a pump type spray container (“Z-155-C110 (trade name)” manufactured by Takemoto Container Co., Ltd. (the injection amount per push was 0.15 g). 0.5 g was applied by spraying directly on the face, left for about 5 seconds, and then rinsed with water.After rinsing, the sliminess of the skin was measured based on the following index without wiping off the water. evaluated.
4 points: No sliminess 3 points: Not much slickness 2 points: Slightly slick 1 point: Slightly slim

The obtained scores of 10 panelists were totaled, and the degree of slimy feeling suppression was evaluated according to the following classification. The results are shown in Tables 1 to 4.
◎: 37 points or more
○: 33 points or more and less than 37 points
△: 30 points or more and less than 33 points
×: less than 30 points

<Moist (moisturizing) evaluation>
About the prepared skin cleanser composition, 10 panelists specialized in cosmetics evaluation evaluated the moist feeling (moisturizing feeling) at the time of washing. Specifically, each skin cleansing composition was contained in a pump type spray container (“Z-155-C110 (trade name)” manufactured by Takemoto Container Co., Ltd.

  As shown in Tables 1 to 4, a skin cleansing composition containing (A) an amino acid-based surfactant, (B) an amphiphilic ester, and (C) cationized hyaluronic acid and / or a salt thereof (Example 1) Nos. 16 to 16) were excellent overall in terms of the suppression of slimy feeling on the washed skin, the moisturizing feeling, and the softness. On the other hand, for example, the skin cleansing compositions (Comparative Examples 5, 6, 17 to 22) containing the component (a) (other surfactant) without the component (A) have a moisturizing feeling and a soft feeling. Was inferior. Further, the skin cleanser compositions containing no component (B) (Comparative Examples 1, 2, 9 to 12, 15, 16) were particularly inferior in moisturizing sensation. Further, the skin cleanser compositions containing no component (C) (Comparative Examples 3, 4, 11 to 16) are inferior in moisturizing feeling and soft feeling, and further contain component (c) (another cationic polymer). With the added skin cleansing composition (Comparative Examples 7, 8, 23 to 25), a moist feeling was generated instead of improving the moisturizing feeling and the soft feeling.
