Description

Technical Field

[0001] The present invention relates to a cosmetic composition that has good skin affinity, excellent moisturizing effect, no sticky feeling, and excellent usability.

Background Art

[0002] Conventionally, cosmetics aimed at moisturizing the skin and preventing dryness contain glycerin and 1,3-butylene glycol, which are representative examples of humectants. Further, in order to enhance the moisturizing effect, attempts have been made to blend various humectants such as water-soluble polymers and amino acids.

[0003] In recent years, various effects such as whitening effect in addition to the moisturizing effect are often required for cosmetics and the like. As the usability for continuing to use cosmetics and the like, the feeling of familiarity with the skin and the lack of stickiness are emphasized.

[0004] However, increasing the content of the humectant to enhance the moisturizing effect often leads to an unfavorable usability that the skin affinity deteriorates and a sticky feeling occurs. In addition, there is a problem that a sticky feeling occurs also due to the blending of the whitening component.

[0005] For example, in Patent Document 1, it is proposed to achieve both a moisturizing effect and a reduction in stickiness by emulsifying a polyhydric alcohol, an organic acid salt, and a low-viscosity silicone oil with an alkyl-modified carboxyvinyl polymer, but there are problems to be solved that the skin affinity and the moisturizing effect are not always sufficient.

[0006] In addition, in Patent Document 2, it is disclosed that the stickiness caused by tranexamic acid, which is a whitening component, can be reduced by blending xanthan gum or glycerin, and certain improvements have been made, but the current situation is that characteristics that are still fully satisfactory have not been obtained.
