Description

[Technical field]

[0001] The present invention relates to a cosmetic preparation and a moisture retention promoter for a cosmetic preparation. [Background technology]

[0002] It is known that the skin becomes easily dry due to ultraviolet rays, aging, and poor lifestyle habits. As the dryness of the skin progresses, the skin becomes rough and stiff, losing its smoothness, and can even cause a variety of skin problems such as dry fine lines, enlarged pores, and rough skin. Therefore, consumers select their favorite products and perform skin care based on the characteristic functions and feel of various moisturizers.

[0003] Patent Document 1 proposes an emulsion composition with excellent moisturizing effect and good usability by combining higher alcohol, silicone oil, fatty acid triglyceride with polyhydric alcohol or sugar alcohol, while Patent Document 2 proposes a composition with high moisturizing effect by combining saturated fatty alcohol, anionic surfactant, polyol, and silicone oil. Preparations that specialize in moisturizing effect moisturize the skin, but excessive moisturizing feeling often leads to stickiness and sliminess.

[0004] Patent Document 3 proposes a skin cosmetic that moisturizes and smoothes the skin by combining trimethylglycine with a specific organic acid and polyethylene glycol. However, although the moisturizing effect is refreshing and hydrating, the moist emollient effect is insufficient. [Prior art documents] [Patent documents]
