Description

Cosmetic composition for cooling agent comprising erythritol and disiloxane}

The present invention relates to a cosmetic composition having a cooling effect, and more specifically, by including erythritol and disiloxane in a combination, it is possible to impart a feeling of cooling when applied to the skin, and it is safe to the skin because there is no skin irritation, and the feeling of use such as application is improved. It relates to a cosmetic composition for an excellent cooling agent.

The normal temperature of the skin is about 31 degrees, but if it is exposed to the sun in summer for 15 minutes, it can rise to 40 degrees, causing problems such as moisture loss and skin heat aging. In this case, cooling cosmetics that control the skin temperature are very helpful. Cooling cosmetics are products with the principle of constricting blood vessels and pores by instantly lowering the temperature of the skin surface. These products can be classified according to the ingredients that give the cooling effect. There are spray products applied with the principle of cooling sensation by reducing skin temperature by the heat of vaporization, or products that take the heat of the skin and instantly cool down when alcohol evaporates on the skin because it contains alcohol. In addition, there are products that utilize the refreshing properties of certain ingredients such as peppermint, xylitol, and menthol.

Among the cosmetics that give a feeling of cooling as mentioned above, there is a problem in that a gas-filled spray-type product must be applied at a certain distance to reduce skin irritation. In addition, since the products to which the above-mentioned ingredients are added have a problem that they cause skin irritation such as burning sensation to people with sensitive skin, there is a need for a technology to make a hypoallergenic cooling product that can be used by people with sensitive skin.

In addition, sugar alcohols such as erythritol, xylitol, sorbitol, mannitol, maltitol, etc., which have been used as alternative sweeteners, are being developed as a cooling sensation agent to give a refreshing feeling by using an endothermic reaction in an aqueous solution.

Accordingly, the present inventors have made intensive research efforts to overcome the problems of the prior art. As a result of using a combination of erythritol, which is a natural sugar alcohol component, and disiloxane, which is volatile among silicone oils, synergistically, when using as a cooling agent, it is possible to impart cooling to the skin synergistically. In addition, it was confirmed that there is no skin irritation, so it is safe for the skin and has excellent feeling of use such as application properties, and the present invention has been completed.
