Description

Cosmetic composition of formulation that freezes at refrigeration temperature

It relates to a cosmetic composition having a formulation that freezes at a refrigerated temperature.

The average body temperature of the human body is 35.5 to 36.5 °C, and the normal range is 31 °C, which is 5 to 6 °C lower than the skin surrounding the human body. However, when exposed to an environment with a lot of sunlight for a long time, a phenomenon occurs in which the skin goes out of the average temperature range and rises to 40° C. or more. In this case, as the skin capillaries expand and the pores expand, elasticity decreases.

Recently, the relationship between skin temperature and skin aging has been studied, such as that UV rays and high skin temperature increase collagen-degrading enzymes in the dermis layer or induce rough skin texture. Interest in cosmetics is growing.

In order to effectively lower the skin temperature, a method of using a mask pack that has a soothing effect on the skin has been used. There is a problem in that it only feels cool when it is not applied, and it cannot substantially lower the temperature of the skin, and when using it frozen, it is too hard to use.

Accordingly, a composition in which xylitol and erythritol, which cause an endothermic reaction when dissolved in water, are added to the mask pack composition has been developed. Registered Patent No. 0691093 (registered on February 27, 2007), Registered Patent No. 1351858 (registered on January 9, 2014) containing urea, methyl salicylate, menthol and camphor A mask pack with a cooling agent added is presented. The above ingredients can feel a temporary refreshing feeling when applied, but the cooling sensation due to the endothermic reaction is easily connected to the stimulation of the skin, and there is a problem in that pain due to the cooling sensation may appear.

Therefore, in order to overcome the problems of the prior art, the present inventors complete a formulation that is frozen in refrigeration conditions when in use while maintaining a liquid state during movement, can sufficiently absorb a sense of heat even in refrigerated conditions, and effectively without components causing an endothermic reaction A cosmetic composition for lowering the skin temperature was prepared.
