Description

Transparent stick type cosmetic composition for UV protection {A TRANSPARENT STICK-TYPE UV-SUNSCREEN COSMETIC COMPOSITION}

The present invention relates to a sunscreen cosmetic composition of the transparent stick formulation.

Formulations used in sunscreen cosmetics include liquid, cream, cake, solid, spray and stick. Among these, liquid or creamy sunscreens are inconvenient to be rubbed onto the palms or fingers. In addition, the cake or solid sunscreen has a disadvantage of causing skin troubles by increasing the contamination of the sponge itself because the sponge is repeatedly used without a disposable sponge (puff). Spray-type sunscreens are difficult to apply to the face is limited in use, there is a lot of cosmetic waste disadvantages.

Stick-type sunscreen is expected to be able to solve some of the inconvenience, but the stick-type sunscreen currently on the market is exposed to the problem that the ease of use is not applied smoothly. This problem appears to be due to the wax component of the animal, vegetable and / or mineral ester series in which the cosmetic form in the form of sticks is added to have a certain strength. In addition, commercially available stick-type sunscreens include inorganic UV-blockers in the form of fine particles such as titanium dioxide and zinc oxide as sunscreens, and these fine particles also increase the viscosity of the stick-type cosmetics to cause a stiff feeling of use.

On the other hand, the inorganic UV blocker, in addition to the above problems in the stick-type sunscreen, generally causes a white or bluish white phenomenon when not spread well when used, and fine particles such as titanium dioxide, zinc oxide between the skin texture It is known to cause the problem of being deposited and not easily falling off during cleaning. However, when the inorganic UV blocker is used together with the organic UV blocker, the UV block index can be easily increased. However, when the UV blocker is manufactured using only the organic UV blocker, it is not easy to secure a high UV block index. For this reason, most sunscreens on the market appear to contain inorganic sunscreens.

Therefore, for the manufacture of stick-type sunscreens with minimal use inconvenience, the application of waxes of animal, vegetable and / or mineral ester-based waxes replaces existing animal-based, vegetable-based and mineral ester-based waxes, while providing a strength sufficient to maintain a stick-type formulation. The development of a raw material having a high molecular weight and an ultraviolet ray blocking agent alone is required to develop a technology capable of securing a high UV blocking index.

The present invention provides a soft feeling by using a raw material having a soft applicability while providing a strength enough to maintain the stick-shaped formulation by replacing the wax component of the animal, vegetable and / or mineral ester series of the existing;

Solve the problems of clouding, stiff feeling, and poor cleanliness caused by using inorganic UV blocker by using only organic UV blocker as a sunscreen, and have high UV protection index, and it is transparent and provides visual refreshing feeling. An object of the present invention is to provide a transparent stick-type sunscreen cosmetic composition having excellent quality.
