The cosmetics using refreshing feel, have such usability fairly spreadable, present refeshing feel, have such usability as not to be sticky, and are less apt to be washed away by sweat or water.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention is characterized by containing a silicone cinnamic acid derivative which is soluble in silicone oil, has excellent water resistance and oil resistance, and has an ultraviolet absorbing property in the wavelength range of UV-B. The present invention relates to a novel sunscreen cosmetic having a sunscreen effect, excellent usability, and an effect of enhancing makeup retention.

[0002]

BACKGROUND OF THE INVENTION Ultraviolet light is known to cause various changes in the skin. When dermatologically classifying ultraviolet rays, they are divided into 400-320 nm long-wave ultraviolet rays called UV-A, 320-290 nm UV-B intermediate wavelength ultraviolet rays, and 290 nm or less UV-C short-wave ultraviolet rays. . Usually, most of the ultraviolet rays that humans are exposed to are sunlight, but the ultraviolet rays that reach the ground are UV-
In A and UV-B, UV-C is absorbed in the ozone layer and hardly reaches the ground. Among the ultraviolet rays that reach the ground, UV-B causes changes such as erythema and blisters when the skin is irradiated with a certain amount of light or more, and melanin formation is accelerated and pigmentation occurs. .

Therefore, protecting the skin from UV-B is extremely important in the sense of preventing the acceleration of aging of the skin and preventing the generation and exacerbation of spots, freckles, and various UV-B absorptions. Has been developed.

With respect to Examples 1 to 6 and Comparative Examples 1 to 6 obtained as described above, the ultraviolet protection effect was measured. The UV protection effect was measured using the UV sensitive composition shown below. The measurement of the effect of preventing ultraviolet rays is made in Japanese Patent Laid-Open No.
It carried out using the ultraviolet-sensitive composition as described in JP-A-2-112020. The method for producing the ultraviolet-sensitive composition will be described below. A solution composed of 1.0 g of leuco crystal violet, 0.1 g of tetrabromodimethyl sulfone, 10 g of ethylene-vinyl acetate copolymer and 100 ml of toluene was prepared and designated as solution I. Separately from this, a liquid consisting of 7 g of N, N-dimethylparaaminobenzoic acid-2-ethylhexyl ester, 10 g of ethylene-vinyl acetate copolymer, and 100 ml of toluene was prepared to be a liquid II. First, the solution I was coated on the photographic base paper at a solid content of 1 g / m ² and dried, and then the solution II was coated thereon at a solid content of 5 g / m ² to give an ultraviolet-sensitive composition. obtain.

This UV-sensitive composition is a paper that changes its color from white to light purple to purple to purple to dark purple by increasing the irradiation dose of ultraviolet light by irradiating with ultraviolet light. 40 mg of the sample to be measured is mixed with 12 g of castor oil, and roller-treated to uniformly disperse. A transparent PET film was placed on the circular UV-sensitive composition having a diameter of 5 cm, 1.5 g of the transparent PET film was applied on the composition so as to have a uniform thickness, and an ultraviolet lamp was irradiated for 8 minutes to apply the PET film to each sample. The removed and colored UV-sensitive composition was subjected to a color difference calculation in a LAB coordinate system using a Hitachi 607 spectrophotometer with reference to the color of the UV-sensitive composition when the UV irradiation dose was zero. The results are shown in Table 1.
