LAB values of the above samples were determined using Skin-Colorimeter CL40, as follows:
the observation of the table shows that the A values of the anhydrous eye shadow and the cream are increased after a certain amount of the product is applied to the yellowish skin, and the A values represent the redness of the skin, so that the two groups of products have certain correction effect on the skin color and can enable the yellowish skin to become reddish.
The sun protection factor SPF and PA values of the control and the sun protection factor SPF and PA values of the control after 30min uv exposure were determined using the SPF-290AS sun protection factor test system manufactured by Optometrix (usa) AS follows:
as can be seen from the above table, the order of the SPF and UVA reduction rates after 30min uv irradiation is: comparative example 2 application comparative example 3 application comparative example 1 application comparative example 4 application example 2. The SPF and UUV reduction rates of the application example 2 are obviously lower than those of the comparison example 2, which shows that the stability of the composition of avobenzone and octyl methoxycinnamate is obviously enhanced after the pigment and the octyl methoxycinnamate are coated. The values of SPF and UVA reduction of application example 2 were less than those of comparative example 1, indicating that the pigments have a certain absorption of uv light, enhancing the stability of the composition.
Before ultraviolet irradiation, the SPF values are in the following order: application example 2> application comparative example 1> application comparative example 3> application comparative example 4. After 30min of ultraviolet irradiation, the decreasing sequence of SPF values is as follows: application example 2> application comparative example 1> application comparative example 2> application comparative example 4> application comparative example 3. The SPF values of application example 2 were highest both before and after uv exposure, indicating that sunscreen compositions containing octyl methoxycinnamate (containing solvent violet 13(CI60725) pigment) and avobenzone significantly increased the SPF of the cream.
Using UV-2012PC type UV-vis spectrophotometer to determine solvent violet 13(CI60725) -ethanol solution with mass fraction of 0.01% as shown in fig. 2;
measuring 0.2% octyl methoxycinnamate-ethanol solution by UV-2012PC ultraviolet-visible spectrophotometer shown in figure 3;
as can be seen from FIGS. 2 and 3, a significant absorption peak of the solvent violet 13(CI60725) pigment at 250nm is observed, which indicates that the pigment has a significant absorption effect on ultraviolet light. The octyl methoxycinnamate has no absorption peak at 250nm, which indicates that the solvent purple 13(CI60725) pigment and the octyl methoxycinnamate can play a good complementary role in absorbing ultraviolet rays.
The above description is only a basic description of the present invention, and any equivalent changes made according to the technical solution of the present invention should fall within the protection scope of the present invention.

the first step is as follows: dissolving xanthan gum in deionized water, heating in 80 deg.C water bath, stirring to dissolve completely, and adding glycerol, propylene glycol, and microparticle containing octyl methoxycinnamate to obtain phase B;
the second step is that: heating Brij72, Brij721, cetostearyl alcohol, silicone oil, isooctyl palmitate, GTCC, white oil, lanolin, and avobenzone in 80-90 deg.C water bath for melting to obtain phase A;
the third step: heating the phase A in 83-93 deg.C water bath when the phase A is the same as the phase B, and slowly adding the phase A into the phase B under the condition of stirring the phase B at 550r/min when the phase A is the same as the phase B;
the fourth step: after the phase B and the phase A are mixed, stirring the cream for 20-30min in water bath at 83-93 ℃ and at the constant temperature of 450-;
the fifth step: taking out the cream, slowly stirring at normal temperature for 50r/min until the temperature is reduced to 30-40 ℃, adding the phase C, standing and cooling to obtain the product.
