[0009] According to the present application, a composition for moisturizing and protecting the skin is provided, wherein the keratin conditioner is one or more of phenyl salicylate, and the antioxidant is one or more of vitamin E, the phenyl salicylate as a keratin conditioner can help remove aged cells in the stratum corneum, promote skin renewal, and improve skin texture, and the vitamin E as an antioxidant can help resist free radical damage, protect the skin from oxidative damage, and help maintain the youth and health of the skin.

[0010] A method for preparing a composition for moisturizing and protecting the skin, comprising the following steps:

[0011] S1, add the formula amount of carbomer and PE-40 hydrogenated castor oil into the oil phase pot, heat to 70-80℃, and stir to dissolve uniformly.

[0012] S2, add the formula amount of water, glycerol and aloe vera barbadensis miller into the water phase pot, and stir to dissolve uniformly.

[0013] S3, slowly add the carbomer and PE-40 hydrogenated castor oil after heating and dissolving into the water, glycerol and aloe vera, and continue to stir until the two phases are fully mixed.

[0014] S4, adjust the pH of the product to the desired range using triethanolamine.

[0015] S5, gradually add methylparaben, dimethylglycolimadazolidinyl urea, phenoxyethanol, ethylhexylglycerin, butylmethoxydibenzoylmethane, nano zinc oxide, nano titanium dioxide, chlorpheniramine maleate and phenyl salicylate, and ensure that they are uniformly dispersed in the product.

[0016] S6, after the product temperature decreases, add vitamin E and ensure that it is uniformly dispersed in the product.

[0017] According to the preparation method of the composition for moisturizing and protecting the skin provided by the present application, the temperature needs to be heated to 70-80℃ in S1 and S2, and the pH value needs to be adjusted to 5.5-6.5 in S4. Heating to 70-80℃ can help the oil phase and water phase ingredients to be fully dissolved, ensuring that they can be uniformly mixed together. The pH value in the range of 5.5-6.5 is closer to the pH value of human skin, so it is more friendly to the skin, which helps to reduce irritation and discomfort. Adjusting the pH value of the product to the appropriate range also helps to protect the stability of the product and prevent degradation or deterioration of the ingredients due to deviation of the pH value.

[0018] According to the preparation method of the composition for moisturizing and protecting the skin provided by the present application, the product temperature needs to be reduced to below 40℃ before adding vitamin E in S6. High temperature can affect the stability of vitamin E, so reducing the product temperature to below 40℃ before adding vitamin E can reduce the influence of heat and help to maintain its activity and efficacy.

[0019] Compared with the prior art, the refreshing moisturizing composition and skin care product provided by the present application has the following beneficial effects:

[0020] I. The composition can be quickly absorbed on the skin, making the skin feel moisturized quickly, and can provide long-term moisturizing effect, so that the skin can maintain moisture for a long time.
