[0049] The present invention also provides a preparation method of the sunscreen according to the present invention, comprising: a step of mixing the components of the sunscreen.

[0050] According to the method of the present invention, comprise the following steps:

[0051] 1) Grinding after mixing the physical sunscreen and liquid oil to obtain a powder;

[0052] 2) Add the ground powder, oil phase thickener, emulsifier, antioxidant, chemical sunscreen, oil-soluble preservative into the emulsification pot, stir and heat to 80-85°C to dissolve;

[0053] 3) Add deionized water, humectant, complexing agent, crosslinking agent, and inorganic salt into the water phase stirring pot, stir and heat to 80-85°C and dissolve completely to obtain the water phase substance;

[0054] 4) Pump the water phase material into the emulsification pot, stir and heat to 80°C, and then cool down after homogeneous stirring.

[0055] 5) Cool down to 42-45°C, add antisensitizers, polypeptides, flav...

Embodiment 1-3

[0060] According to the content (number of parts) of each component of the sunscreen of Example 1-3 in the following table 2, and according to the steps of the following preparation method, sunscreen I-III is prepared, and the ultraviolet absorbance of sunscreen I-III is measured and infrared absorbance.

[0061] The preparation method is:

Abstract

The invention provides sunscreen cream and a preparation method thereof. In terms of the total weight of the sunscreen cream, the sunscreen cream comprises components as follows: 2%-10% of a physical sunscreen agent, 2%-30% of a chemical sunscreen agent, 0.01%-1% of an antioxidant, 5.5%-20% of grease, 2%-6% of an emulsifier, 3%-15% of a humectant, 0.1%-2% of polypeptide and 10%-85% of water, preferably, 5%-10% of the physical sunscreen agent, 15%-25% of the chemical sunscreen agent, 0.1%-0.8% of the antioxidant, 10%-20% of the grease, 4%-6% of the emulsifier, 8%-15% of the humectant, 0.1%-1.5% of the polypeptide and 22%-53% of the water. The sunscreen cream not only has ultraviolet protection function, but also can protect human tissue from getting infrared ray harm.

Description

technical field [0001] The invention relates to a sunscreen and a preparation method thereof, belonging to the field of daily chemicals. Background technique [0002] The damage of ultraviolet rays to human skin has been increasingly recognized by people. At present, there are many kinds of sunscreen products on the market, including sunscreen, sunscreen lotion, sunscreen spray, etc. At the same time, there are all kinds of products with high, medium and low SPF. All sunscreen products are mainly based on UV protection, and their protection range is mainly It is a band for protecting UVB (medium-wave dark spot effect ultraviolet rays) and UVA (long-wave dark spot effect ultraviolet rays). People have not paid enough attention to the damaging effects of infrared rays, another wavelength of sunlight, on the skin. [0003] Infrared rays can be divided into two categories: near infrared rays and far infrared rays. Near-infrared rays are also called short-wave infrared rays, w...
