Problems solved by technology

Most of the above-mentioned sunscreens are packaged in plastic or glass bottles and are in the form of milk or cream. They need to be applied manually, and they are relatively sticky and greasy, which makes them inconvenient to use. This problem is particularly prominent during travel.
At the same time, thick and oily sunscreen products have a large amount of residue, which will bring a great burden to the skin
[0003] In addition, free radicals (also known as active oxygen) are the culprits of the aging of the human body and the occurrence of many diseases, and the existing sunscreen products have not eliminated the harmful components of free radicals in human skin

Embodiment 1

[0017] Homosalate, benzophenone-3, polysiloxane-15, octyl methoxycinnamate, octyl salicylate, octocrylene, vitamin E, vitamin C, acrylates / octyl The base acrylamide copolymer was dissolved in absolute alcohol, stirred evenly, and allowed to stand for one hour. After standing still, check whether the obtained sunscreen solution meets the national standard for skin care products, and if it is qualified, it can be filled in an aerosol can.

[0018] Wherein, the described homosalate, benzophenone-3, polysiloxane-15, octyl methoxycinnamate, octyl salicylate, octocrylene, acrylic acid (ester) / octyl propylene, Vitamin E, vitamin C and absolute alcohol are respectively 9.50, 9.10, 7.50, 6.20, 4.00, 3.50, 3.00, 0.40, 0.20, 56.60 in percentage by weight of the total solution. The sunscreen solution configured in the above weight ratio achieves a relatively ideal cost-effective ratio in terms of materials and efficacy.

[0019] The acrylic acid (ester) / octylacrylamide copolymer has the...

Embodiment 2

[0021] The skin irradiation experiment was done with rabbits to identify the sunscreen effect of the sunscreen solution of Example 1. Take healthy rabbits and set up an experimental group and a control group. The experimental group applies sunscreen and skin care products on the shaved area, and the control group applies ordinary moisturizer. They irradiate discontinuously under ultraviolet light for a total of 10 times, 10 minutes each time, twice a day. times, observed after 5 days. The results showed that the exposed skin of the control group had allergic reactions, blisters and shedding, while the skin of the rabbits coated with sunscreen and skin care products was normal. Biological activity identification proves that the sunscreen solution of Example 1 can play a good role in sun protection.

Embodiment 3

[0023] 20 healthy guinea pigs of 250-300 g were selected, and their hair was sheared within 3×3 cm on both sides of the neck, back and spine. The sunscreen solution in Example 1 was used as the test substance, and the dosage was 0.1 mL. Sensitization test, sensitization 3 times, once a week, after the last sensitization interval of 2 weeks, the challenge contact test was carried out, the results showed that the tested guinea pig skin did not appear allergic reaction.
