Problems solved by technology

Studies have shown that the most commonly used inorganic sunscreens (nano-titanium dioxide and nano-zinc oxide, etc.) have the characteristics of small particle size, large specific surface area, strong adsorption capacity, and insoluble in water. They are easy to aggregate and deposit, showing oxidative damage. , physical damage, ion release and other toxic mechanisms; organic sunscreens (BP-3, 4-MBC, EHMC, etc.) have the characteristics of strong fat solubility and easy bioaccumulation, showing oxidative damage, endocrine disruption, neurotoxicity and bioaccumulation, etc. Negative effects, both types of sunscreens have significant toxic effects on a variety of marine organisms (bacteria, fish, algae, shellfish, corals, etc.), causing damage to the entire marine ecosystem
[0005] In the prior art, there are few researches on environmentally friendly sunscreen products that do not use inorganic sunscreens and organic sunscreens, and there are not many environmentally friendly sunscreen products available on the market

Abstract

The invention belongs to the technical field of sunscreen cream, and discloses a sunscreen cream and a preparation method thereof. Wherein, the sunscreen cream provided by the invention comprises thefollowing components in parts by mass: 0.5 to 5 parts of tea polyphenol, 1 to 6 parts of barbaloin, 0.5 to 8 parts of apple polyphenol, 2 to 10 parts of mycosporine-like amino acids, 0.5 to 8 parts ofchitosan, 2 to 8 parts of emulsifier, 10 to 45 parts of grease, 0.5 to 6 parts of humectant, 1 to 5 parts of film-forming agent, 0.1 to 2 parts of aromatic plant essential oil, 0.2 to 1 part of antioxidant, 0.1 to 1 part of pH regulator, 0.1 to 3 parts of other additives, and 10 to 60 parts of water. According to the sunscreen cream disclosed by the invention, a natural sunscreen agent is adopted, and no organic sunscreen agent and an inorganic sunscreen agent are used, so that the sunscreen cream is friendly to the marine environment without pollution, and has a good protection effect on ultraviolet rays, the sunscreen effect is durable and stable, and has certain skin care effects of moisturizing and oxidation.

Description

technical field [0001] The invention relates to the technical field of sunscreen, in particular to a sunscreen and a preparation method thereof. Background technique [0002] With the rapid development of industrialization, the environment is also affecting human beings, such as the destruction of the ozone layer, resulting in the gradual increase of ultraviolet rays reaching the earth's surface. Excessive ultraviolet radiation is detrimental to human health. Long-term exposure to ultraviolet light can cause skin sunburn in mild cases, and erythema, sunburn, and skin cancer may occur in severe cases. With increasing awareness of the dangers of UV rays, sunscreen products have become an everyday item in personal care. [0003] During the use and production of sunscreen products, the sunscreen agents used in sunscreen products inevitably enter coastal waters through various channels (such as sewage treatment plant discharge, runoff input, and water entertainment activities, e...
