The difference between zinc oxide, cinnamic acid and biological sunscreen
According to the composition of sunscreen, sunscreen is divided into three categories: physical sunscreen, chemical sunscreen and biological sunscreen. The following is an introduction to the principles of these three sunscreens, so that you can better understand the differences between them.
Sun protection is achieved by shielding ultraviolet rays through light reflection. The main ingredients are titanium dioxide and zinc oxide, which have a certain concealer effect. When applied to the skin, there will be an illusion of foundation make-up. Zinc oxide is one of the most widely used physical sunscreen agents, which can block the radiation of UVA and UVB bands, and is safe and non-irritating. Zinc oxide is a white hexagonal crystal, insoluble in water and soluble in acidic substances, with high safety, but it will become white and sticky when applied to the skin.
By absorbing ultraviolet rays, it can be converted into heat and then released to achieve sunscreen effect. The main ingredients are p-aminobenzoic acid, cinnamic acid and benzophenone, which are mostly colorless for skin. Here, for example, cinnamic acid can be added to sunscreen, which has the effect of inhibiting the formation of black tyrosinase, has a certain insulating effect on ultraviolet rays, and can make brown spots light, even disappear. It is one of the essential ingredients in advanced sunscreen. The significant antioxidant effect of cinnamic acid has a good effect on reducing the appearance of wrinkles.
Biological sunscreen mainly includes vitamin C, vitamin E, nicotinamide β- Carotene and plant extracts can reduce oxidizing substances and effectively eliminate free radicals, and inhibit melanin synthesis. So as to block or slow down the tissue damage or promote the repair after sunburn, and play the role of indirect sunscreen.
The three kinds of sunscreen products have their own advantages and disadvantages. Physical sunscreen products have less damage to the skin, but they are thick, easy to block pores, and are not suitable for acne; Chemical sunscreen is relatively refreshing, but the added chemical component muscle matrix is easy to stimulate the skin and is not suitable for sensitive muscles; Plant sunscreen has both advantages and can be selected as appropriate.
Recently, the invention patents "a reaction kettle for the oxidation of cinnamaldehyde to prepare cinnamic acid" and "a potassium cinnamate drying device" applied by the company won the patent rights granted by the State Intellectual Property Office, and both obtained the Utility Model Patent Certificate. As an enterprise specializing in the production of cinnamon series products, we adhere to the management concept of "quality first, reputation first, management first, and service first", and pay special attention to the innovation of production technology while ensuring the production of high-quality products. Yu Chunping, General Manager, and Xu Qinfeng, Deputy General Manager, combined with the actual situation of the company's production line, collected the opinions of technical workers, studied, verified and tested in various ways, and devoted themselves to the patent research and development work, and finally achieved gratifying results.
