2,8-dihydroxy-1-methoxy-3-methylanthracene-9,10-dione - Introduction
obtusifolin, also known as White Cassia, is a natural chemical whose chemical structure is mainly composed of homo-tyrosine. It is a white crystalline powder, tasteless and odorless, soluble in water and ethanol.
obtusifolin is often used in whitening skin care products, with obvious whitening effect. It can inhibit the production of melanin, reduce pigmentation, improve uneven skin tone. In addition, obtusifolin also has antioxidant properties, can scavenge free radicals, slow down the aging process of the skin.
There are two main methods for preparing obtusifolin. One is to extract the desired compounds from natural materials through chemical synthesis. The other is through fermentation, the use of specific microbial synthesis products.
Although obtusifolin is widely used in beauty and skin care and is considered a relatively safe chemical substance, it is still necessary to pay attention to the safety of its use. Before using obtusifolin, it is recommended to conduct an allergy test to exclude the risk of allergic reactions. In addition, avoid prolonged exposure to the sun to avoid causing photosensitive reactions. If you find symptoms, you should stop using it in time and consult a professional.
