As the harmful effects of UV radiation on human skin become more widely known, the demand for UV-absorbing products has increased significantly. The UV absorber BP-2, also known as UVBP-2, Light Stabilizer BP-2, 2,2,4,4-Tetrehydroxybenzophenone, Di(2,4-dihydroxyphenyl)methanone, Bis(2,4-dihydroxyphenyl)methanone, or Benzophenone-2, has become a popular ingredient in personal care products, coatings, and plastics. Ningbo Inno Pharmchem Co., Ltd., a leading factory and supplier of specialty chemicals, has recently conducted a feasibility analysis of 2,2,4,4-Tetrehydroxybenzophenone and found that it is a promising UV absorber for various applications.

UVBP-2 is a white crystalline powder that is soluble in most organic solvents and has a melting point of 151-154°C. It is a derivative of benzophenone, a well-known UV absorber that has been widely used in the industry for decades. However, BP-2 has several advantages over its predecessor. Firstly, it has a higher molar extinction coefficient in the UVB range (280-320 nm) than benzophenone, which means that it absorbs more UV radiation per unit of concentration. Secondly, it has a lower melting point and is more soluble in water than benzophenone, which makes it easier to incorporate into aqueous formulations. Finally, it has a lower toxicity and is less likely to cause skin irritation than benzophenone.

The primary application of UVBP-2 is in personal care products, such as sunscreens, moisturizers, and hair care products. It is used to protect the skin and hair from UV radiation, which can cause sunburn, premature aging, and skin cancer. UVBP-2 is effective in absorbing both UVA (320-400 nm) and UVB radiation, which are the two types of UV radiation that penetrate the earth's atmosphere. It is also photo-stable, which means that it does not break down or lose its effectiveness when exposed to sunlight. This makes it an ideal ingredient for products that are intended to be used outdoors.

In addition to personal care products, UVBP-2 is also used in coatings and plastics to improve their UV resistance. Coatings and plastics that are exposed to sunlight can become discolored, brittle, and crack, which can decrease their lifespan and durability. UVBP-2 helps to prevent this by absorbing the UV radiation that causes the degradation of the material. It can be used in a variety of coatings and plastics, such as automotive coatings, wood coatings, and PVC plastics.

Ningbo Inno Pharmchem Co., Ltd. has conducted extensive research on the production and application of UVBP-2. They have found that it is a stable and reliable UV absorber that can be easily incorporated into various formulations. They have also developed a scalable production process that can produce high-quality UVBP-2 at a reasonable cost. Their production facilities are equipped with state-of-the-art equipment and staffed by experienced technicians, ensuring that their products meet the highest standards of quality and purity.

In conclusion, 2,2,4,4-Tetrehydroxybenzophenone, also known as UVBP-2, is a promising UV absorber that has many applications in the personal care, coatings, and plastics industries. Its high molar extinction coefficient, low toxicity, and photo-stability make it an attractive alternative to benzophenone and other UV absorbers. Ningbo Inno Pharmchem Co., Ltd., as a reputable manufacturer and supplier of specialty chemicals, is well-positioned to meet the growing demand for UVBP-2. Their extensive research and production capabilities ensure that their products are of the highest quality and can be tailored to meet the specific needs of their customers.
