The product we are discussing is Factory Supply 2,2′,4,4′-tetrahydroxybenzophenone, with the CAS number 131 - 55 - 5. It is supplied at a good price, which makes it an attractive option in the market. The chemical formula of 2,2′,4,4′-tetrahydroxybenzophenone is (C_{13}H_{10}O_{5}). It is a white to off - white powder. The melting point of this compound is approximately in the range of 194 - 198°C. It has a certain solubility property; it is sparingly soluble in water but soluble in organic solvents such as ethanol, acetone, and ether. These solubility characteristics determine its application scope in different chemical and industrial processes.
2,2′,4,4′-tetrahydroxybenzophenone has a wide range of uses in various industries. In the cosmetic industry, it is a well - known UV absorber. It can effectively absorb ultraviolet rays in the UVB and UVA regions, protecting the skin from the harmful effects of sun exposure. Products such as sunscreens, lotions, and lip balms often contain this compound to provide sun protection. In the plastic industry, it acts as a light stabilizer. Plastics are prone to degradation under the influence of sunlight, which can lead to changes in their physical and mechanical properties. By adding 2,2′,4,4′-tetrahydroxybenzophenone, the plastic products can resist the damage caused by UV radiation, extending their service life. It is also used in the paint and coating industry. Coatings containing this compound can maintain their color and gloss for a longer time under sunlight, improving the durability and appearance of the painted surfaces.
When using 2,2′,4,4′-tetrahydroxybenzophenone in the cosmetic industry, it should be carefully formulated. First, it needs to be dissolved in an appropriate organic solvent according to its solubility characteristics. Then, it is added to the cosmetic base at a suitable ratio. Usually, the addition amount is determined by the required sun protection factor (SPF) of the cosmetic product. In the plastic industry, it can be added during the plastic manufacturing process. It can be mixed with plastic resins evenly before the extrusion or molding process. The dosage depends on the type of plastic and the environmental conditions where the plastic products will be used. In the paint and coating industry, it is added to the paint formulation. It should be dispersed uniformly in the coating system to ensure its effectiveness in protecting the painted surface from UV damage.
Case 1: A cosmetic company developed a new sunscreen product. By adding 2,2′,4,4′-tetrahydroxybenzophenone at a ratio of 3% in the formulation, the product achieved an SPF of 30. After conducting in - vivo tests on a group of volunteers, it was found that the sunscreen effectively protected the skin from sunburn and premature aging caused by UV radiation. Volunteers reported that their skin felt less irritated and showed fewer signs of sun damage after using the product.
Case 2: A plastic manufacturing company produced PVC pipes. They added 2,2′,4,4′-tetrahydroxybenzophenone at a dosage of 1% in the PVC resin during the extrusion process. The pipes were installed outdoors for a long - term trial. After one year, compared with the pipes without the light stabilizer, the pipes with 2,2′,4,4′-tetrahydroxybenzophenone showed no significant change in color, strength, and flexibility. In contrast, the pipes without the stabilizer became brittle and their color faded due to UV exposure.
Case 3: A paint manufacturer added 2,2′,4,4′-tetrahydroxybenzophenone to an exterior wall paint. The painted walls maintained their original color and gloss for more than two years under continuous sunlight. In comparison, the walls painted with the paint without the UV absorber started to show signs of color fading and peeling after only one year.
