2,4 - dihydroxybenzophenone, with the CAS number 131 - 56 - 6, is a well - known organic compound. Its molecular formula is C₁₃H₁₀O₃, and it has a molecular weight of approximately 214.22 g/mol. This product is presented as a white to slightly yellow crystalline powder. It has a melting point in the range of 132 - 138 °C. The compound is soluble in ethanol, ether, and acetone, but sparingly soluble in water.
In terms of quality, our High Quality 2,4 - dihydroxybenzophenone meets strict industry standards. We ensure its purity through advanced production and refining processes, providing customers with a reliable and consistent product.
2,4 - dihydroxybenzophenone is widely used in various industries. In the cosmetic industry, it serves as a UV absorber. It can protect the skin from the harmful effects of ultraviolet rays by absorbing UV - B radiation. This helps prevent sunburn, premature aging of the skin, and reduces the risk of skin cancer. It is commonly added to sunscreens, lotions, and other skincare products.
In the plastics industry, it is used as a light stabilizer. Plastics are prone to degradation when exposed to sunlight, which can lead to changes in color, mechanical properties, and transparency. By adding 2,4 - dihydroxybenzophenone, the plastic products can have an extended service life and maintain their original performance under sunlight exposure.
It also finds applications in the printing ink industry. The compound can improve the lightfastness of inks, ensuring that printed materials retain their color and clarity for a longer time, especially when used outdoors or in areas with high light exposure.
When using 2,4 - dihydroxybenzophenone in cosmetics, it should be added at an appropriate concentration. Usually, the recommended dosage in sunscreens is around 2% - 5% by weight. First, it needs to be dissolved in a suitable solvent such as ethanol or a mixture of solvents, and then added to the cosmetic formulation during the production process with thorough stirring to ensure uniform dispersion.
In the plastics industry, the amount of 2,4 - dihydroxybenzophenone added depends on the type of plastic and the specific application requirements. Generally, it is added at a dosage of 0.1% - 1% during the plastic processing stage. It can be mixed with the plastic resin before melting and extrusion to ensure it is evenly distributed in the plastic matrix.
For the printing ink industry, it can be added directly to the ink formulation. The addition amount is typically 0.5% - 2% and should be well - mixed with other ink components to achieve the best light - stabilizing effect.
Case 1: Cosmetic Company
A well - known cosmetic company was facing the problem of sunscreens not providing sufficient UV protection and having inconsistent quality. They started using our high - quality 2,4 - dihydroxybenzophenone. After adding it to their sunscreen formula at a concentration of 3%, they conducted extensive UV protection tests. The results showed that the sun protection factor (SPF) of their sunscreen increased significantly, and the product passed strict quality control tests. Customer feedback also indicated that the new sunscreen provided better protection and was more effective in preventing sunburn.
Case 2: Plastic Product Manufacturer
A plastic product manufacturer producing outdoor furniture was experiencing issues with their products fading and becoming brittle after long - term sunlight exposure. They introduced 2,4 - dihydroxybenzophenone into their plastic resin at a dosage of 0.5%. After outdoor exposure tests for several months, the plastic furniture showed much less color change and maintained its mechanical strength. This led to an increase in customer satisfaction and a reduction in product returns due to quality problems.
Case 3: Printing Company
A printing company was printing large - scale outdoor billboards. The inks they used were fading quickly under sunlight, which affected the visual effect and advertising value of the billboards. By adding 2,4 - dihydroxybenzophenone at 1% to their ink formulation, the printed billboards retained their vivid colors for a much longer time. This not only improved the quality of their printing but also enhanced their reputation in the market.
