What is the Difference Between Benzophenone-3 and Benzophenone-4?

Benzophenone-3 and Benzophenone-4 are derivatives of benzophenone, which are used in sunscreen products and personal care products. The main differences between Benzophenone-3 and Benzophenone-4 are:

• Concentration in Sunscreen Products: In the United States, Benzophenone-3 (also called Oxybenzone) can be used at a concentration of up to 6%, while Benzophenone-4 (also called Sulisobenzone) can be used at a concentration of up to 10%.
• Chemical Formula: Benzophenone-3 has the chemical formula C14H12O3, while Benzophenone-4 has the chemical formula C14H12O6S.

Both Benzophenone-3 and Benzophenone-4 are used in sunscreen products to protect the skin from UV rays. They are also used in personal care products, such as nail polishes, enamels, bath products, makeup products, hair products, and skincare products. When used in cosmetics and personal care products, Benzophenones are not considered irritating or sensitizing. They are also nonmutagenic and nonphototoxic.

Comparative Table: Benzophenone-3 vs Benzophenone-4

Benzophenone-3 and Benzophenone-4 are derivatives of benzophenone, which are commonly used in sunscreen products. The main differences between these two compounds are their chemical formulas, concentrations in sunscreen products, and potential toxicological effects. Here is a comparison table of Benzophenone-3 and Benzophenone-4:

Benzophenone-3, also known as oxybenzone, is an organic compound with the chemical formula C14H12O3. In sunscreen products, it can be used at a concentration of 6% or below. Benzophenone-4 is an organic compound with the chemical formula C14H12O6S, and it can be used in sunscreen products at a concentration of 10% or below.

Both benzophenone-3 and benzophenone-4 are used in sunscreen products to protect the skin from the sun's UV radiation. However, there are some concerns about their potential toxicity and impact on the environment. Further research is needed to fully understand the long-term effects of these compounds on human health and the environment.
