Benzophenones prevent UV light from damaging scents and colors in products such as perfumes and soaps. It can also be added to the plastic packaging as a UV blocker. Its use allows manufacturers to package the product in clear glass or plastic.
Oxybenzone aka benzophenone-3
Oxybenzone provides broad-spectrum ultraviolet coverage, including UVB and short-wave UVA rays.
Oxybenzone is used in plastics as an ultraviolet light absorber and stabilizer. It is used, along with other benzophenones, in sunscreens, hair sprays, and cosmetics because they help prevent potential damage from sunlight exposure. It is also found, in concentrations up to 1%, in nail polishes. Oxybenzone can also be used as a photostabilizer for synthetic resins.
Regulations on Oxybenzone by country
Sweden has banned benzophenone-3 in sunscreens.
|Range: UVB, UVA2||Max: 3%||Absorbs UVB rays and short-wave UVA rays||Derivative of benzophenone; Insoluble in water; FDA approved|
|Range: UVB, UVA2||Max: 5%||Absorbs UV rays||Photostable; Helps stabilize other UV filters; Absorbed by skin so its safety use in sunscreen is questionable. More information is needed; FDA approved. Offers improved stability of formula fragrance and color.|
Used as fixatives for heavy perfumes (e.g., geranium) and soaps (the smell of “new-mown hay”). Obtained as a white, flaky solid with a delicate, persistent, roselike odor, and soluble in most fixed oils and in mineral oil. Also used in the manufacture of hair sprays and in sunscreens. They help prevent deterioration of ingredients that might be affected by the ultraviolet rays found in ordinary daylight. May produce hives and contact sensitivity. In sunscreens they may cause immediate hives as well as other photoallergic reactions. Also may cause face and neck rashes when in shampoo. On the basis of the available information, the CIR Expert Panel found it safe in the early 1980s but is considering new information to determine if the final safety assessment should be reaffirmed, amended, or have an addendum.
Used in cosmetics like gels and shampoos, colorant, setting lotions, normal and gloss hair sprays. Acts as a UV filter. Offers benefits such as colour protection and improved stability.« Back to Dictionary Home
