What is Oxybenzone?
Oxybenzone is an organic compound used in sunscreens. It is a derivative of benzophenone. It forms colorless crystals that are easily soluble in most organic solvents. It is used as an ingredient in sunscreens and other cosmetics because it absorbs UV-A rays.
Oxybenzophenone absorbs UVB and UVA II rays, leading to photochemical excitation and energy absorption. After returning to the ground state, the absorbed energy will cause the emission of longer wavelength radiation and reduce the penetration of radiation to the skin, thus reducing the risk of DNA damage.
Benzophenone-3 is an organic sunscreen (from carbon). This sunscreen primarily absorbs UVB and shorter wavelength UVA radiation, which are associated with tanning, sunburn and skin cancer.
In the ingredient list on the package, it’s named “OXYBENZONE” in the US and Canada and “OXYBENZONE-3” in the rest of the world.
Benzophenone-3 is a synthetic organic compound (based on carbon, oxygen, and hydrogen) that absorbs ultraviolet light.
- Benzophenone-3 is stable in light, so it can work when exposed to sunlight.
- Benzophenone-3 protects the skin from sun damage. It mainly absorbs UVB radiation, which can cause sunburn and also increase the risk of skin cancer. It also absorbs shorter-wavelength UVA that can cause skin aging.
- Benzophenones are additionally extensively used in various home and consumer products. Benzophenones can be added to laundry and cleansing item solutions as scent substances and additionally aid shield items from destruction triggered by UV rays and also direct exposure to air.
- In skin care items such as soaps as well as lip balms, benzophenone assists safeguard product shade and also scent by stopping various other product ingredients from breaking down under UV light. Benzophenone-3, a by-product of benzophenone, is also a crucial component in several sunscreens as a result of its ability to take in damaging UV rays.
- In consumer products such as sunglasses, shoes and also sports equipment, benzophenone aids shield versus UV damage or damage to products. Additionally, as a component in non-plastic packaging, it aids protect against light damages as well as fading of the item inside the packaging.
