High Purity Stearoyl Benzoyl Methane Sbm 58446-52-9 Stearic Acid Benzylidene Phenyl Ester

Stearoyl Benzoyl Methane (SBM) is an organic compound that is commonly used in the cosmetics and personal care industry as an ultraviolet (UV) absorber. It is also known by its chemical name, 4-tert-Butyl-4'-methoxydibenzoylmethane, and is often used in combination with other UV filters to provide broad-spectrum protection against both UVA and UVB rays.

SBM works by absorbing UV radiation and converting it into heat, which is then dissipated harmlessly. This helps to protect the skin from the damaging effects of UV radiation, which can include premature aging, sunburn, and an increased risk of skin cancer.

PART  B: Medicine  Functions
In addition to its use in sunscreens and other UV protection products, SBM is also used as a fragrance ingredient, as well as a plasticizer in some applications. It is considered to be safe for use in cosmetics and personal care products by regulatory agencies such as the U.S. Food and Drug Administration (FDA) and the European Union (EU).
