Usage

General Description

4,4'-Dihydroxy-3,3'-dimethyldiphenylmethane is a chemical compound that belongs to the group of benzophenones. It is commonly used in the cosmetics and personal care industry as a UV filter to protect the skin and hair from the damaging effects of the sun's ultraviolet rays. 4,4'-DIHYDROXY-3,3'-DIMETHYLDIPHENYLMETHANE is also known for its antioxidant properties, which help to prevent the formation of free radicals that can cause skin aging and damage. Additionally, it is used in the manufacturing of plastics, adhesives, and other industrial products. However, there are concerns about its potential endocrine-disrupting effects and its impact on the environment, leading to restrictions on its use in some regions.

METHOD OF PRODUCING POLY(ORTHO-METHYLPHENOL)

Poly(ortho-methylphenol) is obtainable at high purities and yields using industrial processes by causing a secondary amine and formaldehyde to react with a polyphenol (first step), and then breaking down the aminomethyl group of the obtained poly(ortho-aminomethyl)phenol by means of hydrogenolysis in the presence of a hydrogenation catalyst (second step).
