2-Phenylphenol

2-Phenylphenol (CAS 90-43-7) is a hydroxylated biphenyl compound, also known as o-Biphenylol, o-Phenylphenol, o-Xenol, and abbreviated as OPP or HBP. It is registered under EC 201-993-5 and is fully compliant with REACH regulation. No E-code designation applies to this substance.

In personal care formulations, OPP functions as a preservative by disrupting microbial cell membranes, making it effective against bacteria, yeasts, and moulds at low concentrations. In agricultural applications, it serves as an active biocide in post-harvest treatments and surface disinfectants. It also acts as an antioxidant intermediate in the synthesis of pharmaceutical and cosmetic actives.

This material is supplied as crystalline flakes meeting technical and pharmaceutical-grade specifications. Relevant standards include Ph.Eur. and REACH registration requirements. Typical packaging formats include 25 kg bags and bulk options; documentation including SDS and CoA is available on request.
