2-Phenylphenol, or o-phenylphenol, is an organic compound that consists of two linked benzene rings and a phenolic hydroxyl group.[1][2] It is a white or buff-colored, flaky crystalline solid with a melting point of about 57 °C. It is a biocide used as a preservative under the trade names Dowicide, Torsite, Fungal, Preventol, Nipacide and many others.

History
2-Phenylphenol (ortho-phenylphenol, OPP), and sodium o-phenylphenate, SOPP, were first evaluated by the 1962 JECFA for their use for the post-harvest treatment of fruits and vegetables to protect against microbial damage during storage and distribution in commerce.[3]
Uses
The primary use of 2-phenylphenol is as an agricultural fungicide. It is generally applied post-harvest. It is a fungicide used for waxing citrus fruits. It is no longer a permitted food additive in the European Union, but is still allowed as a post harvest treatment (in only 4 EU countries).
It is also used for disinfection of seed boxes. It is a general surface disinfectant, used in households, hospitals, nursing homes, farms, laundries, barber shops, and food processing plants. It can be used on fibers and other materials. It is used to disinfect hospital and veterinary equipment. Other uses are in rubber industry and as a laboratory reagent. It is also used in the manufacture of other fungicides, dye stuffs, resins and rubber chemicals.
2-Phenylphenol is found in low concentrations in some household products such as spray disinfectants and aerosol or spray underarm deodorants.
Eye contact can cause severe irritation and burns with possible eye damage. For some individuals, 2-phenylphenol can also irritate the skin.[4] It is one of the chemicals that the Hyperactive Children's Support Group recommends be eliminated from the diet of children (Needs citation).
The sodium salt of orthophenyl phenol, sodium orthophenyl phenol, is a preservative,[5] used to treat the surface of citrus fruits to prolong shelf life.[3]
Orthophenyl phenol is also used as a fungicide in food packaging and may migrate into the contents.[6]
