Introduction

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. As a food additive, it has E number E231.

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.
 

Odour – “smell”

OPP (MS) produced from MPP can have a very marked “odour”, or smell, when in large quantities. For example, in a warehouse stock. OPP (CNS) from Cyclohexanone has no featured “odour” or smell.

We advise that this feature and the effect on any final product produced from OPP should be carefully considered.
