Product Name:
o-Phenylphenol (OPP), ≥99.5% Purity, White Crystalline Biocide and Preservative
Product Description:
o-Phenylphenol (OPP) is a high-purity organic compound known for its strong antimicrobial and antifungal properties. Produced as a white crystalline powder or flakes, this material is slightly soluble in water and readily soluble in ethanol and organic solvents. It offers reliable performance as a biocide and preservative across a wide range of industrial and household applications.
With a purity of ≥99.5% and a sharp melting point between 56–58 °C, our OPP is suitable for use in high-efficiency disinfection formulations, plastic and rubber mold inhibitors, and surface sanitizers. It is also widely used as a preservative additive in coatings, leather processing, adhesives, and cleaning products.
Manufactured under strict quality control standards, our OPP offers low impurities, stable composition, and excellent long-term storage properties. Supporting documents including COA, MSDS, and REACH compliance are available upon request.
