Description

(2-Hydroxy-4-Methoxy-Phenyl)-(4-Hydroxyphenyl)Methanone is a high-purity organic compound, also known as Benzophenone-8, valued for its ability to absorb specific wavelengths of ultraviolet light. This makes it a critical functional ingredient for formulators requiring precise photostability and protection. It is primarily sought after by manufacturers in the personal care, cosmetic, and specialty chemical industries for advanced sunscreen and UV-filtering applications.

Application

• Broad-Spectrum Sunscreen Formulations: Acts as an effective UV filter in sun care products, lotions, and creams.
• Photostabilizer for Polymers & Coatings: Protects plastics, paints, and industrial coatings from UV-induced degradation.
• Cosmetic & Skincare Products: Used in anti-aging creams, foundations, and lip balms requiring UV protection.
• Hair Care Products: Incorporated into shampoos, conditioners, and styling products to prevent color fading and protein damage from sunlight.
• Packaging Materials: Enhances the light stability of sensitive products by incorporating into films and containers.
• Industrial Additive: Serves as an intermediate or additive in the synthesis of other light-absorbing compounds.

Quality Control

Our (2-Hydroxy-4-Methoxy-Phenyl)-(4-Hydroxyphenyl)Methanone is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing, including HPLC and spectroscopic methods, to ensure it meets high-purity standards suitable for cosmetic and industrial applications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which could affect product quality and performance.
