Description

Siloxanes And Silicones, Hydroxy Me, Hydroxy-Terminated, Ethers With Ascorbic Acid is a specialized organosilicon compound where a hydroxy-terminated siloxane backbone is chemically modified with ascorbic acid (vitamin C) via an ether linkage. This unique molecular architecture combines the thermal stability, flexibility, and surface activity of silicones with the potent antioxidant properties of ascorbic acid. It is engineered for advanced formulations where oxidative stability and silicone performance are critical. Key industrial users include manufacturers of high-performance personal care products, specialty polymer additives, and advanced coating systems.

Application

• Antioxidant Additive for Silicone Polymers: Imparts enhanced resistance to thermal and oxidative degradation in silicone rubbers, resins, and gels.
• Stabilizer in Cosmetic & Personal Care: Used in premium skincare, sun care, and haircare formulations to protect active ingredients and extend product shelf life.
• Functional Modifier for Coatings: Enhances the weatherability and longevity of protective coatings and paints by scavenging free radicals.
• Pharmaceutical & Nutraceutical Excipient: Serves as a stabilizing carrier or delivery agent for sensitive, oxidation-prone active pharmaceutical ingredients (APIs).
• Specialty Lubricant & Grease Component: Contributes to the oxidative stability of high-temperature silicone-based lubricants.
• Adhesive & Sealant Formulation: Improves the long-term durability and performance of silicone adhesives and sealants exposed to environmental stressors.

Quality Control

Our production of Siloxanes And Silicones, Hydroxy Me, Hydroxy-Terminated, Ethers With Ascorbic Acid (CAS 135800-41-8) adheres to a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency in composition, antioxidant activity, and purity. Certificates of Analysis (COA) documenting key parameters such as assay, hydroxyl value, and viscosity are provided to guarantee the material meets your specific technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its easily oxidized nature, minimize headspace in opened containers and handle under inert gas when possible to maintain product efficacy.
