Octanohydroxamic Acid, Caprylhydroxamic Acid-CAS 7377-03-9
Octanohydroxamic Acid (CHA) is a high-efficiency, low-toxic organic hydroxamic acid functional raw material. It features unique metal chelating structure and mild broad-spectrum antibacterial properties, which can effectively chelate heavy metal ions in formula systems, inhibit microbial growth, and improve the long-term stability of daily chemical products. With mild properties, no irritation and excellent compatibility with various cosmetic raw materials, it can replace traditional high-risk preservatives and serve as an ideal green synergistic stabilizer for high-end mild daily chemical formulas and industrial auxiliary systems.
Key Benefits
• Powerful Metal Chelation: Effectively chelates iron, copper and other metal ions, preventing formula discoloration, oxidation and deterioration.
• Mild Broad-Spectrum Antibiosis: Inhibits bacteria and mold growth with mild performance, no irritation to skin and scalp.
• High Formula Stability: Stable performance in conventional pH and temperature ranges, no failure during long-term storage.
• Excellent Compatibility: Compatible with preservatives, surfactants and emulsifiers, easy for formula upgrading and debugging.
• Green & Low-Irritation: Free of harmful additives, low toxicity, compliant with global green cosmetic standards.
• Dual Functional Synergy: Integrates chelating, antibacterial and stabilizing functions to reduce formula additive types.
Applications
• High-End Skincare Products: Used in lotions, creams and essences as chelating stabilizer to prevent product oxidation and discoloration.
• Mild Cleansing Cosmetics: Applied in facial cleanser, body wash and shampoo to synergize antibacterial and extend product shelf life.
• Color Cosmetics: Added in foundation, lipstick and eye makeup to stabilize formula color and improve storage durability.
• Daily Chemical Products: Suitable for hand care, body care and household cleaning products to optimize system stability.
• Industrial Auxiliary Agent: Used as high-efficiency collector and chelating stabilizer for mineral flotation and fine chemical industry.
