4. Product Efficacy

• Antibacterial & Antimicrobial Activity: Caprylhydroxamic Acid exhibits highly selective chelating effects on Fe²⁺ and Fe³⁺, restricting the environmental conditions required for microbial growth, thereby inhibiting microbial proliferation. It can inhibit both gram-negative and gram-positive bacteria, as well as yeasts, Propionibacterium acnes, and Staphylococcus aureus.
• High Safety: Derived from coconut oil, it is a naturally sourced preservative. Its toxicology has been extensively studied, and it can replace traditional preservatives. When compounded with polyols, it forms a "no-added" preservative system, which is widely used in cosmetics and personal care products.
• Excellent Compatibility: CHA is highly compatible with most cosmetic raw materials. Its antimicrobial efficacy is not affected by additives in cosmetics, such as surfactants, proteins, and Chinese herbal extracts.

5. Application Fields

• Cosmetics Industry: Suitable for skincare and haircare products such as gels, serums, lotions, creams, shampoos, and body washes, serving as a preservative. The recommended addition level is 0.05%–0.15%.

6. Packaging & Storage

• Packaging: Typically available in aluminum foil bags (lined with polyethylene plastic bags) of 1kg/bag; other specifications such as 25kg/drum are also provided.
• Storage: Store in a cool, dry place. The shelf life is generally 2 years under proper storage conditions.
