Description

Sodium Lactate is the sodium salt of lactic acid, a versatile organic compound widely utilized for its humectant, buffering, and antimicrobial properties. This high-purity ingredient is essential for formulating products that require precise pH control, moisture retention, and enhanced shelf stability. It serves as a critical component for manufacturers in the pharmaceutical, personal care, and food industries seeking reliable, compliant raw materials.

Application

• Pharmaceutical Formulations: Used as an alkalizing agent, electrolyte source, and excipient in intravenous solutions, dialysis fluids, and topical products.
• Cosmetics & Personal Care: Acts as an effective humectant and moisturizer in skin creams, lotions, and hair care products to improve hydration.
• Food & Beverage Industry: Employed as a flavor enhancer, pH regulator, and shelf-life extender in meat products, dressings, and beverages (FCC grade).
• Biotechnology & Cell Culture: Serves as a component of buffer systems and nutrient media in fermentation and bioprocessing applications.
• Industrial Applications: Functions as a biodegradable de-icing agent, a plasticizer, and a component in electroplating baths.
