Sodium Lactate Liquid-CAS 312-85-6 / 72-17-3
Cosmetic Grade Sodium Lactate Liquid is a natural organic salt humectant fermented from natural lactic acid, with a standard 60% high-purity aqueous solution. As an important component of human skin natural moisturizing factors (NMF), it has excellent skin affinity and biocompatibility.
Different from synthetic moisturizers, Sodium Lactate can deeply penetrate the stratum corneum, bind water molecules tightly, reduce skin transpiration and water loss, and solve long-term dryness, tightness and flaking problems fundamentally. In skincare formulas, it exerts dual core values: skin moisturizing and formula stabilization.
It can effectively adjust and balance the pH value of cosmetic systems, optimize formula acid-base environment, improve the stability of active ingredients, and reduce irritation of surfactants and functional additives.
Meanwhile, it gently softens aged keratin, accelerates mild skin metabolism, improves rough, dry and dull skin texture, and makes skin smooth and hydrated. With ultra-mild properties, non-sticky skin feel, wide compatibility and extreme formula stability, Sodium Lactate Liquid is an essential basic functional raw material for high-moisture, low-irritation and high-stability skincare and washing products.
Key Benefits
• Natural NMF Moisturizing, Long-lasting Hydration: Derived from natural fermentation, consistent with human skin moisturizing mechanism, stronger water-locking capacity than glycerin, effectively relieve persistent dryness and keep skin hydrated all day.
• Strengthen Skin Barrier, Reduce Water Loss: Supplement natural moisturizing factors, repair damaged stratum corneum, reduce transepidermal water loss, improve dry peeling and tight skin texture.
• Professional pH Adjustment & Formula Stabilization: Precisely balance cosmetic system pH value, optimize formula environment, stabilize active ingredients and surfactant system, reduce formula deterioration and irritation risks.
• Mild Keratin Softening, Refine Rough Skin: Gently soften aged dead keratin, promote mild skin metabolism, improve rough, dry and dull skin, enhance skin smoothness and delicacy.
• Ultra-mild & Non-sticky, Excellent Skin Feel: Low irritation and high safety, non-greasy and non-sticky after application, effectively improve the greasy feel of traditional moisturizers, refresh and moisturize skin.
• Wide Compatibility & Extreme Stability: Fully water-soluble, compatible with all water-phase formulas and surfactant systems, stable at high and low temperature, no stratification, precipitation or discoloration, suitable for large-scale industrial production.
Applications
• Daily Hydrating & Moisturizing Skincare Series: Core moisturizing raw material for toner, lotion and cream, improve dry and tight skin, maintain long-term skin hydration and elasticity.
• Mild Cleansing Products: Added in facial cleanser, body wash and shampoo, balance formula pH value, reduce surfactant irritation, improve cleaning mildness and post-wash non-tight feeling.
