Sodium Cocoyl Sarcosinate

Product Description

Sodium Cocoyl Sarcosinate is a high-performance, anionic amino acid surfactant derived from natural coconut fatty acids and sarcosine, manufactured at our specialized facility to ensure stable B2B supply. This ingredient functions through a unique sarcosinate structure that provides superior flash foam and creaminess while maintaining exceptional mildness and compatibility with the skin's biological barrier. As the global personal care market pivots toward "Sulfate-Free" and "Derm-Focused" cleansing, this ingredient offers formulators a strategic solution for high-end sensory profiles.

Product Specification

• INCI Name: Sodium Cocoyl Sarcosinate
• CAS No.: 156572-81-5 / 61791-59-1
• Chemical Type: Amino Acid Surfactant

Key Benefits & Applications

• Exceptional Flash Foam: Unlike many mild surfactants, it produces an immediate, voluminous, and stable foam even in the presence of oils or sebum.
• Advanced Mildness: Exhibits low protein denaturation potential, making it ideal for formulations targeting sensitive skin and reducing trans-epidermal water loss (TEWL).
• Acidic Stability: Maintains excellent performance and solubility in slightly acidic conditions (pH 5.0 – 6.5), which is optimal for skin-neutral products.
• Applications: Extensively used in premium facial cleansers, sulfate-free shampoos, shaving foams, and high-performance baby care products.

Formulation Guidelines

• Recommended Dosage: 5.0% – 25.0% as a primary surfactant; 1.0% – 5.0% as a secondary surfactant to boost foam quality.
• Viscosity Management: Can be effectively thickened when used in synergy with amphoteric surfactants or specific polymeric thickeners.
• Processing: Suitable for cold processing; add to the water phase under gentle agitation to avoid excessive aeration.
• Synergy: Combine with Cocamidopropyl Betaine for enhanced viscosity control and a softer, more moisturized skin feel.
