Sodium Lauroyl Sarcosinate

Sodium Lauroyl Sarcosinate (SLSa) – Mild, Efficient, Multifunctional Surfactant

Sodium Lauroyl Sarcosinate is a highly versatile amino-acid-based surfactant known for its excellent cleansing power, mildness, and antimicrobial performance. Thanks to its unique molecular structure, it delivers strong detergency while remaining gentle on skin and mucous membranes, making it widely used across personal care, oral care, industrial cleaning, and specialty chemical applications.

Key Features

• High Cleaning & Degreasing Efficiency
  Effectively removes oils, proteins, and particulate residues while maintaining a mild skin profile.

• Naturally Mild & Skin-Friendly
  Slightly acidic (pH 5.5–6.5), making it suitable for sensitive, oily, and acne-prone skin.

• Fine, Rich, Creamy Foam
  Creates dense, luxurious lather comparable to sulfate-based systems, without irritation.

• Excellent Compatibility
  Compatible with anionic, nonionic, amphoteric, and silicone conditioning agents.

• Antimicrobial Performance
  Inhibits the growth of Lactobacillus fermentum and other microorganisms, contributing to oral hygiene and product stability.

• Biodegradable & Eco-friendly
  Readily biodegradable; suitable for clean-label and sulfate-free formulations.
