Sodium Lauroyl Sarcosinate CAS 137-16-6

Sodium Lauroyl Sarcosinate is a formulation-grade anionic surfactant derived from fatty acids and sarcosine, typically positioned as a mild cleansing and foaming agent in personal care and cosmetic formulations. It is commonly used in shampoo, facial cleanser, toothpaste, and body wash systems where compatibility with other surfactants and low irritation are required. For sulfate-free cleansing systems, Cocoyl Glutamic Acid is a related amino-acid surfactant raw material.

In our supply,it is generally available as aqueous solution or powder form depending on formulation requirements. Standard packaging, batch supply, and documentation such as COA, TDS, and SDS are typically available to support formulation development and bulk procurement.

Packaging

Sodium Lauroyl Sarcosinate is supplied according to its physical form. Liquid grades are typically packed in sealed drums or IBC containers suitable for bulk transport, while solid or powder grades are packed in lined bags or suitable containers to prevent moisture absorption.

All packaging is handled in clean and controlled conditions to maintain product integrity. Packaging arrangements can be adjusted based on order quantity and logistics requirements.

Storage

Store in a cool, dry, and well-ventilated area. Keep containers tightly sealed to avoid moisture uptake or contamination. Avoid direct sunlight and excessive heat during storage and transportation.

Proper storage helps maintain product stability and ensures consistent performance in formulation use.

FAQ - Technical & Supply Chain

  • Q:

    What is Sodium Lauroyl Sarcosinate CAS 137-16-6?

    A: Sodium Lauroyl Sarcosinate is an anionic amino-acid-based surfactant derived from lauric acid and sarcosine. It has CAS 137-16-6, EC No. 205-281-5, and molecular formula C15H28NNaO3, and is used mainly in mild personal-care cleansing formulations.
  • Q:

    What are the main applications of Sodium Lauroyl Sarcosinate?

    A: It is used in shampoo and hair-care products, facial cleansers, body wash, toothpaste, and other mild cleansing systems. It can serve as a primary or secondary surfactant depending on the formulation design.
  • Q:

    Why is Sodium Lauroyl Sarcosinate described as a mild surfactant?

    A: It is selected for good foaming and cleansing performance with a lower-irritation profile compared with many conventional sulfate surfactants. Its mildness benefits depend on the full formulation, pH, concentration, and combination with other surfactants.
  • Q:

    What supply forms, active contents, and pH should be checked for Sodium Lauroyl Sarcosinate?

    A: Commercial grades are commonly supplied as a colorless to light yellow liquid with about 30% active content or as a white powder with about 95% active content. pH is usually alkaline in aqueous solution, often around 7.0-8.5 for a 10% solution, but exact values vary by grade.
  • Q:

    How is Sodium Lauroyl Sarcosinate different from Sodium Lauryl Sulfate or Sodium Lauroyl Isethionate?

    A: Sodium Lauroyl Sarcosinate is a sarcosinate-based anionic surfactant, while Sodium Lauryl Sulfate is a sulfate surfactant and Sodium Lauroyl Isethionate is an isethionate surfactant. They differ in structure, mildness, foaming, pH behavior, and compatibility, so they should be selected by formulation testing rather than used as direct replacements.
