What is Sodium lauroyl sarcosinate?
Sodium lauroyl sarcosinate (CAS 137-16-6) is a mild amino acid-derived surfactant. Also marketed as Sarkosyl NL.
Where is Sodium lauroyl sarcosinate used?
- Personal care: primary or co-surfactant in shampoos, facial cleansers and toothpastes
- Toothpaste: compatible with fluoride systems and reduces surface tension
- Shave gels and conditioning cleansers: slip and emulsification, suspending oils and conditioning agents
- Food-contact and industrial cleaning: degreasing and wetting agent
- It functions as a foaming agent, emulsifier and cleansing active.
Good to know: Offers a gentler profile than conventional sulfate surfactants. Low toxicity and biodegradability are procurement requirements.
Commercial specifications
- Clear to pale yellow aqueous solution, typically 30% active content
- Cosmetic/personal care grade meeting industry purity benchmarks
