About

Lauroyl sarcosine — a mild N-acyl amino-acid surfactant. Cleanses gently and is common in toothpaste and face wash. Safer than SLS but still an anionic surfactant, so the standard rinse-off cautions apply.

  • Compatible with sensitive formulas
  • Toothpaste-grade safety record

Known concerns

  • Mild irritation possible with overuse
  • Eye sting in rinse-off
