This anionic surfactant, derived from natural sarcosine, offers excellent mildness, high foaming power, and superior lime‑soap dispersion. It is widely used in:
| Sector | Typical Uses |
|---|---|
| Personal Care | Shampoos, baby washes, facial cleansers, shower gels, micellar waters |
| Oral Care | Toothpastes (plaque dispersion, active ingredient suspension) |
| Shaving Products | Shaving foams and gels (creamy rich lather) |
| Household Cleaners | Dishwashing liquids, multi‑purpose cleaners |
| Industrial Applications | Wetting agents, emulsifiers in polymerization, textile processing, corrosion inhibition |
| Biochemical Research | Cell lysis and protein solubilization (as Sarkosyl) |
Mild & skin‑friendly – low irritation, suitable for sensitive skin and baby products
Excellent hard water tolerance – effective even in high‑mineral water
Synergistic – works well with other surfactants (anionic, non‑ionic, amphoteric)
Biodegradable – environmentally acceptable
Classification: Not classified as dangerous under normal transport (for aqueous solution with < 60% active), but may cause eye/skin irritation.
Hazard statements:
H315 – Causes skin irritation
H319 – Causes serious eye irritation
Precautionary statements: P264, P280, P302+P352, P305+P351+P338
Transport: Not regulated as dangerous goods for 30% solution (check local regulations for concentrated >50%)
