Sodium lauryl sulfoacetate
What is Sodium lauryl sulfoacetate?
Sodium lauryl sulfoacetate (CAS 1847-58-1), known as Lathanol or SLSA, is a mild anionic surfactant derived from lauryl alcohol and sulfoacetic acid.
Where is Sodium lauryl sulfoacetate used?
- Solid and powdered cleansing formats: primary surfactant in bath bombs, solid shampoo bars and dry shampoos
- Liquid rinse-off products: co-surfactant boosting lather in body washes and facial cleansers
- Oral care: foaming and mild degreasing in toothpaste
- Leave-on formulations: emulsification and dispersion for uniform ingredient distribution
- It moderates irritation potential in complex surfactant systems.
- Coarse powder is particularly useful for bath bomb and dry blending production because it can help reduce dust during use and improve the production experience.
- For dissolution, coarse powder should be mixed into at least 5 times its amount of water and heated above 80°C with occasional stirring until it dissolves clear.
Good to know: Gentler on skin than conventional sulfate surfactants, with a low irritation profile; not to be confused with SLS.
Formulation notes
- In solid shampoo formulations, typically used at concentrations between 2% and 8% depending on desired foaming and cleaning properties.
- Can be combined with other surfactants such as coco-glucoside or cocamidopropyl betaine to enhance mildness and foam stability.
- Considered milder to the skin than ethoxylated alcohol sulfates.
- Incompatible with strong oxidizing agents.
Typical specification
- Minimum active matter content of 75%.
- pH of approximately 5.0 to 7.5 in a 1% solution.
- Offered in cosmetic grade.
Regulatory status
- Falls under the EU Cosmetics Regulation 1223/2009.
- INCI name is Sodium Lauryl Sulfoacetate.
- Classified as Hazard under GHS because it causes serious eye damage (H318).
Storage, packaging and handling
- Should be stored in a cool, dry place away from direct sunlight and moisture to maintain product integrity.
