What is Lauryl hydroxysultaine?
Lauryl hydroxysultaine (CAS 13197-76-7) is an amphoteric betaine-type surfactant derived from lauryl chemistry. Also marketed as ORISTAR LHS and MACKAM LHS.
Where is Lauryl hydroxysultaine used?
- Personal care: foam booster, viscosity modifier and conditioning agent
- Shampoos, body washes and liquid hand soaps: enhances foam density
- Hair care rinse-off products: conditioning and antistatic properties
- Textile and leather processing: emulsification and soil removal in scouring and degreasing baths
- Paper manufacturing controls foam and improves fiber dispersion in wet-end processing.
Good to know: The surfactant stabilizes lather while reducing the irritation potential of primary surfactant systems; particularly useful where mildness is a formulation requirement.
Commercial specifications
- Aqueous solution, typically 30–50% active content
- Drums and intermediate bulk containers (IBCs)
