Sodium Lauryl Sulfate is a strong anionic surfactant used where high detergency, wetting, and foam generation are required.
Sodium Lauryl Sulfate (SLS) is a high-foaming anionic surfactant commonly used in cleaning and rinse-off systems. It provides strong detergency and wetting but can be more irritating than milder surfactant systems, so formulation context, concentration, co-surfactants, and finished-product exposure should be reviewed carefully.
Commercial grades may be supplied as powder, needles, or aqueous solution. Active matter, sodium sulfate content, residual alcohol, and particle form are supplier dependent.
| Property | Value | Unit | Source / Method |
|---|---|---|---|
| Appearance | White to off-white solid or aqueous solution | N/A | Supplier dependent |
| Active Matter | 28 - 95 | % | Varies by grade |
| pH | 7 - 10.5 | N/A | As supplied; supplier dependent |
| Solubility Water | Water soluble | N/A | Typical behavior |
| Ionic Character | Anionic | N/A | Surfactant class |
| Foam Height | High | N/A | Application dependent |
status: compatible | Often blended to improve foam and mildness profile
status: compatible | Common in mixed surfactant systems
status: avoid | Avoid strongly acidic systems unless supplier data supports stability

Review and verify the supplier SDS/TDS before handling, scale-up, or commercial use. Concentrated SLS can cause eye, skin, and respiratory irritation; use suitable PPE and dust controls for dry grades.
Use must be assessed by product category, impurity profile, exposure route, and local requirements. Confirm current regulatory status from supplier documentation before market launch.
