| Application | Guidance |
|---|---|
| Detergents & cleaners | Primary anionic for powders/bars. Combine with builders/enzymes; adjust sulfate for cost/performance. |
| Personal care (shampoo, toothpaste) | Typical use 3–15% in formula (as supplied). For milder systems, blend with betaines or SLES. |
| Industrial | Wetting/emulsifying for degreasers and latex systems. |
| Dissolution | Charge water first; add SLS slowly with agitation to avoid clumping/foam. Warm water (30–40 °C) speeds wet‑out. |
| Safety | Irritant to eyes/skin; avoid dust. Use local exhaust; consider combustible‑dust controls. See SDS. |
| Storage | Non‑DG. Keep cool/dry; protect from moisture and caking. |
| Applications | Packaging | Docs & Notes |
