SLS Powder – Sodium Lauryl Sulphate
SLS Powder (Sodium Lauryl Sulphate) is a widely used anionic surfactant valued for its foaming, cleansing, wetting and detergency properties. It is commonly used by manufacturers and formulators in detergent, cleaning, personal-care and other industrial formulations.
SLS is also known as Sodium Dodecyl Sulphate (SDS) and has the chemical formula C₁₂H₂₅NaO₄S with CAS No. 151-21-3. Commercial SLS powder grades are available with different active-matter specifications, so buyers should select the grade according to the intended formulation and required technical specifications.
LoyalGel supplies SLS Powder for manufacturing and formulation applications, with bulk requirements supported subject to grade and availability.

Applications of SLS Powder
1. Detergent Manufacturing
SLS can be used as a surfactant in detergent formulations where cleansing and foam generation are required.
2. Cleaning Products
It can be incorporated into selected household and industrial cleaning formulations as a cleansing and foaming surfactant.
3. Personal Care Formulations
SLS is used in certain cleansing products such as shampoos, washes and other rinse-off formulations. The appropriate grade and formulation level should be selected based on the intended application.
4. Toothpaste & Oral-Care Formulations
SLS is used as a foaming surfactant in some toothpaste and oral-care formulations.
5. Soap & Cleansing Formulations
It can contribute to foam generation and cleansing performance in suitable soap and cleansing formulations.
6. Industrial Formulations
SLS can also be used as a surfactant, wetting agent or detergent component in selected industrial applications.

SLS Powder vs SLES
This would be a very useful SEO section because people frequently search for the difference.
| SLS Powder | SLES |
|---|---|
| Sodium Lauryl Sulphate | Sodium Laureth Sulphate |
| Usually supplied as powder | Commonly supplied as liquid/paste |
| Anionic surfactant | Anionic surfactant |
| Strong cleansing and foaming | Strong cleansing and foaming |
| No ethoxy chain | Ethoxylated surfactant |
| Used in detergents and selected personal-care formulations | Widely used in shampoos, body washes and detergents |
Don’t position one as universally “better”; the appropriate surfactant depends on the formulation and desired performance. SLS and SLES have different chemical structures and formulation characteristics.
Storage & Handling
Store SLS powder in a cool, dry and well-ventilated area, protected from excessive moisture. Keep the packaging properly closed when not in use to reduce moisture absorption and caking.
Handle according to the SDS/TDS supplied for the specific grade. Appropriate PPE should be used during industrial handling, particularly to minimize eye and skin exposure.
