Sodium Lauryl Sulphate (SLS) – Anionic Surfactant

Sodium Lauryl Sulphate (SLS), also known as sodium dodecyl sulfate, is an organic compound with the formula C₁₂H₂₅SO₄Na. It is one of the most commonly used surfactants due to its ability to effectively break surface tension and emulsify oils. In cosmetics, it’s a key ingredient in shampoos, body washes, facial cleansers, and toothpaste, providing rich lather and cleansing action.

Industrially, SLS is valued in agrochemicals, textile processing, degreasers, and cleaning agents for its cost-effectiveness and efficiency. At MDNR Resources, our SLS is available in high-purity pharmaceutical, cosmetic, and technical grades, manufactured under strict GMP conditions and compliant with international safety standards.

Ethoxylation & Sulfonation Process

1. Derived from lauryl alcohol, which is obtained from coconut or palm kernel oil

2. Sulfonation with sulfur trioxide (SO₃) to produce lauryl sulfate

3. Neutralization with sodium hydroxide to yield Sodium Lauryl Sulphate

4. Spray-dried into powder, needles, or paste forms depending on end-use

1. Is Sodium Lauryl Sulphate safe for skin use?

Yes, in cosmetic concentrations (typically <2%), SLS is considered safe by regulatory authorities like FDA and EU SCCS. Sensitive skin types may opt for milder alternatives.

2. What is the difference between SLS and SLES?

SLS is stronger and more foaming, while SLES (Sodium Laureth Sulfate) is milder and often preferred for sensitive skin formulations.

3. Can SLS be used in pharmaceutical applications?

Yes. Pharma-grade SLS is used as an emulsifier and wetting agent in tablets and creams.

4. What forms of SLS are available?

We supply SLS in powder, needle, and paste forms, based on your formulation requirements.
