Frequently Asked Questions
Answers in plain language
Is sodium lauryl sulfate banned in Europe?
No. Sodium lauryl sulfate (SLS) is permitted in EU cosmetics with no specific concentration cap under Regulation (EC) 1223/2009. It is widely used as a surfactant in shampoos, cleansers and toothpaste. The "SLS-free" marketing trend is driven by consumer perception of irritation rather than by regulatory restriction.
What are the side effects of sodium lauryl sulfate?
At higher concentrations and long contact times, SLS can cause skin irritation, dryness and stinging, particularly on sensitive or already-compromised skin. In rinse-off products at typical concentrations the exposure time is short and most users tolerate it well. People with sensitive scalp, eczema, or mouth ulcers may prefer milder surfactants like sodium laureth sulfate or coco-glucoside.
