MAGNESIUM COCO-SULFATE
Safety score · 0–100
Fine
Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.
A coconut-derived sulfate surfactant often marketed as a milder alternative to SLS. The magnesium counter-ion offers some benefits, but research shows the irritation profile is broadly similar.
Skin benefits
- Coconut-derived alternative to harsher sodium lauryl sulfate
- Provides effective cleansing and foam
- Magnesium counter-ion may produce a slightly milder feel
- Often used in solid shampoo bars and bar soaps
Known concerns
- Independent studies suggest similar irritation potential to SLS at equal concentrations
- Can be drying on already dry skin or coily hair
- Marketing positioning as inherently gentler is not fully supported by research
- May strip the scalp microbiome with frequent use
