Frequently asked questions

Is Magnesium Laureth Sulfate a sulfate?

Yes, it is a sulfate-based surfactant, but it is generally considered milder than some other sulfates like Sodium Lauryl Sulfate due to its larger molecular size and magnesium salt.

Is Magnesium Laureth Sulfate suitable for sensitive skin?

While generally milder, individuals with very sensitive skin may still experience some irritation, especially in rinse-off products. Patch testing is always recommended.
