What is the main purpose of Laureth-3 in skincare products?
Laureth-3 acts as an emulsifier, helping to mix oil and water ingredients that would otherwise separate. This creates a smooth, consistent product texture and ensures even distribution of other ingredients.
Is Laureth-3 considered safe for sensitive skin?
While generally considered safe, some individuals with very sensitive skin might experience mild irritation, especially if used in higher concentrations or in leave-on products. Patch testing is always recommended.
