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.

Laureth-3

Laureth-3 is a synthetic fatty alcohol ethoxylate that functions primarily as an emulsifier and surfactant in cosmetic formulations. It helps to blend oil and water components, creating stable product textures. It can also contribute to the foaming properties of cleansers.
