Science

Mechanism of Action

Functioning primarily as a nonionic surfactant, emulsifier, and solubilizer, LAURETH-10 reduces the surface tension between immiscible ingredients, allowing for the stable integration of oil and water components. This action is vital for creating uniform creams and lotions. As a surfactant, it enables dirt and oils to be efficiently emulsified and rinsed away from skin and hair. Additionally, it aids in dissolving poorly soluble substances, can act as a rheology modifier, and boosts foam formation.

Sensitization risk Low

The CIR Expert Panel confirms LAURETH-10's safety in cosmetic products when formulated to be non-irritating. While there is a historical concern regarding 1,4-dioxane, a potential carcinogenic by-product of ethoxylation, reputable manufacturers rigorously purify products to minimize or eliminate this contaminant. Generally well-tolerated by most skin types, concentrations exceeding 5% may lead to mild irritation, particularly in individuals with sensitive or compromised skin barriers.
