Science

Mechanism of Action

This ingredient functions by reducing the surface tension of liquids, facilitating effective cleansing by dislodging dirt, oil, and impurities from the skin. It enhances the volume, texture, and stability of foam, acts as an emulsifier to blend disparate ingredients, and offers mild conditioning benefits to both skin and hair.

Stability

Lauramine Oxide demonstrates optimal effectiveness within a pH range of 6.0 to 8.0, with its performance diminishing in highly alkaline or acidic environments. It is versatile across acidic, neutral, and alkaline formulations. For optimal integration, it should be mixed into the water phase and can withstand heat up to 80°C. However, excessive agitation or temperatures above 80°C should be avoided to prevent bubble formation.

Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has concluded Lauramine Oxide is safe for use in rinse-off products and restricted its concentration to 3.7% in leave-on products due to a potential for mild cumulative irritation. Formulations must be devoid of potentially carcinogenic nitrosamine compounds and nitrosating agents. While concentrated forms can lead to skin irritation and serious eye damage, correctly formulated products at recommended concentrations present low risks for skin and eye irritation, allergies, and carcinogenicity.
