What is Lauramine Oxide?

Lauramine Oxide is a synthetic amphoteric surfactant, chemically known as N,N-dimethyldodecan-1-amine N-oxide, produced by oxidizing lauryl dimethylamine with hydrogen peroxide. It appears as a clear to pale yellow liquid and is commonly incorporated into rinse-off cosmetics like shampoos, body washes, hand soaps, and facial cleansers at concentrations typically below 10%. This ingredient functions by reducing surface tension to enable emulsification of oils and dirt into micelles for easy rinsing. Its pH-dependent behavior allows it to act as non-ionic or cationic, providing both cleansing power and mild conditioning effects. As a foam booster, it creates stable, creamy lather; as a hydrotrope, it solubilizes fragrances and oils in water; and as an antistatic agent, it minimizes flyaways on hair. It also aids viscosity control for optimal texture in formulations.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

Fragrance ingredient

Contributes scent character and/or masks base odors, shaping the overall sensory experience of the formula (subject to allergen and IFRA considerations).

Hair conditioning

Improves softness, shine, and manageability by reducing friction and static; commonly achieved with cationic agents, silicones, oils, or conditioning polymers.

Surfactant

Lowers surface tension to enable cleansing, emulsifying, and foaming; central to shampoos, body washes, and many emulsions and micellar systems.

Cleansing agent

Removes dirt, oil, and impurities by lowering surface tension and forming micelles, enabling soils to be lifted and rinsed away from skin, hair, or teeth.

Foam booster

Enhances foam volume and creaminess and can stabilize lather, improving sensory feel and perceived cleansing in shampoos and wash-off products.

Hydrotrope

Improves solubility of poorly soluble ingredients (like fragrances) in water-based systems, helping maintain clarity and prevent separation or cloudiness.

Antistatic agent

Reduces static electricity and flyaways by improving surface conductivity, enhancing hair manageability and smoothness in conditioners and styling products.

Viscosity controlling agent

Adjusts thickness to the desired level for stability and usability, improving dispensing, suspension, and texture across many formulation types.

Benefits

Delivers effective yet gentle cleansing by lifting dirt and excess oils.

Enhances foam quality for a luxurious lathering experience in washes.

Reduces static electricity, improving hair smoothness and manageability.

Who It's For
