Sodium Lauroamphodiacetate
What is Sodium Lauroamphodiacetate?
Sodium Lauroamphodiacetate is a mild, amphoteric surfactant derived from lauric acid and diaminoacetic acid, commonly used in personal care products for its excellent foaming and cleansing properties. It functions by reducing surface tension to remove dirt and oils while being gentle on the skin and eyes, making it a popular choice in shampoos, body washes, and facial cleansers. Its amphoteric nature allows it to be compatible with both anionic and cationic ingredients, enhancing formulation stability.
Roles in Formulation
This ingredient serves the following purposes in cosmetic formulations:
Foam booster
Enhances foam volume and creaminess and can stabilize lather, improving sensory feel and perceived cleansing in shampoos and wash-off products.
Hair conditioning
Improves softness, shine, and manageability by reducing friction and static; commonly achieved with cationic agents, silicones, oils, or conditioning polymers.
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.
Surfactant
Lowers surface tension to enable cleansing, emulsifying, and foaming; central to shampoos, body washes, and many emulsions and micellar systems.
Foaming
Generates foam during use to help distribute the product and lift soils; typically delivered by surfactants that create stable bubbles under agitation.
