Disodium Lauroyl Sarcosinate
What is Disodium Lauroyl Sarcosinate?
Disodium Lauroyl Sarcosinate is a mild anionic surfactant derived from sarcosine (an amino acid) and lauric acid, commonly used in cleansers, shampoos, and foaming products for its excellent foaming properties and gentle cleansing action. It effectively removes dirt, oil, and impurities without stripping the skin's natural moisture barrier, making it suitable for sensitive skin formulations. This ingredient is often combined with other surfactants to enhance foam stability and mildness in personal care products.
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.
