Sodium Lauroyl Glycinate ●
TL;DR. This ingredient is a mild anionic surfactant used for cleansing, foam, and rinse-off skin feel in face washes, shampoos, and body cleansers. It helps remove oil and soil while leaving less of a stripped feel than many stronger anionic cleansers.
What does Sodium Lauroyl Glycinate do in a cosmetic formula?
This ingredient is a mild anionic surfactant used for cleansing, foam, and rinse-off skin feel in face washes, shampoos, and body cleansers. It helps remove oil and soil while leaving less of a stripped feel than many stronger anionic cleansers.
Is Sodium Lauroyl Glycinate clean?
It is generally accepted in clean-beauty frameworks as a mild, sulfate-free cleanser with low sensitization potential. At higher active levels it can still contribute to eye or skin irritation, which is mainly a formula-level issue.
Is Sodium Lauroyl Glycinate sustainable?
This material is typically made from a fatty acid source such as coconut or palm kernel oil plus an amino acid building block. It is readily biodegradable, with the main sustainability caveat being traceable sourcing for tropical oil feedstocks.
Is Sodium Lauroyl Glycinate COSMOS-approved?
It is generally permitted under COSMOS-natural and COSMOS-organic when made from allowed feedstocks and approved processing steps. Its profile fits Green Chemistry reasonably well because it can use renewable inputs, has good biodegradability, and does not require persistent silicone or fluorinated chemistry.
How does Sodium Lauroyl Glycinate work chemically?
This compound is an N-acyl amino acid salt with a C12 fatty chain attached to glycine, giving it an anionic head group and strong foaming behavior. It is commonly used around 1 to 10% active in rinse-off cleansers, performs best around mildly acidic to neutral pH, and is often paired with amphoteric or nonionic surfactants to tune foam, viscosity, and eye sting.
