Sodium Lauroyl Sarrnsinate ●
TL;DR. This ingredient is a mild anionic surfactant used for cleansing and foam, especially in face washes, shampoos, toothpastes, and body washes. It helps lift oil and soil while giving a finer, creamier lather than many stronger sulfate-type cleansers.
What does Sodium Lauroyl Sarrnsinate do in a cosmetic formula?
This ingredient is a mild anionic surfactant used for cleansing and foam, especially in face washes, shampoos, toothpastes, and body washes. It helps lift oil and soil while giving a finer, creamier lather than many stronger sulfate-type cleansers.
Is Sodium Lauroyl Sarrnsinate clean?
From a clean-beauty perspective, it is generally accepted and usually considered lower-irritation than harsher anionic cleansers, though it can still sting eyes or irritate compromised skin at higher levels. The main quality-control caveat is control of nitrosamine-related impurities during manufacturing and storage.
Is Sodium Lauroyl Sarrnsinate sustainable?
This material is commonly made from a fatty acid source such as coconut or palm kernel plus an amino-acid-derived component, so sourcing depends on the supplier. It is expected to be readily biodegradable, with the main sustainability question being traceable palm or coconut feedstock rather than environmental persistence.
Is Sodium Lauroyl Sarrnsinate COSMOS-approved?
It is generally permitted under COSMOS-natural and COSMOS-organic when made from allowed feedstocks and compliant processing, so it has partial-to-good natural-standard alignment. Its Green Chemistry fit is supported by biodegradability and efficient surfactant performance, with some compromise from chemical derivatization and feedstock traceability requirements.
How does Sodium Lauroyl Sarrnsinate work chemically?
The molecule is an N-acyl amino acid salt, combining a C12 fatty chain with a charged carboxylate head group to give water solubility and anionic cleansing behavior. It is typically used around 1 to 10 percent active matter depending on product type, performs best near mildly acidic to neutral pH, and is often blended with amphoteric or nonionic surfactants to improve mildness and foam quality.
