Sodium Lauroyl Hydrolyzed Silk ●
TL;DR. This ingredient is a mild anionic surfactant and conditioning cleanser, used to help lift oil and soil while leaving a softer after-feel than many standard sulfate-type cleansers.
What does Sodium Lauroyl Hydrolyzed Silk do in a cosmetic formula?
This ingredient is a mild anionic surfactant and conditioning cleanser, used to help lift oil and soil while leaving a softer after-feel than many standard sulfate-type cleansers.
Is Sodium Lauroyl Hydrolyzed Silk clean?
From a clean-beauty perspective, it is generally viewed as a mild cleansing ingredient with low irritation potential at typical rinse-off levels. It can create friction for vegan standards and for brands that screen closely for animal-derived inputs or trace processing residues.
Is Sodium Lauroyl Hydrolyzed Silk sustainable?
This material is typically made from a fatty acid source plus a hydrolyzed protein source, so its footprint depends on the origin and traceability of both inputs. It is expected to be more biodegradable than persistent silicone or fluorinated materials, but palm-linked fatty feedstocks and animal-derived sourcing are common supply-chain considerations.
Is Sodium Lauroyl Hydrolyzed Silk COSMOS-approved?
It is not a straightforward COSMOS-organic fit because it is a chemically modified surfactant rather than a simple natural extract. It may be acceptable in COSMOS-natural only when the supplier can document compliant sourcing, allowed processing, and impurity controls, so DARE would treat it as conditionally aligned rather than automatically green.
How does Sodium Lauroyl Hydrolyzed Silk work chemically?
The molecule is an amphiphilic sodium salt made by attaching a fatty acyl group to short protein fragments, giving it both cleansing and film-forming behavior. It is used mainly in rinse-off systems, performs best in mildly acidic to neutral formulas, and is commonly paired with amphoteric or nonionic surfactants to moderate foam feel and reduce irritation potential.
