Sodium Aurfactin

Concern level

Moderate concern

A sodium salt of surfactin, which is a cyclic lipopeptide biosurfactant. PubChem lists Sodium surfactin C1 with molecular formula C53H91N7Na2O13 and molecular weight 1080.3 g/mol; surfactin itself is described as a surfactant and antimicrobial lipopeptide. Cosmetic use is limited and mostly as a biosurfactant/cleansing helper rather than a mainstream skincare active.

Interactions

incompatible with: Avoid assuming compatibility with very high-electrolyte or highly acidic formulas without supplier validation; surfactant systems can destabilize when paired with incompatible cationic systems or harsh low-pH actives.

Risks & Warnings

Safety data for cosmetic use are limited. As a surfactant, it may be irritating at higher use levels or in sensitive skin, and peptide-based surfactants can be formulation-dependent. Because this exact ingredient is uncommon in cosmetics, conservative use is warranted. ([pubchem.ncbi.nlm.nih.gov](https://pubchem.ncbi.nlm.nih.gov/compound/Sodium-surfactin-C1?utm_source=openai))
