Sodium Surfactin

Sodium Surfactin is the sodium salt of surfactin, a fermentation-derived lipopeptide biosurfactant used in cosmetics as a mild surfactant and emulsifying agent.

What it is

Sodium Surfactin is the sodium salt of surfactin, a cyclic lipopeptide produced by Bacillus bacteria. As a biosurfactant it lowers surface tension efficiently and is used to emulsify and gently cleanse, often valued as a naturally derived alternative to conventional surfactants. It is typically used at low levels to help stabilize emulsions and improve formula texture.

Safety & warnings

As a biosurfactant used at low concentrations, it is generally considered mild and well tolerated, and is often selected for gentle, fermentation-based formulas.

Origin & sourcing

Microbially derived. It is produced by bacterial fermentation, most commonly using Bacillus subtilis, and isolated as its sodium salt.

Questions everyone asks

What is Sodium Surfactin?

It is the sodium salt of surfactin, a lipopeptide biosurfactant made by bacterial fermentation, used as a mild surfactant and emulsifier.

Why use a biosurfactant like Sodium Surfactin?

It emulsifies and cleanses effectively at low levels and is favored as a naturally derived, gentle alternative to conventional surfactants.
