Science
Mechanism of Action
The fermentation process generates long-chain glycolipid congeners that act as biosurfactants. These biosurfactants exert their effect by influencing the cell membranes of microorganisms, providing strong inhibitory activity against yeasts, molds, and bacteria responsible for product spoilage. Furthermore, these glycolipid biosurfactants are hypothesized to support the skin's natural acidic pH, and as a fermented extract, it is noted for its enhanced protective properties and capacity to attenuate cellular damage.

Stability
Studies indicate that at highly acidic pH levels, specifically pH 3.2 and pH 2 when exposed for 8 hours, partial deacylation occurs, leading to a reduced concentration of glycolipids and suggesting decreased stability in very acidic environments.
Safety
Safety Profile
While glycolipids from Dacryopinax spathularia have received FDA GRAS (Generally Recognized As Safe) Notice 740 for use as a food additive with antimicrobial properties, this status does not directly translate to a cosmetic safety assessment. An 'In vitro Skin Corrosion Test' was submitted as part of the GRAS notice, but its specific results concerning skin safety are not publicly available in the provided sources. There is no available information regarding review by the Cosmetic Ingredient Review (CIR) or SCCS.
