Euglena/Oleic Acid Ferment

Euglena/Oleic Acid Ferment is a fermentation-derived ingredient produced by culturing the microalga Euglena with oleic acid, used as a skin-conditioning agent.

What it is

This material is created by fermenting Euglena, a single-celled photosynthetic microorganism, in the presence of oleic acid. The resulting ferment is used in skincare as a conditioning ingredient that contributes lipids and biomass-derived components to the formula. Euglena is valued in cosmetics for its content of beta-glucan (paramylon) and fatty acids.

Safety & warnings

As an oleic-acid-containing ferment, it includes an unsaturated fatty acid that can be comedogenic and may not suit acne-prone skin at higher levels. It is generally well tolerated as a conditioning ingredient.

Origin & sourcing

Biotechnological; produced by fermentation of cultured Euglena microalgae together with oleic acid, a common unsaturated fatty acid.
