Fermira™ RedOil

Fermira™ RedOil is an oil obtained from Rhodotorula toruloides yeast biomass through a fermentation process. Its lipid fraction consists primarily of triglycerides, with oleic acid as the predominant fatty acid. The ingredient also naturally contains carotenoids, sterols and polyphenols.

In cosmetic formulations, it primarily functions as an emollient. It can enrich the lipid phase of creams, serums, lotions and hair care products, helping to improve softness, smoothness and application properties. Naturally occurring carotenoids give the oil its characteristic red colour, the intensity of which in the finished formulation depends on the use level and the other ingredients present.

In addition to its lipid function, the ingredient has also demonstrated biological activity in in vitro studies. Keratinocyte and fibroblast models have shown effects on the expression of genes associated, among others, with hydration, response to oxidative stress and extracellular matrix remodelling processes. This allows RedOil to be used not only as a component of the oil phase, but also in formulations designed to support anti-ageing skin care and overall skin condition.

Its fermentation-derived origin, distinctive lipid profile and naturally occurring accompanying compounds differentiate it from conventional plant oils. 

Key information for formulators
