SCENEDERM® - Scenedesmus obliquus liquid extract

A liquid extract from Scenedesmus, which is a cosmopolitan unicellular microalga from the chlorophycae class and from the scenedemacae family. It is non-mobile, measuring approximately 5 to 30 micrometres in length and 8 to 10 micrometres in diameter.

Scenedesmus contains a significant amount of chlorophyll a and b, pigments from photosynthesis, and carotenoids. This microalga carries many molecules of interest:

- It is very rich in lutein

- It has a high concentration of lipids and sterols and, more specifically, interesting levels of sterols Δ5 and Δ7, and phytols (BHT, BHA).

- It is very rich in proteins: the dry matter of Scenedesmus contains 55 to 60% of proteins, or an amount as significant as that present in Spirulina which is already used as a food supplement for its richness in protein.

- It is rich in Vitamins B1, B2, B7, B9, B12 and C.

- It contains Polyphenols and flavonoids (quercitrin and rutin).

To optimize the qualities of resistance and production of its molecules of interest, AlgoSource selects its strain carefully. Moreover, each step is validated during the culture process by microscopic control. Scenedesmus is then harvested by mechanical means without any chemical additives and filtered to remove impurities. The harvest is then ensured by centrifugation which makes it possible to obtain a moist paste that will serve as raw material for the AlgoSource concentrated extracts.

From this biomass, AlgoSource extracts molecules of interest without fermentation or additives, making it possible to obtain water-soluble constituents. The Scenedesmus extract, whose concentration varies depending on the needs of the customers, is finally stabilized cold using a sterilizing microfiltration process. It offers AlgoSource customers access to an ingredient with very high added value that is also 100% natural.

The major cosmetic benefits of this microalgae notably include hydration, UV protection, cellular stimulation, anti-tyrosinase activity, reduction of melanin synthesis and even acne prevention.
