The Oléoactif® Collection: Pollution- and Solvent-Free Extraction
Hallstar’s unique and high-performance green Oléo-éco-extraction™ technology, developed and patented in France, was built on this idea of gathering the best from nature to cover a broad range of functions. Through this technology, ingredients of high purity and yield are produced without the use of organic solvents and other pollutants — in a way that is ecologically sustainable. The resulting actives are holistically developed with a combination of several plants and oil-based solvents.
