Quality Control is systematic and rigorous.
Checking by experts is mandatory for each entry and exit of product. The control is analytical: physico-chemical analysis, chromatography and mass spectrometry and organoleptic : colour and odour.
In-line monitoring is carried out to measure density, refraction and colour-matching. Traceability of our deliveries is ensured by keeping batch samples of all manufacturings, which we retain for 3 years.
