The joint control of these two parameters is crucial. On one hand, what may seem like a minor deviation
in physicochemical quality can significantly impact the olfactory quality. On the other hand, achieving
high physicochemical quality does not guarantee the best olfactory quality.
The expertise of Société Grassoise de Parfumerie, in both raw materials and perfume composition, is a
considerable asset: we can conduct the most accurate control of physicochemical quality, as well as olfactory quality.
SGP2 and SGP3 sites both feature a control and analysis laboratory. Our equipment allows us to cover the full spectrum of physicochemical control: refractometers, polarimeters, densimeters, flash point, gas
chromatographs, mass spectrographs…
As for our olfactory controls, they rely on the excellence of human judgement. They are supported by a panel of 5 experienced individuals.
