Closed-vessel Digestion of Cosmetics

National and international regulations control concentrations of heavy metals in cosmetics. The goal is to avoid intoxication following regular use of products like lipsticks, nail varnish or toothpaste.


Multiwave 5000 with Rotor 8N is the perfect system to cope with this challenge: highest digestion temperature for complete mineralization, extreme high-pressure stability, and permanent monitoring of the reaction conditions on all vessel positions.

To ensure total destruction of all inert inorganic materials, high temperatures – sometimes for up to one hour digestion time or longer – are needed. Furthermore, total digestion of many cosmetic products requires the use of hydrofluoric acid.
