EagleBurgmann offers reliable sealing solutions for the production of shampoo.

Whether it’s for more volume, for more sheen, for dyed hair or for a well-groomed beard – the choice of shampoos seems practically endless nowadays. Only few people ever think about what happens before their favorite product is placed on the supermarket shelf. The production of hair wash products can be a great challenge for cosmetics companies. A variety of raw materials with different physical and chemical properties has to be processed. Canan Kozmetik, a sub-brand of L’Oréal based in Istanbul, faced a long period of constant downtimes and high maintenance costs due to seal failures. A solution was found by experts from EagleBurgmann in the form of cartridge seals with the innovative DiamondFace® Technology.
