Molecular model of a cyclodextrin-retinol complex: The retinol molecule fits very snugly inside the gamma-cyclodextrin, but is so long that it sticks out of the ends – two cyclodextrins are therefore used to protect it.

WACKER is the only company in the world capable of producing the highest-purity cysteine from bacteria using a fermentation process. The bacteria produce cysteine non-stop, flushing the amino acid they produce through their cell membrane into the nutrient medium in the fermenter tanks.

Quality control: Drill samples serve to monitor the depth to which the water repellent has penetrated.
