The industry’s most powerful and effective yeast inhibitor and microbial control agent.
VELCORIN® is the trade name for dimethyldicarbonate (DMDC), a microbial control agent produced by LANXESS®. VELCORIN has been used in the U.S. since 1988. Its approvals include use in wine, low-alcohol wine, non-alcoholic wine, cider, juice, juice sparklers, sports drinks, and ready-to-drink teas. VELCORIN is very effective at low dosages against a broad range of yeast, bacteria and molds. Unlike other chemical preservatives, VELCORIN is non-persistent and does not affect cider taste, aroma or color. VELCORIN can remain active for several hours thereby helping to eliminate contamination from other sources such as bottles, closures and filling equipment

Velcorin must be dosed into the beverage using an approved Velcorin dosing machine. Due to the unique physical properties of Velcorin, LANXESS Corp. requires the use of approved dosing machines to ensure safe handling. DMDC is hydrophobic and solidifies at 17°C(63°F) and the dosing machines are engineered to prevent solidification and aid in solubility. Dosers also include specific safety features and a special metering system. Scott Laboratories sells and supports Velcorin dosing machines. There are also several mobile providers who provide on-site Velcorin dosing.


The VELCORIN® DT Motion is a dosing machine that can be easily installed into new or existing filling lines, only minor modifications are necessary. Key features include:

  • High quality and robust dosing pump with monitorable dosing

  • Temperature-controlled stainless steel upper and lower cabinets containing 6 kg and 25 kg bottles

  • Control and visualization via touch panel PC
