UVCB substance

from Wikipedia, the free encyclopedia

A UVCB is in chemicals legislation a chemical substance of unknown or variable composition, or a complex reaction product or a biological material. The focus is UVCB for English U Nknown or V ariable composition, C omplex reaction products or B iological materials .

They cannot be adequately identified or defined by their chemical composition for one or more of the following reasons:

  • The number of components is relatively large.
  • The composition or a significant part of it is unknown.
  • The composition varies considerably or is difficult to predict.

Therefore, the substance identification must be based on the name, the origin or the source as well as the process used for processing.

Subgroup Origin / source Procedure example
1 biological synthesis Oils, citronella, reaction products with acetone
2 chemical or mineral synthesis Formaldehyde, reaction products with diethylene glycol and phenol
3 biological Refining Pancreatic extracts, deproteinated
4th chemical or mineral Refining Extracts (petroleum), cold-acid
