Propylene glycol (PG) is a colorless and odorless liquid chemical used for decades in a wide array of applications. A synthetic substance produced in industrial quantities, it is a relatively simple organic compound that has the chemical formula C3H8O2. The U.S. Food and Drug Administration consi...
This is demonstrated in a 1993 German study by Kappus, which compared the toxicology of the synthetic antioxidants BHA and BHT in comparison with the natural antioxidant vitamin E. Because there is no indication of genotoxicity of BHA and BHT, all published findings agree with the fact that BHA...
Synthetic glycerine is made from petroleum-based propylene. It has the same chemical composition as natural glycerine. Sometimes, synthetic glycerine can be confused with propylene glycol as both come from propylene. However, glycol has only two hydroxyl (-OH) groups compared to the three in glycer...

With the advances in computing power in the last decades, mathematical and computational approaches for analysing and modelling processes have gained substantial attraction in many biological fields (e.g. for omics, brain dynamics or synthetic biology research). Also in cryopreservation, quantitative meth...
