paraben heat tolerance
In an oral spray we make, we mix PEG-60 hydrogenated castor oil with methyl- and propylparaben and then add that to the batch. In order to speed things up in production, would it be possible to make this premix and have it sit in the hotbox (~65C) until it is ready to go into the batch? I don’t think it would be in there longer then 24 hours but I just want to be sure that it would not decrease the efficacy of the parabens in the final product.
