fragrances that change colour to the formula
I have noticed that many fragrances tend to change the colour to the formulae I have prepared. In most of the cases the colour change is not a big issue because is little. However, I am wondering if the formula can be considered safe since this change is probably due to chemical reactions and not sure what are the products of these reactions.
Thank you in advance. -

Vanillin is a good example of this, right?
Perhaps wait until the colour-change has occurred and have it safety tested thereafter?
