    Now that I have my thymol I wonder what is the effect of using more than 1 drop of 10% solution per 10g of gelatin.

    I know of another emulsion maker who uses more and the emulsion has a very strong odor, like f&f cough drops. Can it change the properties in any way?

    Thanks.

    It is in alcohol usually and the combination is a bit like extra surfactant. So, if you use too much of the thymol-alcohol mix, you may have to adjust your surfactant level to compensate.

    IDK for sure, I've always known the limitations of this, so I've never experimented, but I know the properties of the thymol solution and therefore gave the best guesstimate I could.
