Cosmetics Formulation Development

Hello about Eugenol lot 291TR1 I would like to inquire as follows: 1. Solvent used for extraction. Which one is it, such as PG or water? 2. If you want to increase the viscosity of thickener you recommend it? I tried Carbopol now but it doesn't work, thanks.

Hello Eugenol soluble in Propylene Glycol . Ka (not soluble in water) in case of wanting to thicken I don't know, in the formula there is only Eugenol alone or with other elements?
