Solubizing (or emulsifying) Eucaplytpus OIl and Menthol
Hi Everyone,
I am stumped. I am trying to reformulate a current bath soak that conatins 5% Eucalyptus 0.5% Menthol. It is currently solubilized by PEG 40 hydogenated castor oil; however we want to replace the PEGS I have tried many products from Seppic and Evonik with the same result; separation. It doesn’t have to be a clear system, just the ability to hold 5% Eucaplytus and 0.5% Menthol. Has anyone had a similar challenge? Any ideas much appreciated :>

I don’t think it’s going to be possible and still have it function as a bath soak.

PEGs helped enormously with that particular problem. I agree 100% with Bob.

Have you tried a glycol (e.g dipropylene glycol)/surfactant blend.
As a surfactant, possibly an amine oxide, a betaine or one of the more recent glucoside or amino acid derived surfactants.
This is only my thoughts - I’ve not tried it in practice, but 5% eucalyptus, 0.5% menthol, 60% dipropylene glycol, the remainder made up with the surfactant.

Hi Guys,
Thanks very much for your thoughts and suggestions. I wanted to stay clear of DPG /surfactant bucause it’s a banned solvent in this company; interesting though. I finally got Polysorbate 20 to hold those amounts and it looks good. Not my first choice, but it works. Thanks. -
I don’t understand. If you require to replace PEGs why are you happy with polysorbate 20?

We have made similar systems using combination of Ultrez 10 and xanthan gum in a 70:30 ratio and omitted eo adducts such as polysorbate 20.
