I have a water based solution (95% water, the rest are salts) to which I want to add a lemon fragrance. I bought "water based lemon essence", but upon putting a mere drop in about 500 mL, the solution turned from crystal clear to milky off-white.
I researched and found that lemon essence is apparently one of many essential oils (citral, citronellal, cintronellol). None of which are water-soluble. That's why the result is an emulsion, and it's not translucent. (It mixed very well and it's very stable, that's not my problem)
I was wondering then if it's possible to give lemon fragrance to a water solution without turning it into a milky emulsion.
