    Body mist

    Hi guys! I am trying to make an insect repellent body mist using 6% citronella oil 6% lemongrass, distilled water, isopropyl alcohol. I am now starting to read about what emulsifier should i use in order to be able to combine these and not get a sticky feel.

    Any suggestions?

    Thanks!

    @Mara use a phospho-ester surfactant, most of which are compatible with IPA and water and will not create too much foam or viscosity. A solvent friendly associative polymer such as Rapidgel EZ1 would be a slam dunk, but will not mist only stream. If you wanted to transition to a gel however that would be the ideal choice. As for the sticky-tacky sensorial issue, nothing will mitigate that, not with 12.0% terpene oils inside. It will be sticky and smelly, just deal with it.

    thank you!! do you have a specific suggestion for the surfactant? Also what do you think about using polysorbate 80 for this one?

    It looks like you want to solubilise the lipid? Not really create an emulsion?

    If so, you would need to premix your essential oils in isapropanol and after mix into water.

    One commonly used emulsifier in DIY skincare products is Polysorbate 20. It is a gentle and effective emulsifier that can help blend water soccer skills world cup and oil-based ingredients without leaving a sticky feel.
