Soy lecithin for skin spray
Hello,
I am formulating a skin spray and need assistance in maintaining a homogeneous solution. I’m currently using soy lecithin. Ingredients are mainly Water, glycerin, castor oil, lecithin, and essential oils such as lemon grass.I know to add the lecithin to the oil phase, however the end results after the emulsion isn’t producing a spray after heating and mixing. Is there any process I need to implement to get the right rheology?Any suggestions or recommendations will be appreciated. Thank you. -

Lecithin makes gloop. Gloop doesn’t atomize well for sprays. Get rid of the lecithin, try Plan B.

Thank you chemicalmatt!! I’m currently trying different emulsifiers. Appreciate the response!

Polyglyceryl-4 laurate or Polyglyceryl-4 Laurate (and) Polyglyceryl-6
Laurate will make Sprayable emulsions. -
@Abdullah: outstanding choices there my friend. The polyglyceryl fatty acid esters (PEFA) make the best sprayable emulsions.

You’ll need a preservative.

you can use emulsifier with thixotropy effect as Crodafos CES

Thank you all! Yes, I have a preservative.
I tried Montanov 68 and L, and although it solved the separation issue, the product was not spraying evenly or as a splash. Will try your recommendations.I’m new to the forum, curious if there’s a way to turn on notification here?

I have been searching and googling, however, I can not find it. I have looked through the welcome section. Thank you!
