stabilizing w/o emulsion with internal particle load
Hi everyone,
I’m working on stabilizing an inverse phase with internal particle load and with food-grade natural-derived ingredients… a nightmare
We are working on developing some natural colorants and the particles are water-soluble but we need to use them on oily media, so my first thought was phase inversion.
I’ve tried all my known tricks: non-ionic gum to cover the pigment particles on the internal phase, 2% NaCl to stabilize, glycols to lower the water activity… As emulsifier I’m using sorbitan isostearate. And I use the ultra-turrax for emulsification. It initially emulsifies seemingly well, but after some time it sweats some oily phase. I was working with 40MCT:30water:10glycerin aprox…
Someone knows if this is actually plausible, have you worked with these kinds of systems before?
Thanks!!

Do you think you could get away with using a PEG-distearate? I have had some recent successes with this product. You may need to look for something that is in the “grey” area of the brand criteria that you can use. Tough task you have there.

Not really… Too much marketing pressure. Nonetheless, how much particle load had you successfully held? I’m really curious about the viability of this concept
