Water based serum with Guar gum is separating
I made a hair serum for greying hair with darkenyl
It has
DW 60%
Propylene glycol 5%
Poly 20 2%
Edta 0.1%
Preservative eco 0.7%Glycerin 2%
Guar gum 0.5
Darkenyl 1%
Nelumbo nucifera tincture 3%DW 24.2%
EO blend 0.5%
Poly 20 1%I mixed all the ingredients one by one and then added the Guar gum and glycerin slurry at the end. But after about 2hrs there is separation. Clear phase on top and thick non transparent phase at the bottom.
Why this might have happened? And can I resolve it now?

sounds like the guar is not being hydrated. Try premixing the guar with glycerin, add it to the water upfront, mix and heat to 60/65C (not F) till the gel has formed, cool and add the rest. See how that goes.
cheers. -
Thank you for your reply @rodb1958. I’ll try this in New batch.
Is there anything I can do now to save current batch? There are heat sensitive ingredients added. As per my internet search pH reduction can be a solution. But I’m not sure. -
@greencosmetic Lowering pH works to speed Cationig guar hydration, by dissolving the outer coating. Not sure you have the same type of coating in Guar gum, but you could try.
Now, I’ve seen so many episodes of separation when using guar gum, that I’d try using HEC or HMPC instead, if possible.

Thank you for answering @ketchito. I have regular Guar gum, it’s not cationic.
Just needed some hope that I can save this batch. But looks like it can’t be done
