I made rinse-off Hair Conditioner with the following formula.
Coconut oil 2% (infused with Bamboo powder)
Cetyl alcohol 2%
Cocomidopropyl Betaine 1%
Lavender+Tea Tree EO blend 0.5%
Geogard ECT 0.5%
water to 100%
I mixed the water, polyquat-7, D-Panthenol
And the oil, btms-50, cetyl alcohol in a separate beaker. I heated both in a water bath.
After everything had melted I stirred it well and also used immersion blender. Kept stirring it every few minutes while it cooled down.
Added the EOs and preservative when everything had cooled down.
Stored in a jar.
12 hours later isee that hair conditioner had separated.
I have made emulsions before successfully. I am not sure whether it the heat or the proportions which have created a problem.
