Auto Wax
Formula (w/w in grams)
Water - 70.89
Mineral Spirits - 11.50
Cetrimonium Chloride - 3.08
Siloxane - 8.50
Cetyl Alcohol - 2.67
Palm Wax - 0.50
Preservative - 0.25
Food Color Red Solution - 0.01
Fragrance - 0.60
Anti-static - 2.00
Process is:
1. Pre-heat water.
2. Melting Cetyl Alcohol in Mineral Spirits + Siloxane in a hotplate until it is fully dissolved.
3. Add Palm Wax.
4. Then add the solution from Steps 2-3 to the pre-heated water.
5. Add Cetri. Chlr.
6. Scents, colorants, preservative and anti-static.
Upon standing for a few days, I identified that Siloxane separates from the solution and the solution agglomerates. After standing it in a stability chamber at 40C/60% RH then cooling it down, after a day, it separated?
I’m trying to adjust the emulsifier: Cetyl and Cetrimonium chloride? What could you guys guide me to prevent the phase sep.?

You need to make sure that both water and oil phases are few degrees above the highest melting point of your ingredients. Also, mixing should be vigorous when you combine both pases. And I’d choose a different emulsifier (like ceteareth-20, for instance…Mineral spirits would be hard to emulsify due to its very low polarity).
