I want to thicken an oil serum and looking for advice. The chassis is very thin and I want to add some surface tension so it doesn’t drip everywhere when I apply it. The first priority is to maintain smoothness. I’d like to keep it clear if possible.

Composition includes:
CCT
c12-15
Hemisqualane
Jojoba oil
Squalane
Some essential oils

Things I’ve tried already:
Silica dimethyl silylate 3% - turns out gritty the next day
Cetyl, not enough structuring at 3% (may need more?)
Olivem 900 - nice but has tiny clumps on cooldown
Behenyl Behenate - very hazy, also tiny clumps

Any recommendations for what to try next?
