Is there a way of thickening undecane and tridecane?

Could silicon dioxide be used or fumed silica or something else? No water is used in the formula. Majority of it is cetiol ultimate and the rest of the formula is perfume and an eater.

     I have ultimate and aerosil 200 (silica). I eyeballed and ended up  with ~ 4% silica and it made a pretty stiff gel so I'd say yes it will work fine!
  • @EVchem. Great! I only aim to make it about as thick as sunflower oil so I imagine I would use between 0.1-0.5% of aerosil 200. I’m curious if there are any alternatives without contributing an oily feeling.
