Somebody has experience on gelling agents?
I want to make liquid paraffin Gel
I dont know what gelling agents are suitable for hydrocarbons

Would any of the gelling agents used for making "napalms" from gasoline not be suitable for use with such a hydrocarbon?

Thanks ,
I want to make transparent gel hydrocarbon
Does Aluminium Stearate or another Aluminium fatty acid make hydrocarbon transparent gel?

I dont know but to make aluminum stearate you can react steric acid with NaOH to make sodium stearate and then react it with AlCl3

Dissolving clear polystyrene (CD-covers for instance) in gasolin works well. A bit of xylene seems to improve gelling.

I'm not sure if this is helpful at all but the paint stripper that people distil dichloromethane from has a pretty wicked gel in it.

The polystyrene polymer swells in gasolin doesnt it? Is this how most gels are formed?
Here more about stearates:

Not sure what you mean by glue, but adding polystyrene to gasoline makes a blob of transparent gel that turns into a translucent, cloudy white film
when dried. It may be possible to use it as a glue, but I am not sure about its strength as an adhesive.

Oddly, I find that some slightly more polar solvents tend to make a more homogeneous solution when dissolving polystyrene. Tetrahydrofuran, or
nitrobenzene will produce a perfectly transparent homogeneous solution. Such solutions (viscous) can absolutely be used as adhesive, especially
between pieces of bulk (non-foamed) polystyrene, as it creates a very effective solvent weld.
On the other hand gasoline, or kerosene (and strangely, acetone) will produce a blob of swollen polystyrene sitting in the solvent.
IIRC toluene and xylene also produce a homogeneous, transparent solution but I don't have any handy to test it out.
Also, what exactly do you mean by "gel"? Do you simply mean a viscous solution? Or do you mean the classical definition of gel? (ie. A substantially
dilute (mostly solvent) cross-linked system which exhibits no flow in the steady state. Such cross-links need not be chemical in nature, as there are
any number of supramolecular or physically crosslinked gels.)

Just buy a can of polyester resin for 20 bucks. It will mix with wax.
They tried to have me "put to sleep" so I came back to return the favor.
Zom.

Different color horse.
You should look it up then because there is NO WAX involved. It's a mineral oil base, and co-polymers blended in to stabilize the oil.
A polyester, and wax candle smells like dog turds anyway.

From wikipedia:
Thickeners are used for thixotropic formulas to help the mixture form gel that adheres to vertical surfaces and to reduce the evaporation of the
solvents, thus prolonging the time the solvent can penetrate the paint. Cellulose-based agents, e.g., hydroxypropyl cellulose, are commonly used for
mixtures that are not extremely acidic or basic; under such conditions cellulose undergoes hydrolysis and loses effectiveness, so fumed silica is used
for these instead. Another possibility is using waxes (usually paraffin wax or polyethylene or polypropylene derivatives), or polyacrylate gels.
