DIY Pepper Spray




Pepper spray is made from oil of capsicum.

The process for making it is very similar to making hash oil or many other essential oil extracts including food flavorings that are oil based.

One can make it from dried or fresh chiles.  Personally I am fond of the fresh method for reasons given below.

Using fresh chiles most recipes call for using a food processor to finely chop the chile, however this process will still  leave behind a quantity of oil in the product.  This is because the purpose of the chopping process is to rupture the plant cells of the vegetable matter to allow for easier extraction of the oil.

A better machine to use at this initial stage is a food juicer.

One extracts the juice from fresh chiles, and seperates said mixture from the pulp.

The pulp is then treated with a emulsifier.  Many recipes call for the use of alcohol as oil is somewhat soluble in alcohol (see HEET fuel additive).

For food grade use, one should only use ethyl alcohol as the emulsifier.  Basically you seep the pulped chiles in alcohol, (or a petroleum product) for a time and filter said liquid from the product.  The liquid juice can also be recombined with the alcohol extract or used on its own immediately. 

Once this filtered liquid is achieved where the oil is held in suspension of the alcohol (or petroleum) one simply evaporates off the volatile elements of the solution (water and alcohol or petroleum like white gas, butane etc) 

This process of course has fire risks so one must take appropriate precautions.

I might add that you will need apropriate personal protective gear including goggles and gloves as well as a wash station.

A good method is to use a solar oven type of box to evaporate the liquid portion, it is slower but no open flame or hot heater elements to serve as a ignition source as the flash point of the evaporating distillate is quite low making easy ignition. 

The resulting oil will have a reddish color from residual chile compounds, but will not affect the end product potency much.

Here is a graphic for commercial grade extract.

Pure capsicum can be further refined using standard lab procedures which is beyond the scope of this article.

Should one need a dispensing device for said compound, a fire extinguisher or compressed air mortar like used in special effects will serve as a adequate method to dispense the material. 

Other methods are gel capsules (provided all water is removed)
