Aerosol Weapons

The active ingredient used, Oleoresin Capsicum (OC), is a red pepper oil intended to cause coughing, a burning sensation on the skin, and watering in the eyes.

Custom Filling

Aerko can package your material concentrate or help develop an aerosol version. We use environmentally friendly hydrocarbons and zero ozone depletion propellants.

Concrete Mold Release

Touché is the choice of ornamental concrete producers using latex molds. Touché’s unique formula allows for easy release, less clean up and better mold life.

Our Story

Twenty-Five years ago a citizen’s safety group approached Aerko International to develop a self defense spray for the group’s distribution network. As development began, several specific characteristics were evident as needed features of the new unit.

Obviously the most important aspect of the product was effectiveness. Active ingredients chloracetophenone (CN) and orthochlorobenzalmalonitrile (CS) were tested.

-CN is classified as lachrymator, attacking tear ducts causing eyes to water and have a burning sensation.

-CS is classified as an irritant because as well as causing the tearing, the eyes experienced severe burning, nerve endings were stimulated, mucous membranes secrete freely, and the feeling of restricted breathing occurs.

As well as having all the more drastic effects, military tests conducted in the United States and Great Britain indicated the incapacitating amount of CS to be significantly smaller than the amount of CN required to achieve the same effect. Also, the estimated lethal level of CN is much lower than the estimated lethal level of CS thus CS is a safer irritant. CS was the obvious choice.

The product was also developed to shoot a coherent amiable stream instead of a misty spray pattern seen with most aerosols. This was not an easy task but seemed necessary in order to deliver the incapacitating amount of material to the attacker without worry of blow back to the user or missed target due to wind current.

The product was formulated to be sprayed directly on the face. The solvent carrier was chosen for its characteristics of defatting the skin and quick penetration. It also delivers an invisible dye to the skin cells of the face. The dye becomes visible under ultra violet lamps for up to 48 hours. An ultra violet dye was chosen over visual dye so the subject would not know he’s marked.

Finally the product was developed utilizing a liquefied propellant system. The liquid, after injection into the can, boils to maintain constant pressure in the can. The action occurs after every use and assures the ballistic characteristics of the product’s last shot.

Compressed gasses such as carbon dioxide or nitrogen used as propellant in other products exhibit reduced velocity and spray pattern as the units empty. This is no longer the case with our modern propellant system.
