Capsaicin is the most pungent, spicy-hot substance known to man. Pure capsaicin is the “gold-standard” for hotness. The tiniest amount produces a fiery hot product. How hot? Take a look at this Scoville scale to see the relative degrees of ‘hotness’.

Capsaicin is the substance that causes the burning feeling in the mouth or nose (any contact with mucous membranes) and it also increases secretion of gastric juice. Capsaicin comes in two forms – natural, which is made from hot peppers, and synthetic, which is produced in a laboratory. The efficacy of the two forms appears to be identical.

Aversion Technologies offers the following technical grade capsaicin powders –


Capsaicin powder with concentrations from 95% to 98%

Nonivamide power with a concentration of 95%

Choosing between natural capsaicin and synthetic capsaicin (nonivamide)

How does one decide between the natural and synthetic forms of Capsaicin? Natural capsaicin is most often used in food and pharmaceutical preparations, whereas nonivamide is most commonly used in commercial applications such as pepper sprays and animal repellents. If it is going to be used as a deterrent, then the synthetic form is the better choice, primarily because of cost. The natural product is the result of a two-stage extraction process – solvent extraction followed by super-critical fluid extraction. As a result, the natural product costs about four times as much as the synthetic form.

Capsaicin has wide usage in the medical field for relief of pain, and more recently has been shown to be effective in fighting cancers. Aversion Technologies offers technical grade capsaicin in its pure, natural form widely used in foods and pharmaceuticals.

Typical Applications


Capsaicin is an attractive alternative to the currently used toxic metal-based anti-foulants for protecting submerged surfaces such as the hulls of boats.

Pest Deterrent

Capsaicin can be used to deter many pests, such as squirrels, chipmunks and other annoying animals. Capsaicin can be used as an additive to birdseed, since birds are unaffected by capsaicin. Insects are also unaffected.

Non-lethal force

Capsaicin is the active ingredient in pepper spray. When the spray comes in contact with skin, especially eyes or mucous membranes, it is very painful.


Capsaicin is used in topical ointments and creams to relieve minor aches and pains of muscles and joints. Capsaicin is also available in large adhesive bandages that can be applied to the back. Concentrations are typically between 0.025% and 0.075%. Research suggests that capsaicin is able to kill prostate cancer cells. The studies showed tumors treated with capsaicin were about one-fifth the size of the untreated tumors. One study suggests capsaicin may be effective against lung cancer cells and researchers in Canada are testing capsaicin as a cure for diabetes.
