Nonivamide, also called pelargonic acid vanillylamide or PAVA, is an organic compound and a capsaicinoid. It is an amide of pelargonic acid (n-nonanoic acid) and vanillyl amine. It is present in chili peppers,[2] but is commonly manufactured synthetically. It is more heat-stable than capsaicin.

Nonivamide is used as a food additive to add pungency to seasonings, flavorings, and spice blends. It is also used in the confectionery industry to create a hot sensation, and in the pharmaceutical industry in some formulations as a cheaper alternative to capsaicin.

Like capsaicin, it can deter mammals (but not birds or insects) from consuming plants or seeds (e.g. squirrels and bird feeder seeds).[3] This is consistent with nonivamide's role as a TRPV1 ion channel agonist. Mammalian TRPV1 is activated by heat and capsaicin, but the avian form is insensitive to capsaicin.[4]

Nonivamide is used (under the name PAVA) as the payload in "less-lethal munitions" such as the FN Herstal's FN 303 projectiles[5] or as the active ingredient in most pepper sprays,[3] which may be used as a chemical weapon.[6] As a chemical irritant, pepper sprays have been used both as a riot control munition and also a weapon to disperse peaceful demonstrators; they have also been used in other contexts, such as military or police training exercises.[6] While irritants commonly cause only "transient lacrimation, blepharospasm, superficial pain, and disorientation," their use and misuse also presents serious risks of more severe injury and disability.[6]

Treatment[edit]

Nonivamide is not soluble in water, however water will dilute it and wash it away. One study found that milk of magnesia, baby shampoo, 2% lidocaine gel, or milk, did not demonstrate significantly better performance than water, when used on pepper spray.[7]
