PAVA spray
incapacitant spray similar to pepper spray
PAVA spray is an incapacitant spray similar to pepper spray. It is dispensed from a handheld canister, in a liquid stream. It contains a 0.3% solution of pelargonic acid vanillylamide (PAVA), also called nonivamide, a synthetic capsaicinoid (analogue of capsaicin), in a solvent of aqueous ethanol. The propellant is nitrogen. This solution has been selected because this is the minimum concentration which will fulfill the purpose of the equipment: namely, to minimise a person's capacity for resistance, without unnecessarily prolonging their discomfort.
PAVA is significantly more potent than CS gas. The liquid stream is a spray pattern and has a maximum effective range of up to four metres (13 ft). Maximum accuracy, however, will be achieved over a distance of 1.25–2 metres (4.1–6.6 ft). The operating distance is the distance between the canister and the subject's eyes, not the distance between the user and the subject.
Effects
PAVA primarily affects the eyes, causing closure and severe pain.

Why this record matters
“PAVA spray” is worth following because a concise public description often conceals a longer documentary argument. Here, PAVA, spray and incapacitant provides the most credible route into that argument.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 21, 2026. The linked authority identifier is Q7118290. None of the 0 selected statements returned an explicit reference.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
