From the manufacturer's website:
Salonpas® Jet Spray provides cool, fast relief of muscle and joint pain. The convenient spray is unique in offering you two powerful pain fighting ingredients to allow you to reach hard to reach areas of the body! Menthol provides faster onset of relief with a cooling, soothing sensation, while the methyl salicylate, and NSAID controls pain for long lasting relief (up to 8 hours of targeted relief)! Finally a pain relieving spray that is no mess with its non-drip, quick drying formula! Just point and shoot on stiff joints such as arms, hands, legs, and feet. And due to the unique combination of actives, Salonpas® Jet Spray has minor smell compared to competitive products.
