Safe for use in cosmetics, with qualifications

Trolamine salicylate is a salicylate that inhibits cyclo-oxygenase (COX) enzymes responsible for generating pro-inflammatory factors such as to induce pain and inflammation. It is thought to mediate its analgesic effect through inhibition of COX-2 enzyme, which is an induced enzyme responsible for inflammatory responses and pain in muscle and joint disorders. By inhibiting fatty acid COX enzyme, trolamine salicylate inhibits the production of prostaglandins and thromboxanes in inflammatory cells involved in generating pain and inflammation. It thereby works to temporarily reduce mild to moderate pain. In subjects with muscle soreness from exercise, administration of topical trolamine salicylate was associated with reduced duration and severity of muscule soreness compared to placebo. In subjects with osteoarthritis in hands, trolamine salicylate cream was shown to be effective in achieving temporary relief of minor pain and stiffness.

Inflammation and tissue damage in different conditions including arthritis, bursitis, joint disorder, bruises, and strains or sprains of muscle origin, induce mild to moderate pain and are associated with increase prostaglandin synthesis. This is thought to be a result of COX-2 enzyme induction. COX-2 is induced in inflammatory cells in case of cell injury, infection or activation from inflammatory cytokines such as interleukin (IL)-1 and tumor necrosis factor (TNF)-α. Upon activation, COX-2 produces prostanoid mediators of inflammation such as prostaglandins and thromboxanes. Trolamine salicylate mediates its analgesic effect by inhibiting the production of inflammatory mediators that sensitize nociceptive nerve endings and generate pain.

Following topical administration of 10% trolamine salicylate in healthy volunteers, salicylic acid could not be detected in serum indicating low systemic absorption.

Following topical administration of 10% trolamine salicylate in healthy volunteers, urinary recovery of total salicylate during the first 24 hours was 6.9 mg (p < 0.05), which is 1.4% of total dose.

Topical administration of 1 gram of 10% trolamine salicylate in abdominal rat skin resulted in an approximate extravascular volume of distribution (V/F) of 24.0 mL.
