A mild cooling agent, the ester of menthol and lactic acid. Activates the same TRPM8 receptors but without the sharp cold and irritation of pure menthol. Used in after-shave, sensitive-skin products, and lip balms. Better tolerated than menthol with a lower sensitisation risk.
Topical application
CWeak evidence. In vitro data, open-label studies, or expert consensus.
The sensory effect is confirmed. No standalone therapeutic skin effect. CIR safety profile is better than plain menthol.
Menthyl Lactate is an ester of menthol and lactic acid. Acts like menthol but provides a softer and longer-lasting cool sensation without the sharp menthol scent. Mechanism. Activates cold TRPM8 receptors in skin nerve endings. Compared with menthol, acts slower (cumulative effect) but longer – up to 4–6 hours vs 1–2 hours for menthol (Schäfer 2004). Where applied. Deodorants, aftershaves, after-sun products, sport creams and gels, shampoos. Concentration 0.1–2%. Evidence base. Few topical clinical RCTs, the evidence rests on menthol properties and empirical use. CIR confirmed safety up to 5%. Safety. Milder than menthol – causes irritation less often, suitable for sensitive skin. Pregnancy and lactation – topically safe up to 1%. Avoid nipples during lactation.
