Cooling Agent WS-12 (CAS 68489-09-8), chemically N-(4-Cyanomethylphenyl)-p-menthane-3-carboxamide, is the long-distance runner of the WS cooling agent family. Its cooling builds gradually and then lasts dramatically longer than menthol or WS-3 — which has made WS-12 the go-to ingredient for cosmetics, lip care, skin care and premium confectionery where a lingering, comfortable coolness is the goal.

Cooling Profile & Sensory Characteristics
WS-12 has a characteristic slow onset: the cooling effect appears gradually over the first minute and then persists for a remarkably long time. The sensation is soft and comfortable rather than aggressive, with no bitterness issues at normal use levels. It is frequently blended with fast-onset agents like WS-10 or WS-3 to create a complete instant + lasting cooling experience.
