Common Name(s): Menthone glycerin acetal,menthone glycerin acetal,menthol equivalent cooling active,sustained trpm8 stimulator

CAS Number: N/a

DESCRIPTION

What It Does: Provides trpm8-mediated cooling sensation equivalent to menthol without menthol's oxidative instability and overpowering peppermint fragrance โ€” enabling cooling sensory effects in formulations where menthol's scent intensity or stability would be problematic.

Why It's Used: Menthone glycerin acetal separates menthol's cooling function from its overpowering peppermint fragrance โ€” the acetal form provides pure trpm8 cooling with minimal aromatic character for cooling products where menthol scent is undesirable.

How It Works: The cyclic 1,3-dioxane acetal ring of menthone glycerin acetal activates trpm8 (cold/menthol receptor) at the same binding domain as l-menthol โ€” the acetal oxygen geometry mimics the menthol hydroxyl's trpm8 active site interaction. the ring's hydrolytic stability versus menthol's aldehyde oxidation provides 5-10ร— improved formulation shelf stability.

SCIENTIFIC NOTE

Trpm8 cooling potency: menthone glycerin acetal ec50 for trpm8 activation ~50 ฮผm vs menthol ec50 ~10 ฮผm โ€” slightly less potent than menthol but the improved stability and reduced fragrance load make it preferred at equivalent functional concentrations.
