Cooling Agent WS-10 – Menthoxypropanediol
CAS: 87061-04-9 – FEMA: 3784 – EINECS: 289-296-2
The liquid workhorse – long-lasting, heat-stable cooling for food, oral care and cosmetics.
Product Overview
WS-10 (Menthoxypropanediol, MOPD) is a colorless, low-viscosity liquid cooling agent with virtually no aroma and very low volatility. It acts across the entire oral mucosa and on the skin with a gentle yet persistent coolness lasting 15-30 minutes – no bitterness, no burning, no numbness. Its two hydroxyl groups give it better water compatibility than most WS coolants, and it stays fully active through continuous 200°C heat, making it ideal for baked and hot-process products. WS-10 blends synergistically with WS-3, WS-23 and menthyl lactate to build layered, longer-lasting cooling systems.
