Title: Menthol Derivative Cooling Agent
  • Article

Symrise has introduced a menthol derivative that is said to provide intense cooling in topical applications. Frescolat X-cool (INCI: Menthyl Ethylamido Oxalate) imparts a cooling effect that is felt within the first minute of application and lasts up to 30 minutes.

According to the company, menthyl ethylamido oxalate is 82% stronger than its other cooling agent menthyl lactate. The cooling agent is gentle to the skin, compatible with mucous membranes and does not cause stinging or burning sensations. In addition, it is said to have no unpleasant odor.

The colorless, viscous liquid is easy to handle. It can be cold processable by dissolving it first in fatty acid esters, ethanol and glycols. It has heat stability up to 70°C. The product safety profile allows it to be used as an active cosmetic ingredient worldwide (except in China). The company recommends its use as a consumer-perceivable marker for efficacy.

The cooling agent is recommended at 0.2–1.0% in formulations with acidic to neutral pH such as: shaving products (pre/after shave lotion), deodorant (roll-on and spray), facial care, body care (body lotion and shower gel), hair care (shampoo, conditioner and styling), after sun care and lipstick/lip gloss.
