(-)-Menthyl lactate
(-)-Menthyl lactate is a chemical compound derived from menthol and lactic acid. It is commonly used in the food, cosmetic, and pharmaceutical industries due to its cooling and soothing properties. Here are some key points about (-)-menthyl lactate:
Chemical Structure:
- Menthol: A cyclic monoterpene alcohol derived from mint oils, known for its cooling sensation.
- Lactic Acid: An organic acid commonly found in dairy products and produced by fermentation.
When these two compounds are esterified, they form (-)-menthyl lactate.
Properties:
- Cooling Effect: Provides a mild, long-lasting cooling sensation, making it popular in topical applications.
- Solubility: It is soluble in alcohol and oils but has limited solubility in water.
- Stability: Relatively stable under normal conditions.
Applications:
- Cosmetics and Personal Care:
- Used in skincare products like lotions, creams, and balms for its soothing and cooling effects.
- Often included in after-sun products, shaving creams, and anti-itch formulations.
- Food Industry:
- Used as a flavoring agent to impart a cooling sensation in products like chewing gum, candies, and beverages.
- Pharmaceuticals:
- Incorporated into topical analgesics and anti-inflammatory products for its cooling and soothing properties.
Safety:
- Generally recognized as safe (GRAS) for use in food and cosmetics when used in appropriate concentrations.
- Non-irritating and non-sensitizing for most users, though patch testing is recommended for sensitive individuals.
Synthesis:
(-)-Menthyl lactate is typically synthesized by the esterification of (-)-menthol with lactic acid in the presence of a catalyst.
