Menthyl lactate is a high-performance cooling agent synthesized to deliver an exceptional cooling experience across various applications. It serves as a modern alternative to traditional menthol, optimizing sensory properties in personal care, foods, and pharmaceutical formulations.
Compared to traditional menthol, menthyl lactate provides a longer-lasting cooling effect, eliminating the sudden, short-lived, intense irritation. Instead, it provides a gentle, lingering cooling sensation. In oral care products, it provides a long-lasting, refreshing cooling sensation after brushing; in skincare, it provides a cooling and comfortable feeling on the skin for hours.
It causes virtually no irritation to the skin or oral mucosa, making products containing menthyl lactate safe for people with sensitive skin or children. For example, when added to children's toothpaste, it prevents irritation and prevents brushing resistance.
It is compatible with a variety of raw materials. Whether in complex food formulations or diverse daily chemical product systems, it maintains its cooling properties stably and exhibits no adverse reactions with other ingredients, ensuring product quality and stability.
It is primarily produced through an esterification reaction between lactic acid and menthol using an acidic catalyst such as p-toluenesulfonic acid. During the reaction, the carboxyl groups (-COOH) of lactic acid and the hydroxyl groups (-OH) of menthol undergo dehydration condensation to produce menthyl lactate and water. The production process strictly controls key factors such as temperature, reaction time, and reactant ratio to ensure a high-purity, high-quality product, ensuring consistent quality and performance from batch to batch.
Menthyl lactate is widely used as a flavoring in various foods. In mint-flavored candies, it not only imparts a refreshing taste but also enhances the mint flavor. In chewing gum, it helps maintain a long-lasting fresh breath. Added to beverages, it imparts a unique, refreshing sensation, enriching the taste and enhancing the consumer experience.
Menthyl lactate can be added to oral care products such as toothpaste and mouthwash to create a refreshing cooling sensation when brushing and rinsing, effectively cleansing the mouth and improving breath. In skincare products such as lipstick, face cream, and sunscreen, it imparts a cooling and comfortable sensation upon application, making it particularly suitable for summer or oily skin. Adding it to shower gels provides a refreshing and enjoyable bath, leaving skin feeling refreshed and non-sticky afterward.
Menthyl lactate is commonly used in topical ointments and patches. Its cooling properties provide quick relief from skin discomfort, such as itching, pain, and burning caused by insect bites, minor burns, and sunburn, providing a cooling, anti-itching, and soothing effect.
Before use, it is recommended to test on a small area to observe any adverse reactions. Depending on the application and product requirements, the appropriate dosage should be used. Generally, an addition of 30-100 mg/kg is sufficient for a good cooling effect.
Store in a cool, dry, well-ventilated warehouse away from fire, heat sources, and direct sunlight. During use, avoid direct contact with eyes and skin. If contact occurs, rinse immediately with plenty of water and seek medical attention.
A1: Unlike traditional menthol, which can cause sudden, short-lived, and intense irritation, menthyl lactate offers a milder, gentler, and significantly longer-lasting cooling sensation.
A2: Yes. Menthyl lactate is safe for children and individuals with sensitive skin because it causes virtually no irritation to the skin or oral mucosa. It is commonly used in children's toothpaste to prevent brushing resistance.
A3: Menthyl lactate exhibits excellent compatibility. It maintains its cooling performance stably and does not react adversely with other raw materials, making it highly reliable in both complex food formulations and chemical products.
A4: While the appropriate dosage depends on specific product requirements, an addition rate of 30-100 mg/kg is generally sufficient to deliver a satisfying and noticeable cooling effect.
A5: It should be stored in a cool, dry, and well-ventilated warehouse away from direct sunlight, heat, and open fire. Avoid direct contact with eyes and skin; in case of contact, flush immediately with water and contact a medical professional.
