Menthyl Lactate is a menthol-derived cooling ingredient used in cosmetic and personal care formulations to provide a refreshing, cooling sensation on the skin. Compared with menthol, it is generally used when a gentler cooling experience and a less pronounced minty aroma are desired.
Supplied as a white crystalline solid with a mild characteristic odor, Menthyl Lactate is suitable for skincare, body care, and hair care formulations where a fresh, cooling sensory effect is desired.

Menthyl Lactate is insoluble in water but soluble in ethanol, mineral oil, and suitable ester solvents.
For cosmetic formulations, dissolve the crystals in a compatible solvent or oil phase before incorporating into the finished product.
Gentle warming may assist dissolution. The supplier reports a typical melting range of 40–47°C.
The appropriate usage concentration depends on the desired cooling intensity, application area, and overall formulation. The supplied COA and SDS do not specify a recommended cosmetic usage percentage.
Conduct formulation compatibility, stability, and safety assessments before commercial use.
Store Menthyl Lactate in tightly closed, light-resistant containers in a cool, dry, well-ventilated area below 25°C.
Protect from direct sunlight, moisture, and excessive heat. Keep away from strong oxidizing agents, strong acids, and strong alkalis.
Avoid direct contact with eyes and prolonged contact with skin when handling the concentrated ingredient.
For professional cosmetic formulation use only. Not intended for direct application to the skin in raw, concentrated form.
