Product Benefits
-
Sustained Cooling Sensation
Ester hydrolysis releases menthol gradually over 30-60 minutes, providing prolonged cooling without the sharp initial burst of free menthol -
Reduced Irritation Potential
Lower volatility and slower metabolism mean menthyl lactate is better tolerated on sensitive skin — ideal for facial and paediatric applications -
Excellent Formulation Compatibility
Soluble in most cosmetic oils, esters, and emulsifier systems. Compatible with aqueous gels, O/W emulsions, and anhydrous bases -
Non-Volatile at Skin Temperature
Remains stable in open formulations — no evaporative loss during storage or application — ensures consistent cooling throughout product life -
Masking Capability
Effectively masks bitter or unpleasant tastes in oral formulations while contributing a clean, mild minty note -
Regulatory Clearance
FEMA GRAS (no. 3748) and IFRA-approved for flavour and fragrance use. Widely accepted in global cosmetic and pharmaceutical regulations
Manufacturing Process
Raw Material Charging
High-purity L-Menthol (99%+) and Lactic Acid (88% food grade) are charged to a glass-lined reactor in stoichiometric ratio, with a slight excess of lactic acid to drive the reaction
Esterification Reaction
The mixture is heated to 100-120°C under reduced pressure (200-400 mbar) with continuous removal of water of reaction. A Dean-Stark trap collects the condensate
Catalysis & Completion
A food-grade acid catalyst (typically Amberlyst 15 ion-exchange resin) may be used to accelerate the reaction. Progress is monitored by measuring acid value and GC conversion
Catalyst Removal
If heterogeneous catalyst was used, the resin is filtered out. For homogeneous catalysis, the mixture is neutralised and washed with deionised water
Vacuum Distillation
The crude ester is distilled under high vacuum (<1 mbar) at 120-140°C to remove unreacted menthol and lactic acid. The pure menthyl lactate fraction is collected
Polishing
The distilled product is treated with activated carbon for colour adjustment if needed, then passed through a 0.2 μm membrane filter
Quality Control
Each batch is tested for purity (GC, 97%+), ester value, acid value, optical rotation, refractive index, heavy metals, and microbiological limits
Packaging
Filled into aluminium bottles (1-25 kg), HDPE drums (25-200 kg), or stainless-steel IBCs under nitrogen blanket. Tamper-evident seals and batch documentation provided
