Basic Info
Monolaurin (CAS 142-18-7): Multi-Functional Monoester for Advanced Food, Cosmetic, and Industrial Formulations
Monolaurin (also commercially referred to as Glycerol Monolaurate or GML) is a monoester formed from lauric acid and glycerin. Recognized for its amphiphilic molecular structure, Monolaurin combines lipophilic lauric acid tails with hydrophilic glycerol heads, delivering excellent surface activity, emulsification properties, and inherent antimicrobial stabilization.
Unlike basic fatty acid esters, Monolaurin demonstrates unique antimicrobial boosting capabilities by disrupting lipid-coated micro-structures and cell membranes without inducing chemical resistance. Widely utilized across personal care, food preservation, and animal nutrition, it serves as a multifunctional ingredient that replaces synthetic preservatives while enhancing emulsion stability.

To accommodate rigorous international import specifications and simplified formulation compliance, our Monolaurin (CAS 142-18-7) is produced under internationally recognized quality management regimes:
ISO 9001:2015 & ISO 22000 / FSSC 22000: Comprehensive quality and food safety system compliance from raw material saponification/esterification to packaging.
Kosher & Halal Certified: Fully compliant with religious dietary requirements for global food and supplement exports.
REACH Compliance (EU): Registered for safe commercial distribution within the European Economic Area.
US FDA GRAS Status: Glycerol Monolaurate is recognized under US FDA regulations as a direct/indirect food additive under applicable conditions.
Documentation Suite: Full technical dossier provided per batch, including Safety Data Sheet (SDS) via GHS standards, Certificate of Analysis (COA), Non-GMO Statement, Heavy Metal Analysis, and Allergen-Free Declaration.
Product Packaging
Every batch of CAS 142-18-7 undergoes strict internal testing at our dedicated analytical testing facility before commercial dispatch to ensure consistency in performance and safety.
Monoester Content (Alpha-Monoglyceride Assay): Analyzed via Gas Chromatography (GC) or High-Performance Liquid Chromatography (HPLC) to guarantee active monoester purity meets specified limits (≥ 90%).
Free Glycerol & Free Fatty Acid Determination: Monitored via titration methods to ensure free lauric acid remains within controlled parameters, preventing unintended acidity shifts in client formulations.
Melting Point Range Analysis: Verified using automated capillary melting apparatus (typically 56°C – 60°C) to ensure batch physical uniformity and ease of thermal processing.
Acid Value & Saponification Value: Tested according to official AOAC/ASTM standards to confirm reaction completeness and chemical stoichiometry.
Trace Contaminants & Micro-Limits: Total Aerobic Microbial Count (TAMC), yeast/mold, heavy metals (Pb, As, Cd, Hg), and residual solvent levels are screened via ICP-MS and USP microbial protocols.

Q1: How does Monolaurin function as a preservative booster in cosmetics? A: Monolaurin naturally destabilizes the lipid outer membranes of Gram-positive bacteria and enveloped viruses. While it is not classified as a traditional drug or heavy preservative, its surface-active mechanism disrupts microbial cell integrity, allowing lower concentrations of primary cosmetic preservatives to achieve full system protection.
Q2: What is the difference between Monolaurin (CAS 142-18-7) and Lauric Acid? A: Lauric acid is a free saturated fatty acid, whereas Monolaurin is the monoester of lauric acid attached to a glycerol backbone. Monolaurin exhibits significantly higher surface activity, emulsification power, and membrane-disruptive efficacy compared to unesterified lauric acid.
Q3: Is Monolaurin soluble in water? A: Monolaurin has limited solubility in cold water due to its low HLB value (approx. 4.5–5.0). It is readily soluble in warm ethanol, vegetable oils, hot organic solvents, and easily disperses into warm aqueous phases when processed with co-emulsifiers.
Q4: What are the recommended storage conditions for bulk Monolaurin shipment? A: Monolaurin should be stored in sealed original packaging, kept in a cool, dry, and dark warehouse environment at temperatures below 30°C. Prolonged exposure to elevated temperatures or moisture may lead to clumping or gradual ester hydrolysis.
