Monolaurin, recognized in many industries as glyceryl monolaurate, belongs to the family of monoglycerides. Produced by combining lauric acid with glycerol, this raw material holds a reliable position in food, cosmetic, and pharmaceutical manufacturing. Many recognize this ingredient for its broad use as an emulsifier and preservative. Countless scientific studies link its value to natural antimicrobial properties, which drive its demand in health-related sectors. This colorless or white, odorless, solid compound features a molecular formula of C15H30O4 and a molar mass close to 274.4 g/mol. Typical density lands around 1.0 g/cm³, depending on temperature and physical form. Products based on monolaurin appear most often as flakes, powders, pearls, or sometimes viscous liquids. Each form serves a function, whether bulk shipment, manufacturing ease, or end-use consumer application.
Monolaurin’s physical structure sets it apart from similar compounds. Built from one lauric acid chain attached to the first carbon of a glycerol backbone, it forms a sharply defined ester linkage. This single fatty acid tail gives it both hydrophilic and hydrophobic properties. Such unique chemistry accounts for its natural surfactant function. In crystalline solid form, monolaurin appears as small, white flakes or fine powders, sometimes pressed into semi-gloss pearls. Melting point sits between 60-65°C. Solubility characteristics shift with temperature—very low in cold water, rising in warm water, ethanol, and essential oils. Viscous liquid or clear solutions result from heating or blending. Chemical stability remains high under standard storage and handling, though exposure to strong acids or bases leads to decomposition. Product labeling often lists HS Code 382499 (other chemical products, n.e.s.).
Where facts matter most, monolaurin backs up claims with hard data: strong antiviral, antibacterial, and antifungal action shown through published research. Used heavily in personal care items like creams, deodorants, and soaps, monolaurin helps suppress growth of Staphylococcus aureus, Candida albicans, and other known pathogens. In food preservation, it fares well at maintaining freshness and limiting spoilage. In nutraceuticals, monolaurin appears in supplements sometimes aimed at supporting immune responses. At industrial scale, safety concerns always surface. Safety data sheets show a high margin of safety for skin contact, accidental ingestion in low doses, and environmental persistence. Not classified as a hazardous substance under standard handling. Not listed as a carcinogen, not mutagenic. Like many raw materials, direct inhalation of powder can cause mild irritation. Long-term exposure to dust or repeated skin contact should be managed with basic personal protective equipment—gloves, masks, eye shields.
Monolaurin arrives from factories in solid, semi-solid or sometimes liquid state, packed in multi-layer bags, drums, or high-density polyethylene containers. Density of the product, whether solid or liquid, hovers near 1.0 grams per cubic centimeter but shifts a bit with temperature during storage or transit. As a raw material, monolaurin needs precise handling during blending or dissolution—in liter solutions or bulk mixing, care keeps the active ingredient consistent from batch to batch. Suppliers worldwide produce to specification, with certified purity often reaching above 90%. Common commercial samples include white crystalline powder, pearl-like beads, clear viscous liquids, or soft flakes, each chosen for their suitability in different processing steps.
Physical characteristics demand close attention. Storage away from strong sunlight, heat, and moisture keeps monolaurin in prime condition. Many processing lines use low-heat systems to dissolve or blend, as high temperatures can cause unwanted breakdown. In high-concentration applications, controlling static, dust, and particulate exposure keeps the compound from becoming a nuisance. Proper ventilation during handling, as well as regular health and safety training for workers, keeps risks low. Suppliers often test incoming and outgoing batches for both active content and trace impurities. In food and cosmetics, purity matters, as contaminants affect both safety and shelf-life. Companies using monolaurin have found that clear labeling, regular staff education, and supplier audits help control both cost and compliance.
My experience with sourcing and applying monolaurin comes down to trust and track record. I have found that products that display clear raw material information and back it up with third-party test results rarely produce surprises in the plant or the field. No one wants poorly specified chemical stock in their raw goods inventory: it adds cost, risk, and sometimes puts lives or jobs on the line. As regulations tighten on safety and traceability across the globe, upstream and downstream partners are expected to verify everything—from HS Code documentation and storage records to disposal guidelines. Transitioning monolaurin suppliers or introducing a new form (such as from pearls to flakes) requires careful planning, trial batches, and close QA oversight. Persistent problems with caking, dust control, or solubility can be handled by adjusting humidity, packaging, or by mixing with compatible carriers before final use. Manufacturers increase focus on sustainability and reducing chemical waste, so waste management and recycling have become concerns during both production and after-sale product handling.
On the logistics side, the 8-digit HS Code—382499—serves as the recognized international peg for customs clearance and cross-border audits. Chemical buyers should always confirm both the product and documentation match declared codes, as professional experience shows that mix-ups delay shipments and occasionally lead to regulatory fines. Tracking provenance—batch numbers, barcodes, shipping weight per liter or kilogram—gives a layer of security against contamination and recall events. In the past, lapses here led to serious consequences for food and cosmetics producers.
Monolaurin, a staple raw material for a broad array of industries, holds its own as both safe and adaptable. Close management of physical and chemical properties pays off during processing, blending, and final use. Recognized by clear, testable specifications—formula C15H30O4, density near 1.0 g/cm³, melting around 60°C, forms ranging from flakes to crystal powder, material safety that allows standard handling—monolaurin stands as a proven ingredient for both volume and specialty customers. Markets continue to innovate with new blends, new applications, and new safety driven protocols—so working with dependable sources and keeping a close eye on both documentation and handleability remains not just recommended, but required for anyone aiming for consistent quality.
