Global buyers evaluating Glycerol Monolaurate need more than a polished product page. They need consistent specifications, clear documentation, and a supplier that can explain how each batch is tested. Glycerol Monolaurate, also called monolaurin, is a glycerol ester of lauric acid used in several industries. Its performance can depend on purity, formulation, and intended application. Details matter.
Dr. Jon J. Kabara’s published research on monoglycerides and antimicrobial activity offers a useful caution: performance claims should be assessed in the context of the formulation and test conditions. This is a paraphrase of the practical lesson, not a direct quotation. Buyers can apply that principle when reviewing a certificate of analysis, product identity, assay method, and batch traceability. Ask about sample availability, packaging, minimum order quantities, and realistic lead times. A quick reply is helpful. A precise one is better.
This guide examines suppliers through a buyer’s lens: product consistency, technical support, documentation, and export readiness. It also considers whether a supplier can clarify market-specific requirements for the buyer’s intended use, without treating one approval or certificate as universally valid. Compare evidence, not promises. Even careful sourcing leaves questions; specifications may not capture every difference in handling or performance. That uncertainty deserves attention. The goal is not to name a perfect supplier, but to help global buyers ask sharper questions before committing to a Glycerol Monolaurate order.
Glycerol monolaurate is an ester made from glycerol and lauric acid. It is often called monolaurin. Commercial material commonly appears as a white powder, flakes, or a waxy solid, though appearance varies with grade and processing. It has both water-attracting and oil-attracting parts, which helps it function as an emulsifier. Small differences matter.
In food and personal-care formulations, it may help disperse oils, improve texture, or support product stability. Its antimicrobial activity is studied and used in certain applications, but performance depends on concentration, formulation, and conditions. It should not be treated as a universal preservative or a medical ingredient. Real-world testing is essential.
Buyers may encounter powders, flakes, or blended liquid forms. Each handles differently: powder can be easier to dose, while flakes may need controlled heating to disperse evenly. Ask suppliers for monoester content, carrier details, particle size, melting range, and batch documentation. Check compatibility in the actual formula, not just a sample solution. I would also compare storage guidance and test for clumping after transport; that practical step is easy to overlook. Product specifications and permitted uses can vary by market, so confirm requirements for the intended application before purchase.
| Category | Dimension | Useful Information for Global Buyers |
|---|---|---|
| Identity | Common name | Glycerol monolaurate (GML), also known as glyceryl laurate or monolaurin. |
| Identity | Chemical identifiers | CAS Registry Number: 142-18-7; molecular formula: C15H30O4; molar mass: approximately 274.40 g/mol. |
| Properties | Chemical class | A monoester of glycerol and lauric acid; commonly classified as a nonionic, lipophilic emulsifier. |
| Properties | Appearance and solubility | Depending on grade and temperature, it is typically a white to off-white solid. It has low solubility in water and is more compatible with oils and some organic or surfactant systems. |
| Properties | Functional behavior | Can act as an emulsifier and may help inhibit certain microorganisms in suitable formulations. Performance depends on concentration, product matrix, processing conditions, and the target organism. |
| Uses | Food and food processing | Used in some food applications as an emulsifier or antimicrobial ingredient where permitted. Buyers should confirm applicable food regulations and permitted use levels for the destination market. |
| Uses | Personal care and cosmetics | May be used as a formulation aid, emulsifier, or functional ingredient in selected topical products. Suitability depends on the formulation, safety assessment, and local cosmetic requirements. |
| Uses | Pharmaceutical and technical applications | May be evaluated as an excipient or functional ingredient in research and formulated products. The intended grade and regulatory status must be verified for each application and market. |
| Market forms | Powder or granules | Convenient for weighing and dry blending. Check particle size, flowability, dust handling, and whether the product is pure GML or a prepared blend. |
| Market forms | Flakes, beads, or pastilles | Solid formats that can be easier to handle in bulk. Confirm dimensions, melting behavior, packaging, and suitability for the buyer’s mixing or melting process. |
| Market forms | Liquid or molten supply | Availability depends on grade and supplier. Because GML is solid under ordinary ambient conditions, temperature-controlled handling may be needed to maintain a molten form. |
| Supplier evaluation | Specification and quality documents | Request a current technical data sheet, safety data sheet, certificate of analysis, test methods, batch traceability, and details of the grade’s intended use. Compare the actual specifications rather than relying on a generic product name. |
| Supplier evaluation | Global purchasing and logistics | Confirm origin, available pack sizes, minimum order quantity, lead time, export documentation, shipping conditions, shelf life, and storage instructions. Import requirements vary by country and intended application. |
| Buyer note | Grade and regulatory checks | Commercial specifications, purity, physical form, and regulatory status vary by producer and grade. Verify the supplier’s documentation and the rules in the destination jurisdiction before purchase or use. |
