Structural formula:
1.Product Property
GML is a white to off-white, waxy flake or powder with a faint coconut odor. It is practically insoluble in water, freely soluble in hot ethanol, ether and chloroform, and dispersible in warm oils. Its melting point lies between 56 °C and 62 °C, and it exhibits broad-spectrum antimicrobial activity against Gram-positive bacteria, fungi and enveloped viruses while remaining non-toxic and biodegradable under normal use conditions.

3.Application Scope and Usage
GML is widely applied in food processing as an emulsifier for margarine, chocolate and whipped toppings, and as a preservative in bakery and meat products. In cosmetics it functions as a co-emulsifier, moisturizer and mild bacteriostat for creams, lotions and lipsticks. Textile and leather industries use it as a lubricant and softener during fiber finishing. Typical dosage ranges from 0.1 % to 1.0 % by weight, added under gentle heating (50–60 °C) to ensure uniform dispersion.
4.Package and Storage
GML is packed in 25 kg net multi-layer kraft bags with inner PE liner, or in 200 kg net open-mouth steel drums with food-grade coating. Small lots of 1 kg or 5 kg food-grade plastic jars are available upon request. Store in tightly closed containers in a cool, dry warehouse at 15–25 °C, away from direct sunlight, heat, oxidizers and sources of ignition. Keep bags upright on pallets; avoid stacking more than two pallets high. Shelf life is 24 months under recommended conditions.
