📝 Product Overview

Distilled Monoglycerides (commonly known as DMG or Glycerol Monostearate E471) is a premium, high-purity non-ionic surfactant derived from natural vegetable oils (such as palm oil) through advanced molecular distillation technology. Its CAS number is 123-94-4, and its chemical formula is primarily $C_{21}{H}_{42}{O}_4$.

As a high-efficiency emulsifier, DMG contains a monoester content of $\ge 90\mathrm{\%}$. It is globally recognized as a non-toxic, safe, and biodegradable additive. It combines excellent emulsification, dispersion, and stabilization properties, making it the industry standard for improving texture and extending shelf life in both food and industrial applications.

🚀 Application Areas

DMG is a multi-functional additive utilized across food processing, plastic manufacturing, and personal care sectors where molecular stability and surface activity are essential.

①  Bakery and Flour Products: DMG is the essential crumb softener for bread and cakes. It forms a complex with starch to prevent starch retrogradation (staling), ensuring the product remains soft and fresh for a longer duration. It also improves dough stability and air cell distribution.

② Ice Cream and Frozen Desserts: In ice cream production, DMG enhances fat dispersion and improves the stability of the emulsion. It helps achieve a higher overrun (expansion rate), prevents the formation of large ice crystals, and imparts a smooth, creamy mouthfeel with better melt resistance.

③ Confectionery and Chocolates: Used in chocolates, toffees, and chewing gum to prevent oil separation and reduce stickiness. In chocolate processing, it reduces the viscosity of the cocoa mass, making it easier to mold and preventing "fat bloom" on the surface.

④ Plastic Industry (Antistatic & Lubrication): In the production of PVC, PE, and PP, DMG acts as a highly effective internal lubricant and antistatic agent. It reduces friction during extrusion, improves flowability, and serves as an anti-fogging agent in agricultural films to maintain transparency.

⑤  Margarine and Shortenings: DMG stabilizes the water-in-oil emulsion in margarines and peanut butter. It prevents oil-water separation, controls fat crystallization, and significantly improves the spreadability and texture of the final product.

⑥ Cosmetics and Pharmaceuticals: Applied in high-end creams, lotions, and ointments as a stabilizer and thickener. Due to its natural origin and excellent skin compatibility, it provides a delicate, non-greasy feel to personal care formulations.

📦 Packaging and Storage

• Packaging: Typically supplied in 25 kg craft paper-plastic composite bags with an inner moisture-proof PE liner. Bulk packaging (super sacks/ton bags) is available upon request.
• Storage: Store in a cool, dry, and well-ventilated warehouse. Avoid direct sunlight and keep away from toxic or odorous materials.
• Shelf Life: 24 months under standard storage conditions. It is recommended to keep the bags sealed to prevent clumping due to high temperatures or pressure.
