📝Product Overview
DGM is a high-purity glycerol monostearate refined through molecular distillation, effectively removing free glycerol, diesters/triesters, and other impurities. The product features a light color (white to pale yellow), low odor, and excellent stability, with a purity of ≥90%.
As a non-ionic surfactant, it offers multifunctional properties including emulsification, thickening, lubrication, and anti-caking. It meets food-grade (INS 471), cosmetic-grade, and pharmaceutical-grade standards, ensuring safety and environmental friendliness.

🚀Areas of application
1️⃣Food Industry
→Dairy Products/Ice Cream: Control ice crystal growth, improve melt resistance and creamy texture
→Margarine/Shortening: Prevent oil phase separation, enhance whippability and stability
→Baked Goods: Delay starch retrogradation, extend shelf life of bread/cakes, and maintain softness
→Instant Powders (Coffee/Protein Powder): Improve dispersibility and solubility, reduce clumping
→Candy/Chocolate: Regulate fat crystallization, prevent surface frosting
2️⃣Cosmetics and personal care
→Emulsification systems: Primary emulsifier (O/W type) in creams/lotions, improving stability
→Pearlescent agents: Generating uniform pearlescent luster in shampoos/body washes
→Thickeners: Enhancing the viscosity of facial cleansers, improving paste firmness
→Skin feel modifiers: Giving products a silky texture, reducing stickiness
3️⃣Pharmaceutical Industry
→Solid Dosage Forms: Lubricant for tablets/granules (reduces tableting adhesion), aids in disintegration
→Semi-Solid Dosage Forms: Emulsifying base for creams/ointments (e.g., hydrophilic creams listed in the pharmacopoeia)
→Controlled-Release Carriers: Scaffold material for sustained-release formulations (requires use with other excipients
4️⃣PVC processing
→Rigid PVC (profiles/tubes/sheets): Reduces melt torque, increases extrusion speed, and inhibits shark skin defects. Promotes uniform plasticization and prevents localized overheating degradation
→Flexible PVC (cable compounds/films/artificial leather): Enhances demolding properties, prevents roll adhesion, and optimizes melt flowability.
→Transparent products (medical devices/bottle sheets): High compatibility, zero migration, inhibits haze formation, maintains transparency.
→High-filler formulations (calcium carbonate flooring/wood-plastic composites): Optimizes filler dispersion, coats filler particles, reduces friction heat, minimizes equipment wear.
