Glyceryl Distearate: English Applications

1. Cosmetics & Personal Care

• Emulsifier in Skincare

• Used in creams, lotions, and sunscreens to stabilize oil-in-water (O/W) or water-in-oil (W/O) emulsions, preventing separation and ensuring a smooth texture.

• Enhances spreadability and reduces greasiness, improving skin feel in moisturizers and anti-aging products.

• Hair Care Formulations

• Added to shampoos, conditioners, and hair masks to improve emulsion stability, lubricate strands for easier detangling, and reduce frizz.

• Lip Products

• In lipsticks and balms, it enhances consistency, prevents oil bleeding, and provides a smooth application texture.

2. Food Industry

• Emulsifier & Stabilizer (E471)

• Approved as a food additive (E471/INS 471) to stabilize emulsions in processed foods.

• Used in baked goods (e.g., bread, cakes) to improve crumb structure, extend shelf life, and retain moisture.

• In margarine, ice cream, and whipped toppings, it prevents fat crystallization and enhances smoothness.

• Confectionery

• Added to chocolates and candies to reduce stickiness, enhance gloss, and prevent sugar bloom (white streaks from crystalization).

3. Pharmaceuticals

• Pharmaceutical Excipient

• Functions as an emulsifier, lubricant, or binder in oral tablets, topical creams, and suppositories.

• Used in controlled-release formulations to modulate drug release rates.

• Parenteral & Lipid-Based Systems

• Occasionally stabilizes emulsions in injectable lipid formulations (e.g., liposomes).

4. Plastics & Polymer Industry

• Lubricant & Release Agent

• Added to PVC, PE, and PP during manufacturing to reduce friction between polymer chains, improve melt flow, and prevent adhesion to machinery.

• Acts as an internal lubricant in plastic films/sheets, enhancing processability and surface smoothness.

5. Textiles & Leather

• Textile Finishing

• Used as a softener and anti-static agent in textile coatings, improving fabric hand feel and reducing static cling.

• Leather Processing

• Applied in tanning and conditioning agents to enhance leather flexibility and water resistance.

6. Industrial Applications

• Metalworking Fluids

• Emulsifies oil-water mixtures in cutting fluids, providing cooling and lubrication during machining.

• Paints & Coatings

• Improves pigment dispersion and prevents sedimentation in water-based paints.
