• Solubility: Soluble in oils and organic solvents; practically insoluble in water

• Storage: Store in tightly sealed containers in a cool, dry place, protected from light and moisture

Overview
Polyglyceryl-10 decaoleate is a non-ionic fully esterified surfactant produced by the complete esterification of all available hydroxyl groups of polyglycerin-10 with ten molecules of oleic acid. This complete substitution results in a compound with maximum lipophilicity, minimal water solubility, and exceptional interfacial tension reduction in non-polar systems. It is mild, biocompatible, and biodegradable, derived from renewable plant-based sources.

Key Properties

• Non-ionic – compatible with a wide range of lipophilic ingredients and pH levels.

• Maximally lipophilic – ideal for water-in-oil (W/O) emulsions and oil-rich systems.

• Water-repellent – provides hydrophobic barrier properties.

• Excellent interfacial tension reduction – stabilizes W/O emulsions.

• Good skin compatibility and mildness – suitable for topical applications.

• Biocompatible and low toxicity – safe for external use.

• Biodegradable and derived from renewable plant-based sources.

• Provides stable, water-resistant films and textures.

Applications

• Cosmetics and personal care: Used as a primary or co-emulsifier in W/O creams, lotions, sunscreens, waterproof makeup, and hair care products. Provides water resistance, stable textures, and enhanced spreadability.

• Pharmaceuticals: Employed as a lipophilic emulsifier and penetration enhancer in topical ointments, creams, and transdermal delivery systems.

• Food industry: Used as a food emulsifier (E475) in water-in-oil systems such as margarines, spreads, and sauces.

• Industrial: Applied as a dispersant, lubricant, and water-repellent agent in specialty coatings and formulations.

Key Benefits

• Effective W/O emulsification with excellent stability.

• Maximally lipophilic – provides superior oil compatibility.

• Water-repellent – ideal for waterproof and long-wear products.

• Mild and non-irritating – suitable for sensitive skin.

• Biocompatible, biodegradable, and of natural origin.

• Compatible with a wide range of lipophilic ingredients.

• Provides stable, water-resistant films with good spreadability.

Recommended Use
Typical usage levels range from 1–5% of the formulation, depending on the desired emulsion stability, viscosity, and water resistance. For optimal performance, dissolve in the oil phase at elevated temperatures (60–70°C) before emulsification. Can be combined with co-emulsifiers and thickeners for tailored rheology.

Safety and Handling

• Generally recognized as safe (GRAS) for use in food and cosmetics at recommended concentrations.

• Low irritation potential; well-tolerated by skin.

• Avoid contact with strong oxidizers and acids.

• Store in a cool, dry place, away from direct sunlight.

• Use appropriate personal protective equipment (gloves, safety goggles) when handling.

Quality Assurance
Each batch is tested for acid value, saponification value, and emulsification performance to ensure consistent quality.
