• Appearance: Light ivory waxy solid flakes with a light odor

• HLB Value: ~7

• Solubility: Dispersible in oils and organic solvents; forms light O/W emulsions

• Origin: Plant-derived (polyglycerin from vegetable glycerol + fatty acids from rice bran oil)

• Storage: Store in sealed containers in a cool, dry, and ventilated place, away from moisture and sunlight

Overview
Polyglyceryl-3 rice branate is a non-ionic surfactant produced by the esterification of polyglycerin-3 with fatty acids derived from rice bran oil. This combination creates a molecule that is both hydrophilic (due to the polyglycerol chain) and lipophilic (due to the rice bran fatty acid chain), enabling it to function as an effective emulsifier and stabilizer in cosmetic formulations. It is valued for its natural origin, mildness, and ability to create light, velvety oil-in-water (O/W) emulsions.

Key Properties

• Emulsifying activity – forms particularly fresh and light O/W emulsions with a pleasantly velvety feel.

• Skin conditioning – safe, mild, non-irritating, and helps regulate the skin.

• Natural origin – derived from renewable plant-based sources (rice bran oil and vegetable glycerol).

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

• Biodegradable and environmentally friendly.

• Neutralized with arginine in some commercial grades for enhanced performance.

Applications

• Skin care: Creams, lotions, microemulsions, and sunscreens – provides stable, light, and velvety emulsions with good sensory quality.

• Hair care: Conditioners and styling products – improves spreadability and feel.

• Cleansing products: Gentle cleansers and body washes – enhances mildness and skin conditioning.

• Color cosmetics: Foundations and primers – improves pigment dispersion and application.

• Other: Can be used as an emulsifier and stabilizer in food and industrial applications.

Key Benefits

• Effective O/W emulsification with a light, velvety texture.

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

• Provides skin conditioning and moisturizing properties.

• Biodegradable and of natural origin – ideal for natural and organic cosmetic formulations.

• Compatible with a wide range of cosmetic ingredients.

• Neutralized with arginine in some grades, offering a unique functionalized emulsifying system.

Recommended Use
Typical usage levels range from 1–5% of the formulation, depending on the desired emulsion stability, texture, and skin feel. 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 for use in 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.
