Polyglycerol-10 Oleate (CAS 304656-76-0)

Polyglycerol-10 Oleate – Versatile Emulsifier and Solubilizer for Natural Cosmetics and Household Products

Chemical Nature
Polyglycerol-10 Oleate is the esterification product of oleic acid with polyglycerol (10 glycerol units). Its molecular structure combines a hydrophobic (fatty) tail and a hydrophilic (polyol) head, giving it strong amphiphilic properties. This makes it an effective emulsifier and solubilizer, widely used in natural cosmetics and household chemicals. The high hydroxyl functionality from the 10 glycerol units enhances hydrophilicity, while the oleic acid chain provides lipophilicity.

Physical and Chemical Properties

• Approximate Formula: [C₃H₅(OH)₃]ₙ + C₁₈H₃₄O₂ → (Polyglyceryl-10)oleate

• Appearance: Pale to yellowish free-flowing liquid

• Density: 1.05–1.10 g/cm³

• Solubility: Miscible with polar solvents; emulsifies oils

• Storage: In tightly sealed containers at +5 to +25°C

Applications

• Facial cleansers and wash-off products: Provides gentle cleansing without a tight, stripped feeling.

• Food products: Can be used as an emulsifier in margarines, dressings, and sauces (subject to regulatory compliance).

• Decorative cosmetics: Improves pigment dispersion and spreadability.

• Natural cosmetics and personal care: Suitable for sensitive skin formulations due to its low irritation profile.

Safety and Environmental Profile

• Green chemistry ingredient: Meets standards for natural cosmetic formulations.

• Low irritation index: Recommended for products targeting sensitive skin.

• Biodegradable: Good biodegradability with minimal environmental impact upon disposal.

Key Benefits

• High emulsifying and solubilizing power.

• Neutral odor and hypoallergenic properties.

• Compatible with a wide range of formulation types.

• Suitable for both personal care and food applications.

• Derived from plant-based fatty acids.

Summary: Polyglycerol-10 Oleate (probable CAS 304656-76-0) is a versatile, eco-friendly emulsifier and solubilizer for natural cosmetics, personal care, and food applications. It offers excellent emulsification, gentle cleansing, low irritation, and good biodegradability.
