Polyglyceryl-10 Dioleate is a chemical compound formed by the esterification of a glycerin polymer containing 10 glycerin units with oleic acid. This compound is valued for its emollient, emulsifying, and moisturizing properties, making it useful in various cosmetic and pharmaceutical applications.
CHEMICAL COMPOSITION AND STRUCTURE
Chemically, polyglyceryl-10 dioleate consists of a polyglycerol backbone with ten glycerin units esterified with oleic acid. this structure imparts unique moisturizing and emulsifying properties to the compound:
Polyglycerol Backbone: a polymer of glycerin, which imparts hydrophilic (water-attracting) properties.
Oleic Acid: a fatty acid that adds hydrophobic (water-repelling) properties, enhancing the compound’s ability to blend oil and water phases.
PHYSICAL PROPERTIES
Appearance: generally a clear to pale yellow liquid.
Odor: characteristic mild odor.
Solubility: insoluble in water, but dispersible in oils and some organic solvents.
Density: varies based on specific formulation and concentration of the ester.
Viscosity: moderate to high, depending on concentration, contributing to its thickening properties in formulations.
PRODUCTION PROCESS
Preparation of Polyglyceryl-10: glycerin is polymerized to form polyglyceryl-10.
Esterification: polyglyceryl-10 is reacted with oleic acid under controlled temperature and pressure conditions to form the ester.
Filtration and Purification: the resulting ester is filtered and purified to remove impurities and obtain a high-quality product.
Packaging and Storage: the final product is packaged and stored in a cool, dry place to maintain its properties.
APPLICATIONS
Medical: used in topical formulations for its emollient and moisturizing properties, helping to improve skin health and repair the skin barrier.
Cosmetics: commonly found in creams, lotions, emulsions, and hair care products as an emollient, emulsifier, and thickening agent. enhances the texture, spreadability, and stability of cosmetic products.
Skin Care: improves hydration and skin texture in products like moisturizers, serums, and creams.
Hair Care: provides conditioning effects and improves the spreadability of hair care formulations.
Makeup: used in foundations, lipsticks, and other color cosmetics for improved application and feel.
Industrial: utilized as a non-toxic, biodegradable emulsifier and stabilizer in various industrial formulations, including lubricants and surface treatment agents.
ENVIRONMENTAL AND SAFETY CONSIDERATIONS
Biodegradability: polyglyceryl-10 dioleate is biodegradable, making it environmentally friendly and suitable for eco-conscious formulations.
Toxicity: generally considered non-toxic and safe for use in personal care and pharmaceutical products. however, it is essential to ensure that the product is free from contaminants and complies with regulatory standards.
Allergenicity: as with all chemical and natural compounds, individual reactions of intolerance or allergy cannot be excluded.
INCI
Surfactant - Emulsifying agent. Emulsions are thermodynamically unstable and are used to soothe or soften the skin and emulsify, so they need a specific, stabilising ingredient. This ingredient forms a film, lowers the surface tension and makes two immiscible liquids miscible. A very important factor affecting the stability of the emulsion is the amount of the emulsifying agent. Emulsifiers have the property of reducing the oil/water or water/oil interfacial tension, improving the stability of the emulsion and also directly influencing the stability, sensory properties and surface tension of sunscreens by modulating the filmometric performance.
