Description

Almond Oil/Polyglyceryl-10 Esters is a chemical compound obtained by the transesterification of prunus amygdalus dulcis (sweet almond) oil with polyglycerin-10. 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, almond oil/polyglyceryl-10 esters consist of a mixture of esters formed from the reaction between sweet almond oil and polyglycerin-10. this structure imparts unique moisturizing and emulsifying properties to the compound:

Polyglycerol Backbone: a polymer of glycerin that imparts hydrophilic (water-attracting) properties.
Sweet Almond Oil: a natural oil that provides 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 almond odor.
Solubility: insoluble in water, but dispersible in oils and some organic solvents.
Density: varies based on specific formulation and concentration of the esters.
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.
Transesterification: prunus amygdalus dulcis (sweet almond) oil is reacted with polyglyceryl-10 under controlled temperature and pressure conditions to form the esters.
Filtration and Purification: the resulting esters are 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: almond oil/polyglyceryl-10 esters are biodegradable, making them 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.

Surfactant - Cleansing agent. Cosmetic products used to cleanse the skin utilise the surface-active action that produces a lowering of the surface tension of the stratum corneum, facilitating the removal of dirt and impurities.
