Description

Ppg-14 Polyglyceryl-2 Ether is a chemical compound formed by the etherification of polyglycerin-2 with polypropylene glycol (PPG-14). This compound is valued for its emulsifying, moisturizing, and solubilizing properties, making it useful in various cosmetic and pharmaceutical applications.

CHEMICAL COMPOSITION AND STRUCTURE

Chemically, PPG-14 polyglyceryl-2 ether consists of a polyglycerol backbone with two glycerin units linked to a polypropylene glycol (PPG-14) chain. This combination imparts unique emulsifying and moisturizing properties to the compound:

Polyglycerol Backbone: a polymer of glycerin that imparts hydrophilic (water-attracting) properties.
Polypropylene Glycol (PPG-14): a polymer chain that adds solubilizing and hydrophobic (water-repelling) properties, enhancing the compound’s ability to blend oil and water-based ingredients.

PHYSICAL PROPERTIES

Appearance: generally a clear to pale yellow liquid.
Odor: characteristic mild odor.
Solubility: soluble in water and dispersible in oils and some organic solvents.
Density: varies depending on the specific formulation and concentration of the compound.
Viscosity: moderate, contributing to its emulsifying and solubilizing properties in formulations.

PRODUCTION PROCESS

Preparation of Polyglyceryl-2: glycerin is polymerized to form polyglyceryl-2.
Etherification: polyglyceryl-2 is reacted with PPG-14 under controlled temperature and pressure conditions to form the ether.
Filtration and Purification: the resulting product is filtered and purified to remove impurities and ensure high quality.
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 moisturizing and emulsifying properties, helping to improve skin hydration and product stability.
Cosmetics: commonly found in creams, lotions, emulsions, and hair care products as an emulsifier, moisturizer, and solubilizer. Enhances the texture, spreadability, and stability of cosmetic products.
Skin Care: improves hydration and 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 an emulsifier and solubilizer in various industrial formulations, including lubricants and surface treatment agents.

ENVIRONMENTAL AND SAFETY CONSIDERATIONS

Biodegradability: PPG-14 polyglyceryl-2 ether is generally considered 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.

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.
