Description

Polyglyceryl-3 Azelate/Isostearate/Stearate Crosspolymer is a complex polymer primarily used in the cosmetic industry as an emulsifier, stabilizer, and texture enhancer. This polymer is formed by the reaction of Polyglycerin-3 with Azelaic Acid, end-capped with a mixture of Isostearic Acid and Stearic Acid. This unique structure enhances the performance and sensory properties of various skincare and makeup formulations.

Chemical Composition and Structure

This complex polymer combines the moisturizing and conditioning benefits of Polyglycerin-3, a polymer derived from glycerol, with Azelaic Acid, known for its skin-soothing and anti-inflammatory properties. The polymer is further end-capped with Isostearic Acid and Stearic Acid, which contribute to its thickening and stabilizing capabilities. The resultant polymer is highly effective at stabilizing emulsions, providing a rich, creamy texture, and enhancing the overall feel of cosmetic products on the skin.

Physical Properties

Polyglyceryl-3 Azelate/Isostearate/Stearate Crosspolymer typically appears as a viscous, semi-solid substance that is clear to slightly yellowish in color. It is soluble in oils and has limited water solubility, making it ideal for use in both oil-in-water and water-in-oil emulsions, contributing to a rich, non-greasy feel.

Production Process

Synthesis and End-Capping: The production involves the reaction of Polyglycerin-3 with Azelaic Acid, followed by end-capping with a mixture of Isostearic Acid and Stearic Acid. This process requires precise control of reaction conditions to ensure the formation of a stable and effective polymer.
Purification: Following synthesis, the polymer undergoes extensive purification to remove any unreacted materials and by-products, ensuring its purity and suitability for cosmetic use.
Quality Control: Rigorous testing is conducted on the final product to assess its purity, stability, and performance in various cosmetic formulations. These tests often include evaluations of emulsion stability, viscosity, and compatibility with other cosmetic ingredients.

Applications

Cosmetic Products: Widely used in creams, lotions, and lip balms where it acts as an effective emulsifier and stabilizer, helping to blend and stabilize the mixture of oil and water components and improving the product's overall texture and feel.
Skin Care: Ideal for use in moisturizing and anti-aging products, providing long-lasting hydration and enhancing skin barrier function due to its rich nutritional profile.
Makeup: Employed in foundations and lipsticks to improve texture, spreadability, and wear, ensuring a smooth, durable finish.

Environmental and Safety Considerations

Polyglyceryl-3 Azelate/Isostearate/Stearate Crosspolymer is considered safe for use in cosmetic products and is generally well-tolerated by the skin. It is non-irritating and suitable for all skin types, including sensitive skin. The use of naturally derived ingredients enhances its profile as an environmentally friendly choice. Proper use within recommended concentrations is essential to ensure safety and maximize effectiveness.

INCI

In cosmetic labeling, Polyglyceryl-3 Azelate/Isostearate/Stearate Crosspolymer is listed under its INCI name, reflecting its chemical identity as a complex polymer formed by the reaction of Polyglycerin-3 with Azelaic Acid, end-capped with a mixture of Isostearic Acid and Stearic Acid, used for regulatory and commercial purposes in the cosmetics industry.


Film-forming agent. It produces, upon application, a very thin continuous film with an optimal balance of cohesion, adhesion and stickiness on skin, hair or nails to counteract or limit damage from external phenomena such as chemicals, UV rays and pollution.
