Description

Azelaic Acid/Polyglyceryl-3 Copolymer is a cosmetic ingredient primarily used as an emulsifying agent and skin conditioner in various skincare and cosmetic formulations. It is a copolymer produced by the equimolar mixture of polyglycerin-3 and azelaic acid. This ingredient is recognized for its ability to enhance the texture and stability of products, alongside providing skin-brightening and antimicrobial benefits.

Chemical Composition and Structure

This copolymer combines the moisturizing and emulsifying properties of polyglycerin-3 with the anti-inflammatory, antibacterial, and pigment-reducing effects of azelaic acid, a dicarboxylic acid well-known in dermatology for treating acne and rosacea. The resulting copolymer is effective in stabilizing formulations and improving skin feel, making it highly suitable for formulations aimed at improving skin clarity and texture.

Physical Properties

Azelaic Acid/Polyglyceryl-3 Copolymer typically appears as a viscous, creamy substance that is white to off-white in color. It is soluble in water and can be easily incorporated into both aqueous and anhydrous systems due to its stability and compatibility with a wide range of cosmetic ingredients.

Production Process

Synthesis: The synthesis of this copolymer involves the reaction of equimolar amounts of polyglycerin-3 and azelaic acid under controlled conditions, often facilitated by a catalyst to ensure effective bonding and copolymer formation.
Purification: After synthesis, the product undergoes purification processes to remove any unreacted materials and impurities, enhancing its purity and quality for cosmetic use.
Quality Control: Rigorous quality control measures are undertaken to test the copolymer's purity, stability, and performance in cosmetic formulations. These tests typically include assessments of molecular weight, pH balance, and emulsion stability.

Applications

Cosmetic Products: Utilized in creams, lotions, and serums, particularly those designed for acne-prone or rosacea-affected skin, where it acts as an effective emulsifier and provides additional skin care benefits.
Skin Care: It is especially beneficial in formulations targeting uneven skin tone, texture irregularities, and conditions needing antimicrobial action.
Makeup: In makeup products, it helps to improve the product's adherence to the skin and can contribute to a smoother application.

Environmental and Safety Considerations

Azelaic Acid/Polyglyceryl-3 Copolymer is considered safe for use in cosmetic products and is generally well-tolerated by the skin. It is non-irritating and suitable for sensitive skin types. As both polyglycerin-3 and azelaic acid can be derived from natural sources, this copolymer is viewed as an environmentally friendly ingredient. Appropriate usage within established safety guidelines is essential to ensure consumer safety and product effectiveness.

INCI


Hair conditioning agent. A significant number of ingredients with specific and targeted purposes may co-exist in hair shampoo formulations: cleansers, conditioners, thickeners, matting agents, sequestering agents, fragrances, preservatives, special additives. However, the indispensable ingredients are the cleansers and conditioners as they are necessary and sufficient for hair cleansing and manageability. The others act as commercial and non-essential auxiliaries such as: appearance, fragrance, colouring, etc. Hair conditioning agents have the task of increasing shine, manageability and volume, and reducing static electricity, especially after treatments such as colouring, ironing, waving, drying and brushing. They are, in practice, dispersants that may contain cationic surfactants, thickeners, emollients, polymers. The typology of hair conditioning agents includes: intensive conditioners, instant conditioners, thickening conditioners, drying conditioners. They can perform their task generally accompanied by other different ingredients.
