Description

Polyglyceryl-3 Sunflowerseedate/Citrate Crosspolymer is a synthetic polymer used extensively in the cosmetic industry as an emulsifier, stabilizer, and texture enhancer. This polymer is created through the reaction of Sunflower Seed Acid with Polyglycerin-3, followed by crosslinking with citric acid. The resulting product enhances the performance and sensory properties of a wide range of skincare and makeup formulations.

Chemical Composition and Structure

This complex polymer blends the skin-conditioning properties of sunflower seed acid, rich in linoleic acid, with the hydrating and emollient benefits of Polyglycerin-3. Citric acid acts as a crosslinking agent, contributing to the stability and efficacy of the polymer by forming a network that can improve the texture and longevity of cosmetic products.

Physical Properties

Polyglyceryl-3 Sunflowerseedate/Citrate Crosspolymer typically appears as a viscous, semi-solid gel that is clear to slightly yellowish in color. It is soluble in water and compatible with a variety of cosmetic ingredients, making it particularly effective in water-based formulations where it enhances viscosity and stability.

Production Process

Synthesis and Crosslinking: The synthesis involves reacting Sunflower Seed Acid with Polyglycerin-3 to form an initial polymeric structure, which is then crosslinked with citric acid. This step is critical for achieving the desired mechanical and chemical properties of the polymer.
Purification: Following synthesis, the product undergoes extensive purification to ensure the removal of unreacted materials and impurities, achieving a high level of purity suitable for cosmetic use.
Quality Control: Rigorous testing is conducted on the final product to assess its purity, stability, and performance in various cosmetic formulations. Tests often include evaluations of rheological properties, stability under different environmental conditions, and compatibility with other cosmetic ingredients.

Applications

Cosmetic Products: Widely used in lotions, creams, and serums where it acts as an effective emulsifier and stabilizer, helping to maintain the integrity and uniformity of the product while enhancing user experience.
Skin Care: Ideal for use in hydrating and protective skincare products, providing enhanced moisture retention and improving skin barrier function.
Makeup: Employed in foundations and concealers to improve their texture, spreadability, and wear, ensuring a smooth, durable finish.

Environmental and Safety Considerations

Polyglyceryl-3 Sunflowerseedate/Citrate 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 components derived from natural sources like sunflower seed acid and citric acid enhances its profile as an environmentally friendly option. Proper use within recommended concentrations is essential to ensure safety and maximize effectiveness.

INCI


Emulsion stabiliser. Emulsions are thermodynamically unstable. Emulsion stabilisers improve the formation and stability of single and double emulsions. as well as their shelf-life. It should be noted that in the structure-function relationship, the molar mass of the ingredient used plays an important role.

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.
