Description

Polyglyceryl-3 Stearate/Isostearate/Dimer Dilinoleate Copolymer is a sophisticated cosmetic ingredient primarily used as an emulsifier, skin conditioner, and texture enhancer in a variety of skincare and makeup products. This copolymer is created by reacting Dilinoleic Acid with a mixture of isostearic and stearic acids and Polyglycerin-3. This structure endows the copolymer with properties that significantly enhance the stability, moisturizing effects, and texture of cosmetic formulations.

Chemical Composition and Structure

This copolymer integrates the nurturing benefits of Dilinoleic Acid, derived from linoleic acid-rich vegetable oils, with the emollient properties of isostearic and stearic acids. Polyglycerin-3 enhances these effects by adding excellent moisture retention and emulsifying properties. The resulting copolymer is highly effective in stabilizing oil-in-water and water-in-oil emulsions and providing a rich, non-greasy feel to the skin.

Physical Properties

Polyglyceryl-3 Stearate/Isostearate/Dimer Dilinoleate Copolymer typically presents as a viscous, semi-solid substance that is clear to slightly yellowish in color. It is soluble in oils and has limited water solubility, which makes it particularly suitable for rich, creamy cosmetic formulations.

Production Process

Copolymerization: The production involves the reaction of Dilinoleic Acid with Polyglycerin-3 and a blend of isostearic and stearic acids. This copolymerization process is carefully controlled to achieve a stable and effective polymer with desired properties.
Purification: Following synthesis, the copolymer undergoes extensive purification to remove any unreacted materials and by-products, ensuring purity and suitability for cosmetic use.
Quality Control: Rigorous testing is performed on the final product to assess its purity, stability, and efficacy in various cosmetic formulations. These tests often include evaluations of emulsion stability, viscosity, and compatibility with other cosmetic ingredients.

Applications

Cosmetic Products: Extensively used in creams, lotions, and lip balms where it acts as an effective emulsifier, 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, wearability, and moisturizing effectiveness, ensuring smooth application and comfort.

Environmental and Safety Considerations

Polyglyceryl-3 Stearate/Isostearate/Dimer Dilinoleate Copolymer 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


Skin conditioning agent. It is the mainstay of topical skin treatment as it has the function of restoring, increasing or improving skin tolerance to external factors, including melanocyte tolerance. The most important function of the conditioning agent is to prevent skin dehydration, but the subject is rather complex and involves emollients and humectants that can be added in the formulation.

Skin protectant. It creates a protective barrier on the skin to defend it from harmful substances, irritants, allergens, pathogens that can cause various inflammatory conditions. These products can also improve the natural skin barrier and in most cases more than one is needed to achieve an effective result.

Surfactant - Foam booster. It has the effect of introducing gas bubbles into the water and affects the cleaning process by helping to spread the cleanser. Since sebum has an inhibiting effect on the bubble, more foam is produced in the second shampoo.
