Description

Polyglyceryl-2 Isononanoate/Dimer Dilinoleate Copolymer is a complex polymer formed by the reaction of Polyglyceryl-2 with isononanoic acid and dimer dilinoleic acid. This compound is used in the cosmetic, pharmaceutical, and personal care industries for its emulsifying, moisturizing, and conditioning properties.

Chemical Composition and Structure

Polyglyceryl-2 Isononanoate/Dimer Dilinoleate Copolymer is composed of ester bonds formed by the reaction of Polyglyceryl-2 with isononanoic acid and dimer dilinoleic acid. The resulting structure includes a copolymer where Polyglyceryl-2 is esterified with both isononanoic acid and dimer dilinoleic acid, forming a stable copolymer.

Physical Properties

Polyglyceryl-2 Isononanoate/Dimer Dilinoleate Copolymer typically appears as a clear to slightly yellow liquid or semi-solid, depending on the specific composition and processing methods used. It has a mild, neutral aroma and is soluble in oils and organic solvents but has limited solubility in water. The compound's structure allows it to act as an effective emulsifier, moisturizer, and conditioner, enhancing the texture and stability of cosmetic formulations.

Production Process

Synthesis of Polyglyceryl-2: Glycerol is polymerized to produce Polyglyceryl-2, a polymer containing two glycerol units.
Preparation of Isononanoic Acid and Dimer Dilinoleic Acid: Isononanoic acid and dimer dilinoleic acid are obtained from natural sources or synthesized through chemical processes.
Esterification: Polyglyceryl-2 is reacted with isononanoic acid and dimer dilinoleic acid in the presence of a catalyst. The esterification process links the carboxyl groups of isononanoic acid and dimer dilinoleic acid with the hydroxyl groups of Polyglyceryl-2, forming the copolymer.
Purification: The resulting Polyglyceryl-2 Isononanoate/Dimer Dilinoleate Copolymer is purified to remove any unreacted materials and by-products, ensuring a high-quality final product.
Quality Control: Rigorous quality tests are conducted to evaluate the purity, stability, and composition of the copolymer, including chemical and microbiological analyses.

Applications

Cosmetic Products: Used in creams, lotions, and emulsions for its emulsifying and moisturizing properties, enhancing the texture and stability of the formulations.
Skin Care: Ideal for products aimed at providing moisturizing and protective benefits due to its ability to improve skin barrier function and reduce water loss.
Hair Care: Incorporated into shampoos, conditioners, and styling products for its ability to condition and moisturize the hair.
Pharmaceutical Products: Utilized in various formulations for its solubilizing and stabilizing properties, enhancing the delivery and stability of active ingredients.
Personal Care Products: Used in body washes, soaps, and other personal care items for its emulsifying and moisturizing effects.

Environmental and Safety Considerations

Polyglyceryl-2 Isononanoate/Dimer Dilinoleate Copolymer is generally considered safe for use in cosmetic, pharmaceutical, and personal care products. It is non-irritating and suitable for all skin types. Proper use within recommended concentrations is essential to ensure safety and maximize effectiveness. Efforts to source raw materials sustainably and to use environmentally friendly production methods are important to mitigate any potential environmental impact.

INCI


Binder agent. Ingredient that is used in cosmetic, food and pharmaceutical products as an anti-caking agent with the function of making the product in which it is incorporated silky, compact and homogenous. The binder, either natural such as mucilage, gums and starches or chemical, may be in the form of a powder or liquid.

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.

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.

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.
