olyglyceryl-2 Diisostearate/IPDI Copolymer is a complex polymer formed by the copolymerization of Polyglyceryl-2 Diisostearate with isophorone diisocyanate (IPDI). This compound is used in the cosmetic, pharmaceutical, and personal care industries for its emulsifying, moisturizing, and film-forming properties.

Chemical Composition and Structure

Polyglyceryl-2 Diisostearate/IPDI Copolymer is composed of Polyglyceryl-2 Diisostearate, a diester of diglycerol and isostearic acid, copolymerized with IPDI, an aliphatic diisocyanate. The resulting structure includes urethane linkages, providing a stable copolymer with unique functional properties.

Physical Properties

Polyglyceryl-2 Diisostearate/IPDI Copolymer typically appears as a clear to slightly yellow viscous 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 film-former, enhancing the texture and stability of cosmetic formulations.

Production Process

Synthesis of Polyglyceryl-2 Diisostearate: Glycerol is polymerized to produce Polyglyceryl-2, which is then esterified with isostearic acid to form Polyglyceryl-2 Diisostearate.
Preparation of IPDI: Isophorone diisocyanate is synthesized through the phosgenation of isophorone diamine.
Copolymerization: Polyglyceryl-2 Diisostearate is reacted with IPDI in the presence of a catalyst. The copolymerization process links the diisostearate groups with the IPDI, forming urethane linkages and creating the copolymer.
Purification: The resulting Polyglyceryl-2 Diisostearate/IPDI 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, moisturizing, and film-forming 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 form a film on the skin, improving barrier function and reducing water loss.
Hair Care: Incorporated into shampoos, conditioners, and styling products for its ability to condition and form a protective film on 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 film-forming effects.

Environmental and Safety Considerations

Polyglyceryl-2 Diisostearate/IPDI 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.

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.
