Description

Bis-HEMA Poly(1,4-Butanediol)-9/IPDI Copolymer is a synthetic polymer used in various cosmetic and personal care products. This ingredient is highly valued for its film-forming, conditioning, and adhesive properties, making it an important component in formulations such as nail polishes, hair care products, and long-wearing cosmetics.

Chemical Composition and Structure
Bis-HEMA Poly(1,4-Butanediol)-9/IPDI Copolymer is a copolymer consisting of Bis-HEMA (bis-hydroxyethyl methacrylate), poly(1,4-butanediol), and IPDI (isophorone diisocyanate). The specific composition includes:

Bis-HEMA: Provides excellent film-forming and adhesive properties.
Poly(1,4-Butanediol): Contributes to flexibility and durability.
IPDI (Isophorone Diisocyanate): Enhances the polymer's stability and resistance to environmental factors.
Physical Properties
Bis-HEMA Poly(1,4-Butanediol)-9/IPDI Copolymer typically appears as a clear to slightly opaque liquid or a fine powder. It is soluble in various solvents, making it versatile for incorporation into different cosmetic formulations.

Cosmetic and Personal Care Applications
Film-Forming Agent: This copolymer is widely used as a film-forming agent in cosmetics, providing a long-lasting, flexible, and durable film on the skin, nails, or hair.

Adhesive: It is commonly used in nail polishes and coatings due to its strong adhesive properties, ensuring that the product stays in place for extended periods.

Conditioning Agent: Bis-HEMA Poly(1,4-Butanediol)-9/IPDI Copolymer helps to condition the skin and hair, leaving them feeling soft and smooth.

Hair Styling Products: In hair care products, it provides hold and flexibility, making it ideal for styling products like gels, sprays, and mousses.

Long-Wearing Cosmetics: It is used in long-wearing makeup formulations such as foundations, eyeliners, and lipsticks to enhance their durability and resistance to smudging and fading.

Environmental and Safety Considerations

Bis-HEMA Poly(1,4-Butanediol)-9/IPDI Copolymer is generally considered safe for use in cosmetic and personal care products when used within recommended guidelines. It is non-irritating and suitable for most skin types. As a synthetic polymer, it is designed to be stable and effective in various formulations. Proper disposal and adherence to safety regulations are important to minimize environmental impact.



What it is used for and where
Cosmetics - INCI Functions
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.
