VP/eicosene copolymer is a copolymer used in cosmetic and personal care products. It is composed of a vinylpyrrolidone (VP) monomer and eicosene, a long-chain hydrocarbon. This copolymer primarily functions as a film-forming agent and stabilizer in formulations.

Chemical Composition and Structure

VP/eicosene copolymer consists of the following main components:

Vinylpyrrolidone (VP): A monomer that contributes to film formation and stability of the formulations.
Eicosene: A long-chain hydrocarbon that enhances the texture and resilience of the copolymer.

Physical Properties

VP/eicosene copolymer exhibits the following characteristics:

Appearance: Typically appears as a white or slightly opaque powder or paste.
Aroma: Generally has a neutral scent.
Texture: Forms a smooth, flexible film on the skin or hair, providing a soft feel and improving product adherence.

Production Process

The production process for VP/eicosene copolymer involves:

Polymerization: Vinylpyrrolidone and eicosene are polymerized through a chemical reaction. This reaction involves the use of catalysts and specific temperature and pressure conditions to form the copolymer.
Purification: The resulting copolymer is purified to remove any impurities and ensure the quality of the final product.
Formulation: The VP/eicosene copolymer is incorporated into cosmetic formulations as a film-forming agent and stabilizer.
Quality Control: The final product undergoes quality control testing to ensure it meets purity and performance standards.

Applications

Medical: While not commonly used in medical applications, it may be employed in dermatological products for its film-forming properties.
Cosmetic: Primarily used in products such as hair sprays, foundations, and other cosmetics, where it acts as a film-forming agent, enhancing product durability and hold.
Other: May be used in personal care products that require effective stabilization and film formation.
Environmental and Safety Considerations

VP/eicosene copolymer is generally considered safe for use in cosmetics when used according to recommended guidelines. The production of the copolymer involves measures to minimize environmental impact. Adherence to safety and quality control standards ensures the ingredient is safe for consumer use.

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.

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.

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.
