MALTODEXTRIN/VP COPOLYMER.

Valuable CAS 1323833-56-2 / FILM FORMING

MALTODEXTRIN/VP COPOLYMER is a versatile polymer that forms a protective, breathable film on the skin, significantly aiding in moisture retention and enhancing product texture for a silky-smooth application. It additionally functions as a crucial stabilizer within formulations, improving consistency and extending the efficacy of beneficial active ingredients on the skin.

Science

Mechanism of Action

This non-ionic copolymer functions by creating a lightweight, flexible, and breathable film upon application to the skin's surface. This barrier not only provides a protective layer but also optimizes the skin's ability to retain moisture, contributing to enhanced hydration. Furthermore, its presence improves the overall aesthetic and tactile performance of formulations, yielding a refined, silky texture. Within the product, it acts as an effective stabilizer, maintaining the homogeneity and integrity of emulsions, and is capable of prolonging the durability and functional longevity of other active ingredients.

Stability

As a non-ionic polymer, MALTODEXTRIN/VP COPOLYMER is typically provided as a 25% solids solution in water. It exhibits excellent solubility in water and hydroalcoholic solutions, tolerating up to 15% ethanol. This ingredient is also well-suited for aqueous, ethanol, and glycol-based multi-phase formulations. When utilized in carbomer gels, achieving optimal clarity requires precise pH adjustment to a range between 6.0 and 6.5, and it should be introduced only after the carbomer has been neutralized.
