BUTOXY CHITOSAN.

Valuable / FILM FORMING, HAIR CONDITIONING, VISCOSITY CONTROLLING

A modified chitosan derivative engineered to create breathable, protective films on skin surfaces while enhancing barrier function. This multifunctional polymer excels at preventing transepidermal water loss and defending against environmental aggressors through its unique cationic binding properties. Its butoxy modification improves compatibility with modern formulations while maintaining the conditioning benefits of its natural chitosan foundation.

Summary

film-forming viscosity-controlling skin-conditioning barrier-enhancing

Science

Mechanism of Action

Forms a continuous, flexible film on the stratum corneum that acts as a selective barrier, preventing moisture loss while allowing skin to breathe. Its positive charge enables binding to negatively charged skin proteins, improving conditioning effects and facilitating better deposition of co-formulated actives.
