Title: **Anatoly E Chalykh: Innovator in Hydrogel Compositions**
Introduction
Anatoly E Chalykh, based in Moscow, Russia, is a distinguished inventor recognized for his contributions to the field of hydrogel compositions. With a total of eight patents to his name, Chalykh has developed innovative solutions that serve various applications, particularly in medical fields such as wound dressings.
Latest Patents
Chalykh's latest patents focus on the development of hydrogel compositions that can be formulated in multiple ways:
1. Compositions that feature a continuous hydrophobic phase alongside a discontinuous hydrophilic phase.
2. Compositions that consist of a discontinuous hydrophilic phase and a continuous hydrophilic phase.
3. Compositions that are exclusively composed of a continuous hydrophilic phase.
These compositions are designed to be versatile, incorporating a hydrophobic polymer, specifically pressure-sensitive adhesives, plasticizing elastomers, tackifying resins, and optional antioxidants in the hydrophobic phase. The hydrophilic phases are typically formed from crosslinked hydrophilic polymers, such as sodium carboxymethylcellulose.
