Water-based solvents

Definition

Water-based solvents are liquid substances primarily composed of water that are used to dissolve, extract, or transport other materials without relying on organic solvents. They are favored for their lower toxicity and environmental impact, making them a central aspect of green chemistry applications focused on reducing harmful chemical usage and promoting sustainability in manufacturing processes.
