The book is structured in three parts, progressing from fundamental concepts of detergency to rigorous wash tests comparing biodegradable and conventional detergents. These tests, which analyze cleaning performance on common stains and fabrics, use industry-standard equipment. It further analyzes their biodegradability, toxicity to aquatic life, and contribution to water pollution.
A unique aspect of the book is its focus on providing practical information to consumers, including tips on optimizing wash cycles and conserving water and energy.
