Scientists develop eco-friendly biodegradable detergent from plants

Scientists have developed a new biodegradable detergent made from wood and corn. This product aims to reduce environmental harm caused by traditional cleaning agents. Conventional detergents can pollute water systems and harm aquatic life by contributing to harmful algal blooms. The biodegradable detergent is part of efforts supported by China’s Key Technologies R&D Program. The team, led by researcher Pengtao Liu, created a plant-based formula using tiny wood fibers and corn protein. This new detergent works well for cleaning clothes and dishes. Unlike many eco-friendly cleaners, it rinses off easily and is also cost-effective. The detergent was tested on stained cotton fabrics and various kitchen items. Results showed that while it was slightly less effective than regular laundry powder at a lower concentration, it outperformed it at a higher concentration. Microscopic analysis confirmed that the new detergent left no residue on the fabrics, indicating it won’t cause damage. When testing the detergent on chili oil stains on plates of different materials, it matched the cleaning power of commercial dish soap at the same dilution. With a higher concentration, it was even more effective. For example, it removed 92% of stains on stainless steel, whereas commercial soap at the same strength removed 87%. This development is in line with growing public interest in environmentally friendly household products. The research findings have been published in the journal Langmuir, highlighting a potential shift toward safer cleaning alternatives.
