Who invented washing powder?

The invention of washing powder is attributed to several individuals and companies who made significant contributions to the development of laundry detergents. Here are a few key contributors in the history of washing powder:

1. James Boyce: In 1837, James Boyce, an American soap manufacturer, created a powdered soap product called "The Great Washing Powder." This can be considered one of the earliest versions of washing powder.

2. William Hough Watson: In the 1870s, British chemist William Hough Watson developed a process to create a soap powder that could be easily dissolved in water. He patented his invention in 1884.

3. Otto Rohm: In 1907, German chemist Otto Rohm developed a powdered detergent called "Persil." It was the first commercially available self-acting laundry detergent. Persil was a breakthrough product, as it contained enzymes that helped to remove stains more effectively than traditional soaps.
