WIN Detergent demonstrates sustainability through various practices. Firstly, their products are not tested on animals, and none of their ingredients, including dyes or fragrances, have been tested on animals either. This commitment is recognized with a certification from Leaping Bunny, a well-known cruelty-free certification organization. Additionally, WIN Detergent is compatible with High Efficiency (HE) washing machines, which use less water per load, thereby reducing environmental impact and saving on water bills. Moreover, all of WIN's chemicals, including fragrances and dyes, are sourced from U.S. suppliers, and the packaging materials such as bottles, caps, labels, boxes, and seals are also made in the U.S. The product is bottled in St. Louis, Missouri, and warehoused in Ohio, indicating a commitment to local sourcing and reducing transportation-related carbon emissions.
