Field notes

The homepage reports 686 products across five laundry categories, with counts grouped by brand, manufacturer, and ingredient-label terms. Its figures are based on displayed ingredient information, and the page notes that some product details come from retailer listings; it says ingredients are transcribed as shown and that individual product pages include confirmation dates. The site does not assess whether a detergent is good or its effects on skin or clothing.
