What is the difference between the powders used for front and top loading washing machines?

Front loader is low suds so you don't end up with a sudsy mess - they use little water so too much suds wont wash out

Many people are mostly used to load washers or may be you can say traditional washers,because it grew up with them and believe in their reliability. Traditional top load washers last between 10-12 years, so the need to update was really only because the ole' washer finally gave up. And it is this reliability that keeps people loyal to top load washers. Front load washers are known for their energy efficiency and convenient features. Unlike the top loader, the front loader's wash basket is set horizontally, and uses gravity to pull water through clothes. And because the basket never has to fill completely with water you end up using only a third of the water a top loader uses, but your clothes get just as clean. You also use less detergent, which means more money savings and fewer chemicals.

The powders designed for front loaders foam less, and have a different composition. I don't remember the exact details but my washer manual explains that because there is much less water in a front loader, the water is dirtier. The detergent is designed to sort of hold the dirt down and not let it seep back into the clothes.

This might not be much help but there is a difference. There isn't a difference in the cleaning of them but the powders for high efficiency (front loaders) don't sud up as much. Regular powders will over sud in high efficiency washers.

H E are low sudsing.=)
