Premise: Of the detergents with color-safe bleaches, I tested All and Wisk (both in powder form), setting them against Liquid Tide With Bleach Alternative, which was rated the most effective detergent overall by Consumer Reports , but which made no claims to color safety or brightening.

Hypothesis: Detergents with color-safe bleaches were found not to be effective and all brands gave the same results.
Relation: contradiction
