Attack even 7 day-old stains with Tide Original HE Turbo Powder Laundry Detergent with Acti-Lift Crystals. It’s formulated with HE Turbo technology. Like regular Tide, Ultra Tide Plus A Touch of Downy contains surfactants. Surfactant molecules have two parts. One is "water loving" and the other is "water hating." The water-loving (hydrophilic) part breaks the surface tension of water. The water-hating (hydrophobic) part is attracted to oil and grease in soils, loosening and removing them from fabrics. Ultra Tide Plus A Touch of Downy is also formulated with special ingredients that provide softening benefits throughout the wash.
