Seventh Generation has formulated all of our laundry detergents to work in High Efficiency (HE) washing machines. These products are formulated to work in both standard and HE machines using the same dosage directions. Our HE formulated laundry detergents can be used in all home washing machines and laundromats.
When you see a blue oval symbol with "HE" in the lower right front of the package you will know that it can be used in your HE machine. If the HE symbol is not on the package, it should not be used in HE machines.
Following the recommendation of the Soap and Detergent Association, it is no longer suggested that consumers adapt their existing detergents to use in HE machines. To do so could void your warranties with the machine manufacturer. So, on this basis, Seventh Generation does not recommend that you use or adapt any current products you have in your home. We suggest that you not purchase any laundry detergent to use in your HE machines unless it has the HE symbol on the front of the package.
