When you see a blue oval symbol with "HE" in the lower right front of the package you will know to use it in your HE machine*. If the HE symbol is not on the package, it should not be used in HE machines. Our HE formulated laundry detergents can be used in all home washing machines and laundromats.
*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.
