Seventh Generation Laundry Detergent is not sulfate free as it contains Sulfate as a cleaning agent.
Seventh Generation uses sodium lauryl sulfate (SLS) as the surfactant in their cleaning products.
Two differentiating factors are that this surfactant is 100% biobased and that it has non-detectable levels of 1,4 dioxane (a known chemical of concern).
Seventh Generation laundry detergent does have Formaldehyde.
The Seventh Generation Free & Clear detergent is marketed as both “safe & effective.”
This claim is backed up by the detergent's compliance with the U.S. EPA Safer Product Standards.
As part of this distinction, the company has provided full disclosure of their ingredients.
The Seventh Generation Principle is based on an ancient Haudenosaunee (Iroquois)* philosophy that the decisions we make today should result in a sustainable world seven generations into the future.
Seventh Generation Laundry Detergent is a good laundry detergent and it sells out pretty quickly.
Seventh Generation Laundry detergent is just as good and sometimes better than other laundry detergents.
I find that Seventh Generation Laundry Detergent is even better than Tide or other more expensive brands of laundry detergent and it gets my laundry clean.
Most laundry detergents will contain some chemicals even if they are made to be better for the environment as laundry detergents will need some chemicals to work correctly on stains and grime.
But Seventh Generation Laundry Detergent is better for the environment and better for your clothes and laundry than some other laundry detergents.
