Well, a review at the Walmart site says:
"Amazing!
This is by far the best laundry detergent I jave ever used! I have a front load machine and was afraid of this being too "sudsy". so I started with 1 cup of detergent and half a cup of baking soda. we have very hard water and the baking soda helps soften the water and remove odors. which I have always had to do with any name brand detergent. I used no added fabric softeners. Added half a cup of distilled vinegar to the bleach and fabric softener dispensers to cut soap residue, soften clothes and remove any remaining body odor. Omg my sheets have never been cleaner! No chemical smell either! So I tried on my husbands greasy, sweaty, gross work clothes, but cut back to 1/2 cup of detergent and 1/2 cup of baking soda, just to see what happened. His work clothes were clean, no perfume smells and so soft. I have found my new forever detergent."
