In terms of SAP, yes, our diapers do contain them. They are made from sodium polycrylate. All disposable diapers have polyester in them and other types of plastics, as that is the only way to make a disposable diaper that is effective. Our diaper has been tested for safety and third-party verified by the EWG. We third-party test for toxins and we are the only diaper brand to list all of the ingredients in our diaper.
If you are interested in a diaper that does not have any polyester in it, we do also have a cloth diaper option, that is made of unbleached, organic cotton, and this is the only material that is the 'inside' or touches your baby's skin.
