Honest Co., co-founded by actress Jessica Alba, is denying a news report that said its laundry detergent contained an ingredient that it promised its customers it would never use.

Alba helped found Honest Co. about five years ago. It sells diapers, soap, lotion and cleaning products that it says are free of harsh chemicals.”

The Wall Street Journal, in a report posted to its website Thursday, said it tested Honest Co.'s detergent at two laboratories and found it had sodium lauryl sulfate.

Honest Co. said Friday that the detergent does not contain SLS but does contain sodium coco sulfate, an ingredient it says is a “gentler alternative.” It conducted “rigorous testing” and said the Journal is wrong and “reckless.”

The Journal says its report “is accurate, fair and meets” its standards.
