Jessica Alba is defending the Honest Company once again.

An investigation conducted by the Wall Street Journal claims that the $1.7 billion lifestyle brand’s liquid laundry detergent allegedly contains sodium lauryl sulfate, a harsh chemical the company publicly vowed never to use in its products.  The ingredient — which Alba has called a “toxin” —  reportedly turned up in tests conducted by two labs commissioned by the WSJ. One of the labs allegedly found a “significant amount” of SLS, while the other found that the Honest detergent contained about the same concentration of the chemical as Tide.

The Honest Company website states the brand uses sodium coco sulfate instead of sodium lauryl sulfate because it is a “gentler alternative always derived from coconut.” 

In a statement to Us Weekly, Honest disputed the WSJ’s findings and called the paper’s reporting “reckless.”

“Despite providing the Wall Street Journal with substantial evidence to the contrary, they falsely claimed our laundry detergent contains Sodium Lauryl Sulfate (SLS),” the company said in a statement to Us. “To set the record straight, we use Sodium Coco Sulfate (SCS) in our brand’s laundry detergent because it is a gentler alternative that is less irritating and safer to use.

"We stand behind our laundry detergent and take very seriously the responsibility we have to our consumers to create safe and effective products," the statement added.
