Consumer Jonathan D. Rubin on Thursday filed the suit with San Francisco's District Court of Northern California, accusing the Fantastic Four star's company of including synthetic preservatives products it has "labeled and marketed" as all-natural, TheWrap reported.
"Honest also labels and markets the products as 'natural' on its website, on third-party marketplace websites, and in print and television advertisements," the suit claims.
Among the products cited in the suit against the Santa Monica, Calif.-based business include hand and dish soap, diapers, and cleansers the company has released. Specific chemicals named in the suit include preservatives such as Methylisothiazolinone and Phenoxyethanol, and an additive called Sodium Polycrylate.
In the suit, its line of sunscreen has been deemed "ineffective in preventing unhealthy exposure to harmful UV rays."
After other complains about the SPF 30 sunscreen in August, the wealthy Good Luck Chuck stunner's company said that the product is "safe and effective," and that the gripes were all coming from a very vocal minority.
"The number of complaints received on our own website about our Sunscreen Lotion constitute less than one half of one percent of all units actually sold at honest.com," the 34-year-old star's company said in its defense.
