Sodium lauryl sulfate was detected in Honest Co.'s liquid laundry detergent, after The Wall Street Journal commissioned two independent lab tests.
Honest is a company that sells sustainable goods that it guarantees contains fewer toxic chemicals than comparable products. In the company's Honestly Free Guarantee, SLS is listed as one of the chemicals it never uses in the formulations of its products.
A chemist told the Journal that Honest's detergent had roughly the same concentration of SLS as Procter & Gamble's Tide detergent. The Journal reported that Honest disputed the results, saying that no SLS was found in its own tests.
