Shares of Honest Co., the nappy and baby-wipe seller founded by actress Jessica Alba, soared 44 per cent in their stock market debut Wednesday, valuing the company at nearly $2.1 billion.
Alba founded Honest Co. a decade ago after using baby laundry detergents that caused her allergic reactions.
Along with detergent, the company's other first products included diapers and wipes that were sold on Honest Co.'s website. Today, the brand includes moisturisers, mascara and vitamins. While most of its sales come from its website, it also sells its products in major stores, including Target and Amazon.com.
The company promotes its products as using "clean" ingredients, but its image has taken a hit in the past due to product issues.
Honest Co. paid US$7.4 million to settle a 2015 class-action lawsuit that claimed its sunscreen was ineffective and not natural as the label said. And earlier this year, it recalled a bubble bath that may have been contaminated with infection-causing bacteria.
