Jessica Alba's The Honest Company sued again for false labeling

"Honest's 'Organic' Infant Formula is not organic, as labeled," the lawsuit reads. "Instead, it has synthetic ingredients that are not allowed in organic products by federal law."

The documents allege that the formula contains 11 synthetic ingredients, including sodium selenite and taurine. Sodium selenite is described as "an extremely hazardous and toxic synthetic compound," and the documents say taurine is "a synthetic additive that has been associated with negative brain and nervous system effects in animals."

The lawsuit also says the product contains some ingredients that "have not been assessed as safe for human foods -- much less for infant formulas."

The Honest website says differently.

"Our organic infant formula is carefully modeled after breast milk, and meticulously blended using non-GMO (genetically engineered), naturally-derived, organic and other high-quality ingredients, sourced from trusted organic farms to help ensure pure, safe, and quality goodness," the product's description reads.

"Our Organic Infant Formula is cleared by the Food and Drug Administration and meets all safety and nutritional standards," The Honest Company said in a statement. "It is also certified USDA Organic by an independent third party, in strict accordance with the National Organic Program. We are confident this lawsuit will be dismissed."

"The company follows strict standards of safety and we label each ingredient that goes into every product not because we have to but because it's the right thing to do," the company also said.

Last year, The Honest Company was sued for alleged false labeling for using the word "natural" on some products. Consumers also flooded social media with pictures of sunburns, claiming the Honest Sunscreen SPF 30 was ineffective.

A more recent investigation claimed that its laundry detergent contained an ingredient the company had vowed not to use.
