Jessica Alba has hit back at the lawsuit which claims her all-natural product line, The Honest Company, is not so honest, and that it deceives consumers by containing “synthetic ingredients”.

In a statement to PEOPLE, Alba calls the lawsuit – filed by a consumer Jonathan D. Rubin – “baseless and without merit” adding: “We strongly stand behind our products and the responsibility we have to our consumers. We are steadfast in our commitment to transparency and openness.”

Rubin has alleged in his suit that products such as Honest Hand Soap, Honest Diapers, and Honest Multi-Surface Cleaner, are misleading consumers by including “unnatural” ingredients. He also claims the Honest Sunscreen is “ineffective”.

However, the 34-year-old mother-of-two has explained to PEOPLE the mission statement behind the company, saying: “I know my children, Honor and Haven, are growing up in a safer home because of our products.”

“Seven years ago, when I was pregnant with my first daughter, I was frustrated by the lack of healthy and safe product options for me and my new family. In fact, prior to launching The Honest Company, I began lobbying Congress to require that ingredients used in everyday products are tested for safety prior to entry into the marketplace.

“I started The Honest Company to develop safe and effective products not just for my children, but for families everywhere. I am very proud that we have built this company into an industry leader focused on using natural ingredients and developing products that people love.

“We believe that consumers deserve to know what s in their products whether it s diapers for their children, cleaning products for their families or beauty products for themselves. Our formulations are made with integrity and 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.

In the legal documents obtained by PEOPLE on Thursday, Rubin is seeking at least $5 million in damages for customers.
