Jessica Alba had a 'calling' to be a business owner

Los Angeles - Jessica Alba says running her business is a "life calling".

The Sin City: A Dame to Kill For actress - who has daughters Honor, six, and Haven, three with husband Cash Warren - loves bother her acting work and her eco-friendly company, The Honest Company, but says they both require very different skills.

She said: "Having a company that's making the world a better place is a life calling. Performing has also been a life calling, but they're so different."

"It takes a completely different side of my brain to do one versus the other. But I'm truly very proud of The Honest Company."

The 33-year-old beauty was inspired to start up The Honest Company - a range of household, health care, and beauty products - after experiencing an allergic reaction during her second pregnancy.

She explained to Glam Belleza Latina magazine: "I had an allergic reaction to baby laundry detergent when I was pregnant, which made me wonder: If a baby laundry detergent gives me a horrible reaction, then what will it do to a newborn? I realised that so many toxic chemicals are used in everyday products."

She added: "It's so important to empower people with as much education as possible. To me, we're successful when we can give people the information, and then they can make wise decisions from that knowledge."
