French cosmetics giant L'Oreal SA said it has "zero tolerance" for forced labor in its supply chain and keeps a close eye on its mineral mica sources after a report criticized the company for failing to disclose slavery risks in its operations.

The report by CORE, a watchdog on corporate accountability, said some of the world's top brands, including L'Oreal, do not report the risks of slavery associated with mica, a sparkly mineral used in makeup.

An estimated 24.9 million people are victims of forced labor globally, and nearly one in 10 children around the world is a victim of child labor, according to the International Labour Organization.

L'Oreal said its commitment to sourcing sustainable mica in India is reported on its website and that its statement under the Modern Slavery Act should be read in conjunction with its public reporting. Child labor is more common in illegal mica mines.
