Mattel Inc. said Wednesday that its Barbie business will partner with cosmetics company MAC for an “adult-targeted project” that will be unveiled next spring.

The El Segundo-based company didn’t give any other details about the partnership. Mattel already sells Barbie-branded cosmetics geared toward children in Europe, Latin America and Asia, but this is the first such venture in the United States.

Last year, Mattel introduced Barbie Luxe, a line of high-end designer clothing and accessories for adult women in collaboration with designers such as Anna Sui, Judith

Leiber and Tarina Tarantino. It has a similar line in Japan, where it has Barbie boutiques.

Shares in Mattel were up 23 cents to $22.86 in early trading Wednesday.
