Beauty products manufacturer Cosmetic Laboratories of America has been acquired by Knowlton Development Corp. in Quebec, also a maker of cosmetic and personal care supplies.

Financial terms of the acquisition were not disclosed.

Cosmetic Labs has been in Chatsworth for nearly 50 years, serving as an early formulation developer for health, beauty and fragrance brands. It employs about 350 at its facility at 20245 Sunburst St.

In a statement, General Manager Oscar Saldarriaga said the company is excited to join the world-class Knowlton team.

“I am confident that together we will achieve our goal of cementing our position as the custom developer and manufacturer of choice on the West Coast," Saldarriaga said.

Knowlton has been in expansion mode lately with the acquisition in November of Benchmark Cosmetic Laboratories in Irvine and a merger in December with HCT Group, a packaging and logistics company in Santa Monica, both of which operate large manufacturing facilities. In February, it acquired Zobele Group, an Italian manufacturer of air fresheners and insecticide devices.

In a press release, Knowlton said its strategy is to create a West Coast hub for design, research, development and manufacturing of prestige beauty products, particularly in skincare, haircare and color cosmetics. The company has one existing Chatsworth plant, which it received in the 2016 acquisition of Thibiant International, a maker of skincare products.
