             ARCH PERSONAL CARE PRODUCTS AWARDED $7 MILLION AFTER
                       FEDERAL JURY FINDS IVAR MALMSTROM
                        BREACHED NON-COMPETE AGREEMENT

SOUTH PLAINFIELD, NEW JERSEY, March 8, 2004 -- Arch Personal Care Products
announced that a jury in the U.S. District Court for the District of New
Jersey has awarded it approximately $7 million in damages after finding, among
other things, that Ivar Malmstrom, Jr., had breached his non-compete
obligations to Arch Personal Care Products. Mr. Malmstrom undertook these
obligations in connection with Arch's November 2000 purchase of the personal
care intermediates business of Brooks Industries. Mr. Malmstrom had been
co-owner and president of Brooks.

The jury found that Mr. Malmstrom had assisted in the creation of, provided
funding to, and was participating in the business activities of Active
Concepts, a company formed shortly after Arch's acquisition of the Brooks
business. The jury also found that Mr. Malmstrom violated federal trademark
law, and that he and Active Concepts had infringed on Arch's TRF(TM)
trademark.

In addition, the jury found that certain asset transfers by Mr. Malmstrom to
his wife violated New Jersey's Fraudulent Transfer Act. Judge Joel Pisano has
enjoined the Malmstroms from transferring or encumbering these assets and has
appointed a receiver to take charge of the assets.





Judge Pisano had previously found that Mr. Malmstrom's assistance to Active
Concepts constituted contempt of two Court Orders issued in July 2002 that
enjoined Mr. Malmstrom from competing against Arch Personal Care. An award of
sanctions against Mr. Malmstrom in connection with the contempt finding is
expected shortly.

Arch Personal Care also has a New Jersey state court case pending against
Active Concepts and several former Brooks' employees asserting
misappropriation of trade secrets and other claims.

Defendants have thirty days from the entry of a judgment to appeal.
