Consumer products maker SC Johnson said it plans to phase out a type of phthalate, a class of industrial chemical, from its fragrance products over the next two years.

Last summer, SC Johnson — which makes brands including Windex, Glade, Raid and Ziploc — started working with its suppliers to phase out DEP, a common phthalate, from fragrances in its products.

Other phthalate compounds have been found to interfere with reproductive hormones when absorbed through the mouth or skin. A federal law, which took effect last month, has banned six types of phthalates — primarily used to soften plastics — from toys.

On its website, the U.S. Consumer Product Safety Commission notes that other unbanned phthalates — like DEP — may be used in children's toys and other products.

In a statement, SC Johnson chief executive Fisk Johnson said DEP has raised concern among consumers, although he noted that it has not been found to be unsafe.

Small amounts of DEP are used in fragrance manufacturing to help scents last longer, SC Johnson said. It is the only phthalate used in its home cleaning and air care products.

"At the end of the day, we will consider making a change if it's really important to the families that use our products," Johnson said.

Racine, Wis.-based SC Johnson also said it plans to provide ingredient information for products including Windex, Shout, and Glade.

Consumers can receive ingredient information on the web, by phone, and on product labels that will be phased in over the next two years for all air care and home cleaning products. All ingredients will be listed, including dyes, preservatives and fragrances.
