Must separate SDSs be prepared for chemical mixtures?

OSHA says that where complex mixtures have similar hazards and contents (i.e., the chemical ingredients are essentially the same but the specific composition varies from mixture to mixture), the manufacturer, importer, or employer can prepare one SDS that applies to all of the similar mixtures.

Therefore, a single SDS can be developed for the various combinations of chemicals, as long as the hazards of the various mixtures are similar. This “generic” SDS must meet all of the minimum requirements found in 1910.1200(g), including the name, address, and telephone number of the responsible party preparing or distributing the SDS who can provide additional information.
