CA SB928

Requires manufacturers of designated consumer products (air care, automotive, cleaning, and polish/floor maintenance products) to disclose all ingredients on their website and provide the website address on product labels, effective July 1, 2011.

Ingredients must be identified by Chemical Abstract Service (CAS) number and chemical name using specified nomenclature standards (CSPA dictionary, INCI, IUPAC, or common chemical name).

Allows manufacturers to withhold ingredients classified as trade secrets, but hazardous substances and readily discoverable ingredients cannot be protected as trade secrets; trade secret protections last six years.

Requires manufacturers claiming trade secret protection to submit written justification to the Department of Toxic Substances Control, with a 30-day public disclosure notice period allowing manufacturers time to seek court injunctions.

Does not conflict with or limit the Department of Toxic Substances Control's authority to implement other chemical safety regulations that provide greater public health protection.
