On October 15, 2017, then Governor Jerry Brown signed the California Cleaning Product Right to Know Act of 2017 (SB 258) into law, making California the first state to require complete ingredient disclosure for cleaning products.  The California law will take effect January 1, 2020, for full disclosure on websites and on January 1, 2021, for disclosure on product labels.  One of the requirements for the employer is to make “readily printable” ingredient information available to employees in the same manner as SDSs.
