Many of the sellers of bike lubes and cleanders are more focused on the retail end user where no MSDS is required. They might not want to have an MSDS link on their sites, where it might confuse or put off consumers.
However, they do maintain MSDS files, and have them available for their dealers. When I wholesaled lubes and solvents to bike shops, we took the active approach of sending shops packets of MSDS literature with their orders on a 3 year rotating basis. Many of them probably ended up in the trash, but at least we tried.
Under Federal law, and most State laws the employer has an active responsibility to maintain an MSDS file, and shouldn't be waiting for the manufacturer to send the various sheets.
