I'm starting to poke around to see if I can come up with info on that. I have found the following:
Regarding the beads in scrubs:
"These beads are too small for water treatment plants to filter out, so they end up in our waterways and eventually the ocean. In the ocean, tiny plastic pieces mix with the zooplankton to enter the food chain. Whats more, plastic in the ocean acts as a sponge, absorbing and concentrating toxic chemicals. Its one thing when plastic ends up there inadvertently, but its inexcusable for companies to produce plastic products intentionally meant to be flushed down the drain. - See more at: http://myplasticfreelife.com/2013/06/take-action-no-more-plastic-micro-beads-in-facial-scrubs/#sthash.aGACa3Ne.dpuf"
And I found this from one company re: MSDS on poly spheres used in various products:

Pending bills (from article at http://www.kelleydrye.com/publications/client_advisories/0892)
"The New York bill the Microbead-Free Waters Act was proposed by Attorney General Eric Schneiderman and Assemblyman Robert K. Sweeney and coincided with the Attorney Generals announcement of LOréals decision to discontinue the use of microbeads in its cosmetic products. The proposed law, which would take effect December 31, 2015, would prohibit the production, manufacture, sale, or offer for sale of any personal care product containing intentionally-added microbeads, defined as any plastic component of a personal cosmetic product measured to be five millimeters or less in size. The bill defines personal cosmetic product as any product intended to be applied to the human body for cleansing, beautifying, promoting attractiveness, or altering the appearance, excluding prescription drugs. Violators would be liable for a civil penalty up to $2,500 per day.
The California bill, introduced by Assemblyman Richard Bloom, would amend the Safe Drinking Water and Toxic Enforcement Act of 1986 (commonly known as Proposition 65) to prohibit the selling or offering for promotional purposes of any cleaning product or personal care product containing 1 part per million (ppm) or greater of microplastic defined as any plastic five millimeters or less in size. Cleaning products and personal care products are defined as mixtures and solutions used for bathing and cleaning, and include, but are not limited to, hand and body soap, exfoliates, shampoos, toothpastes, and scrubs. This bill would not become effective until January 1, 2016, but would also impose a civil penalty of $2,500 per day per violation. "
