Cosmetic Science Talk
Every body in California knows about Prop 65.
Does Prop 65 allow for minimums or should a product not have any of the prop 65 item(s).
How do you really know if something like an emulsifier has any prop 65 items?
Here's the highlights from what I found on a CA gov site
"Proposition 65 requires businesses to notify Californians about significant amounts of chemicals in the products they purchase, in their homes or workplaces, or that are released into the environment"
"OEHHA has developed safe harbor levels. A business has "safe harbor" from Proposition 65 warning requirements or discharge prohibitions if exposure to a chemical occurs at or below these levels. These safe harbor levels consist of No Significant Risk Levels for chemicals listed as causing cancer and Maximum Allowable Dose Levels for chemicals listed as causing birth defects or other reproductive harm. OEHHA has established over 300 safe harbor levels to date and continues to develop more levels for listed chemicals"
I would highly suggest reading
site for the full details.
The SDS for the material would have a listing of all chemicals included, though it might not mention chemicals used in processing or exact amounts.
I'm no attorney
but it seems to be an all-or-nothing list
it doesn't seem to allow for tiny ppm or ppb amounts like even drinking water does.
Large corporations set some % of revenue aside in case they unknowingly break some regs (even if just for ppm or ppb amounts) and get sued.
Cost of doing business in Cali, they say.
