Prop 65

California Proposition 65

The California Proposition 65 statute states that no person in the course of doing business shall “knowingly and intentionally expose any individual to a listed chemical” without first giving a clear and reasonable warning. The governor of California is required to publish annually a list of chemical substances that the state has determined to either cause cancer or cause birth defects or other reproductive harm.

Manufacturers and distributors of products in or to the state of California must identify and properly label the chemical substances found in their product. Examples are heavy metals like lead, fire retardants, and plasticizers such as phthalates. In addition, for products such as carpets, volatile organic compounds (VOC) emissions must be limited.

NSL Chemistry Testing Capabilities

NSL’s in-house laboratories are equipped with the latest equipment for testing chemical content specific for the Proposition 65 label and content law.

Common Testing Requests for Proposition 65:

  • Lead (Pb)
  • Mercury (Hg)
  • Cadmium (Cd)
  • Hexavalent Chromium (Cr(VI))
  • Nickel (Ni)
  • Bisphenol A (BPA)
  • Polybrominated Biphenyls (PBB)
  • Polybrominated Diphenyl Ethers (PBDE)

In addition to individual elements and testing NSL has created specific bundles.

Available California Proposition 65 Testing Bundles:

  • Prop 65 Elemental Bundle: Lead (Pb), Cadmium (Cd), and Nickel (Ni) Content, Element Analysis by ICPMS to determine detection of Pb, Cd and Ni.
  • Prop 65 Bundle: Phthalates Content Bundle, This is a Pass/Fail test to determine the content level of Phthalates (DBP, DBIP, BBP, DEHP, DIDP, DNHP/DHEXP, DCHP, DPENP, DINP).
  • Prop 65 Phthalates + Lead (Pb) Bundle.
  • Prop 65 Phthalates, Lead (Pb), Cadmium (Cd) Bundle.
  • Prop 65 BPA Content Bundle
    Total BPA (Solvent Extraction). Total BPA (content) is measured in parts per million (ppm). This tells us how much is actually in the product.
    BPA Leachable (Synthetic Perspiration). This tells us how much BPA can be extracted out.

CALIFORNIA PROPOSITION 65 NOTICE. Testing done by NSL for purposes of California’s Proposition 65 (Prop 65) requirements will be based on information and test limits currently available to the public at the time of testing. NSL testing and analysis will show the percentage of existence and/or the absence of certain compounds or elements, but NSL cannot certify compliance with Prop 65 law. NSL test results do not alleviate customer’s responsibility for Prop 65 labeling, if necessary. NSL will not make any recommendations or opinions on whether labeling is necessary.
