California Prop 65 Testing Services

Testing for Prop 65 listed chemicals including heavy metals, acrylamide, and phthalates for California market compliance.

California Prop 65 testing determines whether products contain chemicals listed under Proposition 65 (Safe Drinking Water and Toxic Enforcement Act) — including lead, cadmium, arsenic, mercury, acrylamide, and phthalates — at levels that require consumer warning labels for products sold in California.

California Proposition 65 (Safe Drinking Water and Toxic Enforcement Act) requires businesses to provide warnings before knowingly exposing consumers to chemicals on the Prop 65 list. Qalitex Laboratories provides targeted Prop 65 testing to determine whether your products require warnings, protecting your brand from enforcement actions and consumer litigation.

What Is Prop 65?

Prop 65 lists over 900 chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm. The law applies to any product sold in California, regardless of where it is manufactured. Non-compliance can result in private attorney general lawsuits, fines up to $2,500 per day per violation, and mandatory warning labels.

What We Test For

We test for the most commonly cited Prop 65 chemicals in supplements and personal care products: Lead (MADL: 0.5 μg/day), Cadmium (MADL: 4.1 μg/day), Mercury (MADL: 0.3 μg/day), Arsenic (inorganic, NSRL: 10 μg/day), Acrylamide, Di(2-ethylhexyl)phthalate (DEHP), and Bisphenol A (BPA).

Safe Harbor Testing

If test results show your product's exposures fall below Prop 65 MADL or NSRL thresholds, you can sell in California without a warning label. Our testing reports include exposure calculations comparing results against Prop 65 limits, providing documentation for your safe harbor defense.

"While FDA restrictions play some role in manufacturing decisions, they are not as strict as the guidelines we follow with Beia. Finding the right chemist to help formulate and scale up for mass production was critical."
