900+ listed chemicals. Changing exposure thresholds. Complex safe harbor requirements. Aleph gives you a 95-chemical database with real OEHHA NSRL/MADL values, an exposure assessment calculator, and a label generator that produces 2018-amendment-compliant warnings with named chemicals — so you get it right the first time.
California’s Prop 65 list includes over 900 chemicals known to cause cancer or reproductive harm. Figuring out which ones apply to your product is the hard part.
Each chemical has a No Significant Risk Level (NSRL) or Maximum Allowable Dose Level (MADL). Calculating whether your product exceeds these thresholds requires specialized knowledge.
Prop 65 is enforced primarily through private lawsuits. Bounty hunters file thousands of cases each year against businesses with missing or incorrect warnings.
Aleph’s Prop 65 module includes a 95-chemical database with real OEHHA NSRL/MADL threshold values, an exposure assessment calculator, and a label generator that produces 2018-amendment-compliant short-form and long-form warnings — with named chemicals as required.
Search 95 chemicals by name or CAS number. Each entry includes real OEHHA NSRL and MADL threshold values, listing type (cancer, reproductive), and safe harbor levels for your product category.
Enter chemical concentrations and product usage parameters. Aleph calculates daily exposure against NSRL/MADL thresholds and tells you whether a warning is required — or if you qualify for a safe harbor exemption.
Generate 2018-amendment-compliant Prop 65 warning labels. Short-form warnings must name specific chemicals — Aleph handles that automatically. Both short-form and long-form options with the required triangle icon.
Aleph identifies whether your product qualifies for safe harbor exemptions based on chemical levels and product category. Every determination is documented for legal defensibility.
Short-form warnings must now name the specific chemicals causing the warning — a requirement since the 2018 amendment. Aleph auto-inserts the correct chemical names into every label.
Generate both label formats. Short-form for on-product warnings with named chemicals, long-form for packaging and point-of-sale — both with the required triangle symbol and legal text.
Products often contain multiple listed chemicals. Aleph tracks all of them per product and identifies the most restrictive threshold for labeling.
Aleph’s database covers 95 chemicals common in imported consumer products, each with real OEHHA NSRL and MADL values — not estimates, but the official safe harbor levels.
Download warning labels as print-ready files. Include them in your packaging artwork or product listing images.
Every exposure calculation, safe harbor determination, and label version is logged. Demonstrate due diligence if challenged in a Prop 65 lawsuit.
