I never claimed that the warning needs to include a specific qty.
From your own source, California Code of Regulations,
Title 27, Article 6. Clear and Reasonable Warnings, § 25601 Clear and Reasonable Warnings
>The message must clearly communicate that the chemical in question is known to the state to cause cancer, or birth defects or other reproductive harm.
The original proposition requires Clear and Reasonable Warnings:
>25249.6. Required Warning Before Exposure To Chemicals Known to Cause Cancer Or Reproductive Toxicity. No person in the course of doing business shall knowingly and intentionally expose any individual to a chemical known to the state to cause cancer or reproductive toxicity without first giving clear and reasonable warning to such individual, except as provided in Section 25249.10
Again, from your source, California Code of Regulations,
Title 27, Article 6. Clear and Reasonable Warnings, § 25603 Consumer Products Warnings
>(a) Warnings for consumer products exposures that include the methods of transmission and the warning messages as specified by this section shall be deemed to be clear and reasonable.
So, not only do you have to warn of harm from the specific chemicals you use in your consumer product, but also of those harmful chemicals that may have unintentionally ended up in your product. Further, the clear and reasonable warning you give should include specifically how that product will expose you to harmful chemicals (e.g. eating/drinking this Soylent will expose you to potentially harmful amounts of lead [don't know, we didn't test it, lol!]; or, eating/drinking this Soylent will expose you to X.Y (m/c/k)g of lead, which is known to the State of California to cause cancer or reproductive harm).
