Proposition 65 Warning

California's Proposition 65 entitles California consumers to special warnings for products that contain chemicals known to the state of California to cause cancer and birth defects or other reproductive harm if those products expose consumers to such chemicals above certain threshold levels. 

We are providing the following warning for products linked to this page:

WARNING: This product contains chemicals known to the State of California to cause cancer, or birth defects or other reproductive harm.

We at Hyke & Byke take the safety of our customers very seriously. We believe our products do not create an unreasonable health and safety risk from chemical exposure when used properly as demonstrated in each product’s use documents. There are no instances in our products that any of the over 800 chemicals listed in Prop 65 are above the registered NSRL (No Significant Risk Level - create likelihood of cancer or birth defects or other reproductive harm). This allows us to comply with California law and provide our California customers with data required by Prop 65. Additional information in plain language is available from the California Office of Environmental Health Hazard Assessment at

We apologize if the Prop 65 warning has caused any confusion as to the understanding of the health risk associated with the use of our products but rest assured the safety and satisfaction of our consumers is our main priority.

If you have any questions please contact our Customer Service Department or email us at
