Kato Polyclay CA Prop 65 Responsibility 

Applies only to customers and users of this product in the State of California

Kato Polyclay has recently been reformulated to eliminate phthalate plasticizers. Phthalates are listed on California's Prop 65 list of chemicals that cause reproductive harm. Although this is a debatable issue and our toxicologist Dr. Woodhall Stopford has certified our formula to be nontoxic, we have decided to eliminate phthalate plasticizers from all Kato Polyclay products as other polymer clay manufacturers already have. We are currently in a transition period as we are running out of our old formula inventory and replacing it with our new formulation product. As a customer of ours, this also is a process that you will be going through. 
 
Identifying old formula from new formula Kato Polyclay is done by differentiating batch numbers. All old formula batch numbers will start with the letters "IKPC". New formula batch numbers start with the letter "K". The following list contains some tips to assist you in identifying old and new formulas:
 
1. All 1 oz in 4 color sets and 2 oz. Kato Polyclay is the new formula.
 
2. Almost all 3 oz bars are the old formula.
 
3. Old formula 12.5 oz. bars are being replaced by new formula 12.5 oz. bars with a new celllophane wrapper designed with a printed silver artist pallet on it and can also be identified by the batch number.
 
4. Kato Clear Medium was reformulated in 2007 and can be identified by the batch number. Liquid Color is a new product and does not contain phthalate plastizers, however, black and white may currently contain small amounts due to dispersion inventory and VanAken will label accordingly.
 
5. All 1.5 oz. Kato Concentrates are the old formula. New Kato Concentrates will be packaged in 1 oz bars of 4 colors.
 
6. Kato Repel Gel has not been reformulated and has never contained phathalates
 
Compliance with Colifornia's Prop 65 requires that all customers and users of products in the state of California ONLY , be notified of the potential health hazards of materials that they have listed to be carcinogens or cause reproductive harm. This is a shared responsibility that must be passed down to the consumer. Please note, the State of California has not presently banned phthalates, Prop 65 legislation only requires that the public be informed of the potential hazards.
