  • Prop 65 warning question

    Posted by Newtoformulating on February 9, 2021 at 2:22 pm
    Hello. I have formulated a product with Fixate Superhold polymer. I love this ingredient but just realized on the safety data sheet there’s the ” US California Proposition 65
    This product may contain chemical(s) known to the state of California to cause cancer and/or birth defects.” 
    This has kinda crushed me because I really like the ingredient but unsure if I should move forward with it in my product with that warning on it. How safe are these ingredients for the public with this warning label. If I do move forward and use it will I have to put that same cancer warning on my actual hair product? Also, if its unsafe to use any recommendations on an ingredient that is an equal to this ingredient. Thanks so much!

    I would request a prop 65 statement from the supplier.  If the chemical in it that has the prop 65 warning has any safe harbor limits, you may be able to use it without having to include a warning on your label.

    @mhart123 I contacted the supplier and there are no safe harbor limits so I would have to put a warning on the product if I decided to manufacturer it. Would you have any idea of an ingredient that is superb like the Fixate Superhold polymer. Firm but soft hold, no flakes, humidity resistant, doesn’t turn white after it is applied. I am creating an edge control/hair gel. Thanks so much!

    Have you looked at the safety of your other ingredients?

    Hi, are we talking about (INCI name) Polyacrylate-2 Crosspolymer?
    If so, I quickly checked CosIng, FDA US, TGA AU and looks like there are no limits. Therefore I don’t think you have to put any warning on the product label. :) Hope that helps.

    There is a probably a residual solvent used in the manufacturing process that is causing the prop 65 concern.

    @Newtoformulating  I don’t have much experience in that type of product, so not sure, sorry!

    mhart123 makes a good point.  Why not contact the supplier  (assume Lubrizol) for their perspective.
