  • Seeking Polymer Chemist for deformulation

    Posted by greglar on May 14, 2024 at 8:42 am

    I’m working with a cyanoacrylate based adhesive that I intend for application on human skin; similar to a Dermabond type wound glue. I found a foreign made glue that has excellent properties and is similar to the end product I’m hoping to produce. I’m in need of a chemist who dan deformulate it so that I can re-create it and modify it to the intended purpose.

    Please let me know if you or someone you know can reverse engineer this to come up with the formula for re-creation.

    Thank you!

    Sounds like a challenging project. You’ll need someone with access to some analytical equipment if you don’t already know the composition of the polymer. @chemicalmatt any thoughts?

    Hi Perry,

    Thanks for putting thought into this. I learned about this cool site from Mary Swaab of Color Lab Cosmetics. She speaks very highly of you!

    I currently have the substance in for component analysis to determine exact ingredients with concentrations of each of these. I should have those results in about 2 weeks. Initial indications are that it includes: cyanoacrylate, acrylic acid, toluene and a soy extract. I’m awaiting the specifics.

    I’m hoping to find someone who can use the forthcoming analysis to work up a reproducable formula.

    I appreciate your time!

    @Greglar the formulation you refer to may actually be a cross-polymer of cyanoacrylate/acrylic acid and that “soy” material could refer obliquely to the x-linker used. Essentially it is Super-Glue. This likely involves peroxide radical-initiated polymer synthesis, not simple mixing. Be advised of this if results from mixing are not favorable.

      Matt,

      I’m on the hunt for someone informed in this space. Are you open to briefly connecting? If not, maybe referring me to a person or company who might lead me the right direction?

      Thank you,

      Greg

    Thank you Matt. You’re correct that this is a super glue. It’s more flexible than most super glues, which allows it to function better on human skin. It flexes with the skin and slowly wears away instead of peeling up at the edges.

    You seem quite informed. Is this a project you’d have interest in taking on?

    I’m not a chemist but I sure enjoy this learning process!
