Assessing Polymers in SciveraLENS

If you have a polymer in your formulation and would like to assess it in SciveraLENS, you have a couple of choices.

Polymer CAS RNs are generic identifiers for polymers. You can enter this number into SciveraLENS to view an evaluation of the available scientific literature and score based on Scivera’s GHS+ Hazard Assessment criteria. Complete Formulations for polymer-containing products vary based on the additives used for various properties and how they are processed, which results in varying molecular weight ranges, residual monomers, catalysts, etc. Sometimes, you may want a more in-depth evaluation, or one may be required. Programs like the Screened Chemistry certification program, led by several global fashion brands, require additional disclosure and evaluation for polymeric substances.

 

For each polymer, we will need 3 sets of information:

  1. The CAS Registry Number for the specific polymer
    • If no CAS RN is available, please contact our toxicology team. If you have the US EPA PMN or EC Number, please provide this information.
  2. Representation for all the CAS RNs within the polymer
  3. A completed Polymer and Alcohol Ethoxylate Data Collection Form from the supplier of the polymer (PADC form)

 

To begin the assessment process, please create a formulation for each polymer and include the CAS RNs for the polymer, each monomer, co-polymer, etc., in the polymer mixture.

If the polymer is sourced from a sub-supplier, you must use the SciveraLENS request process to gather the required information directly from the supplier. They can follow the same process outlined above.

As noted above, whoever supplies the polymer must complete the PADC form. Please make sure that you include information for each of the required fields. Blank boxes that are not filled out cannot be accepted and will slow down the assessment process. Words like “none” can be used.

If an additional assessment is needed, additional fees are required.
