Assessing Polymers in Rapid Screen

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

To begin, you can enter the CAS Registry Number (“CAS RN”) for your polymer, if one is available. Other identifiers such as US EPA PMN, EC Number, etc. can be useful as well. Those other identifiers can be included in correspondence with the Scivera Team, or supporting documentation. Only CASRNs should be entered into the CASRN field in SciveraLENS.

Polymer CASRNs are generic identifiers for polymers. Depending on the type of SciveraLENS subscription plan you have, you’ll be able to see the List Screen results and the generic GHS+ Hazard Assessment results for the polymer. This assessment provides an evaluation of the available scientific literature and is scored based on Scivera’s GHS+ Hazard Assessment criteria. In this situation, we do not have any additional specific information like molecular weight or residual monomer levels.

In some cases, we may not have completed a Verified GHS+ Hazard Assessment for the particular CASRN. This can occur if the chemical has not been presented to our team for assessment in the past. Each CASRN with an unverified GHS+ assessment  enters our queue for assessment by our board-certified toxicologists. You have the option to expedite the assessment and verification for a fee.

Polymers vary which results in varying molecular weight ranges, residual monomers, catalysts, etc.. In some cases, you may want a more in-depth evaluation, such as the process required for the Screened Chemistry Program, led by several global fashion brands. For an additional fee, Scivera’s team of Board-Certified Toxicologists will conduct a trade name specific polymer assessment. For these specific polymer assessments, you will need to provide additional information on the polymer including molecular weight and residual monomers, along with additional details (see our Scivera Polymer Assessment Form).

When you’re ready, please fill out our Scivera Polymer Assessment Form, save it as a PDF, and attach it to your SciveraLENS Collection.

Screened Chemistry Made Simple with Rapid Screen

Scivera supports many certifications including Screened Chemistry. Screened Chemistry is a process used by several global apparel brands (including Levi Strauss & Co, H&M, C&A, Nike, and others) to score chemical formulations for presence on various restricted substances lists and preferred substance lists as well as on critical underlying human and environmental health characteristics.

The Screened Chemistry Program marks an important milestone in chemicals management efforts by consumer product brands and their suppliers: Conventional list screening for basic regulatory compliance and restricted substance list control are no longer sufficient for best practices achievement. It is now cost-effective, practical, and highly valuable to go beyond these basic steps to understand and select better chemicals for processes and products using comprehensive human and environmental health characteristics.

Because Screened Chemistry assessments include both a list screening and hazard assessment on each chemical in a formulation, doing this work manually can be time-consuming and expensive. Fortunately, SciveraLENS Rapid Screen supports the Screened Chemistry Program and makes scoring and certification fast and cost-effective.

Screened Chemistry Scores can range from 0 to +50 for individual chemicals and formulations overall. The higher the Screened Chemistry score, the more preferred the chemistry. Scivera’s board-certified toxicologists generate chemical-level Screened Chemistry scores to help SciveraLENS Rapid Screen subscribers understand how individual ingredient selection will impact the overall Screened Chemistry score for a chemical product. This function of SciveraLENS Rapid Screen can be a very useful tool for chemical suppliers considering new formulations for Screened Chemistry brands and their factories.

SciveraLENS Rapid Screen can help simplify the Screened Chemistry process for you, making the process faster and more cost-effective than traditional assessment and certification methods.

Steps for Screened Chemistry Certification:

(1) Gather the required data and submit your request for assessment and certification

Screened Chemistry certification requires that you disclose the following:

  • All intentional ingredients (CASRN and concentration)
  • All unintentional ingredients (residuals, impurities, etc.) equal or greater to 100 ppm in final formulation
  • All unintentional ingredients (residuals, impurities, etc.) present in the final formulation at any concentration if listed on the ZDHC MRSL with concentration threshold of less than 100 ppm. 

You’ll also need to provide safety data sheets and technical data sheets for your product as well as any mixtures or sub-supplier products included in your product.

We have tools available to help you engage your suppliers of chemical mixtures used in your chemical products and provide the information needed to complete your Screened Chemistry assessment and certification. Your sub-suppliers’ chemical ingredients will be kept secure and confidential.

Complete the Screened Chemistry Submission Form. You can use your Rapid Screen subscription to enter this information as a Collection, preview your Screened Chemistry scores, and then automatically populate the submission form. You can also sign up for a free data-entry account in Rapid Screen and submit your product information using our secure web-based submission form. If needed, we have a manual version of this form available.

As a subscriber to Rapid Screen, you can save up to 70% on standard assessment fees (plus take advantage of the benefits of Rapid Screen for your chemicals management needs). We will provide quotes for our a-la-carte services as well as subscription-based services so you can choose the best option for you. Simply send us an email with the number of products you would like to certify and a list of unique CASRNs associated with those products.

(2) List Screen

Your chemicals are screened against the US EPA Safer Choice Program Safer Chemical Ingredients Lists (“SCIL”). If any of your chemicals are present on the full or half-green circle lists they will receive a score of 35*, if present on the yellow triangle list the chemical will receive a score of 20*. Each chemical will receive a positive score. Your chemicals are then screened against Screened Chemistry Priority Lists including the ZDHC MRSL, AFIRM RSL, California Proposition 65 List of Substances Known by the State of California to Cause Cancer or Reproductive Harm, the Greenpeace 11 RSL, and the US EPA SCIL – grey square lists. If the chemical is present on any of these lists the score for the overall formulation is automatically capped at 10.

(3) Hazard Assessment

For chemicals not present on the SCIL list or Screened Chemistry priority lists, a hazard assessment must be performed. Scivera’s GHS+ hazard assessments are accepted for Screened Chemistry. You can score between 10-50 points for each chemical depending on the hazard assessment*.

  • Products with scores of 35-50 are “Preferred Chemicals”
  • Products with scores of 20-34 are “Needs Improvement” products
  • Products with scores of 0-19 are classified as “Phase Out” products

(4) Review and Certification

Scivera’s team of board-certified toxicologists will review your formulation and assessment results, generate, and send you a Screened Chemistry Certificate for each product. Redacted product reports are also sent to the Brand requesting the Screened Chemistry information.

*Scivera provides individual chemical assessments as well as an overall formulation score using a weighted average of each chemical’s score.

If you plan on certifying your product for ZDHC MRSL Conformance, Nike Chemistry, or GreenScreen Certified, let us know. The list screen and hazard assessment conducted can be done once for multiple certifications – saving you time and money.
