Industries, including textiles and apparel, are pushing toward the use of safer chemistry in their operations and supply chains.

The ToxFMD Screened Chemistry™ Program provides a streamlined platform for chemical hazard assessment and supports claims related to safer chemicals at the formulation level, supporting safer chemical identification and informed substitution. ToxFMD® is an assessment of a chemical formulation’s full disclosure of all intentionally added ingredients (no cutoff threshold level) and residuals present at or above 0.01 percent of the formulation. The ToxFMD criteria reviews against various chemical hazard assessment methods such as the U.S. EPA Safer Chemical Ingredients List (SCIL) or Master Criteria, the GreenScreen List Translator® (GS LT) or GreenScreen® for Safer Chemicals (GS), and the ZDHC Manufacturing Restricted Substances List (MRSL, Group B, v. 1.1).

ToxFMD® was originally developed by ToxServices and the ToxFMD® mark is the property of ToxServices.

Benefits of ToxFMD®

Responsible companies want to establish chemical standards and practices that go beyond meeting regulatory minimums. Consumers and organizations are pushing for safer chemical formulations in products, forcing companies to look at the chemicals they use more closely.

The ToxFMD® Program allows companies to demonstrate compliance with supplier demands and program requirements, without necessarily having to divulge proprietary information to outside parties.

The program goes beyond a restricted substances list to assess the human and environmental hazards associated with using certain chemicals and formulations.

Why Work With NSF?

NSF International provides toxicology and risk assessment services to evaluate ingredients, materials and products against U.S. and international regulations. Our professionals have evaluated over 100,000 products, with expertise in toxicology, regulatory compliance, chemistry, biochemistry, environmental chemistry, microbiology, industrial hygiene and engineering.

NSF performs third-party testing to support over 80 NSF/ANSI certification programs in a number of industries, including textiles, apparel and electronics.

Review Process

The ToxFMD® Program promotes chemical optimization using the following steps:

  • Step 1: Application and Disclosure
    • Contact NSF for an application.
    • Provide completed application, which includes a full disclosure of all intentionally added ingredients with no cutoff threshold level and any residuals present at or above 0.01 percent of the formulation.
    • Prescreen completed and results provided.
    • Receive quote from NSF, and sign quote and contract and return to NSF.
  • Step 2: Full Supplier Disclosure
    • NSF obtains full disclosure from your supply chain for ingredients with proprietary information.
    • Suppliers are required to complete the supplier information addendum form, documenting the composition of each homogeneous material including the disclosure of all intentionally added ingredients, any residuals/impurities present at ≥ 0.01% (100 ppm) and ZDHC MRSL Group B chemicals that have reportable limits below >0.01% (100 ppm). Suppliers are also required to disclose complete polymer component information present in the formulation.
  • Step 3: Assess
    • NSF assesses the formulation against the ZDHC Manufacturing Restricted Substances List (MRSL, Group B, v. 1.1), the U.S. EPA Safer Chemical Ingredients List (SCIL) and the GreenScreen List Translator® (GS LT).
    • NSF performs a LT-1 summary assessment of any chemical identified as a LT-1 by the GS List Translator.
    • NSF performs a ToxFMD® polymer assessment of any polymer in the formulation.
    • NSF performs a GreenScreen® assessment for all remaining chemicals if they are not listed on the SCIL.
  • Step 4: Verdict
    • If determined “acceptable,” the client receives:
      1. ToxFMD® certificate
      2. Confirmation that no chemical is present at or above limits specified on the ZDHC MRSL (Group B)
      3. Potential to meet the requirements of the LEED V4 Building Product Disclosure and Optimization Credit – Material Ingredients Option 1 and Option 2
    • If the formulation is determined “not acceptable” for ToxFMD®:
      1. NSF provides opportunities for continuous improvement and chemical optimization
      2. The client can address chemicals of concern and resubmit to the ToxFMD® Program
