PFAS - Toxic "Forever Chemicals"

1

New research found that many smartwatch and fitness tracker bands contain high levels of PFAS "forever chemicals." A University of Notre Dame study detected PFAS in fluoroelastomer bands at concentrations exceeding 16,000 parts per billion—far higher than typically found in consumer products. The EPA has designated certain PFAS as hazardous substances, and these chemicals persist in the environment and human body. Solace bands are made from nylon and have been independently tested PFAS-free.

BPAF

2

BPAF (Bisphenol AF) is used as a curing agent in fluoroelastomer manufacturing. It belongs to the bisphenol family (which includes BPA) and has raised similar concerns among toxicologists. The National Toxicology Program has studied BPAF's properties, and regulatory agencies continue to evaluate its use in consumer products. Solace bands contain no bisphenols—verified by independent testing.

Cyclosiloxanes

3

Cyclosiloxanes (D4, D5, D6) are silicon-based compounds that can be present in some silicone products as manufacturing byproducts or processing aids. The European Chemicals Agency (ECHA) has evaluated these substances, and some jurisdictions have restricted their use in cosmetics and personal care items. Solace bands use nylon, which does not contain cyclosiloxanes—verified by independent laboratory analysis.

Phthalate Plasticizers

4

Phthalates are plasticizers used in some lower-quality silicone products to increase flexibility. Studies have documented phthalates in silicone wristbands and food storage containers. The Food Packaging Forum and peer-reviewed research have raised questions about their use in products with prolonged skin contact. Solace nylon bands are phthalate-free by composition—confirmed by lab testing.

Heavy Metals

5

Heavy Metals - Certain metals used as pigments, stabilizers, or manufacturing aids in lower-quality materials have raised concerns in consumer product testing. The Consumer Product Safety Commission (CPSC) regulates heavy metal content in products with skin contact, particularly for children's items. Solace bands are tested for heavy metals and meet all applicable safety standards.
