Polytetrafluoroethylene (PTFE) Fiber

Thermal decomposition products may cause polymer fume fever if overheated, minimal dermal or inhalation risk at typical use, potential respiratory irritation from fumes

Polystyrene

Potential styrene leaching, environmental pollution, not biodegradable

Polyurethane

Potential irritant and sensitizer on skin contact, respiratory sensitization risk during aerosol or dust exposure, possible contamination with residual isocyanates during manufacturing

Polymeric coating

Surface protection, moisture barrier, enhanced durability

Mint flavoring agents

Flavor enhancement, consumer sensory appeal, mild antibacterial properties

Polyethylene Glycol

Good solvent and solubilizing agent, humectant properties, generally low toxicity, enhances cleaning efficacy

Polyvinyl Alcohol

Film-forming agent, stabilizer, biodegradable

Polyacrylate
