Why PFAS Are Becoming a Global Concern
Per- and polyfluoroalkyl substances (PFAS) are a group of thousands of synthetic chemicals widely used across industries because of their exceptional chemical stability and resistance to heat, water, and oil.
These chemicals contain carbon-fluorine (C-F) bonds, one of the strongest in organic chemistry. While this property makes PFAS highly useful in manufacturing, it also makes them extremely persistent in the environment and human body. Because they do not easily break down, PFAS are commonly referred to as “forever chemicals,” and our Regulatory Publishing & Submission Services help healthcare companies stay compliant and ahead of global regulations.
In recent years, growing scientific evidence has linked PFAS exposure to environmental contamination and potential health risks, prompting governments around the world to introduce stricter PFAS regulations and bans.
For the healthcare sector, which relies heavily on PFAS in medical devices and pharmaceutical manufacturing, these regulatory changes present significant operational and compliance challenges.
What Are PFAS Chemicals?
PFAS are fluorinated chemical compounds that contain at least one fully fluorinated carbon atom such as:
Perfluorinated methyl group (CF₃)
Perfluorinated methylene group (–CF₂–)
These compounds are used in a wide variety of applications due to their chemical stability, durability, and non-reactive properties, as explained in our detailed Toxic Chemicals in Everyday Products blog.
However, their persistence means they can accumulate in water, soil, wildlife, and human bodies, leading to increasing regulatory scrutiny worldwide.
Types of PFAS Substances
PFAS chemicals are generally classified into two main categories.
1. Polymeric PFAS
Polymeric PFAS are large molecules made of repeating units. Because of their size and structure, they tend to be less mobile in the environment and are considered to pose relatively lower environmental risk.
These substances are widely used in industrial applications and medical device manufacturing.
Common uses include:
Fluoropolymer coatings
Medical implants
Medical packaging materials
Industrial processing aids
2. Non-Polymeric PFAS
Non-polymeric PFAS are smaller molecules that can move more easily through soil and water.
Because of their mobility and persistence, they are considered more environmentally harmful and have been linked to global contamination concerns.
These PFAS are sometimes used as processing aids during manufacturing, including in medical device production.
Why PFAS Are Important in Healthcare
Despite environmental concerns, PFAS chemicals remain critical for healthcare technologies because they provide properties that are extremely difficult to replicate with other materials.
Key properties of PFAS include:
High chemical and thermal stability
Resistance to corrosion
Oil and water repellence
Low friction (lubricity)
Low surface energy
Excellent electrical insulation
Biocompatibility for medical applications
These properties make PFAS essential for medical device performance, safety, and durability.
PFAS in Medical Devices
Many life-saving medical devices rely on fluoropolymers, a subset of PFAS.
Examples include:
Cardiovascular stents
Pacemakers
Vascular grafts
Catheters
Guidewires
According to the U.S. Food and Drug Administration (FDA), there are currently no alternative materials that fully replicate the critical functions of fluoropolymers in certain medical devices.
Common medical device applications
1. Surgical meshes and wound treatment
Materials like expanded PTFE (ePTFE) and PVDF are used in surgical meshes and wound treatment because they reduce tissue adhesion.
2. Medical implants
Fluoropolymers such as PTFE and FEP are commonly used in implants due to their stability and biocompatibility.
3. Low-friction coatings
PFAS coatings reduce friction, helping medical devices move smoothly during procedures and reducing tissue damage.
4. Medical packaging
Fluoropolymers provide strong barrier protection against moisture and contamination, helping maintain product sterility.
5. Manufacturing equipment
Non-stick PFAS coatings help prevent contamination in pharmaceutical and medical device production facilities.
PFAS in the Pharmaceutical Industry
The pharmaceutical industry also depends on PFAS for drug manufacturing, packaging, and delivery systems.
Key applications include
Active Pharmaceutical Ingredients (APIs)
More than 300 fluorinated drugs have been approved over the past decades, and hundreds more are currently in clinical trials.
Excipients
Fluorinated gases are used as propellants in metered-dose inhalers (MDIs) for respiratory medicines.
Solvents and reagents
Chemicals such as trifluoroacetic acid (TFA) are used in pharmaceutical manufacturing and laboratory analysis.
Drug delivery systems
PFAS materials may be used in:
Seals
Filters
Lubricants
Drug delivery components
Pharmaceutical packaging
Fluoropolymers protect medications from humidity and chemical degradation, helping extend shelf life.
Harmful Effects of PFAS
PFAS chemicals are often categorized as Persistent, Bioaccumulative, and Toxic (PBT) substances.
Key concerns include:
Environmental persistence
Bioaccumulation in humans and wildlife
Long biological half-life in the human body
For example, some PFAS remain in the body for years:
PFOA: 2.1–10 years
PFOS: 3–27 years
PFHxS: up to 35 years
Scientific studies have associated PFAS exposure with potential health effects such as:
Immune system disruption
Hormonal changes
Liver damage
Developmental effects
Increased risk of certain cancers
Because PFAS are found globally even in remote regions their impact is considered a major public health challenge.
Global PFAS Regulations Are Increasing
Governments worldwide are introducing stricter PFAS regulations and bans to reduce environmental contamination, and our Global eCTD Submission Services help companies stay compliant with these evolving requirements.
European Union
The European Chemicals Agency (ECHA) has proposed one of the largest PFAS restrictions ever under the REACH regulation, targeting nearly 10,000 PFAS substances.
If implemented, the restriction could come into force around 2029–2030.
United States
In the U.S., the Environmental Protection Agency (EPA) is expanding PFAS regulation through:
PFAS reporting requirements under TSCA
Drinking water limits for several PFAS chemicals
Classification of certain PFAS as hazardous substances
Other Countries Taking Action
Several countries are strengthening PFAS policies:
Canada – bans on PFOS and PFOA production and use
Japan – ban on 138 PFAS chemicals starting 2025
Australia – national PFAS restrictions beginning in 2025
China – gradual restrictions under pollution control policies
These regulations are pushing industries worldwide to reduce or eliminate PFAS usage.
How the PFAS Ban Could Impact Healthcare
Stricter PFAS regulations could significantly affect the medical device and pharmaceutical industries.
Key impacts include
Supply chain disruptions
Major chemical manufacturers have already announced plans to exit PFAS production, which could reduce raw material availability.
Higher manufacturing costs
Developing and qualifying PFAS alternatives requires significant research and testing.
Product development delays
New materials may require regulatory approvals and safety validation, slowing product launches.
Market access risks
Companies that fail to comply with PFAS regulations may lose access to regulated markets.
Strategies for PFAS Compliance in Healthcare
Healthcare manufacturers must develop proactive strategies to manage PFAS restrictions.
1. Portfolio assessment
Companies must first identify where PFAS are used in their products, components, packaging, and manufacturing processes.
This includes:
Supplier data collection
Material audits
Manufacturing process reviews
Documentation and traceability
2. PFAS testing
When supplier information is unclear, laboratory testing may be required.
Common testing methods include:
LC-MS/MS targeted PFAS analysis
Total oxidizable precursor (TOP) assay
