PVC / Vinyl
A chlorinated plastic — flexible or rigid
Also seen as: polyvinyl chloride, vinyl, soft vinyl, flexible PVC, resin code 3
At a glance
PVC is a plastic used in flooring, shower curtains, toys, rainwear, and packaging. Rigid PVC (pipes, window frames) is generally lower concern. Soft, flexible PVC is the bigger issue because it's made flexible by phthalates and other additives that can leach. PVC also requires chlorinated chemistry, creates dioxin in some manufacturing, and is hard to recycle.
Quick facts

What to do about it
Replace your vinyl shower curtain with cotton, hemp, or PEVA. Skip soft PVC baby toys when buying new.
Better choices
- Cotton, hemp, or PEVA shower curtains — no off-gassing
- Silicone, food-grade rubber, wood, or natural-fibre alternatives for baby items
- Linoleum, cork, or wood for flooring when renovating
Common questions
Each answer is tagged with how settled the evidence is: Established, Estimate, or To check.
What is PVC in simple terms?Established
PVC stands for polyvinyl chloride — a plastic made from chlorine and ethylene. It comes in two forms: rigid (used in pipes, window frames) and flexible (used in soft toys, shower curtains, flooring). To make it flexible, manufacturers add plasticizers — historically phthalates, which leach out over time.
Why is it used in everyday products?Established
Cheap, durable, water-resistant, flame-resistant (with additives), easy to colour. The flexible form is useful for anything that needs to bend without cracking — shower curtains, hoses, bath toys. The rigid form is structural.
What names does it go by on labels?Established
PVC, polyvinyl chloride, vinyl, soft vinyl, flexible PVC, and resin code 3 (the recycling number inside a triangle). "Vinyl" by itself is the most common everyday word.
Where do we commonly find it at home?Established
Vinyl flooring, shower curtains, soft toys (especially older ones), raincoats, faux leather, inflatable items, some cling wraps, pipes, window blinds, wallpaper, and waterproof bags.
How does exposure happen?Established
PVC items off-gas phthalates and other additives into indoor air, especially when new. The "new shower curtain smell" is exactly this. Skin contact with soft PVC items also transfers additives. Indoor dust from vinyl flooring and wallpaper can be a steady-state source.
How does it affect women, especially during pregnancy?Established
Most concerns route through the additives — phthalates, certain stabilisers, and indoor VOCs. Phthalates are linked to pregnancy and developmental outcomes in research. Reducing soft PVC during pregnancy is a low-cost precaution, especially for items used daily or installed nearby.
How does it affect men's health and fertility?Estimate
Same additive-driven concerns. Phthalates released from PVC products contribute to overall phthalate body burden, which has documented effects on male reproductive health at elevated levels.
How does it affect babies, children, and teenagers?Established
Higher concern. Babies and toddlers mouth soft PVC toys, and kids spend time on the floor where vinyl flooring sheds plasticisers into dust. Many countries have restricted several phthalates in children's toys for this reason — but older toys may still be present, and imported items aren't always compliant.
Does it affect older adults differently?To Check
Not the primary concern group. Indoor air quality matters more for anyone with asthma or COPD, regardless of age.
What does the strongest evidence say?Established
Strongest evidence is for phthalate migration from soft PVC, off-gassing of VOCs into indoor air (especially when new), and dust contamination from vinyl flooring. Lifecycle concerns (dioxin from manufacturing and burning) are well documented but less relevant to in-home use.
How serious is the risk from normal daily use?Estimate
Moderate for soft PVC items used daily, especially by children. Lower for rigid PVC (pipes inside walls). The realistic priority order: kids' toys, shower curtain, flooring, then everything else.
What are safer alternatives?Established
Cotton, hemp, polyester (acceptable), or PEVA for shower curtains. Silicone or natural rubber for baby items. Linoleum, cork, ceramic tile, or wood for flooring. The PVC-free options usually cost the same and last as long.
How easy or hard is it to avoid?Estimate
Easy for new purchases (alternatives are widely available). Harder for existing flooring or built-in items — replacement isn't usually justified unless you're already renovating.
What's one simple first step right now?To Check
Replace your shower curtain. Vinyl shower curtains off-gas constantly into a small humid space, and cotton or PEVA replacements cost about the same.
What this means for youEstimate
PVC is one of the easier materials to reduce, because the alternatives are widely available and not much pricier. Prioritise soft PVC items used by children or installed in heavily-used rooms. Don't tear out perfectly good flooring just because it's vinyl — wait until you're renovating.
Where can I find reliable information?To Check
EPA and CPSC on PVC and phthalates, EU REACH restrictions, and the Healthy Building Network on PVC alternatives. See References below.
