You Check Food Labels — But Do You Check Your Walls?

You read the back of every food packet before it goes into your shopping cart. You check if your drinking water is filtered. You verify that your child’s toys meet BIS standards. You research the thread count and dye quality of your bedsheets before purchasing.

But have you ever asked what chemicals are in the product that covers the single largest surface area in your home?

Your walls surround you. They are the backdrop to every meal, every night’s sleep, every hour your child spends playing on the floor. If those walls contain harmful chemicals, those chemicals are part of your home — silently, continuously, without your knowledge or consent.

Here is what you need to know about the chemicals found in wall décor products, and the international certifications that exist to protect you from them.

What Harmful Chemicals Are Found in Wallpaper?

PVC and Phthalates

PVC (polyvinyl chloride) is the most common material in commercial wallpaper — found in 96% of wallpapers tested in a major international study. PVC on its own is rigid, so manufacturers add phthalates to make it flexible. Phthalates are endocrine disruptors linked to reproductive disorders, hormonal imbalances, and cardiovascular damage. They leach out of the PVC matrix over time, entering your indoor air and settling into household dust.

The EU has banned several phthalates in children’s toys and childcare products. Yet in wallpaper — which covers far more surface area than any toy — these same chemicals remain largely unregulated in India.

Heavy Metals — Lead, Cadmium, Chromium, Mercury

A study by the Ecology Center found that over 50% of PVC-coated wallpapers tested contained lead, cadmium, chromium, and mercury. These heavy metals are used as colour enhancers, stabilisers, and anti-corrosion agents in pigments and coatings.

Lead exposure — even at low levels — affects brain development and cognitive function, particularly in children. Cadmium is a known carcinogen that accumulates in the body over years. Chromium(VI) is toxic to the skin, kidneys, and respiratory system. Mercury damages the nervous system.

These are not theoretical risks. These are chemicals documented in products currently sold to consumers around the world.

Formaldehyde and Formaldehyde Releasers

Formaldehyde is used in the resins that bind wood-based panels (including MDF used in wall art frames), in paper treatments, and in certain wallpaper adhesives. It is classified as a known carcinogen and mutagen by European regulatory bodies.

The EU is implementing strict new emission limits for formaldehyde in wall coverings and furniture, taking effect August 2026. Products exceeding 0.062 mg/m³ will be banned from sale across all member states.

Solvent-Based Inks

Many wall décor products are printed with solvent-based or UV-curable inks that contain a cocktail of organic solvents, reactive monomers, and photoinitiators. These chemicals release VOCs during printing, during the product’s lifespan, and during disposal. Some solvent-based ink components are classified as neurotoxicants and reproductive hazards.

Water-based inks — particularly latex-based formulations — eliminate the need for organic solvents entirely, producing prints that are chemically safer from production through to end-of-life.

What Is EU REACH Compliance and Why Does It Matter for Home Décor?

What REACH Covers

REACH — Registration, Evaluation, Authorisation, and Restriction of Chemicals — is the European Union’s master regulation for chemical safety. Adopted to protect human health and the environment from the risks posed by chemicals, it is one of the most comprehensive chemical regulatory frameworks in the world.

REACH maintains a growing list of Substances of Very High Concern (SVHCs) — chemicals identified as carcinogens, mutagens, reproductive toxicants, persistent bioaccumulative substances, or endocrine disruptors. These substances are either banned outright or subject to strict authorisation requirements before they can be used in products sold in the EU.

Substances of Very High Concern (SVHCs)

The SVHC list currently includes hundreds of chemicals. Products containing SVHCs above 0.1% concentration must be declared. Many SVHCs commonly found in wall décor materials — including certain phthalates, lead compounds, cadmium compounds, and chromium(VI) — are either restricted or on the candidate list for authorisation.

When a product is declared REACH compliant, it means every chemical in its composition — inks, substrates, coatings, adhesives — has been evaluated against this comprehensive restricted substances framework.

What This Means for Your Home

Our materials are REACH compliant. This is the same standard that governs products sold in Paris, Berlin, Amsterdam, and Stockholm. Every chemical in our inks and substrates has been evaluated against the EU’s restricted substances list.

India has no equivalent of REACH for home décor products. Products containing SVHCs that are banned or restricted in European markets are freely available in Indian stores and on Indian e-commerce platforms. When a wall décor brand in India cannot tell you its REACH compliance status, that is a significant red flag.

What Does ZDHC Certified Mean?

Zero Discharge of Hazardous Chemicals Explained

ZDHC stands for Zero Discharge of Hazardous Chemicals. The ZDHC Roadmap to Zero programme maintains a Manufacturing Restricted Substances List (MRSL) — a comprehensive list of chemical substances banned from intentional use during manufacturing processes.

The ZDHC MRSL is not about what ends up in the final product. It is about what chemicals are used — or deliberately not used — at every stage of the production process.

Why Manufacturing Process Matters, Not Just the Final Product

This is a critical distinction that many consumers and even brands overlook. REACH regulates the final product — what is in the wallpaper or wall art that reaches your home. ZDHC regulates the manufacturing process — ensuring that hazardous chemicals are not used at any stage of production, even if they might not appear in the finished product.

Why does this matter? Because manufacturing processes that use hazardous chemicals can leave residual traces that are difficult to detect in final testing but still present in the product. And because responsible manufacturing means protecting not just the end consumer, but also the workers in the production facility and the environment surrounding it.

What This Means for Your Home

Our inks conform to the ZDHC Manufacturing Restricted Substances List at Level 1. This means our production process is clean from start to finish — not just the end result.

When you bring a BestOfBharat product into your home, you are not just getting a product that tested clean. You are getting a product that was made clean.

Can Wall Décor Cause Allergic Reactions? Why Nickel-Free Matters

Nickel as a Contact Allergen

Nickel is one of the most common contact allergens in the world. An estimated 10–20% of the global population has some degree of nickel sensitivity. For these individuals, prolonged skin contact with nickel-containing materials can trigger contact dermatitis — itching, redness, rash, and in severe cases, blistering.

Where Nickel Appears in Wall Décor

Nickel is found in many printing pigments, particularly in metallic and certain colour inks. It can also be present in coatings and surface treatments. While you might not think of wallpaper as a “skin contact” product, consider how often hands brush against walls, how children lean and press against wall surfaces, and how wall stickers are handled during application.

What This Means for Your Home

Our inks are verified nickel-free through the UL ECOLOGO certification process. For the millions of people with nickel sensitivity — and for families with young children who interact physically with wall surfaces daily — this is a meaningful health safeguard that most wall décor brands do not offer or even consider.

Is Wallpaper Made in India Safe?

This is the honest answer: it depends entirely on the brand.

India does not have regulatory frameworks equivalent to EU REACH, ZDHC, or GREENGUARD GOLD for wall décor products. This means there is no government body testing wallpapers, wall art, or wall coverings for chemical safety before they reach the market. The safety of a product depends entirely on whether the manufacturer voluntarily chooses to meet international standards and submit to third-party testing.

Some Indian manufacturers produce wall décor that would comfortably meet European standards. Others use materials and inks that would be restricted or banned in the EU. Without regulation, the consumer has no reliable way to distinguish between the two — unless the brand provides transparent, verifiable certification.

How BestOfBharat Meets Chemical Safety Standards

We meet three layers of chemical safety verification:

EU REACH Compliance — every chemical in our products evaluated against the EU’s restricted substances list, including SVHCs.

ZDHC Roadmap to Zero Level 1 — our manufacturing process itself is free from hazardous chemicals, not just the final product.

Nickel-Free Verified — our inks contain no nickel, protecting the 10–20% of people with nickel sensitivity.

These chemicals do not just sit inert in your walls — they release into the air you breathe. Learn how we protect your indoor air quality: Is Your Wallpaper Affecting the Air You Breathe?
