If you have been researching flame retardant sprays for curtains, upholstery, stage textiles or any other fabric application, you may have come across a term that is becoming increasingly important: bromine-free. It is not just a marketing phrase. It reflects a wider shift in how regulators, specifiers and procurement teams are thinking about fire safety chemistry, and it has real implications for the products you buy today.
What Are Brominated Flame Retardants?
Brominated flame retardants, often referred to as BFRs, are a class of chemical compounds that have been used for decades to reduce the flammability of plastics, foams, textiles and other materials. They work by interfering with the chemical chain reactions that sustain combustion.
For many years, brominated flame retardants were widely used because they are effective and relatively low cost. They have appeared in a wide range of consumer and commercial products, including electronics, furniture, insulation materials and some textile applications.
The concern is not simply how these chemicals perform in a fire. It is also what can happen to certain brominated flame retardants during everyday use, disposal and long-term environmental exposure.
The Health and Environmental Case Against Certain Brominated Flame Retardants
The evidence around some brominated flame retardants, particularly polybrominated diphenyl ethers, known as PBDEs, has been building steadily. Certain BFRs do not chemically bind permanently to the materials they are used in. This means they can migrate out over time, accumulating in dust, entering the food chain and building up in people, animals and the wider environment.
Research has linked long-term exposure to certain brominated flame retardants with health concerns including endocrine disruption, neurodevelopmental effects, immune system effects and reproductive harm. Children can be considered particularly vulnerable because of hand-to-mouth contact with dust and surfaces.
There are also concerns around what can be released when products containing some brominated flame retardants burn or are disposed of incorrectly. Certain halogenated flame retardants can contribute to the formation of hazardous combustion by-products, which is one of the reasons regulators are paying closer attention to this area.
What Regulators Are Doing About It
The regulatory picture has shifted significantly in recent years.
In March 2023, the European Chemicals Agency, ECHA, published its Regulatory Strategy for Flame Retardants, identifying aromatic brominated flame retardants as candidates for a possible EU-wide restriction under REACH. In December 2024, ECHA raised environmental concerns over many aromatic brominated flame retardants identified as being on the EU market, recommending a group-wide approach to avoid one problematic compound simply being replaced with another.
The EU has also moved to tighten concentration limits for some restricted brominated flame retardants in products, including PBDEs. This reflects a clear direction of travel toward greater scrutiny of persistent, bioaccumulative and halogenated flame retardant chemistry.
The UK is currently moving more slowly than the EU in some areas, but the direction is similar. Procurement teams in hospitality, healthcare, education and public sector buildings are increasingly asking suppliers to confirm the halogen status of fire treatment products.
What Bromine-Free Means in Practice
A bromine-free flame retardant achieves fire protection without using brominated chemistry. Depending on the formulation, this may involve mechanisms such as promoting char formation, absorbing heat or helping to reduce the spread of flame through alternative non-halogenated chemistry.
For textiles in particular, including curtains, upholstery, bedding, costumes and stage drapery, this matters. These are materials that people live and work with every day, often in close proximity. Hotels, care homes, nurseries, theatres and public buildings have a duty of care not just for fire safety, but also for the suitability of the products used in occupied environments.
When correctly applied to suitable absorbent materials and supported by the relevant test evidence, a bromine-free treatment can help meet required fire-performance standards without relying on brominated or halogenated chemistry.
Flametect Nitro: Bromine-Free from Day One
Flametect Nitro has never contained bromine, halogens or formaldehyde. Its water-based formula was developed with environmental and human safety as an important design consideration, not as an afterthought.
This means:
- Bromine-free, halogen-free and formaldehyde-free formulation
- Does not rely on halogenated chemistry, helping avoid the specific concerns associated with many brominated flame retardants
- Water-based and non-hazardous in normal use when applied as directed
- Tested as non-irritant with a neutral pH
- Aligned with the direction of current regulatory scrutiny around halogenated and brominated flame retardants
- Suitable for use on appropriate absorbent textiles in settings such as hotels, care homes, nurseries and healthcare environments, subject to correct application and the required fire-performance evidence
Flametect Nitro achieves certified fire protection to BS 5867 Part 2 Type B, BS 5438, French M1, German DIN 4102, USA NFPA 701, California Fire Marshal Title 19 Section 1237 and a total of nine international fire safety standards, all without brominated or halogenated chemistry.
For outdoor and more demanding environments, Flametect Nitro D offers the same bromine-free and halogen-free approach in a water-resistant formulation, suitable for tents, marquees, canvas and outdoor textiles.
What to Look for When Buying a Flame Retardant Spray
If you are specifying or purchasing a flame retardant treatment for textiles, it is worth asking your supplier directly: does this product contain bromine or other halogens? If they cannot answer that question clearly, that is a signal in itself.
The fire safety industry has historically been slow to communicate the chemistry behind its products. That is changing, partly because customers are asking better questions, and partly because regulation is forcing greater transparency.
At Eco-Sol, we can always answer that question. Flametect Nitro is bromine-free, halogen-free, formaldehyde-free and non-hazardous in normal use when applied as directed. It is also independently tested to a wide range of recognised UK and international fire safety standards.
Frequently Asked Questions
Are all flame retardant sprays bromine-free?
No. Some flame retardant products, especially in certain historic, industrial or specialist applications, have used brominated or halogenated chemistry. Always check the Safety Data Sheet, also known as the SDS, or ask the manufacturer directly whether the product contains halogens, bromine or formaldehyde.
Is bromine in flame retardants harmful?
Not every brominated compound should be described in exactly the same way, but certain brominated flame retardants have been linked to environmental persistence, bioaccumulation and health concerns including endocrine, neurological and reproductive effects. This is why regulators are paying close attention to aromatic brominated flame retardants and related chemistry.
Does bromine-free mean less effective fire protection?
No. Flametect Nitro is certified to nine international fire safety standards including BS 5867 Part 2 Type B and USA NFPA 701, achieved without brominated chemistry. Bromine-free does not mean reduced performance. It means the fire-retardant effect is achieved through a different chemical route.
What textiles can Flametect Nitro be used on?
Flametect Nitro can be used on suitable absorbent natural fibres, synthetic textiles, blended fabrics, foams, paper, card, hay, straw and many absorbent decorative materials. The material must be absorbent for the treatment to penetrate correctly.
Is Flametect Nitro safe for use in care homes and nurseries?
Flametect Nitro has a neutral pH and has been independently tested as non-irritant. It is suitable for use on appropriate absorbent textiles in care homes, nurseries, hotels and similar environments when applied correctly and when the treated material meets the required fire-performance standard for its intended use.
What is the difference between Flametect Nitro and Flametect Nitro D?
Flametect Nitro is the standard formulation for interior textiles. Flametect Nitro D is a water-resistant version designed for outdoor and damp environments including tents, marquees, yurts and canvas structures. Both are bromine-free and halogen-free.
