Reed diffuser and room spray labels: what CLP asks for
Published 22 September 2026; rules last checked 25 September 2026. A labelling reference, not legal advice.
The same eight label elements as a candle, from the same regulation, but the classification is usually heavier, and two of the hazards it often carries reach past the label into the packaging: a child-resistant closure and a tactile warning of danger. A reed diffuser is a fragrance dissolved in a solvent and a room spray is a fragrance in alcohol or water, so the mixture is mostly the things that burn or that harm if swallowed, rather than wax. Whether yours is classified, and for what, is decided by your supplier's data for the finished liquid; the label and the packaging follow from that.
What the classification often adds
- Flammability. Annex I Table 2.6.1 classifies a liquid by flash point: category 3 for a flash point of 23 °C to 60 °C (H226, "Warning"), category 2 below 23 °C with an initial boiling point above 35 °C (H225, "Danger"), category 1 below 23 °C with a boiling point of 35 °C or lower (H224). An alcohol-based room spray is commonly in category 2; a diffuser base can sit in category 3 or outside the class, depending on the solvent.
- Aspiration hazard. Annex I 3.10.3.3.1.2 classifies a mixture in category 1 when the sum of its category 1 ingredients is 10 % or more and its kinematic viscosity is 20,5 mm²/s or less at 40 °C. A thin hydrocarbon diffuser base is the textbook case: GHS08, "Danger", H304 "May be fatal if swallowed and enters airways" (Table 3.10.2).
- Eye irritation and skin sensitisation. H319 and H317 arrive with the fragrance at a higher load than a candle's, along with EUH208 or the named sensitisers.
- Aquatic hazards. H411 or H412 as for candles, from the fragrance materials.
With more hazards come more pictograms and the precedence rules: one signal word, "Danger" if any class calls for it (Article 20(3)), and Article 26 thinning the pictograms. The tool applies both. Precautionary statements are selected for the use, not looked up, and a diffuser's set is longer than a candle's; the tool leaves that selection to you and your supplier and prints what you choose.
Beyond the label: what Article 35 adds to the bottle
Article 35(2) of CLP governs packaging supplied to the general public, and two of its requirements are triggered by hazards a diffuser commonly has:
| Packaging requirement | Triggered by (Annex II Part 3) | Standard |
|---|---|---|
| Child-resistant fastening | Aspiration hazard (3.1.1.2), except aerosols and containers with a sealed spray attachment; acute toxicity categories 1 to 3, STOT categories 1, skin corrosion 1 (3.1.1.1); and, whatever the classification, 3 % or more methanol or 1 % or more dichloromethane (3.1.1.3) | EN ISO 8317 for reclosable packages (3.1.2) |
| Tactile warning of danger | Aspiration hazard, flammable liquids categories 1 or 2, acute toxicity, skin corrosion, respiratory sensitisation, STOT 1 or 2, and others (3.2.1.1); aerosols and sealed-spray containers classified only for aspiration hazard are excepted (3.2.1.2) | EN ISO 11683 (3.2.2) |
So a reed diffuser classified H304 needs a child-resistant closure and a tactile triangle on the packaging, whatever its size; a room spray in category 2 for flammability needs the tactile warning; and a candle classified only for skin sensitisation and aquatic hazards needs neither. These are bought-in features of the bottle and cap, not something a label printer supplies, so they belong in the packaging decision before the label is designed. Article 35(2) also bars packaging that would attract children or that resembles a food, feed, medicinal or cosmetic product in a way that misleads.
Pump sprays and pressurised aerosols
A pump or trigger spray is a liquid in a bottle; its classification is the liquid's, and the tool handles it. A pressurised aerosol can is a different hazard class with its own statements (H222, H223, H229) and its own packaging rules; our table does not yet include it, so the tool cannot produce that label: the aerosol statements would have to be added by hand.
Regions
Article 35 and Annex II Part 3 read the same in EU CLP and GB CLP. The differences are the ones the candle pages describe: no UFI or poison-centre duty in Great Britain, English on the GB label, and, for EU and Northern Ireland labels placed on the market from 1 January 2028, the minimum font size and black-on-white rules described on the placement page.
In the United States CLP does not apply: a diffuser or spray takes the warning of the Federal Hazardous Substances Act instead, with no pictograms. US reed diffuser and room spray labels covers it.
Related questions
Does a reed diffuser need a UFI?
In the EU and Northern Ireland, yes when it is classified for a health or physical hazard, which flammability, aspiration hazard, eye irritation and skin sensitisation all are, so most classified diffusers do. In Great Britain there is no UFI or poison-centre duty. The UFI page has the detail.
My room spray is in a pump bottle. Is it an aerosol under CLP?
An aerosol under CLP is a pressurised dispenser; a pump or trigger spray is not pressurised, so the liquid is classified as a liquid, most often for flammability by its flash point. Our home-fragrance tool covers the flammable-liquid classes; pressurised aerosol cans, whose label carries H222, H223 or H229, are not in its table: a label for one needs those statements, and anything they bring, added by hand.
Where do the tactile triangle and the child-resistant cap come from?
From Article 35(2) of CLP and Annex II Part 3, which are packaging rules rather than label elements. Annex II 3.1.1.2 requires child-resistant fastenings on packaging supplied to the general public containing a mixture classified for aspiration hazard, and 3.2.1.1 requires a tactile warning for, among others, aspiration hazard and flammable liquids of category 1 or 2. Annex II 3.1.1.3 adds two substances whatever the classification: 3 % or more methanol, or 1 % or more dichloromethane, also calls for child-resistant fastenings. Apart from those two, both come from the classification, so the supplier's document tells you whether your bottle needs them.
Can the diffuser bottle look like a perfume bottle?
Article 35(2) says packaging for the general public shall not have a shape or design likely to attract or arouse the active curiosity of children or to mislead consumers, nor a presentation or design used for foodstuffs, animal feed, medicinal or cosmetic products which would mislead consumers. A diffuser dressed as a perfume, or a room spray that reads as a body spray, is the case that sentence is about.
