10% CLP Labels for Wax Melts & Sizzlers & Carpet Fresheners SQUARES + Combined Warning Label
CLP labels for wax melts are the hazard labels required in the UK when a scented melt contains enough fragrance oil to be classed as hazardous. This page covers the square 10% label with a combined warning panel, which is a common format for clamshells, sizzlers and carpet fresheners. The sticker is small, usually around 40 x 40 mm, so every line has to earn its place.
The "10%" refers to the fragrance load in the melt. At that level, many fragrance oils bring the finished product into a labelling requirement, because the oil's own classification carries through at the concentration used. Check the supplier's safety data sheet first. The label comes second.
What a wax melt CLP label must show
A compliant label is built from your supplier's data and your own details. Nothing on it should be guessed.
- The signal word, usually "Warning" or "Danger"
- The hazard pictogram, such as the exclamation mark or the environmental symbol
- Hazard statements (H phrases) and precautionary statements (P phrases)
- The names of the hazardous ingredients, taken from the SDS
- Supplier name, address and phone number
- Nominal quantity, for example 50 g or 90 g
Pictograms need a red diamond border and must take up at least one fifteenth of the label's surface area, with a minimum of 1 cm². On a small square, that rule decides how much space is left for text.
Wax melt CLP: the combined warning label
A combined label puts the CLP panel and the general safety wording on one sticker. That means fewer stickers per pack and less handling. The extra wording normally covers things like keeping the melt away from children and pets, never leaving a burner unattended, and using a suitable warmer only.
The trade-off is space. With a lot of H and P statements, a 40 mm square gets crowded and the type shrinks. If the text drops below roughly 1.2 mm x-height, readability becomes a problem and a larger or two-part label is the better choice. Many sellers print the full statements on the back of the pack and keep the front sticker for pictogram and signal word, as long as the required information stays on the label itself.
CLP labels wax melts: square sizes and fit
Squares suit flat clamshells, snap bars and sachets. Typical sizes run from 30 mm up to 50 mm, and the 40 mm version is the usual compromise. Use a matt or gloss white paper stock for dry packaging. For packs that sit near warmth or get handled a lot, a vinyl stock holds up better, since paper can curl and lift.
Keep the label off the seal edge. Peeling a sticker that sits across the opening is how information ends up torn in half.
CLP for wax melts versus candles and diffusers
The rules are the same, but the percentage and the format change. If you also make candles, the guide to clp labels for candles covers round and rectangular formats at the same 10% level. Reed diffusers, room sprays and Hoover discs often use a different fragrance load, and the 25% CLP Labels For Diffusers page shows how the wording shifts at that strength. Browse the wider clp wax melts range of label types if you are unsure which format matches your product.
Sizzlers melts: what they are
Sizzlers are scented wax pieces, often in clear or coloured chunks, sold in bags or tubs and melted in a warmer. They are the same product family as snap bars, only usually made with a higher fragrance load and a texture that is closer to crumbled wax. Carpet fresheners follow a similar idea, with the scented granules sprinkled and vacuumed up.
Because the fragrance load is often 8 to 10%, they usually need a CLP label. Guessing is risky, so calculate it from the actual oil percentage.
Frequently Asked Questions
How to make sizzlers melts?
Melt soy or paraffin wax to about 75 to 80°C, add fragrance oil at 8 to 10% by weight and stir for two minutes. Pour into a thin tray or mould and let it set for several hours. Break or cut it into chunks, then pack and label them.
Do all wax melts need a CLP label?
No. It depends on the fragrance oil's classification and the amount used. Read the SDS, calculate the concentration of each hazardous ingredient in the finished melt, and label if the thresholds are reached.
Can I use one label for different scents?
Only if the hazard information is identical. Different oils usually carry different statements and ingredient names, so each scent normally needs its own version.
What size should a square CLP label be?
Around 40 x 40 mm works for most small packs. Go larger when the text is long, since the pictogram minimum and legibility both limit how far you can shrink it.
