Two codes that start with "EUH" keep turning up on fragrance safety data sheets — EUH208 and EUH210. They look alike and sit side by side, but they do completely different jobs, and mixing them up puts the wrong text on your label.

The one-line version

  • EUH208 — "Contains (name). May produce an allergic reaction." It names a specific allergen in the product.
  • EUH210 — "Safety data sheet available on request." It points to a document, and names nothing.

Both are supplemental statements defined in Annex II of CLP. That's all they have in common.

EUH208: a warning about an allergen

EUH208 is about allergen declaration. When a fragrance allergen classified as a skin sensitiser is present above its labelling threshold — generally 0.1% in the finished product — but below the level that would classify the whole product as a sensitiser, you still have to warn people. EUH208 does that by naming the substance: "Contains citronellol. May produce an allergic reaction." Each allergen over the threshold is named, so the reader learns exactly what they might react to.

EUH210: a pointer to the safety data sheet

EUH210 has nothing to do with allergies. It says one thing — the safety data sheet for this product can be requested. It appears when a mixture isn't classified as hazardous (so it carries no pictogram or signal word) but still contains hazardous substances above the thresholds that make an SDS available on request under REACH. In other words, a product can look completely hazard-free on the front and still need EUH210 on the back, quietly telling a customer they can ask for the full document.

When each one applies to a candle

Whether your candle needs either statement comes down to its finished-product classification, worked out from the fragrance's data and your fragrance load:

  • Neither — the finished product is unclassified, holds no allergen over the threshold, and no substance that triggers the SDS-on-request rule.
  • EUH208 only — an allergen crosses 0.1% but the product isn't otherwise classified and doesn't trip the EUH210 rule.
  • EUH210 only — the product isn't classified and carries no over-threshold allergen, but does contain hazardous substances above the SDS-on-request thresholds.
  • Both — an unclassified candle can name an allergen (EUH208) and point to its SDS (EUH210) on the same back label.

Once a product is classified as hazardous — the common case for a fragranced candle, carrying pictograms and a signal word — it usually falls under the ordinary SDS rules rather than EUH210, while EUH208 can still apply to any allergen below the classification cut-off.

Getting it right

The two statements answer different questions — "what might I react to?" and "where's the full safety document?" — so a compliant label often has to resolve both at once. Molekule works out your finished product's classification from the fragrance data and your load, then puts the right statements — EUH208 with the correct allergens named, EUH210 when it's due — on the label for you.
