On 7 December 2023, the European Chemicals Agency (ECHA) announced that its Risk Assessment Committee (RAC) had adopted eight opinions on proposals for harmonised classification and labelling (CLH).

Tea Tree
Tea tree (Melaleuca alternifolia) extracts and essential oil (CAS: 85085-48-9 / 68647-73-4; EC: 285-377-1) are ingredients listed in the CosIng, with different functions: antioxidant, fragrance…).

The classification proposal
Poland has proposed classifying them: as:

• Acute Tox. 4, H302 - Harmful if swallowed, oral: ATE = 1049 mg/kg bw
• Acute Tox. 4, H332 - Harmful if inhaled, inhalation: ATE = 3.64 mg/L (mist)
• Skin Irrit. 2, H315 - Causes skin irritation
• Skin Sens. 1B, H317 - May cause an allergic skin reaction
• Repr. 2, H361f - Suspected of damaging fertility
• Asp. Tox. 1, H304 - May be fatal if swallowed and enters airways
• Aquatic Acute 1, H400 - Very toxic to aquatic life, M-factor M = 1
• Aquatic Chronic 3, H412 - Harmful to aquatic life with long lasting effects
The RAC opinion
The RAC agreed that these substances should be classified as:
• Repr. 1B, H360F - May damage fertility
• Repr. 2, H360d - Suspected of damaging the …
