Essential Oil Labelling Is Complex
Essential oils are concentrated botanical extracts classified as hazardous chemical substances under UK CLP Regulation. Many essential oils are classified as skin irritants, sensitisers, flammable, or hazardous to the aquatic environment. This means every essential oil product you sell must carry CLP hazard labelling — in addition to any cosmetic regulations if the oil is marketed for use on skin.
CLP Classification
Common essential oil CLP classifications include:
- Skin sensitiser (H317): Almost all essential oils — lavender, tea tree, eucalyptus, citrus oils
- Skin irritant (H315): Many oils at higher concentrations
- Flammable liquid (H226): Oils with low flash points
- Aquatic toxicity (H400/H410/H411): Many terpene-rich oils
- Aspiration hazard (H304): Some oils if swallowed
Your CLP label must include the appropriate GHS pictograms, signal word, H-phrases, and P-phrases for your specific oil or blend.
Fitting Labels on Small Bottles
Essential oils typically come in 5ml, 10ml, 15ml, and 30ml bottles — some of the smallest containers in consumer products. Fitting all required information on these tiny surfaces is a major challenge.
Standard Dropper Bottle Label Sizes
- 5ml bottle: 30mm x 15mm (extremely limited space)
- 10ml bottle: 38mm x 20mm to 40mm x 22mm
- 15ml bottle: 42mm x 22mm to 45mm x 25mm
- 30ml bottle: 50mm x 25mm to 55mm x 30mm
- 100ml bottle: 70mm x 35mm to 80mm x 40mm
Solutions for Small Containers
CLP regulations allow reduced label requirements for containers under 125ml where space is insufficient for all required text:
- H-phrases and P-phrases may be omitted from the label if included on the outer packaging
- A fold-out label or peel-back label can provide additional space
- A QR code linking to full safety information can supplement the physical label
- Minimum pictogram size may be reduced to match available space (but must remain clearly visible)
Dual Classification
If you sell essential oils for aromatherapy use ON the skin, the product is also classified as a cosmetic and requires cosmetic labelling (INCI ingredients, CPSR, Responsible Person) IN ADDITION to CLP hazard labelling. If sold purely for burner/diffuser use, only CLP applies.
Material Requirements
Essential oil labels face unique challenges:
- Oil resistance: Spilled essential oil can dissolve some adhesives and inks. Vinyl with UV-cured inks is resistant.
- Small text legibility: Regulatory text on 10ml bottles must be printed at very small sizes. High-resolution printing (300+ DPI) is essential.
- Amber/dark bottles: Most essential oils come in dark glass. White or light labels provide necessary contrast for legibility.
