Material Safety Data Sheets and CLP labelling information for wax melts

Wax melts are considered to be mixtures under both REACH and CLP as they are blends of wax, fragrances and possibly colourants. The duties that apply to small scale home-based suppliers are the same as larger scale suppliers, and are as follows...


When businesses are considering what information should be on a label or whether one is in fact needed, the requirements are very much dependent of the substances used in the wax melts and their respective hazard classification. This has to be determined separately for each of our wax melt formulations individually, as they will each have different ‘ingredients’. The main concern for wax melts is likely to come from the fragrances used. In particular, a number of common fragrances containing essential oils are classified as ‘sensitisers’ (i.e., they can cause allergic reactions) and this can manifest at very low concentrations. For mixtures containing substances that are classified as sensitisers at a concentration of 0.1% or above, there will generally be a requirement to include some information about this hazard on the label of the product. For example, you may have noticed the use of the statement 'Contains (Name of sensitising substance) listed on some of our labels. Or "May produce an allergic reaction". Such a statement serves to warn our customers who are already sensitised to a particular substance. If a sensitising substance was present at higher concentrations (generally higher than 1%) the entire mixture would be classified as a sensitiser and would need to carry a pictogram (e.g., the exclamation mark symbol), a hazard statement (e.g., May cause an allergic skin reaction) and precautionary statements about safe use.

Substances can be classified for other hazards (e.g., skin irritation, eye irritation, hazardous to the aquatic environment etc.). From common composition of wax melts these are less likely to be applicable, but if ingredients are classified for other hazards (which can be ascertained from the MSDS the supplier passes to the producer) the business will need to consider whether or not they are relevant to the wax melt. This will be based on the concentration of the substance in the final wax melt mixture. However, there are different concentrations to consider for the different hazards (e.g., if an ingredient is classified as a skin irritant, it would generally trigger classification of the mixture as a skin irritant only when present at 10% or above).


If for any reason you would like a copy of the material data sheet for any of our wax melts, we are more than happy to provide one, and a full list can be found below. We can also provide a PDF containing all the relevant CLP labelling and warnings for each individual fragrance oil should you have any allergies and/or be concerned about concentration levels of any oils used. None of our wax melt mixtures exceed 10% fragrance oil. The safety of our customers is our main concern, and as such we strictly adhere to the regulations for fragrance limits set out in each of our individual MSDS sheets. Even if the fragrance oil and wax allow for higher percentages to be used, we feel our wax melts have a strong enough aroma without exceeding their maximum allowances. For a paper copy of individual or multiple MSDS sheets or any of our CLP labelling PDF's, please contact us via our email
