Certificates of Analysis
A Certificate of Analysis records what testing showed for a specific lot: identity, appearance, odour conformity, and the relevant physical constants or assay figures for that material.
We have not yet published Certificate of Analysis documents for the catalogue. They are available per material on request — ask us and we will send the current document for the grade you intend to use.
Certificates of Analysis are issued per lot and supplied on request rather than published in advance — the document that matters is the one for the bottle you received.
Allergen statements
An allergen statement declares the content of the fragrance allergens that must be labelled on cosmetic products in the EU, UK and a growing number of other markets. It is a separate obligation from IFRA: IFRA restricts how much you may use, allergen labelling governs what you must declare.
We have not yet published allergen statement documents for the catalogue. They are available per material on request — ask us and we will send the current document for the grade you intend to use.
Allergen statements are supplied per material and lot on request.
Allergen content varies by lot, particularly in naturals. A statement for one lot of bergamot does not describe the next. If you are compiling a Cosmetic Product Safety Report, use the statement issued for the lot you actually formulated with.
Published specifications
Every material in the catalogue carries specification data on its own page, which is often enough to answer a question without needing a document at all. Where we hold it, we publish:
- CAS number, chemical name and synonyms
- Odour description, note behaviour, strength and substantivity
- Suggested working range and evaluation dilution
- Appearance, solubility, flash point and shelf life
- Storage guidance and manufacturer or origin
- Useful pairings and example accords
Odour descriptions, working ranges and example accords are formulator's guidance, not a specification, and are not a warranty of suitability for a particular purpose. The figures that constitute a specification are the analytical ones, and those come from the lot document.
Why lot matters
Synthetic aroma chemicals are generally consistent between lots. Naturals are not — an essential oil is an agricultural product, and colour, viscosity, constituent profile and odour shift with harvest, origin and season. That variation is a property of the material rather than a defect, and it is the reason certificates are issued per lot rather than per product.
If you are working to a fixed specification, or reproducing a formula across production runs, tell us — we can advise on which materials in your palette are likely to move and by how much.
Request a document
Certificates of Analysis and allergen statements are supplied on request for any material we sell. Contact us with the material name and the lot number printed on your bottle, and we will send the documents for that lot.
