Judging Lilac Oil: Which Papers Matter for Your Project
A bottle of lilac oil does not come with a grade. There is no standard that ranks composed scents from good to better, so the useful question shifts from "how good is this?" to "does this seller's paperwork fit what I plan to make?" A candle maker, a soap maker and someone filling a body-oil bottle each need something different, and it pays to know which.
Start with what you are making
IFRA sorts finished products into categories by how they meet the body. Its guidance for the 51st Amendment puts body creams, oils and lotions in Category 5A, facial moisturizers in 5B, bar soap, shampoo and bath products in Category 9, reed diffuser oils and pot-pourri in 10A, manual air-freshener sprays in 10B, and candles, incense, sachets and plug-ins in Category 12. For candles, skin exposure is expected to be negligible, so the concentration of a fragrance ingredient in the finished candle is not restricted. For leave-on skin products the limits are tighter and depend on what is in the fragrance.
| You are making | IFRA category | Paper worth asking for |
|---|---|---|
| Body oil or lotion | 5A | Allergen information and an IFRA statement; your own patch test |
| Bar soap or bath products | 9 | An IFRA statement for Category 9; allergen information if you sell in the EU |
| Candle or wax melt | 12 | Flash point and safety data sheet |
| Reed diffuser or pot-pourri | 10A | IFRA statement and safety data sheet |
| Room or linen spray | 10B | IFRA statement, safety data sheet, and how it mixes into your base |
What each document promises
A Certificate of Analysis reports measurements made on a lot. A safety data sheet covers hazards and handling. An IFRA Certificate of Conformity is something else again: IFRA's guidance describes it as a document issued by the company that creates the fragrance mixture, confirming that a specific mixture can be used up to a stated concentration in a specified product type, under a named Amendment. The same guidance adds that it "does not replace a safety assessment." So read the scope on any certificate you are handed, because the product type, the maximum percentage and the Amendment number are the parts that matter. If a product is marketed for several uses, the most stringent restriction applies to all of them.
What our own paper shows
We sell one product, Lilac Blossom Oil, and the Certificate of Analysis we publish is for one batch. It lists appearance, smell, relative density (0.973 at 20 C), refractive index (1.501) and optical rotation (-0.72 degrees), each next to its stated range. These are physical measurements, so they are a handy consistency check: if you ask for the figures on your own lot, you can see whether it sits in the same window as the first bottle. They do not list ingredients, and the sheet does not say which pharmacopoeia it refers to, so we would not offer it as proof of identity or quality. For anything beyond that, such as a flash point, safety data sheet, IFRA statement or allergen information, ask us in writing through the contact page before ordering and keep the reply. Our worked example of reading a COA and SDS shows what each line is for.
If you sell in Europe
The European Commission describes an amendment adding 56 further fragrance allergens to individual labelling, required above 0.001% in leave-on products and 0.01% in rinse-off products, with new products covered from 31 July 2026 and products already on the market by 31 July 2028. A maker who must print those names needs the supplier to tell them what is in the scent at that level, so make that request in writing, and wait for the answer before buying in volume.
In the United States
FDA says a label may simply say "fragrance" and that the labeling law cannot be used to force a company to reveal trade secrets. It also says that a firm putting its name on a cosmetic is responsible for the product's safety and labeling, and must have adequate substantiation of safety. In other words, a supplier's silence on contents does not move your responsibility elsewhere. If you plan to sell, a regulatory consultant or cosmetics attorney is the person to settle the details.
Write one clear request
A vague email gets a vague answer, so it is worth ten minutes to write a good one. Whoever you are writing to, ours included, a short request is easier to answer and easier to file. Include these points:
- What you are making, in one sentence, such as "a leave-on body oil" or "a soy container candle".
- The IFRA category you think it falls in, and where you plan to sell it.
- The exact documents you need, named one by one.
- The size you are considering and the lot number, if you already have a bottle.
- A request that the reply come in writing.
Keep the reply in the same folder as your recipe and your test notes. Months later, when someone asks what went into a batch, that folder is the difference between a quick answer and a long afternoon of searching.
A short routine before you commit
Name your product and its IFRA category. Ask the seller, in writing, for the paper that category needs. If the reply is a certificate, read its scope. Then buy the smallest size and run a weighed trial, following our staged plan for testing before bulk. Only then compare sizes. If you are weighing us against a fragrance oil, our comparison of fragrance oil and crafted lilac oil and the shopper's checklist cover the rest.
Paperwork is not the glamorous side of a lovely scent, but it is the side that lets you enjoy the rest with a clear head.
