I’m Moving From 100 g Fragrance Samples to 5 Kg Commercial Orders — What Should Change in My Raw-Material Approval Process?

A sample approval and a supply approval are different things

When you test a 100 g sample, the question is simple: does this fragrance work in my candle? When you order 5 kg, the question becomes: will every gram of what arrives behave like the 100 g I liked, and will I be able to prove it if it does not? Most makers keep the same informal routine for both. That is where commercial fragrance problems start.

Take Bergamot Amber as a worked example. The 100 g bottle costs ₹560.00. At this series' convention of a 200 g candle at 8% load (16 g of oil), it makes 100 ÷ 16 = 6 candles, with a little left over. Five 1 kg bottles cost 5 × ₹5,437.00 = ₹27,185.00 and make 5,000 ÷ 16 = 312 candles. The oil also gets cheaper per gram — ₹560.00 ÷ 100 = ₹5.60 per gram in the 100 g size against ₹5,437.00 ÷ 1,000 = ₹5.44 per gram (rounded) in the 1 kg size — which is exactly why people scale up. The saving is modest per candle; the commitment is not. But 312 candles is several months of stock for many small businesses, and that changes what your approval has to cover.

Write the approval down before the bulk order

The single biggest change is turning "I liked it" into a document. The approval standard for a fragrance is a short page that says: this oil, at this load, in this wax, in this jar, with this wick, cured for this long, gave this result. If you cannot write it down, you have not actually approved anything — you have enjoyed a sample.

Load deserves particular care. Bergamot Amber's product page carries its own intensity guide: at 6% the bergamot leads, at 8% it is balanced, and at 10% the amber comes forward and the vanilla and musk base becomes more prominent. So "approved Bergamot Amber" means little on its own. "Approved Bergamot Amber at 8% of total candle weight in CSI 464, 48–72 hours minimum cure" is something you can check a new bottle against.

Keep a retained portion of the approved sample, if any is left, or of the first bulk bottle once it passes. About 20 ml in a small, well-filled, tightly capped amber glass bottle is a sensible suggested starting point. Label it with supplier, product, invoice number, date received and the phrase "approval reference". This is the benchmark every future 1 kg bottle gets sniffed against.

Three gates between the courier and your production pour

A commercial approval process has gates. Material moves forward only when the previous gate is signed. For a 5 kg fragrance order, three gates are enough for most small businesses.

Gate 3 is where many makers want to cut corners, and there is a fair argument for a lighter version. If every bottle passes Gate 2 cleanly and you already have a proven formula, two or three confirmation candles cured for the stated time on the product page, then burned beside a retained candle from your sample testing, answer the question. You do not need to repeat the full wick ladder you ran at sample stage. What you should not do is skip Gate 3 entirely and discover a mismatch in candle 200.

Documents, storage and who signs

CSI's product pages state that its oils are IFRA certified and that IFRA and MSDS documents are available on WhatsApp request (+91 7397976926). At sample stage few makers bother. At 5 kg, request them before or with the order and file them with the invoice. If you sell to retailers or corporate buyers, they may ask for these documents, and "I'll find it" is a poor answer when a shipment is waiting.

CSI's pages do not publish lot numbers or certificates of analysis for oils, and you should not assume either will arrive. Your own record carries that job instead: invoice number, date received, bottle count, and your own lot code written on every bottle.

Storage changes too. A 100 g sample is gone in a week. Five 1 kg bottles may last months, and fragrance oils do not enjoy heat, light or air. Keep bottles tightly capped, upright, away from windows and away from the melting area. Open one bottle at a time rather than all five, so that four stay sealed and full while you work through the first. Write the opening date on each. If a bottle has been open for a long time and your next production run is large, a quick strip comparison against the sealed reference before that run costs five minutes and settles any doubt.

Finally, name the person who signs the release. In a one-person business that is you, and the signature still matters: it forces you to look at the Gate 2 and Gate 3 records before pouring. In a small team, it stops the situation where everyone assumed someone else had checked.

When the bulk does not match the sample

Sometimes it will not match, and the reasons are not always sinister. Natural materials in a blend can vary. Oil that travelled in a hot vehicle can smell sharper for a day or two. A sample may have come from an earlier production run than the bulk. Your job at goods-in is not to explain the difference. It is to decide whether the difference reaches the finished candle.

If Gate 2 shows a slight difference but Gate 3 candles meet your standard, record the observation and release. If Gate 3 candles fall short — weaker hot throw at the same load, a different character, a colour shift you cannot sell — the oil stays in quarantine. Send the supplier your notes and photographs and ask what changed. That applies to oils bought from us exactly as it applies to anyone else's.

What you must not do is raise the load quietly to compensate, or top up an approved bottle with the questionable one. Either move turns a supplier question into a formula change you have not tested — and at 312 candles, an untested formula change is the most expensive shortcut in the building.
