Should I Validate a New Fragrance Oil in My Highest-Selling Wax and Wick Combination Before Purchasing 25 Kg?
Share
How much does 25 kg of Dark Vanilla Oud cost from CSI? No pack above 1 kg is listed: 25 × ₹5,691.00 = ₹142,275.00 at the 1 kg price, or ask for a WhatsApp quote. No bulk discount is published.
How long should the ageing test run? At least as long as the 25 kg will take to use plus the time finished candles sit before sale. Your own sales rate sets that.
Is there a step between sample and 25 kg? Yes. A 1 kg pilot batch makes 62 candles of 200 g at 8% and tests the oil at production scale.
Yes — validate in the system that earns your money
Your highest-selling wax-and-wick combination is the system you understand best and the one where a failure costs most. It is the right place to validate a new fragrance oil before a 25 kg commitment, for two reasons. First, the oil will spend most of its life there, so that is where its behaviour matters. Second, keeping everything else identical means any change you see is caused by the oil, not by a new jar or a different wick.
The worked example: the reader's bestseller is a 200 g candle in CSI 464, poured into the 200 ml matte glass jar, with an Eco C1 wick, at 8% fragrance — so 184 g wax and 16 g oil. The new oil under consideration is Dark Vanilla Oud, and the proposal is 25 kg. CSI lists no oil pack above 1 kg, so 25 kg means 25 × ₹5,691.00 = ₹142,275.00 at the listed 1 kg price, or a quote on WhatsApp. No bulk discount is published; do not assume one.
A 100 g sample costs ₹590.00. That is ₹590.00 ÷ ₹142,275.00, about 0.41% of the 25 kg spend, and at 16 g per candle it makes six test candles with a little left over for a strip reference.
What the validation has to prove
A new oil can fail in your bestseller in ways that have nothing to do with how it smells in the bottle. It can need a different wick because it changes how the wax burns. It can colour the wax. It can throw well hot and poorly cold, or the reverse. It can smell right on day three and different on day sixty. The validation is built to catch each of those before 25 kg arrives.
| Parameter | Bestseller standard | Pass rule (suggested) | Result |
|---|---|---|---|
| Wax / jar / wick | CSI 464 · 200 ml matte jar · Eco C1 | Unchanged — this is the point | — |
| Load | 8% of total weight (16 g in 200 g) | Within the page's stated 6–10% range | — |
| Add temperature | Your standard | Below the oil's published flashpoint (not published on this page — ask CSI) | — |
| Cure before first assessment | Page's stated soy minimum, 48–72 h | Then reassess at later points you choose | — |
| Cold throw | Your bestseller oil at the same age | Equal or better in blind comparison | — |
| Hot throw | Your bestseller oil, matched burn | Fills the test room comparably | — |
| Melt pool and flame | Your bestseller behaviour | No tunnelling, soot or oversized flame | — |
| Wax colour | Your bestseller appearance | Any change is acceptable to you and your customers | — |
| Aged check | Same candles after your holding period | Still meets your standard against a fresh reference | — |
A staged route from 100 g to 25 kg
The first stage, costed at CSI's listed prices, uses nine jars in all: six new-oil candles, two current-oil comparison candles and one unscented control. Wax is 9 × 184 g = 1,656 g, and 1,656 × ₹0.5074 = ₹840.25. Jars are 9 × ₹70.80 = ₹637.20 and wicks 9 × ₹5.90 = ₹53.10. With the ₹590.00 sample, the stage costs ₹840.25 + ₹637.20 + ₹53.10 + ₹590.00 = ₹2,120.55, excluding the current oil you already hold, packaging, labour, shipping and GST.
Add a warm-storage comparison if your stock runs hot
If your warehouse or stockists sit in non-AC premises, add a side-by-side heat check: one new-oil and one current-oil candle held together in a controlled warm room or cabinet with a thermometer, supervised, at a temperature and duration you choose — for example 35°C for 14 days as a starting point. Never use a kitchen oven, a stove or a car boot. The result compares the two oils under stress; it does not predict a shelf life.
How long 25 kg will last — and why that sets the test length
At 16 g per candle, 25 kg makes 25,000 ÷ 16 = 1,562 candles (rounding down). How long that lasts depends on your own sales. If, as an example, this scent sells 400 candles a month, 1,562 ÷ 400 = about 3.9 months of oil. The last of that oil will be poured nearly four months after it arrives, and those candles may then sit with you and with stockists for months more.
| Example sales of this scent | Oil per month | Months to use 25 kg |
|---|---|---|
| 200 candles a month | 200 × 16 g = 3,200 g | 25,000 ÷ 3,200 = 7.8 |
| 400 candles a month | 400 × 16 g = 6,400 g | 25,000 ÷ 6,400 = 3.9 |
| 800 candles a month | 800 × 16 g = 12,800 g | 25,000 ÷ 12,800 = 2.0 |
This is why validation includes ageing and not just a first burn. If your aged checks have only reached day 30, you have no evidence for oil poured in month four or candles sold in month eight. CSI's oil pages publish no shelf life or storage conditions for Dark Vanilla Oud or any oil, so before ordering 25 kg, ask on WhatsApp (+91 7397976926) for the IFRA certificate, MSDS and storage guidance for the lot you would receive, and get it in writing. The 60-month shelf life on the CSI 464 page describes the wax, not your fragrance.
What about your other wax and wick combinations?
Validating in the bestseller does not validate everything. If the oil will also go into a coconut-soy line or a larger jar with a different wick, each of those is its own system. You can stage it: approve the bestseller first and commit only the quantity that the bestseller will use, then validate the other combinations from the same lot before extending the order.
The broader principle is simple and runs against a quick sale: the size of the order should follow the evidence, not the other way round. Six candles from a ₹590.00 sample, a 62-candle pilot from a ₹5,691.00 pack, and an ageing record that covers the time the oil will really sit — then 25 kg, if the numbers still say so.

CANDLEMAKINGSUPPLIESINDIA supplies raw materials and production equipment, not finished candles. This guide separates general fragrance-ageing practice from what CSI's own product pages state, says plainly that CSI's oil pages publish no shelf life, storage temperature or ageing data, treats the 60-month shelf life on the CSI 464 and 468 pages as a wax statement only, and labels every test day, cabinet temperature, candle count, reject rate or lead time as a starting point or the reader's own figure.
Prices are live CSI prices from October 2026; product pages are authoritative. No fragrance-oil pack above 1 kg is listed, so larger quantities are shown as multiples of the 1 kg price; ask for a quote rather than assuming a discount.

Assumptions: Fragrance load is a percentage of total candle weight (200 g = 184 g wax + 16 g oil at 8%). CSI fragrance-oil pages publish no shelf life, storage temperature or ageing data; the 60-month shelf life on the CSI 464 and 468 pages refers to the wax. Accelerated heat or cycling tests compare options and do not predict an exact shelf life. Every test day, temperature, candle count, reject rate, lead time and cost of money is a suggested starting point or the reader's own figure. No fragrance-oil pack above 1 kg is listed; larger quantities are shown at the 1 kg price and quoted on WhatsApp. Fragrance-oil prices re-checked 8 October 2026, wax prices 7 October 2026; product pages are authoritative.
