How to Test Fragrance Oil Compatibility Before Buying 1 Kg or 5 Kg
Aktie
What is the warm-storage check? From day 3 to day 10 the warm set sits in the warmest realistic place your candles will meet, then comes back to room temperature. Oil the wax was only just holding tends to show during that cycle.
What changes for 5 kg? Add a second warm cycle (day 14 to 17) and a final look, and decide on day 21. CSI's largest listed oil size is 1 kg, so 5 kg is five 1 kg packs or a WhatsApp quote.
What does it cost? The protocol uses 87 g of oil, so buy 100 g, not 50 g. For one oil (Roasted Coffee), materials consumed come to ₹1,882.85; for two oils, ₹3,504.22.

Why a two-week test, when a candle looks fine on day 1
A candle that looks perfect the morning after pouring has told you very little about a 1 kg order. Oil that the wax is only just holding at room temperature can stay invisible for days, then show as beads, a film or wet patches after a warm spell and a cool night. The failures that cost money in bulk are exactly these slow ones: a batch that looks good at dispatch and arrives oily, a range that behaves in the monsoon and sweats in May. This protocol is built to bring those failures forward to day 11, on nine candles, before the kilogram is on your shelf.
It is one piece of a larger decision. The full 1 kg gate, covering burn, cure, wick, discolouration, cost per candle and stock depth, is What Should I Test Before Buying 1 Kg of a New Candle Fragrance Oil?; the 5 kg gate, with repeat batches and second-order consistency, is What Tests Should I Run Before Ordering 5 Kg of a Candle Fragrance Oil?. This page owns the stability part of both: does the oil stay in your wax, at your loads, through your temperatures, over two to three weeks. If you only want a first read on whether an oil suits soy at all, the shorter three-candle test in How Do I Know If a Fragrance Oil Is Compatible With Soy Wax? comes first; this protocol is for an oil you already like and are about to buy in quantity.
The nine-candle design, and what each candle isolates
Every candle differs from its comparison candle in exactly one way. The reference is candle 2, 8% poured at the middle of your wax page's range and kept cool. Loads follow the lower-of-two-ceilings rule: for most oils in CSI 464 that caps you at 10%; for an oil whose page tops out at 9% (Mahogany Teakwood, Coffee Vanilla Tobacco), replace 10% with 9% throughout.
| # | Load | Oil + wax | Pour temperature (CSI 464 page: 80°C–90°C) | Storage | Compared with | Isolates |
|---|---|---|---|---|---|---|
| 1 | 6% | 9 g + 141 g | Middle, 85°C | Cool | 2 | Load, downward |
| 2 | 8% | 12 g + 138 g | Middle, 85°C | Cool | — | The reference |
| 3 | 10% | 15 g + 135 g | Middle, 85°C | Cool | 2 | Load, up to the ceiling |
| 4 | 8% | 12 g + 138 g | Low end, 80°C | Cool | 2 | Pour temperature, low |
| 5 | 8% | 12 g + 138 g | High end (see the jar note) | Cool | 2 | Pour temperature, high |
| 6 | 8% | 12 g + 138 g | Middle, 85°C | Warm cycle | 2 | Storage heat at the working load |
| 7 | 10% | 15 g + 135 g | Middle, 85°C | Warm cycle | 3 and 6 | Storage heat at the ceiling |
| 8 | none | 150 g wax | Middle, 85°C | Cool | all cool | The wax on its own |
| 9 | none | 150 g wax | Middle, 85°C | Warm cycle | 6 and 7 | The wax on its own, in heat |
Grams. Oil: 9 + 12 + 15 + 12 + 12 + 12 + 15 = 87 g per oil. Wax: 963 g for the seven oil candles plus 300 g for the two controls, 1263 g for one oil. Testing two oils from the same melt shares the controls: 16 candles, 174 g of oil, 2226 g of wax. Pour all candles on the same day from the same wax lot, with the same wick, jar, stir time and cooling spot, or the comparison is lost.
Temperatures: the pour range and the warm spot
The pour range, from your wax page
Candles 4 and 5 check whether the oil stays put across the whole range your wax page allows, because a production day never hits the middle every time. Use the figures on your wax page, read on a thermometer at the moment the oil goes in and at the pour, and never invent a range where a page gives none.
| Wax | Page wording | Candle 4 (low) | Candle 2 (middle) | Candle 5 (high) |
|---|---|---|---|---|
| Luxury Soy Wax CSI 464 | Pour temperature 80°C–90°C; load up to 10% | 80°C | 85°C, or 82°C in the 150 g clear jar | 90°C, or 85°C in the 150 g clear jar ("Safe for hot pour up to 85°C"), so candle 5 still differs from candle 2 |
| Premium Coconut Soy Wax CSI 468 | Pour temperature 58°C–60°C; melting point 50°C–53°C; up to 13% | 58°C | 59°C | 60°C |
| Eco Soy CSI 400 | Add fragrance at 85°C, stir gently for 2 minutes; table: 80 to 90 degrees | 80°C | 85°C | 90°C (jar permitting) |
| Luxury Soy Wax Chunks and waxes with no stated figure | No temperatures in the text we hold | Skip candles 4 and 5, pour candle 2 at the figure your wax maker gives you, and ask us on WhatsApp for CSI waxes | ||
CSI 468's range is only two degrees wide, so candles 4 and 5 there are a test of your thermometer as much as the oil. If 4 or 5 fails and 2 passes, the oil is sensitive to your process: buy the kilogram only if you can hold the middle of the range every production day.
The warm spot
Candles 6, 7 and 9 go to the warmest place your candles will realistically meet: a room without air-conditioning on a warm afternoon, a stock cupboard against a sun-facing wall, the shelf nearest your shop window. Never near a stove, heater or flame, not in direct sun through glass, and always well below the melting point your wax page states (CSI 468: 50°C–53°C). Eco Soy CSI 400's page table lists "Melt Point 100°F (37.8°C)"; we quote that exactly as written and draw no advice from it, so if you pour in that wax, ask us on WhatsApp before choosing a warm spot. Write down where the warm spot is and, if you can, its temperature on each warm day. The warm set comes back to room temperature on day 10 and is read on day 11, because oil the wax cannot hold often appears as the candle cools, not while it is warm.
The schedule, day by day
Each look is the same routine, so scores are comparable across days: same light (a window or a lamp at a low angle), same order along the row, a white tissue pressed lightly on each surface, and one photograph of all nine together. Score before you check the labels on the bases.
The pass/fail sheet
Score each candle at each look on the tissue press: 0 dry tissue, 1 a faint mark, 2 a clear oily mark, 3 film or beads visible without a tissue. Then note three visual checks against the matching unscented control: wet-looking patches at the glass, mottling or frosting, and colour. Colour is noted, not judged here; the method for that is How to Test Fragrance Oil for Discoloration Before Bulk Production.
| Check | Candles | Pass | Conditional | Fail |
|---|---|---|---|---|
| Surface, cool | 1, 2, 3 | 0 or 1 at every look for your intended load | Passes at 6% only: use 6% if it throws well enough | 2 or 3 at 6% |
| Pour-temperature range | 4, 5 vs 2 | Within 1 point of candle 2 at every look | One end fails: hold the middle of the range in production | Both ends fail while 2 passes: the process window is too narrow for bulk |
| Warm cycle, working load | 6 vs 2 | 0 or 1 on day 11 (and day 18 for 5 kg) | 2 on day 11, 0 or 1 by day 14: store cool and re-run before 5 kg | 2 or 3 on day 11 that persists |
| Warm cycle, ceiling | 7 vs 3 and 6 | 0 or 1 on day 11 | Fails at 10%, passes at 8%: cap production at 8% | Fails at both 8% and 10% warm |
| Wet spots, frosting vs control | 1–7 vs 8, 9 | No worse than the control | Slightly worse, surface dry: judgement, and re-run | Clearly worse with oily tissue |
| Controls themselves | 8, 9 | Dry at every look | — | Control fails: the wax or the storage, not the oil. Stop and investigate |
| Result | 1 kg (day 14) | 5 kg (day 21) |
|---|---|---|
| Pass at 8% and 10%, cool and warm | Buy the 1 kg; production at 8% leaves margin | Run the second warm cycle; if it holds, buy five 1 kg or ask for a quote |
| Pass at 8%, warm fail at 10% | Buy, and write 8% as the maximum on your recipe card | Only at 8%, after day 21 |
| Pass at 6% only | Buy only if 6% throws well enough for you (burn test it first) | Not yet; re-run the protocol at 6% and 7% |
| Controls fail | Buy nothing; fix wax or storage | Buy nothing |
| Fails at every load | Do not buy; sample a replacement at 100 g and run it the same way | Do not buy |
What it costs, against what it protects
Materials consumed, valued at CSI prices on 25 September 2026 (wax as CSI 464 at ₹0.51 per gram, jars at ₹94.40 each from either pack, Eco C1 wicks at ₹5.90 each from either pack), excluding labour, freight, packaging and GST.
| Item | One oil (9 candles) | Two oils (16 candles) |
|---|---|---|
| Oil | 87 g Roasted Coffee from a 100 g (₹390.00 bought): ₹339.30 | 87 g Roasted Coffee + 87 g Blue Ocean: ₹769.95 |
| Wax, CSI 464 | 1263 g: ₹640.85 | 2226 g: ₹1,129.47 |
| Jars, 150 g clear | 9: ₹849.60 | 16: ₹1,510.40 |
| Wicks, Eco C1 | 9: ₹53.10 | 16: ₹94.40 |
| Materials consumed | ₹1,882.85 | ₹3,504.22 |
| New cash if you own no oil, jars, wicks or wax (tools extra) | ₹3,930.00 (oil, jar pack of 10, C1 pack of 10, 5 kg wax) | ₹5,428.00 (two oils, jar pack of 20, C1 pack of 20, 5 kg wax) |
Against what it protects: a Roasted Coffee 1 kg is ₹3,738.00, and the one-oil protocol (the 100 g bought plus the wax, jars and wicks consumed, ₹1,933.55) is about 52% of that; wash and reuse the jars and the real outlay falls by 44%. Five 1 kg packs are ₹18,690.00, and the protocol is 10.3% of it. Five 1 kg packs of Blue Ocean are ₹24,780.00; of Honeydew Melon, ₹16,992.00. CSI's largest listed oil size is 1 kg, so "5 kg" means five of those or a bulk quote on WhatsApp; the protocol result is what you send with the request. We sell the kilogram. We would still rather you ran nine candles first.
What to buy for the protocol
Two oils worth putting through it (a dense gourmand and a light aquatic, poured from the same melt), one oil whose page states no candle load, to show how the protocol handles that, and the jar and wax that make the comparison fair. The oils are chosen as protocol candidates on stated load, notes structure, price per gram at 100 g and 1 kg, and stock on 25 September 2026; CSI has no measured stability or throw data for any of them. Candle counts assume 150 g at 8%.

CandleMakingSuppliesIndia sells the oils, jars and wax on this page in 1 kg and larger quantities, and does not sell finished candles. We have told you to buy 100 g first, to wait two weeks, and to walk away from the kilogram if the sheet fails, including from our own oils.
Every price and per-gram figure was verified on CSI's live store on 25 September 2026; every size on the cards is in stock on that date. Loads, cure times, temperatures, the jar's hot-pour figure and the vanillin statement are quoted from product pages; where a page is silent, as Honeydew Melon's is on candle load, we say so.
The nine-candle design, the warm-cycle schedule, the scoring and the pass/fail rules are editorial judgement; CSI has no measured stability, compatibility or throw data for any oil.

Non-price figures: candle maths assume a 150 g candle with load as a percentage of total weight (6% = 9 g oil + 141 g wax, 8% = 12 g + 138 g, 10% = 15 g + 135 g); candle counts are floor(grams ÷ 12). Wax temperatures and ceilings are quoted from wax pages as written and are formulation limits, not regulatory limits; the jar's "Safe for hot pour up to 85°C" is its page wording. The day schedule, warm-spot guidance, scores and pass/fail rules are editorial judgement; costs are worked examples excluding labour, freight, packaging and GST.
