I Want to Ship Soy Candles to Rajasthan During Summer — What Heat-Stability Testing Should I Do Before Approving a Wax?
शेयर करना
Why test the box on its side? A softened candle can tilt its surface and lean its wick when laid over, then set that way. The side arm catches it.
Is looking fine after the cycles enough? No. Burn one cycled candle beside its control; a shifted wick shows in the burn, not the photo. See the sheet.
What does it cost? ₹5,383.46 in CSI materials for 16 candles across CSI 468 and Soy Pearl. See the kit.
Test the cycles, not just the peak — and test the box on its side
A heat test that holds candles at one high temperature for a few hours is a reasonable first screen. For a long summer route into Rajasthan it is not enough to approve a wax, for two reasons. The first is time: a parcel can spend several days on the road and in hubs, and general climate knowledge tells you that north-west India's May–June heat combines hot days with nights that are cooler but not cool. Each day the candle warms and softens a little; each night it partly sets again. That repeated cycle is a different stress from one peak, and it is the stress the route actually applies. The second is handling: a candle that has softened in the afternoon is more vulnerable to whatever the parcel does next, including being laid on its side.
So the approval test on this page has three arms. A control arm stays packed in the workshop. A cycled upright arm repeats your logged day–night profile for the number of cycles your logs show. A cycled on its side arm runs the same cycles with the box tipped over, because a candle that only stays perfect when it travels upright has not been approved for a courier network. Each wax is tested unscented and at 8% in the arms where it matters, and every exposed candle is judged and then burned against its control twin.
The waxes here are Premium Coconut Soy Wax CSI 468 and Natural Soy Pearl Wax. CSI's product page for CSI 468 states a melting point of 50–53°C; Soy Pearl publishes no melting point, temperatures, ceiling or shelf life. Neither page — and nothing CSI publishes — says how either behaves over days of summer cycling. That is precisely what this test is for. Your logger's numbers set the cycles; no number on this page claims any wax survives any temperature.
Turning your logger trace into a test profile
Send two or three logged parcels on the route in the season you care about — production packing, a min/max thermometer or small data logger inside (not CSI items; buy locally). From each trace, write down the numbers in the sheet below. The profile you test is the worst of the traces, not the average. If you cannot log in summer because summer has passed, log now, label the result as an off-season profile, and plan a confirmation run next April or May.
| Field | Trace 1 | Trace 2 | Trace 3 | Test profile (worst) |
|---|---|---|---|---|
| Days from dispatch to delivery | ___ | ___ | ___ | ___ |
| Daytime peak inside parcel, each day | ___ / ___ / ___°C | ___ | ___ | ___°C |
| Hours per day above workshop temperature | ___ h | ___ | ___ | ___ h |
| Night low inside parcel | ___°C | ___ | ___ | ___°C |
| Number of warm–cool cycles | ___ | ___ | ___ | ___ |
| Hours at destination before opening | ___ | ___ | ___ | ___ |
| Box orientation on arrival (if known) | ___ | ___ | ___ | Test on its side anyway |
Reproducing a multi-day cycle at home needs a way to hold a warm temperature for the day phase and let it fall for the night phase. A closed car parked in sun with a logger inside reproduces the shape roughly but not the number; a thermostatically controlled box such as an incubator or proofing cabinet reproduces it better. Simulating hot courier conditions compares the options. Do not use a kitchen oven or a heater aimed at candles; both are uneven and a fire risk with fragrance oil. Until your traces arrive, an example day phase of a closed chamber at about 40–45°C for 6 hours, repeated over three days with the box cooling to room temperature overnight, is a labelled provisional profile — replace it with your log.
The approval design: control, cycled upright, cycled on its side
| Approval test | Condition | Candles per wax | Pass rule (write it first) |
|---|---|---|---|
| C · Control | Workshop, packed as shipped, whole test | 1 unscented + 2 at 8% | Reference |
| CU · Cycled upright | Your worst logged profile: ___ cycles, peak ___°C, ___ h per day | 1 unscented + 2 at 8% | After 24 h recovery: no worse than C on surface, blot, glass, wick |
| CS · Cycled on its side | Same cycles, box laid on its side for the whole run | 2 at 8% | No wax on the jar wall or lid; wick within re-centring tolerance; surface level |
| Post-cycle burn | One CU and one CS 8% candle burned beside a C twin | (from above) | Safety: no taller flame, more soot or hotter jar than C |
| Post-cycle shelf | Remaining CU 8% candle 14 days in a non-AC room (example) | (from above) | No late sweating or frosting beyond your standard |
| Total | 8 per wax · 16 for two |
The approval scoring sheet
Score after the 24-hour recovery, then add the burn and the 14-day shelf. CSI publishes no numeric flame-height or jar-temperature limit; the burn rule is no worse than the control on every safety line, within your jar supplier's guidance and the candle fire-safety standard you work to (ASTM F2417 is a commonly cited US standard).
| Line | C | CU (unscented / 8%) | CS (8%) | Pass rule |
|---|---|---|---|---|
| Cycles received | — | ___ cycles, peak ___°C | same | Matches the profile |
| Surface 0–3 | ___ | ___ / ___ | ___ | No worse than C |
| Surface level (CS) | level | — | ___ mm tilt | Within your cosmetic standard |
| Wax on wall or lid | none | ___ | ___ | None |
| Wick lean, mm | ___ | ___ / ___ | ___ | Within re-centring tolerance |
| Blot 0–3 | ___ | ___ / ___ | ___ | 8% no wetter than unscented |
| Glass contact: wet spots, gaps | ___ | ___ / ___ | ___ | No new area beyond standard |
| Burn vs C: flame, soot, jar | ref | ___ | ___ | Safety: no worse than C |
| 14-day shelf blot / frosting | ___ | ___ | — | Within standard |
The priced approval kit
CSI's load convention: oil = 200 g × load. Each wax needs 1,504 g for 8 candles, 1,579.2 g with a 5% pour-loss allowance (a working assumption). The twelve 8% candles need 192 g of Woody Oud, 201.6 g with the allowance.
| Item | Need | Buy | Price |
|---|---|---|---|
| Premium Coconut Soy Wax CSI 468 | 1,579.2 g | 2 × 1 kg | ₹1,300.00 |
| Natural Soy Pearl Wax | 1,579.2 g | 2 × 1 kg | ₹900.00 |
| Woody Oud Fragrance Oil | 201.6 g | 2 × 100 g + 1 × 15 g | ₹999.46 |
| Eco Candle Wicks Thin C1 | 16 + 2 spare | 1 × 20-pack | ₹118.00 |
| White Matte Glass Jar | 16 jars | 4 × 5-pack | ₹1,416.00 |
| Premium Packing Tissue Paper (blot test) | 1 sheet per candle per check | 1 × 100 sheets | ₹650.00 |
| Kit total (logger and test box not included) | ₹5,383.46 |
Both waxes come out at 2 × 1 kg: CSI 468 needs just over 1.5 kg, so a 1 kg and a 500 g bag would fall short and 1 kg + 2 × 500 g costs the same ₹1,300.00 as 2 × 1 kg. Soy Pearl starts at 1 kg. The oil is cheapest as 2 × 100 g + 1 × 15 g (₹999.46).

What a damaged consignment costs, and what approval saves
At production packs (10 kg wax, 1 kg Woody Oud, ₹5.90 wick, ₹70.80 jar; labour, packaging, freight and GST excluded) a 200 g candle at 8% costs ₹266.41 in CSI 468 (₹117.21 of wax) and ₹227.36 in Soy Pearl (₹78.16 of wax). Woody Oud adds ₹72.50 in either.
| Wax | Material in the consignment | Example 10% damaged | Approval kit as share of one consignment |
|---|---|---|---|
| CSI 468 | ₹15,984.43 | ₹1,598.44 | 33.7% |
| Natural Soy Pearl | ₹13,641.74 | ₹1,364.17 | 39.5% |
A single 60-candle consignment carries ₹15,984.43 of material in CSI 468 or ₹13,641.74 in Soy Pearl. If an example one in ten candles arrives damaged, the material alone is ₹1,598.44 or ₹1,364.17 — before return courier, the stockist's patience and any replacement run. The ₹5,383.46 kit is a one-off; the damage repeats every summer consignment until the formula is fixed.
| Item | Need | Buy | Price |
|---|---|---|---|
| CSI 468 (if approved) | 11,592 g | 1 × 10 kg + 2 × 1 kg | ₹7,670.00 |
| Natural Soy Pearl (if approved) | 11,592 g | 1 × 10 kg + 2 × 1 kg | ₹5,148.00 |
| Woody Oud | 1,008 g | 1 × 1 kg + 1 × 15 g | ₹4,624.42 |
The approval rule
| Result | Decision | Purchase |
|---|---|---|
| CU and CS pass every line, burn and shelf included | APPROVED for the logged route and season | Consignment materials above; log one parcel of the first shipment |
| CU passes, CS fails (surface tilt, wall wax, wick lean) | APPROVED WITH PACKING CONDITION | Same wax; change packing to hold the candle upright and firm — 5434 |
| CU passes on looks, fails the burn | NOT APPROVED | Re-match the wick in a separate test, then repeat CU |
| Unscented passes, 8% sweats | NOT YET — load question | Load ladder, then repeat |
| Unscented fails CU | NOT FOR THIS ROUTE in summer | Other wax or formulation — 5422, 5430; or seasonal dispatch — 5437 |
An approval holds for the route, the season, the oil, the load, the jar and the packing it was tested with. Change any of those and the relevant line needs a confirmation run. Testing above workshop temperature for many routes covers how a Rajasthan approval can stand in for milder routes, the hub covers the bulk order, and seasonal qualification puts the confirmation run on your calendar each spring.
CANDLEMAKINGSUPPLIESINDIA supplies raw materials, not finished candles. A summer route into Rajasthan is where a supplier is most tempted to promise heat stability. We publish no heat-survival data for any of our waxes, and CSI 468's published melting point is a pour-planning fact. This page tells you how to approve a wax on your own evidence — including when the fix is packing, not wax.
Every wax price is CSI live pricing, re-checked 1 October 2026; Woody Oud prices are from the 24 September 2026 pull; wick, jar and tissue prices are as verified on 10 September and 24–25 September 2026. Candle splits, per-candle and consignment costs and pack rounding are arithmetic, shown to two decimals. Product-page statements are attributed to CSI's product pages.
The three arms, the illustrative cycle shape, the example provisional profile, candle counts, 24-hour recovery, 14-day shelf, the 60-candle consignment, the 10% damage share and the 5% pour loss are labelled working practices and examples.

Non-price figures and assumptions: CSI convention: load is a share of the finished candle (200 g at 8% = 16 g oil + 184 g wax). CSI publishes no heat-survival, softening or sweating data for any wax. Route temperatures are the reader's own logged readings; chamber, closed-car and cycle conditions are labelled example test conditions, not specifications or claims that any wax survives them. The cycle curve is an illustrative shape with no values. Arms, candle counts, recovery, shelf duration, consignment size, damage share and 5% pour loss are labelled working practices and examples. CSI publishes no flame-height or jar-temperature limits; ASTM F2417 is named only as a commonly cited standard. Material costs exclude labour, packaging, freight and GST.
