How to Check Whether a Fragrance Oil Is Candle-Safe
Aktie
What should I ask the supplier for? The SDS, the IFRA documentation, and confirmation of the stated applications for that specific product. CSI supplies documentation on request on WhatsApp — only 2 of our 107 oil pages even mention an SDS, which is exactly why asking is a step and not an afterthought.
Can the page alone settle it? No. A page can tell you what an oil is intended for and what it contains. Only a cured burn in your jar, on your wick, at your load can tell you how it behaves.
What does skipping it cost? A 500-candle run in Chunks and a mid-priced oil is ₹1,10,129.80 of wax and oil. The check is 0.42% of that.
Five gates and five stop rules
Most makers do this backwards: buy 500 g, pour a hundred candles, then start reading. Each gate below is far cheaper than the one after it, and the stop rule matters as much as the step — a gate you never fail is a gate you are not really running.
| Gate | What you do | Time & cost | Stop rule |
|---|---|---|---|
| 1 · Read | Eight fields off the listing, written on one line each, blanks included | 4 minutes · free | Your format is not named in the stated applications, or the page contradicts itself |
| 2 · Ask | One message naming the product: SDS, IFRA documentation, and anything the page left blank | 20 minutes · free | You cannot get an answer either way. "Nothing exists for that product" is an answer you can work with; silence is not |
| 3 · Melt | Look through the melt at the wax's stated add temperature, after the stated stir — either inside the batch you are about to pour, or as a standalone 100 g trial | 20 minutes · free inside the batch, ₹124.71 as a separate 100 g melt | It will not go clear at the stated temperature, or droplets ride the surface |
| 4 · Surface | One jar wiped at 24 hours, then again at 72 | 3 days · one jar | The second tissue comes away oily — the first can be anything |
| 5 · Burn | Cured jar at day 14: time to full pool, throw at 30 and 120 minutes, soot, mushrooming, top after cooling. Repeat with a second jar | 14 days · four jars total, ₹463.93 | No full pool in three hours, visible soot, a drowning wick, or a top you would not sell |
Gate 2 deserves a word, because makers hesitate over it. Asking a supplier for documentation is routine — the same conversation as asking for a GST invoice. And an honest "no document exists for that product" is useful: it tells you the oil has to be carried entirely on gates 3 to 5, and you can decide whether that is acceptable for a line you sell.
Gate 1: eight fields, and what a blank means
Read the listing with a pen. You are not looking for reassurance — you are building a list of what nobody has told you yet. Here is the field set with the action for each blank, because a blank is not a defect in the oil: it is a task on your card.
| Field | Stated on | What it tells you | If blank |
|---|---|---|---|
| Stated applications | 91 of 107 · candles named on 85 | What the supplier intends the oil for. The single most important line | Stop and ask. Do not infer it from the scent name |
| Candle load % | 74 of 107 | The oil's own ceiling, which you compare with your wax's | Use the wax's figure alone, start low, and say on your card that the oil's is unknown |
| Cure time | 62 of 107 | The page's minimum before judging — usually 48–72 hours for soy | Use the series convention of 14–21 days for soy containers. Longer is never wrong |
| Flash point | 18 measured · 32 give only the "> 93°C" template line · 56 state nothing | A handling and transport classification. Never a burn-off temperature | Ask for the SDS figure. Never estimate it or borrow one from a similar scent |
| Vanillin / discolouration | 61 of 107 · 18 give a number | Whether pale wax is likely to brown | Pour one pale jar and watch it to day 30 before committing a collection |
| Scent notes or profile | 102 of 107 · 88 with a full pyramid | Rough guide to which part of the scent is most volatile | Sample 15 g and describe it yourself, in writing, before and after cure |
| IFRA wording | 71 of 107 mention IFRA · 0 publish a number, amendment or category | That use-level standards exist for the material. Nothing about throw | Request the documentation. Never treat a phrase on a page as a document in a file |
| Wick guidance | Present on many candle-first listings | A starting family — cotton, eco or wooden — not a size | Start from your vessel diameter and test two sizes |
Two entries in that table are worth pausing on. "Flash point: nothing stated on 56 pages" is the commonest single gap in the range, and it is not a safety scandal — it is a missing line on a listing, and the figure exists on the Safety Data Sheet. And the IFRA row shows why this post has a gate 2 at all: 71 pages mention IFRA and not one publishes a certificate number, an amendment number, a category or a date. A phrase is a phrase. The document is the thing you can send to a stockist, and it arrives by request — see what an IFRA certificate actually is.
Gate 2: the message, word for word
This gate fails most often because the question is too vague. "Is this candle-safe?" invites a yes. Ask instead for named documents about a named product, and what comes back is either a file or a clear no — both of which you can act on.
| Ask for | Why | What it proves | What it does not prove |
|---|---|---|---|
| The SDS for [product name, pack size] | It is the document that carries the measured flash point and handling information | That a datasheet exists and what it states about handling | Nothing about throw, load performance or how it behaves in your wax |
| The IFRA documentation for [product name] | Use-level standards by product category are what an IFRA document addresses | That use-level information exists for the fragrance, and what category rate it names | That your candle will be good, or that the level named is your best-performing load |
| Confirmation of stated applications | 16 pages state none and 22 do not name candles | The supplier's intended use for the product, in writing | Suitability in your specific wax, load and vessel |
| The figure the page left blank | A missing flash point, load or vanillin line is a question with an owner | Either a figure you can quote, or a clear "not available" you can record | Anything about the other seven fields. Ask for each one by name |
One message covers all four. Something like: "Please send the SDS and any IFRA documentation for Sage and Cedarwood Fragrance Oil, 100 g. The listing does not mention IFRA — could you confirm what documentation you hold for it, and confirm the stated applications? I also need a GST invoice." That is the whole gate. CSI handles bulk pricing, GST invoicing, SDS and IFRA documentation on WhatsApp, and the honest shape of the answer is per product: we send what exists for the item you name, and say so plainly when nothing does.
Gates 3–5: the fifteen-day bench run
Four jars, one oil, one wax, one wick, one load. The jars are small on purpose — a 70 g votive costs ₹31.86 and tells you the same things a 200 g jar does about dissolution, surface and pool formation. Here is the run, day by day.
Note what the run does not include: a judgement on day two. A jar at 48 hours can be lit safely and tells you almost nothing about what a customer will experience, which is a distinction worth keeping straight — burning a candle 24 hours after making it covers the difference.
What the check costs, and what skipping it costs
The argument for checking is not caution, it is a ratio. Here is the whole check priced from listed packs, followed by the run it stands in front of.
| Item | Pack | Pack price | Used | Value consumed |
|---|---|---|---|---|
| Luxury Soy Wax Chunks | 1 kg | ₹599 | 257.6 g | ₹154.30 |
| Sage and Cedarwood Fragrance Oil | 50 g | ₹354 | 22.4 g | ₹158.59 |
| Eco Candle Wicks, Thin (C1) | 10 wicks | ₹59 | 4 wicks | ₹23.60 |
| Clear Glass Votive Jar 70 gram | Pack of 10 | ₹318.60 | 4 jars | ₹127.44 |
| The whole check | — | ₹1,330.60 | — | ₹463.93 |
| The run it protects | 500 × 200 g at 8% | 92 kg of wax + 8 kg of oil, from listed packs | ₹1,10,129.80 | |
Put plainly: the complete check costs less than half a percent of the materials in the run it stands in front of, and less than one 200 g candle's worth of wax and oil per test jar. The expensive version of this decision is not the check. It is the fortnight of a hundred customers' opinions that arrives instead.
The file you keep afterwards
One folder per oil, named after the product exactly as the listing names it. Inside: the eight gate-1 fields copied verbatim with the date you read them; whatever gate 2 returned, or a note saying what did not exist; the clarity result; the two wipe results; the day-14 and day-15 burn sheets; and one photograph of the cured jar beside an unscented pour. That is perhaps fifteen minutes of writing spread over the fifteen days.
It earns its keep three ways. A stockist asks what documentation you hold — you send the file instead of promising to look. A batch behaves differently six months on — you compare readings against the old sheet instead of arguing from memory. You reorder after a year — the load, wick and pour reading are on the card. None of it needs software; it needs the check to have produced a record rather than a feeling.
Three listings, three different gaps
Chosen to show what gate 1 looks like when it goes well and when it leaves you work. Per-candle figures use a 200 g candle at 8%: 184 g of wax plus 16 g of oil.
| Size | Price | Per 100g |
|---|---|---|
| 50 gm | ₹354 | ₹708 |
| 100 gm | ₹696.20 | ₹696.20 |
| 500 gm | ₹2,584.20 | ₹516.84 |
| 1 kg | ₹6,867.60 | ₹686.76 |

CANDLEMAKINGSUPPLIESINDIA supplies raw materials; we do not blend the fragrance oils and we do not sell finished candles. A page written purely to sell would tell you that every oil in the range is candle-safe and stop there. Instead this one tells you that 56 of our 107 oil listings publish no flash point, 36 never mention IFRA, 16 state no applications and none publishes an IFRA certificate number — because the gaps are what your check has to cover, and you would find them anyway.
Every field, figure and quotation is reproduced verbatim from the CSI product page for that specific oil or wax, read from live listings in September 2026; every price is the listed variant price on the same date, and the coverage counts are arithmetic across all 107 fragrance-oil pages. The five gates are a protocol: no test result is reported anywhere on this page, because these are tests for you to run in your own wax, and no outcome is claimed or predicted. Stated loads and cure windows are formulation guidance from the pages, not regulatory limits. No legal, regulatory or safety-standard claim is made, and nothing here replaces the Safety Data Sheet for the oil you are using.
Gate 2 is a real service, not a rhetorical device: message CSI on WhatsApp at +91 7397976926 with a product name and we will send the SDS and IFRA documentation we hold for it, along with GST invoicing and bulk pricing above the listed packs. Where nothing exists for a product, we say so rather than sending something for a different one.

Figures verified September 2026: Coverage across the 107 CSI fragrance-oil pages — applications stated on 91 (candles named on 85, so 22 do not name them, and 16 state none); candle usage percentage on 74; a cure time on 62; a measured flash point on 18, with 32 stating only the template line "Flash point > 93°C (suitable for alcohol-based products)" and 56 stating none; a vanillin or discolouration statement on 61 (18 numeric); scent notes or a profile on 102, a full pyramid on 88; IFRA mentioned on 71 and never mentioned on 36; an SDS mentioned on 2; and zero pages publishing an IFRA certificate number, amendment number, category or assessment date. Zero pages state a shelf life or storage instruction, so no storage or shelf-life advice is given here. One page's copy calls its 203°C figure the highest in the range while another CSI page states 206°C; that contradiction is described, and neither superlative is repeated as fact. Verbatim page text — Sage and Cedarwood "Flashpoint: 190°C", "Up to 10% for soy wax", "Up to 6% for paraffin wax", "Cure Time: 48–72 hours for soy wax", "Vanillin Content: 0% (No risk of discoloration)", "Works well with soy, paraffin, coconut, and blended waxes", "Cotton or wooden wicks for a steady burn", "Main Aroma: Herbaceous sage with warm, woody cedar undertones", "Ideal for container candles, pillar candles, and wax melts", and no mention of IFRA; Citronella "Flash Point: 270°F", "Vanillin Content: 0%", "Phthalate-Free: Yes", "Top: Lemon, Lemongrass- Middle: Citronella, Green Herb- Base: Wood", "Follow IFRA guidelines for skin safety", and no candle load percentage; Mango Coconut "Candle usage rate 6-10% of total wax weight", "Wax melt usage rate 10-15% of total wax weight", "Suitable for candles, wax melts, reed diffusers, room sprays, and body products", "Test with your specific blend before full production runs", and no flash point, vanillin statement or note pyramid; Luxury Soy Wax Chunks "Recommended fragrance add temp 80-90°C", "Pour at 70-80°C into your prepared containers with wicks in place", "Allow candles to cure for a minimum of 48 hours (ideally 1-2 weeks) before performing burn tests". Vessel limit: "Safe for hot-pour up to 85°C" appears on seven CSI jar pages. Prices used: Sage and Cedarwood 50 g ₹354 (₹7.08/g) · 100 g ₹696.20 · 1 kg ₹6,867.60; Citronella 15 g ₹141.60 · 100 g ₹767; Mango Coconut 15 g ₹93.22 · 100 g ₹500; Luxury Soy Wax Chunks 500 g ₹299 · 1 kg ₹599 (₹0.599/g) · 10 kg ₹5,999; Eco Candle Wicks Thin (C1) 10 for ₹59 (₹5.90 each); Clear Glass Votive Jar 70 gram Pack of 10 ₹318.60 (₹31.86 each). Check arithmetic: 4 × 70 g = 280 g finished; at 8%, oil 22.4 g and wax 257.6 g; per jar 5.6 g + 64.4 g; wax 257.6 × ₹0.599 = ₹154.30; oil 22.4 × ₹7.08 = ₹158.59; wicks 4 × ₹5.90 = ₹23.60; jars 4 × ₹31.86 = ₹127.44; consumed ₹463.93 and ₹463.93 ÷ 4 = ₹115.98 a jar; packs ₹599 + ₹354 + ₹59 + ₹318.60 = ₹1,330.60. The clarity check uses a 100 g melt: at 10% that is 90 g of wax and 10 g of oil, so 90 × ₹0.599 = ₹53.91 plus 10 × ₹7.08 = ₹70.80, or ₹124.71. Run arithmetic: 500 × 200 g at 8% = 8 kg of oil and 92 kg of wax; 25 kg and 100 kg wax packs are not listed, so 92 kg = 9 × ₹5,999 (₹53,991) + 2 × ₹599 (₹1,198) = ₹55,189; 8 × ₹6,867.60 = ₹54,940.80; total ₹1,10,129.80, or ₹220.26 a candle for wax and oil alone; ₹463.93 ÷ ₹1,10,129.80 = 0.42%. Load convention: a share of the finished candle, so 200 g at 8% = 184 g wax + 16 g oil; the Chunks page phrases its own load "of total wax weight", a different basis worth noting when comparing figures with another maker. Per-candle oil cost at 8% = 16 g × the 100 g price per gram: Sage and Cedarwood ₹111.39, Citronella ₹122.72, Mango Coconut ₹80.
