I Changed Wax Suppliers and My Previously White Candle Is More Yellow — Could the Base Wax Affect the Finished Colour Enough to Require Colour Reformulation?
How do I tell wax colour from fragrance colour? Pour unscented pucks of old and new wax, then scented pucks with the same oil lot. If the unscented pucks match and the scented ones do not, the oil–wax pairing is the source.
Do I need to reformulate? Only if the colour is part of what you sell. White SKUs may need to stay on the old wax; natural-look SKUs may just need new photos; dyed SKUs need a small dye ladder in the new wax.
Can I make a cream wax whiter? Not with the dyes CSI lists — they add colour, they cannot remove it, and no white dye or UV inhibitor is listed. Choose the base wax by puck instead.
Yes, it can — and a puck test tells you whether it did
When a white candle comes out creamier or more yellow after a wax change, the base wax is a likely suspect, but not the only one. In general candle-making practice, the finished shade of an undyed candle is the sum of several things: the wax's own base colour, any colour the fragrance oil brings or develops in that wax, what heat and time in the melter do, and what light does in storage. Change the wax and you can move the first of those directly — and the second, because an oil can behave differently in a different wax. So yes: the base wax can affect the finished colour enough to matter, and whether it needs a colour reformulation depends on what you are selling.
The honest starting point is that CSI publishes no colour or whiteness figures for any of its waxes, and this page will not claim one CSI wax is whiter or creamier than another. The example uses Luxury Soy Wax CSI 464 as the old wax behind a white candle and Premium Coconut Soy Wax CSI 468 as the new one, not because CSI 468 is known to be yellower — nothing published says so — but because any two waxes might differ, and the test below shows whether yours do. The test separates base colour from oil, light and process, so you reformulate the right thing.
Colour is also the one wax-change result that customers see before they light anything, which makes it commercially urgent even when it is not a safety issue. The wax-change hub puts appearance in REPEAT for that reason; this page is the appearance row taken apart.
Four places a white candle can pick up yellow
The table sets out the usual sources and what each looks like in a side-by-side test. These are general candle-making observations, not CSI measurements, and any of them can coincide with a wax change.
| Source | Can a wax change move it? | What the puck test shows if this is it | What you would change |
|---|---|---|---|
| Base shade of the wax | Yes — directly | Unscented new-wax puck already creamier than unscented old-wax puck | Accept, re-shoot product photos, or choose another wax |
| Oil colour or oil–wax interaction | Yes — the same oil can behave differently in a new wax | Unscented pucks match; scented new-wax puck yellower | Oil or load for this wax; see 4827 |
| Light and storage | Yes — waxes can respond differently to light | Dark-set pucks match; window-set new-wax pucks yellow faster | Packaging, storage, display; no UV inhibitor is listed by CSI |
| Process: heat and time in the melter | Indirectly — a new routine or longer heating | Pucks match; production candles yellower | Heating time and temperature per the new maker's instructions |
| Oil lot | No — but it can coincide | Old and new both yellower than last year's retained candle | Split one lot across both waxes; compare with retained sample |
The puck test, step by step
Pucks are poured into a silicone mould — here CSI's 40-cavity square mould — so every sample has the same thickness and surface. CSI does not publish cavity weights for its moulds: fill one cavity with water, weigh it, and use that. This page uses an illustrative 10 g cavity; scented pucks at 8% are then 0.8 g of oil and 9.2 g of wax. Counts, light conditions and checkpoints are labelled working practice.
| Sample | Old wax (CSI 464) | New wax (CSI 468) | Stored |
|---|---|---|---|
| Unscented puck | 3 + 3 | 3 + 3 | One set in a dark box, one set in window light |
| Scented puck, Neroli 8% (0.8 g oil) | 3 + 3 | 3 + 3 | Dark box / window light |
| Finished 200 g candle, Neroli 8% | 3 | 3 | Normal storage; one of each burned later |
| Optional: unscented pucks of other candidate waxes | — | Chunks 3 · Soy Pearl 3 | Dark box — only if a whiter base is the goal |
| Sample | Old · dark | New · dark | Old · light | New · light |
|---|---|---|---|---|
| Unscented puck | ___ | ___ | ___ | ___ |
| Scented puck (Neroli 8%) | ___ | ___ | ___ | ___ |
| Finished candle top | ___ | ___ | — | — |
| Retained standard | reference | reference | reference | reference |
Does it need colour reformulation? It depends what you sell
Once you know where the yellow enters, the decision depends on the product. A candle sold as "white" is a colour claim; a candle sold as natural soy with a creamy look may not need any change at all. Dyed candles are a different case again, because a warmer base shifts every hue on top of it.
| Your product | Yellow comes from… | Practical options | What not to do |
|---|---|---|---|
| Sold as pure white | Base wax | Test other candidate waxes' unscented pucks; keep the old wax for white SKUs; or update the colour name and photos | Do not try to dye a cream wax white with coloured dyes — CSI lists no white dye |
| Sold as pure white | Oil in the new wax | Try the oil at a lower load (as its own test) or keep this oil in the old wax | Do not change load and wax in one round |
| Sold as pure white | Light | Opaque or boxed packaging; display away from sun | Do not rely on an additive — CSI lists no UV inhibitor |
| Natural / cream look | Any | Update photos and description; no reformulation needed | — |
| Dyed colour | Base wax | Re-run a small dye ladder in the new wax using the dye's product-page guidance | Do not assume the old dye dose gives the old shade |
Two tools in CSI's catalogue are relevant and need honest caveats. White mica (10 g ₹57.82) is sometimes used by makers for a surface shimmer; general practice commonly cautions that mica melted into the burning pool can clog a wick, so it belongs on a surface or in non-burning decoration, and only after a burn test. It is not a whitening agent for the wax itself. CSI's liquid dyes and dye chips add colour; they cannot take colour out. Changing dye brands and adding mica to a decorative candle cover those two changes as their own retests.
The priced colour-test kit
Grams use the CSI convention (oil = candle weight × load) plus a 5% pour-loss allowance, labelled as a working assumption. Each wax needs 700.6 g for three candles and 12 pucks; the Neroli for everything is 110.9 g.
| Item | Need | Buy | Price |
|---|---|---|---|
| Premium Coconut Soy Wax CSI 468 | 700.6 g | 1 × 1 kg | ₹650.00 |
| Neroli Fragrance Oil | 110.9 g | 1 × 100 g + 1 × 15 g | ₹783.52 |
| 40 Cavity Square Mould | 24 cavities used | 1 | ₹472.00 |
| Eco Candle Wicks Thin C1 | 6 | 1 × 10 | ₹59.00 |
| White Matte Glass Jar | 6 | 2 packs of 5 | ₹708.00 |
| Kit, old wax from stock | ₹2,672.52 | ||
| Luxury Soy Wax CSI 464 (only if you hold none) | 700.6 g | 1 × 1 kg | ₹507.40 |
| Kit, old wax bought | ₹3,179.92 | ||
| Optional candidate pucks: Chunks 500 g · Soy Pearl 1 kg | ~30 g each | smallest bags | ₹299.00 · ₹450.00 |
The mould is the one piece of kit that outlives the test: it is reusable, and every future wax lot can be checked with three unscented pucks against your retained standard. The optional candidate row is only for makers whose white SKUs cannot tolerate a creamier base — it buys the smallest bags of the other two CSI container waxes so their unscented pucks can sit in the same photograph. Neroli is ₹6.66 a gram at 100 g; 110.9 g is cheapest as 100 g + 15 g (₹783.52).

Keeping two waxes: what it costs
One common outcome is that the new wax is fine for most of the range and wrong for the white SKUs. Keeping the old wax for those is legitimate — it is what approved-material lists are for. At the 5 kg rates, the wax in a 200 g candle costs ₹93.36 in CSI 464 and ₹117.21 in CSI 468, so in this example keeping the white SKUs on CSI 464 is actually ₹23.85 a candle cheaper in wax. The real cost of two waxes is not price; it is two sets of stock, two lot records and one more chance of pouring the wrong wax into the wrong SKU.
| Line | One wax | Two waxes |
|---|---|---|
| Wax per 200 g candle (5 kg rate) | CSI 468: ₹117.21 | CSI 468: ₹117.21 · CSI 464 for white SKUs: ₹93.36 |
| Stock to hold | One wax | Two waxes — two reorder points |
| Retained samples | One per lot | One per lot, per wax |
| Recipe cards | Wax line identical | Wax line must name the wax per SKU |
| Risk | — | Wrong wax in the wrong SKU — label the pots |
Recording the colour result
File the photographs, the puck scores and the decision against each SKU. If the decision was "accept the creamier shade", update the product photos and any colour words in the listing at the same time — a customer comparing an old photo with a new candle is the most common source of "this isn't what I ordered".

If the colour change arrived with a new fragrance rather than a new wax, the darker-vanilla post covers colour stability for an oil change. If the surface rather than the shade changed, the rough-tops post is next. For dyed ranges, changing dye brands and raising dye concentration both reopen the burn test. If your range has many fragrances in the new wax, the ten-fragrance post shows how to group them so the scented pucks cover the range, and the window-light set pairs naturally with the summer storage test. And for the whole wax-change list, the checklist or back to the hub.
