I Want to Make a Tuberose Candle With Strong Diffusion but My Previous Floral Fragrance Disappeared in Wax — What Should I Look for When Buying the Fragrance Oil?

Why your last floral disappeared

White florals carry a lot of their character in lighter, more volatile materials. That makes them beautiful on a smelling strip and fragile in a hot process. Before you spend money on another oil, check the four usual causes in order, because three of them have nothing to do with the bottle.

If you cannot answer the first three from your notes, repeat the old test properly before replacing anything. It costs one candle and may save you a new bottle.

What to read on the page before buying a floral oil

Bottle impressions tell you about the top of the fragrance, not the burn. The product page gives you harder facts, and they decide how you handle the oil.

Notice what the page does not claim: no burn data and no diffusion figure. Strong diffusion is something you test in your jar, not something you read. And because the listing names tuberose alongside gardenia, decide in your own room whether it reads as tuberose for your customer before you build a product name around that word.

The test matrix for diffusion

Diffusion depends on oil, load, wax and wick together, so the matrix changes one thing at a time. Load here is a share of total candle weight: a 200 g candle at 8% is 16 g of oil and 184 g of wax; at 10% it is 20 g of oil and 180 g of wax.

Why CSI 468 at all? It is a coconut-soy blend with a stated melt point of 50–53°C, a pour of 58–60°C and a stated load up to 13%. A lower-melting wax can form its pool differently from CSI 464, and that is worth one comparison for a floral that struggled before. Keep both waxes at 10% so the oil, not the load, is the only difference between candles 3–4 and 5–6.

The 200 ml clear salsa jar is the vessel here because the page lists a 63 mm lug cap and it is economical for test pours. CSI publishes no internal diameter for it, so measure yours and note it on the test sheet; the wick result belongs to that measured width.

Adding a low-flashpoint floral safely

The method is where most florals are lost. Melt the wax, then let it cool before the oil goes in. With Gardenia, the page states to add below 98°C. CSI 468's stated pour range of 58–60°C sits comfortably under that, and CSI 464 can be handled the same way: oil in once the wax is below 98°C, a thorough gentle stir, then pour.

After pouring, label every jar with wax, load and wick. Cure for at least the 48–72 h the soy pages state, then burn. Repeat the throw check around day 7 as a suggested starting point, since florals can open up after a longer rest.

For the diffusion test itself, use the same room for every candle, burn for a set period you choose, step outside, and return to judge it fresh. Score how far into the room the scent reaches, not just how it smells over the jar. A simple way, as a suggested starting point, is to mark three spots: beside the candle, the middle of the room and the far corner. Note at each spot whether the white floral is clearly there, faintly there or absent, and repeat at the same times for every candle. A floral that only shows beside the jar has throw but not diffusion, and diffusion is what your brief asked for. Never leave a candle burning unattended, and stop any test that smokes or flares.

What a Gardenia candle costs at each setting

Per-gram prices come from the 1 kg packs for oil and wax: Gardenia ₹4.332, CSI 464 ₹0.5074, CSI 468 ₹0.650. A clear salsa jar is ₹2,950.00 ÷ 100 = ₹29.50 at the 100-piece pack, and Eco C2 is ₹9.44.

Going from 8% to 10% in CSI 464 adds ₹15.30 per candle. Moving the 10% version into CSI 468 adds another ₹25.67. Those are the two premiums your room test has to justify. Leave room in your own pricing for packaging, labels, labour, shipping and GST, none of which appear here.

Buy this to test, buy this once validated

The matrix uses 16 + 16 + 20 + 20 + 20 + 20 = 112 g of Gardenia, so buy 100 g ₹433.00 plus 15 g ₹105.02. Add CSI 464 1 kg ₹507.40 (it needs 728 g), CSI 468 500 g ₹325.00 (it needs 360 g), two five-packs of clear salsa jars at 2 × ₹200.60 = ₹401.20, Eco C1 20 wicks ₹118.00 and Eco C2 10 wicks ₹94.40. The test set comes to ₹1,984.02.

Once one setting wins, buy for the run. Fifty candles at 10% need 50 × 20 g = 1,000 g of Gardenia, which is the 1 kg pack at ₹4,332.00, and 50 × 180 g = 9,000 g of the winning wax: a 10 kg pack, either CSI 464 at ₹5,074.00 or CSI 468 at ₹6,370.00. Fifty clear salsa jars are ₹1,475.00. Do not buy the 1 kg before candle 3, 4, 5 or 6 has clearly beaten your old floral in the same room.
