I Want to Make Diwali Candles Several Months Before the Festival — What Raw-Material Characteristics Should I Prioritise for Storage Through Indian Weather?

Why early production changes the material choice

Making festive stock months before Diwali is sensible. It spreads the work, smooths cash flow and keeps you out of the last-minute rush for materials. But a candle poured weeks or months before it is sold has to cross a stretch of Indian weather that a freshly poured candle never meets: hot afternoons, monsoon humidity, temperature swings between day and night, and boxes stacked in rooms that were never designed for storage.

That changes what you look for in each raw material. For a candle sold within days, you mostly care about how it burns. For a candle that waits months, you also care about how it ages: whether the colour holds, whether the top stays smooth, whether the scent is still the one you approved, and whether the container protects it. This page ranks those characteristics and costs a plan for 400 candles.

The characteristics to prioritise, material by material

Fragrance: colour stability comes first

Vanillin is the usual reason a light candle drifts in colour, and the change keeps developing in storage. CSI's pages are open about it. Chocolate Fudge states that the wax will warm in tone over time. Dark Vanilla states it will yellow white or light-coloured wax. Roasted Coffee warns of slight yellowing in white wax. All describe this as cosmetic, but a customer opening a candle that is visibly darker than the photo may not agree.

For light wax in stored stock, start with oils that state 0% vanillin or low discolouration risk. Sandalwood states 0% vanillin, a 203°C flashpoint and up to 10% in soy. Juicy Orange's page states low discolouration risk because its base is light musk and amber rather than vanilla, with a soy range of 8 to 10%. Both suit a festive range. If you want a gourmand scent for Diwali, put it in a darker or coloured wax design where warming does not show.

Wax: the shelf life is for the bag, not the candle

CSI 464 states a 60-month shelf life in cool, dry storage. That is reassuring for raw wax you buy early, but it says nothing about a poured, scented candle in a hot room. Soy candles can show frosting or surface changes over time, and repeated warming and cooling can disturb tops and glass contact. No CSI wax publishes a temperature it survives, so the only proof is your own stored samples.

Dye and container

Festive colours are tempting, but a dye that looks perfect on the day of pouring may shift in light. CSI publishes no dosage or light-stability data for its dyes, so test a dyed sample kept in daylight beside one kept in a closed box. A coloured or opaque jar hides small shifts from view; the 120 g shiny jar comes in amber with a black lid, and in black or pink with a golden lid. A lid also keeps dust off the surface during months on a shelf. Dye also affects the burn, so wick-test the final coloured candle, not just the plain one.

A costed 400-candle early-production plan

The product is a 120 g candle in the amber shiny jar with a black lid, at a suggested 8%: 110.4 g of CSI 464 and 9.6 g of oil. Two scents, 200 candles each: Juicy Orange and Sandalwood.

Pilot. Pour eight candles: three of each oil plus two unscented controls. They use 8 × 110.4 g = 883.2 g of wax from a 1 kg pack at ₹507.40, and 3 × 9.6 g = 28.8 g of each oil. Juicy Orange 50 g costs ₹379.00. Sandalwood's 50 g and 100 g packs were out of stock on the pull, so two 15 g bottles at 2 × ₹93.22 = ₹186.44 give 30 g. Two packs of five jars at 2 × ₹236.00 = ₹472.00 and a 20-pack of Eco C1 at ₹118.00 complete it, for ₹1,662.84.

Production. 400 candles need 400 × 110.4 g = 44,160 g of wax. Four 10 kg packs and one 5 kg pack, at 4 × ₹5,074.00 + ₹2,537.00 = ₹22,833.00, give 45 kg and leave 840 g, enough for seven retained samples. Each oil needs 200 × 9.6 g = 1,920 g. Juicy Orange as four 500 g bottles costs 4 × ₹3,749.00 = ₹14,996.00, two rupees less than two 1 kg bottles. Sandalwood as two 1 kg bottles costs 2 × ₹5,026.80 = ₹10,053.60. Jars for 407 candles, less the two left from the pilot, means 405 more: 81 packs at 81 × ₹236.00 = ₹19,116.00. Wicks: 407 less the 12 left from the pilot is 395, so four 100-packs of C1 at 4 × ₹590.00 = ₹2,360.00. The oil left after production, about 101 g of Juicy Orange and 81 g of Sandalwood, covers the seven retained samples.

Why the pilot comes first even when time feels plentiful

With months in hand it is tempting to pour everything at once and relax. Resist it. The pilot candles are the only ones that can age ahead of the main stock, so every week they sit before production begins is a week of storage evidence you gain for free. If a pilot candle darkens or frosts in its first few weeks, you have changed one oil or one wax for the price of eight candles, not four hundred.

Packaging, labels, labour, shipping and GST are excluded. Juicy Orange is the dearer oil per gram here, so if margin is tight, the festive range could lean on Sandalwood for volume.

Storing the stock and checking it before dispatch

Buy this to test: the ₹1,662.84 pilot above, poured as early as you can so the samples have time to age before you commit. Buy this once the pilot holds: the production wax, oil, jars and wicks listed above, ₹69,358.60 in all, before your own packaging.
