I Need to Manufacture 500 × 200 g Soy Candles at 8% Fragrance Load — How Many Kilograms of Wax and Fragrance Oil Should I Order?

The kilograms, in one line each

At CSI's convention the 8% is a share of the finished candle. Each 200 g candle is therefore 16 g of fragrance oil and 184 g of wax, and 500 of them need 92 kg of wax and 8 kg of oil before any allowance. That is the whole calculation. Every other number on this page is what happens when you add the test candles, rejects and pour loss you will really have, and then round to bags you can really buy.

The mistake that costs money at this scale is reading "500 × 200 g" as "100 kg of wax" and buying the 8 kg of oil on top. That orders 8 kg more wax than the candles can hold — 8.7% too much. Carry the same mistake through the allowances and it asks for 107.20 kg of wax instead of 98.63 kg: 8.58 kg too much, about ₹3,798.00 of Soy Pearl that sits on the shelf after the order ships. At 100 candles that error is a couple of bags; at 500 it is a pallet corner.

Two shortcuts make the table easy to carry in your head. Every 100 candles of 200 g at 8% is 18.4 kg of wax and 1.6 kg of oil. And the shortcut's over-order is always exactly the oil weight, because it counts the oil twice — once inside "100 kg of wax" and once in the bottles on top. The actual wax weight per candle post explains the split for a single candle; the 1,000 × 200 g post doubles everything here and compares all four CSI container waxes at that scale.

From 100 kg of candle to a purchase quantity

The allowances go on in a fixed order, each once. Ten whole test candles first — enough for a three-candle trial of two wick candidates plus four spares to check cold and hot throw before the run. Then a 2% reject allowance (an example; use your own history), applied by dividing by 0.98 so that 2% of what you pour can fail and you still have 500. Then 3% pour loss on the wax and oil, which is what sticks to jugs, melters and the pouring funnel. Then 2% breakage on the glass only. All four figures are labelled working assumptions — replace them with your own.

So the purchase quantities are 98.63 kg of wax, 8.58 kg of oil, 521 wicks and stickers, and 531 jars. Notice the oil is still exactly 8% of the mixture at every step: the allowances scale the batch, they never change the formula. The 105-or-110 pieces post argues the size of the buffer itself; the 1,000 saleable candles post splits it into pilots, burn tests, rejects and replacements.

How many bags: the same 98.63 kg in each CSI wax

CSI's listed container soy wax bags stop at 10 kg. Natural Soy Pearl is the one exception, listed at 50 kg as well, in limited stock — confirm on WhatsApp before you plan around it. The table shows the cheapest listed in-stock cover for the same requirement in each wax, chosen to keep the bag count sensible where the price is a tie.

Three pack facts decide those rows. Soy Pearl's 50 kg bag is not cheaper per kilo: ₹21,240.00 for 50 kg is ₹424.80 a kilo, exactly the 5 kg and 10 kg rate — so 9 × 10 kg + 1 × 5 kg + 4 × 1 kg costs the same ₹42,156.00. Take the 50 kg bag if it suits your storage, not for the price. Chunks are cheapest in 5 kg bags: ₹2,995.00 per 5 kg is ₹599.00 a kilo, while the 10 kg bag is ₹599.90; the 500 g bag is a rupee a kilo cheaper still, but nineteen 5 kg bags are a more sensible delivery than almost two hundred 500 g bags. CSI 464 and CSI 468 are flat from 5 kg, so their 10 kg bags simply mean fewer bags.

The spread between Soy Pearl and Chunks on this order is ₹17,145.00. That is real money, and it is the honest case for testing the cheaper wax first. It is not a performance verdict: CSI publishes no throw, frosting, adhesion or heat data for any wax, and Soy Pearl's page publishes no fragrance ceiling, so an 8% Soy Pearl candle is a tested starting point rather than a figure inside a stated limit. Chunks' page states a 13% maximum, which covers 8% with headroom. If you already pour one of these and your candles pass, keep it — the one-large-wax-pack post covers why switching wax mid-order is the expensive kind of saving.

The oil in kilograms, and in bottles

The oil is 8.58 kg with allowances. CSI's oils stop at 1 kg per listing, so a multi-kilo order is several 1 kg bottles (or a WhatsApp quote for larger volumes; no discount figure is published). Japanese Cherry Blossom is one of the oils that gets slightly cheaper per gram at 1 kg — ₹4.84 a gram against ₹5.00 at 100 g and 500 g — so the cheapest cover is 8 × 1 kg + 1 × 500 g + 1 × 100 g for ₹41,736.00, leaving 24 g (₹114.89). Buying the same oil in 100 g bottles would cost ₹43,000.00, ₹1,264.00 more, and mean 86 bottles to open.

That break is the exception, not the rule. Of the oils that list both 100 g and 1 kg, most are within about 1% per gram; only a couple of dozen are 5% or more cheaper at 1 kg. On CSI's listed catalogue a bigger bottle mostly buys fewer bottles and stock security. If you are running the same 500 candles at 6% or 10%, the oil moves by 2.00 kg per two points before allowances — the 6% versus 8% post and the 1,000 × 200 g at 10% post work those through.

The priced order, and what waits for the wick test

This is a single-fragrance order for your own range, so the oil does not wait for a client. The only material that depends on a result is the wick: wick size per jar diameter is not published for any CSI wick, and no chart can replace a burn in your jar. So the wax, the oil, the jars and the stickers are stage one, along with two small wick packs for the trial — Eco Thin C1 (20-pack; the 10-pack is out of stock) and Eco Thick C2 (10-pack). The production wicks are stage two.

Without allowances, one candle's material at production rates is ₹232.34 in Soy Pearl and ₹264.39 in Chunks (184 g of wax, 16 g of oil at the 1 kg rate, a ₹5.90 Thin C1 wick and a ₹70.80 jar). The order works out at ₹252.90 per saleable candle because it also pays for the trial, the rejects, the pour loss, the breakage and the pack rounding. The jar is the largest single line — ₹37,878.00, more than the wax — which is worth knowing before you choose glass for a price-sensitive range.

Receiving 100 kg of wax: what to check before you pour

A 500-candle order is often the first time a workshop takes in this much material at once, and a few minutes at the door save a bad week later. CSI publishes no lot numbers, certificates of analysis or batch-consistency data, so the record-keeping is yours. It does not need to be elaborate.
