Fragrance Oils for Soy Candles at 6–8% Fragrance Load

The formula, and the percent-of-wax mistake

The convention used across this cluster, and by the wax makers' ceilings, is: oil = total candle weight × load, and wax = total − oil. A 200 g candle at 8% is 16 g of oil and 184 g of wax. The other common method weighs the wax first, then adds oil as a percentage of the wax: 200 g of wax plus 8% is 16 g of oil and 216 g of candle. That candle is 7.41% oil, not 8%. It is also 16 g heavier than planned, which matters if your jar is filled to a line.

At 6–8% the gap is small, about half a point. It matters in three places. First, when you compare your load with a wax's ceiling: 10% of the wax weight is only 9.09% of the candle, so a maker who believes they are at CSI 464's 10% limit is below it. Second, when you cost a candle: your grams of oil are what you pay for, so cost from grams, not from the percentage. Third, when you scale. A batch planned as a percentage of the wax needs more wax per candle than you expect. Pick one convention and write it on your batch card. We recommend percent of total, because that is what the wax ceilings mean.

Grams at 6%, 7% and 8%

The table gives oil and wax for five candle sizes. The 50 g and 85 g rows use vessels with a published capacity: the Heart Cutout Velvet Jar (50 g wax capacity) and the Golden Aluminium Tin (85 g fill). The 150 g and 300 g rows are illustrative. Most jars do not have a published fill weight, so weigh one filled jar of your own before planning.

At the small end, precision matters. In an 85 g tin, the difference between 6% and 8% is 1.70 g of oil. A kitchen scale that reads in whole grams cannot tell 7% from 8% at that size. Use a scale that reads to 0.1 g, such as the Candle Making Weighing Scale (₹354.00, verified 10 September 2026). At the large end, a 300 g candle at 8% takes 24 g of oil. That is 1.5 times the 200 g figure, so cost it separately.

What each load costs

Load is a performance decision first and a cost decision second. It is still a cost decision. The table prices the oil in a 200 g soy candle at 6%, 7% and 8% for four oils and the median in-stock 100 g, all at the 100 g rate. The last column is the cost of one extra point of load.

For a value oil like Orchard Pear, moving from 6% to 8% adds ₹15.20 a candle. For Santal Noir it adds ₹36.76. Across a 100-candle month those are ₹1,520.00 and ₹3,676.00. Put the other way: if 6% or 7% gives the same result as 8% in your burn test, you save that money every month for as long as the scent sells. That is why a side-by-side at 6, 7 and 8% belongs in every soy maker's routine. Strong fragrance oils for soy has a load-ladder protocol you can use.

Headroom to each wax's ceiling

Headroom is the gap between your working load and the wax's stated maximum. It tells you how much room you have to test if an oil is quiet. The ceilings are the wax makers' formulation limits, not regulatory limits. Going above them is linked, in general practice, to oil the wax cannot hold well.

The practical reading: if you already know your oils sometimes need more than 10%, pour in Luxury Soy Wax Chunks (₹599.00 a kilo). If you work at 6–8% and rarely test above 9%, CSI 464 (₹507.40 a kilo) gives you enough headroom at a lower wax cost. The saving is ₹16.85 per 200 g candle at 8%. For Natural Soy Pearl (₹450.00 a kilo), check the product page or ask us on WhatsApp for the wax maker's figure, and treat 6–10% only as a labelled test range until you have it.

When to go above 8%

Makers usually raise the load because a candle seems weak. Before you do, rule out the cheaper causes. The steps below are ordered from least to most expensive per candle.

Two signals mean you should go down, not up. One is oil beading or wet patches on the set wax (sweating), which in general practice suggests more oil than the wax is holding well. The other is soot or a heavy flicker in the burn. Both are reasons to test a lower load before selling.

A 48-tin batch at 7%

Here is a worked batch in the middle of the band: 48 Golden Aluminium Tins (85 g fill), 16 in each of three scents, at 7% in CSI 464. Each tin takes 5.95 g of oil and 79.05 g of wax. Each scent needs 95.2 g of oil, or 99.96 g with a 5% allowance, so one 100 g bottle per scent is just enough. The wax is 3,794.4 g, or 3,984.1 g with the allowance, so four 1 kg bags.

Material cost covers oil, wax, wick and tin. It excludes labour, packaging, freight and GST. Small formats make the load decision cheap in absolute terms, a few rupees a tin, but the same percentages apply. A tin range is also a good place to find your load before committing it to 200 g jars. Pour a few tins at 6%, 7% and 8% from each 100 g bottle before the main batch.

Shopping list: 48 tins at 7%

Everything for the worked batch. Oil and wax prices are CSI live pricing, pulled 24 September 2026. The tin price comes from the 24–25 September pull, and the wick price was verified on 10 September 2026. Delivery and GST are not included.

Carry-over: 4.8 g of each oil before pour loss, about 16 g of CSI 464 after the allowance, and two wicks. If you would rather run the batch at 8%, each scent needs 108.8 g of oil (114.24 g with allowance), so add a 15 g tester or a 50 g bottle per scent. That is the load decision showing up on your shopping list.
