I'm Using 6% Fragrance Load but My Candle Smells Weak — Should I Immediately Increase It to 10% or Troubleshoot the Wick and Wax First?

The free checks

The first four checks use the candles you already have. They take a day or two of observation and no purchase. Skipping them is how makers end up with a 10% candle that still smells weak, because the problem was never the load.

The melt pool check is the one that most often points to the real cause. Hot throw comes from the surface of the pool. If a 200 g candle's pool covers two-thirds of the surface after three hours, a third of the wax is not releasing scent at all, and more oil will not change that. A wick that reaches a full pool will. If the pool is full and even, and the candle still reads weak in a fair test, the load becomes a reasonable suspect.

The cheapest paid fix: the wick

If the pool falls short, the wick is the first thing to change, and it is cheap. On CSI's Eco Candle Wicks, the step from Thin C1 (₹5.90) to Thick C2 (₹9.44) adds ₹3.54 to a candle. Moving from 6% to 8% Fresh Strawberries adds ₹14.16; to 10%, ₹28.32.

Two caveats. A bigger wick is not automatically right: too large and the candle can soot, tunnel the other way or overheat the jar. And no table can tell you the correct wick for a jar diameter — that is a burn test. What the table shows is order: if the wick fixes the pool, you have solved the problem for a few rupees, and the load can stay at 6%. If the flame looked fine and the pool was full, skip this step and move to the load.

Then step the load, one rung

A two-point step is a fair test of whether the oil is the limiting factor. If 8% fixes it, you have saved 4 g of oil on every candle compared with 10%. If 8% helps but not enough, 10% is the next rung — and you now know the direction. Jumping straight to 10% skips that information, and in some wax-oil-wick combinations the higher load performs worse, for reasons set out in I Tested My Fragrance at 6%, 8% and 10% in Soy Wax but the 8% Candle Smells Stronger than the 10% Candle — Why Can Adding More Fragrance Reduce Performance? and I Reduced My Fragrance Load from 10% to 8% and the Candle Suddenly Burns Better — How Can Less Fragrance Sometimes Produce Better Overall Performance?.

Natural Soy Pearl Wax has no published fragrance ceiling in our data. The 6–10% range here is a labelled test range for a wax without a published maximum, not a specification. Before testing above 10%, check the product page or ask CSI on WhatsApp for the wax maker's stated maximum. If you want a wax with a published ceiling and more headroom, Luxury Soy Wax Chunks are rated up to 13% — though, as My Soy Wax Supplier Says the Wax Can Hold 12% Fragrance Oil — Does That Mean I Should Actually Use 12% for the Strongest Hot Throw? explains, a ceiling is not a target.

What a jump to 10% costs

A single candle hides the cost. A month of production shows it. At 120 candles a month, here is what each rung adds with Fresh Strawberries at its 1 kg rate — one of the oils where the kilo is cheaper per gram than 100 g (₹3.54 against ₹3.78).

Going to 10% without cause adds ₹3,398.40 a month, and 960 g more oil to buy and store. If a wick change had fixed it, the same month's extra would have been ₹424.80. That is the whole argument for troubleshooting first, in one pair of numbers.

The staged test, priced

If the free checks do not find the cause, run this twelve-candle test. It tests the wick at 6% first, then the load on the better wick. Pour all twelve in one session so they cure together.

The allowance is a working assumption for pour loss and test burns (plan 3–5%). The spare wicks and jars are deliberate — a second round is common, and it is cheaper to have them than to reorder. Material cost per candle excludes labour, packaging, freight and GST.
