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?

What a stated maximum means

A wax maker's stated fragrance maximum is a formulation limit. It says that up to that load, the wax is expected to set, hold the oil and burn acceptably in the maker's own testing conditions. It is not a legal or regulatory figure, it is not a promise about any particular oil, and it says nothing about which load gives the best scent. Your supplier's 12% should be read the same way, and we take it as given: it is their figure for their wax.

Two points follow. First, a ceiling applies to the wax, but every oil behaves differently in it. A load that one oil sits comfortably at can make another sweat or flood the wick — My Candle Sweats Oil at 12% Fragrance Load but Not at 8% — Does That Mean I Have Exceeded the Practical Fragrance Capacity of My Wax? covers a candle that sweats at 12% but not at 8%. Second, nothing in CSI's data allows a load above 13%, and we will never recommend one.

First, which 12%?

Many supplier figures and forum recipes quote load as a percentage of the wax. CSI quotes it as a share of the finished candle (I'm Making a 1 Kg Soy Wax Batch at 8% Fragrance Load — Do I Add 80 g Fragrance Oil to 1 Kg Wax or Should the 8% be Calculated from the Total Finished Candle Weight? explains why). The two are not the same number.

If your supplier meant 12% of the wax, their ceiling is about 10.71% of the finished candle, and a recipe at 12% of the finished weight would be over it. That is exactly the kind of misunderstanding that produces sweating or a struggling wick and gets blamed on the oil. Clarify the base before you test anywhere near the ceiling.

What the extra four points cost

In a 200 g candle, 8% is 16 g of oil and 12% is 24 g — half as much oil again. The rupee gap depends on the oil. Here are three oils from three price tiers, each at its 1 kg rate, over a 300-candle run.

On a value oil the difference is modest. On a premium oil like Santal Noir it is ₹21,888.00 over 300 candles — money that only makes sense if 12% is measurably better in a blind test. Full material cost for a 200 g Santal Noir candle in Chunks, with an Eco Thin C1 wick and a White Matte Glass Jar, is ₹332.84 at 8%, ₹366.92 at 10% and ₹401.00 at 12%, excluding labour, packaging, freight and GST.

Finding your optimum below the fence

The test below runs three loads up to your supplier's ceiling, with three candles each, poured and cured together and burned blind. It works in any container soy; the list prices it in Luxury Soy Wax Chunks, whose stated 13% maximum sits above the top rung. If your wax is CSI 464, run 6 / 8 / 10% instead.

If 12% wins clearly with a clean flame and a dry surface, you have earned the right to use it — and now you know what it costs per candle. If 10% or 8% ties it, you have found money.

The priced test list

If your production wax stays with your current supplier, run the test in that wax instead and keep only the oil, wicks and jars from this list. The method does not change. The wick is an example; if the 12% candles struggle, the thicker Eco C2 at ₹9.44 is the next step to try, as covered in My Candle Smells Strong at 10% Fragrance Load but the Wick Struggles — How Do I Determine Whether Reducing Fragrance or Increasing Wick Size Is the Better Solution?.
