Solid perfume recipe and wax ratio

A solid perfume sized to your tin, with the wax share that decides whether it is a balm or a brick — and the harder waxes corrected for.

INPUTS
g
%
15% a soft balm · 25% the standard · 40% firm enough for a twist-up tube. The base is the wax and carrier oil together, before the fragrance goes in.
The default. Sets firm, has a faint honey smell of its own that shows through a delicate blend, and is forgiving about the ratio.
%
3–12% of the finished weight — several times a spray perfume's load, because there is no alcohol throwing it into the air. Your own supplier's IFRA category 5A figure is the number that binds.
Add the fragrance off the heat, once the jug has stopped steaming. Stirred into hot wax, the lightest materials evaporate straight out of it — which is exactly the part of a blend a solid perfume struggles to hold anyway. There is no alcohol in this and nothing to macerate: it is finished when it has set.

Wax is quoted against the BASE rather than against the tin, so changing the fragrance load does not quietly change how firm the balm sets. Swapping to a harder wax at the same share sets much firmer — candelilla and carnauba melt well above beeswax's 63 °C. Test a teaspoon on a cold saucer before you pour the batch.

How this is worked out

A solid perfume is a wax matrix holding fragrance against skin, and it shares nothing with the alcohol dilution model — no strength band, no note pyramid worth quoting, nothing to macerate. The arithmetic runs from the tin inwards: fragrance is a share of the finished weight, and what is left is the BASE, which is then split between wax and carrier oil. Wax is quoted against that base rather than against the tin, so changing the fragrance load cannot quietly change how firm the balm sets — the two decisions stay independent. The wax share is effectively the whole of the texture: 15% is a soft balm at 2.1 g in a 15 g tin, 25% is the standard at 3.5 g, and 40% is firm enough for a twist-up tube at 5.6 g. Past that it stops releasing to a fingertip, which reads as a perfume with no smell rather than as a balm that is too hard — and sends people off adding more fragrance to fix the wrong problem.

base = tin weight × (1 − fragrance%)
wax = base × wax share of base
carrier = base − wax
fragrance = tin weight × fragrance%

Questions makers ask

What is the wax to oil ratio for solid perfume?
About 25% wax to 75% carrier oil, measured as a share of the base before the fragrance goes in — roughly one part wax to three parts oil. In a 15 g tin that is 3.5 g of wax and 10.6 g of oil. Below 15% it will not hold its shape in a warm bag; above 40% a fingertip stops picking anything up.
Why is wax quoted against the base and not against the tin?
So that changing the fragrance load does not quietly change how firm the balm sets. If wax were a share of the whole tin, raising the fragrance from 6% to 10% would soften the balm as a side effect — which is not what anyone means to do. Quoting it against the wax and oil together keeps the two decisions independent.
Can I swap beeswax for candelilla or carnauba?
Yes, and not at the same weight. Beeswax melts at 63 °C, candelilla wax at 70 °C and carnauba wax at 82 °C — so a beeswax recipe made with the same weight of either harder wax sets like a candle. Drop the wax by about a third and test a spoonful on a cold saucer before committing the batch.
How much fragrance goes in solid perfume?
Around 6% of the finished weight — 0.9 g in a 15 g tin — with about 12% as the ceiling. That is several times a spray perfume's load, because there is no alcohol throwing it into the air and it has to be smelled off the surface. Past the ceiling it stops absorbing into the wax and weeps out as an oily film.
Which carrier oil should I use?
Jojoba is the nicest to wear and barely goes rancid, because it is a liquid wax rather than an oil. Fractionated coconut oil is cheaper and effectively odourless. Avoid anything with a strong smell of its own — olive and unrefined coconut both compete with the blend and both go off faster than a tin gets used.
Does solid perfume need to macerate?
No. There is no alcohol, so there is nothing for the materials to settle out of — it is finished when it has set, usually within the hour. If you want the blend itself to be right, macerate the fragrance oils together first and make the solid from the finished compound.
Why is my solid perfume grainy?
It cooled unevenly or it was moved while setting. Beeswax in particular crystallises coarsely if it cools slowly in a draught. Remelt it gently, pour a little warmer, and leave the tins somewhere level and undisturbed for an hour.
