A three ingredient balm: beeswax, shea and one oil, in the right proportions

Two three-ingredient balms in weight percent, lips at 15 percent wax and body at 8, with pour bands, kitchen scale limits and the first upgrade to make.

Three materials will make a balm that works. They will not make a balm that does everything, and the interesting part of a minimal formula is not what it contains but what its absence costs you. This page gives two tested three-ingredient formulas, one for lips and one for the body, the arithmetic for weighing them on a kitchen scale, and an honest account of the faults you have signed up for.

• Lips: 15 / 25 / 60
• Body: 8 / 27 / 65
• Melt hold: 78 to 80 C
• Smallest sensible batch: 50 g
• Shelf life: 9 to 12 months

What three ingredients can and cannot buy

A balm has three jobs, and each one maps onto a material class. It has to hold its shape in the container and on the skin, which is the wax. It has to have body, so that the film has substance and does not vanish in ten minutes, which is the butter. And it has to spread under light pressure, which is the liquid oil. One wax, one butter, one oil covers all three, which is why the three-ingredient balm is a real formula and not a compromise.

What you cannot cover with three is anything in the second tier: gloss, oxidative stability, wear time on a windy day, and heat resistance above about 32 C. Every one of those is normally bought with a small percentage of a specialist material, and every one of them is genuinely absent here. Nothing in this formula fails. Several things in it are simply mediocre, and it is worth knowing which before you make forty tubes.

The lip formula

Weight percent of the total batch, adding to exactly 100. The gram columns are for a 50 g batch, which is about the smallest a domestic scale handles honestly, and a 100 g batch, which fills roughly twenty 4.5 g tubes after allowing for what stays in the jug.

Fifteen percent beeswax is the middle of the 10 to 20 percent window for a twist-up tube. It is not an arbitrary choice made lower because there are fewer ingredients: with no cocoa butter and no hard wax in the formula, the beeswax is carrying the entire structural load, and 15 is where the stick stops smearing without becoming a crayon. In a hot climate, or if the balm will live in a trouser pocket, take it to 17 or 18 and drop the sunflower by the same amount. The full firmness ladder, and the conversion from the part-based ratios people usually start with, is at lip balm ratios.

The 60 percent liquid oil is high for a tube balm, and it is deliberate. With no castor oil to provide slip and no jojoba to thin the film, the sunflower has to do all of the spreading on its own, and a lower figure gives a stick that drags. Use high-oleic sunflower, not the bottle from the supermarket shelf; the difference is explained below and in high oleic oils.

The body formula

A tin balm is picked up on a fingertip, so it must dent under light pressure rather than support itself. Wax comes down, butter goes up slightly to keep the product from reading as an oil slick, and the oil takes the balance.

A 60 ml tin takes about 55 g of set balm, because balm has a working density near 0.92 g/ml rather than 1. The two-tin batch therefore leaves about 10 g in the jug and on the spatula, which is roughly the real loss at this scale. If your tins are a different size, multiply millilitres by 0.92 rather than guessing, and if you want to resize the whole formula for a different container count, the formula converter does the arithmetic without rounding errors creeping into the wax figure.

Eight percent wax is the low end of what still binds 65 percent liquid oil. Below about 6 percent the balm will weep oil onto the surface within a few weeks, particularly after a warm spell, because there is not enough crystalline network to hold the liquid phase.

Two degrees of freedom, and why every change costs something

This is the real difficulty of a minimal formula, and it is not obvious until you try to fix something. Three components summing to 100 give you exactly two independent variables. Change one and at least one other must move. There are no small levers left, only large ones, and each of them is coupled to a fault you would rather not have.

Hardness is the clearest case. In a fuller formula, wax sets hardness and butter sets cushion, and the two can be adjusted separately. Here they overlap: shea butter is roughly 30 to 45 percent solid at 20 C, so it is a structural ingredient as well as an emollient one. Raise shea to add cushion and you also add hardness. Raise it far enough to matter and you increase the crystalline stearin load, which is the graininess risk. So cushion, hardness and grain are all controlled by the same number, and you cannot separate them.

The same coupling applies to payoff. If the balm feels reluctant, the only correction available is more sunflower oil, taken from the wax or the shea, and both of those reduce the substance of the film. In a four-ingredient formula you would add castor and be done. Here you either accept the trade or you stop having three ingredients. That is the honest choice this page exists to make explicit.

Weighing this on a kitchen scale

Most kitchen scales read to 1 g, which is useless here: at a 50 g batch, 1 g is two percentage points of wax. A 0.1 g jewellery or coffee scale is the practical minimum, and it costs little. The trap is that resolution and accuracy are not the same number. A scale that displays 0.1 g typically holds its reading to about ±0.1 g at best, and cheap units drift with temperature and show linearity error across the range. Treat the displayed decimal as an indication, not a guarantee, and check the scale against a known mass before a batch that matters; the method is at weighing and calibration.

Read the top row carefully. A 10 g test batch can land anywhere between 14 and 16 percent wax, which spans the difference between a balm you like and one you think is too firm. People conclude that a formula is unreliable when what is unreliable is the scale, and they then change the formula to chase a fault that never existed.

The working rules follow from the table. Nothing gets weighed below 0.5 g, because at 0.1 g resolution a 0.5 g weighing is only good to twenty percent. With a three-ingredient formula whose smallest component is 8 percent, that floor is cleared by any batch above about 7 g, so resolution is never the binding constraint here: accuracy is. Make 50 g minimum, and 100 g or more if you are filling tubes. Weigh each material into its own dish rather than taring and adding into one jug, so that an error on the wax does not silently become an error on the oil as well. And weigh the oil last, since it is the largest number and the least sensitive to being a tenth out.

Method

1. Weigh all three into a heatproof jug. Beeswax first, then shea, then the oil. Nothing needs to be added at a different stage, because there is nothing heat sensitive in the formula.
2. Hold at 78 to 80 C. Stand the jug in simmering water until the liquid is completely clear. Look at it against a light: any haze is undissolved shea stearin, and it will come back as grain. Give it five minutes past the point it looks melted.
3. Pour at the right band. Tubes at 66 to 72 C (151 to 162 F), tins at 62 to 68 C (144 to 154 F). Fill each container in one continuous movement, stopping about 1 mm below the rim. The reasoning behind these windows is at pour temperatures.
4. Cool fast. Move the filled tubes or tins to a cool surface, or into a fridge for fifteen to twenty minutes. Fast cooling is the single strongest defence against grainy shea. Do not use the freezer, which cracks the surface.
5. Top up once. After 10 to 15 minutes the centre will have dished. Rewarm the residue in the jug and pour a thin second layer for a level top. Tube technique is covered at filling lip balm tubes.
6. Cure 24 hours before judging. Wax crystallisation continues for a day or two after the balm is visibly solid, and a stick judged at two hours reads softer than the same stick tomorrow.

What each missing ingredient costs you

These are the materials a fuller formula would contain, what their absence removes, and how the absence shows up in use.

The castor omission is the one people notice first. Castor oil is 85 to 90 percent ricinoleic acid, which makes it unusually viscous and tacky for a liquid oil, and it is the reason commercial balms look glossy and stay put. Sunflower oil cannot substitute for it at any percentage, because the property that matters is viscosity rather than polarity. If your balm reads dull, the cause is structural, not a mistake, and the mechanism is set out at matte instead of glossy balm.

Choosing the three materials well

With so few components, grade matters more than it would elsewhere. Buy filtered cosmetic-grade beeswax rather than candle grade, which carries propolis and debris that show as dark specks. For shea butter, refined and unrefined grain by the same mechanism, so choose on smell: unrefined shea has a distinct nutty, slightly smoky odour that survives into a lip product and that a fair number of people do not want on their mouth.

The oil choice is the one that decides shelf life. High-oleic sunflower is bred to run above 80 percent oleic acid with linoleic under about 10 percent, while commodity sunflower oil from a supermarket typically runs 48 to 74 percent linoleic. Linoleic acid has two bis-allylic hydrogens per molecule and oxidises perhaps an order of magnitude faster than oleic, which is why the same formula gives nine to twelve months with one oil and closer to six with the other. Buy the oil labelled high oleic, and read kitchen oils in balms before substituting anything from the kitchen cupboard. Without an antioxidant in the formula there is nothing to slow the process down, so the raw material choice is the whole defence.

Failure modes

The fourth and fifth ingredients

If you add one thing, add castor oil at 10 percent taken from the sunflower. It is the largest single improvement available, it changes the finish from matte to glossy, and it roughly doubles how long the balm stays where you put it. If you add a second, add mixed tocopherols at 0.1 percent, which is the cheapest shelf life you will ever buy; the working range and the reason more is not better are at vitamin E and antioxidants.

Note what the second addition does to the batch arithmetic. At 0.1 percent, a 100 g batch needs 0.1 g of tocopherol, which a 0.1 g scale cannot weigh to better than plus or minus one hundred percent. This is the point at which the formula stops being a beginner formula: you now need either a 0.001 g scale, or a 500 g batch, or the habit of blending a premix and taking a portion of it. Adding a sixth and seventh ingredient (cocoa butter for snap, a hard wax for heat) is easy by comparison, because they are used at whole-number percentages. The six-ingredient version of the same balm, with the reasoning for each figure, is at how to make lip balm.

When three is the right answer

Three ingredients is the right choice in four situations: when you are learning, and want to understand what each material does before compounding variables; when someone has a reactive skin history and every additional material is another suspect; when you are making a small quantity for yourself and a shorter shelf life is irrelevant because it will be gone in three months; and when cost per gram is the binding constraint, which is covered at low cost balm formula.

It is the wrong choice if you are selling. Not because it is unsafe, but because the two faults it guarantees, a matte finish and a shelf life around nine months, are exactly the two things a buyer notices and complains about. A minimal ingredient list is a marketing position, and it is one that costs you performance rather than earning it. Decide which of those you are optimising for before you make the batch, not after.
