Shea butter vs cocoa butter for lip balm: which holds in a warm pocket, and which blooms?

Cocoa butter is still a quarter solid at 30 C, so it holds a summer tube better than shea, but a pocket is just where it blooms. The figures and the fix.

For a lip balm tube that has to hold in a warm pocket, cocoa butter is the better butter, because measured by pulsed NMR, it was still 25.6 percent solid at 30 C, while crude shea is close to half a soft fat, and the shea fraction made mostly of that fat melted at 25 C. But neither butter is what keeps a tube standing at pocket heat: cocoa butter was only 10.3 percent solid at 35 C, so the wax does that job. The catch is bloom, the white film on old chocolate, because a pocket sits inside the melting range of cocoa butter's normal crystal form, and melting and setting again is how bloom starts, and adding shea does not stop it.

• Cocoa butter solid: 70.5% at 20 C, 25.6% at 30 C, 10.3% at 35 C
• Crude shea: 46.8% StOSt, 42.1% StOO
• Shea olein melts at 25 C
• Cocoa butter form V melts at 30.0-34.5 C
• Front of thigh at rest: 31.6 C
• No whole shea SFC table published

What the two butters are, and the terms this page uses

Cocoa butter is the fat pressed from cocoa beans, the fat in chocolate, and its name on a cosmetic label, the INCI name, is Theobroma Cacao Seed Butter. It is sold natural, with a chocolate smell, or deodorised, and its grades and uses in balms are on the cocoa butter page.

Shea butter is the fat from the nut of the shea tree of the West African savanna, and its INCI name is Butyrospermum Parkii Butter. It is sold crude (unrefined) or refined, and the grades are compared on the shea butter page.

Five terms carry the argument, and the first one is the term the whole page turns on.

• Solid fat content, or SFC, is the share of a fat, by weight, that is still solid crystal at a given temperature, and the rest is liquid oil. A butter does not melt at one point but loses crystals bit by bit as it warms, so SFC is read as a curve. It is usually measured by pulsed NMR, a magnet-based test that tells solid from liquid fat, and the full account is on solid fat content.
• A triglyceride is a fat molecule, three fatty acids on a short backbone, and each one is named by three letters. StOSt (stearic, oleic, stearic, written SOS in many papers) is hard, while StOO (stearic, oleic, oleic, or SOO) is soft, and POP and POS are hard ones built with palmitic acid.
• A polymorph, or crystal form, is one of the ways the same fat can pack as it sets. Cocoa butter has six, and the one chocolate makers want is form V, also written beta 2. Form VI, or beta 1, is the more stable form it can turn into later, as explained on fat crystal polymorphism.
• Bloom, or fat bloom, is the pale grey or white film on old chocolate or an old cocoa butter balm, made of fat that has crystallised again at the surface in coarse crystals, which scatter light, and it is not mould and not rancidity.
• Grain is the small hard lumps you can feel in a balm, and in shea they are clumps of StOSt crystals that grew apart from the soft fat, as grainy shea butter explains.

Shea and cocoa butter side by side

Most pages on this question give each butter one melting point and stop there, and on that basis the two look almost the same. The table puts the figures that do differ in one place, drawing on one NMR study of cocoa butter, one study of crude shea and its fractions, a literature table of cocoa butter's crystal forms, one study of the two blended, and one shea data sheet.

The dashes in the shea column are not gaps in this page: a study of 37 crude shea butters from Burkina Faso, covered on the solid fat content page, found that their SFC profiles varied "depending on their origin and extraction processes", and published them as charts, and no open source found gives whole shea's SFC as a table, so this page quotes no figure for it.

A worked case: one tube, one summer pocket

Take a standard tube balm at 3:2:1, oil to butter to wax, which is 50 percent oil, 33.3 percent butter and 16.7 percent beeswax, as lip balm ratios sets out. On a 57 g batch that comes to 28.5 g of oil, 19.0 g of butter and 9.5 g of wax. Suppose the tube will live in a front trouser pocket in July and you are choosing between cocoa butter and shea.

Step one, the pocket temperature. A tube in a front pocket sits against the thigh, and in one study, the front of the thigh in 30 resting footballers measured 31.6 C by thermal camera, in a 24.5 C room. A summer day and a walk will push that up, so read the butters at 30 C and at 35 C.

Step two, cocoa butter's solid fat. Multiply the 19.0 g of butter by the NMR figures: at 20 C, 70.54 percent solid gives 13.4 g of crystal. At 30 C, 25.63 percent gives 4.9 g, at 35 C, 10.31 percent gives 2.0 g, and at 40 C there is none.

Step three, set that against the wax. The 9.5 g of beeswax melts at 62 to 65 C, as the beeswax page records, so all of it is still crystal in a pocket. At 30 C the cocoa butter adds about half as much solid as the wax again, and at 35 C about a fifth. So in this tube the wax is the frame at pocket heat, and cocoa butter is a useful extra at the low end of the range.

Step four, try shea in the same slot. There is no table to multiply, but the composition gives this: 19.0 g of crude shea at 42.1 percent StOO is 8.0 g of soft fat. The shea fraction made mostly of StOO melted at 25 C, so expect most of that 8.0 g to be liquid before the tube reaches your pocket. The other 8.9 g is the hard StOSt, which may hold some crystal at 30 C, and no figure says how much. The nearest thing to an answer is the blend study below: shea stirred into cocoa butter softened it, partly by dilution, which means shea was the less solid of the two.

Step five, the bloom check. Cocoa butter's form V melts across 30.0 to 34.5 C, and the 31.6 C thigh reading sits inside that range. So each day in the pocket melts part of the cocoa butter's crystals, and each evening on a cool shelf they set again in whatever form they can. That cycle is the condition bloom needs, and the tube may turn white on its surface, which is cosmetic and clears with a remelt.

On those figures, cocoa butter is the butter for this tube, and the wax is what decides whether it survives. If the tube goes soft at 35 C, cutting the butter will not help much, since even cocoa butter is about nine tenths liquid there, so move up the wax ladder instead, which balm melting in the heat sets out step by step.

Which one holds in a warm pocket

Why the melting points look the same

The common answer is that the two melt at about the same temperature, so it does not matter, and on paper the single figures do sit together. AAK gives its refined LIPEX Shea a slip melting point of 31 to 35 C by AOCS Cc 3-25, the open-tube test most butter sheets print: the temperature at which a column of set fat starts to rise in warm water. A crude Ghanaian shea melted at 32 C by a capillary tube test, AOCS Cc 1-25, and cocoa butter's form V melts across 30.0 to 34.5 C, in a table of published values gathered by Declerck and colleagues in 2021.

Those numbers come from different tests and cannot be ranked against each other, as melting point methods explains. But even read loosely, they say one thing, which is that both butters finish melting near lip temperature. What a melting point cannot say is how much of each butter is still solid on the way up, and that is the number a pocket tests.

What the solid fat figures say

Kamali and colleagues measured cocoa butter by pulsed NMR in 2019, as the control sample in an oleogel study, and it was 82.15 percent solid at 0 C, 70.54 at 20 C, 25.63 at 30 C, 10.31 at 35 C and 0 at 40 C. A second study, in 2026, came within two points at every temperature, as the solid fat content page shows.

That curve has a plateau and a cliff: cocoa butter barely changes from a cold room to a cool one, and then loses about 45 points of solid between 20 and 30 C. So a cocoa butter tube that feels firm on the desk will feel distinctly softer in a pocket, though it still has a quarter of its butter as crystal at 30 C.

Where shea sits

Shea's make-up explains why it holds less: Abdel-Razek and colleagues found crude shea to be 46.77 percent StOSt and 42.12 percent StOO. Cocoa butter, by NMR in Trapp's 2024 study, is "mostly made of POP, SOS, and POS", all hard triglycerides with two saturated fatty acids, so shea carries a large soft share that cocoa butter mostly does not.

The same shea study split the butter into its two parts, and the hard fraction, shea stearin, was 90.72 percent StOSt and melted at 36 C. The soft fraction, shea olein, was 72.66 percent StOO and melted at 25 C. Whole crude shea melted at 32 C, between the two, and a tube in a pocket is past the olein's melting point, so the soft share of whole shea adds little solid there.

A blend study points the same way: Rodríguez-Negrette and colleagues mixed shea into cocoa butter in 2019, and its abstract reports that "softening occurred due to both dilution effects and a slight eutectic formation". A eutectic is a mix that melts lower than either fat alone, as the solid fat content page explains for cocoa butter and coconut oil. Shea made cocoa butter softer, not harder.

The wax does the holding

The bigger point for a summer tube is how small both butters' share is at skin heat. At 35 C cocoa butter is 10.31 percent solid, and in the worked case, that is 2.0 g of crystal against 9.5 g of wax. Crude shea had melted by 32 C in its capillary test, so it will not do better.

So the choice of butter moves a tube's firmness on a shelf and in a mild pocket, but it does not decide whether the tube turns over in a hot bag, which is the wax's job: a few points of candelilla or carnauba alongside the beeswax, as the heat ladder on balm melting in the heat shows. If your tube is too soft even at room temperature, start with balm too hard or too soft instead.

Which one blooms

What bloom is in cocoa butter

Bloom is the cocoa butter fault, and it comes straight from chocolate, where Declerck and colleagues puts it plainly: cocoa butter in chocolate should crystallise in the beta 2 form, form V, to get snap, gloss and the right melting range, and "to avoid quality defects due to fat bloom". Form VI, the more stable form, melts higher, at 33.5 to 36.3 C, which is above a resting thigh.

Trapp and colleagues took the bloom off pralines kept at 20 C for weeks and found it was mostly POP, POS and SOS, the same hard fats as cocoa butter. The study also found that liquid oil from the nut filling moved through the chocolate shell and turned up in the bloom, and the picture is fat moving to the surface and crystallising again there, with oil from the filling joining it.

Why a pocket is the worst place for it

Put those ranges next to the pocket: form V melts between 30.0 and 34.5 C, and a resting thigh measured 31.6 C. A tube carried every day keeps crossing into the range where its normal crystals melt, and out of the pocket that fat sets again, slowly, on a cool shelf.

Partial melting followed by slow setting is the pattern the heat page links to bloom and grain. Nothing in the sources measures how many pocket days it takes, so this page gives no figure, but a tube that sits on a desk at 20 C is not in that range at all, so the same balm may stay glossy at home and bloom in a pocket.

Shea's version: grain

Shea does not get its own entry in the bloom studies read here, and its documented fault is grain, and the cause is the same family of fat. The hard StOSt sets first, and when cooling is slow, few crystal seeds form, so the StOSt grows into fewer, larger crystals in the liquid StOO. Over the following days those crystals coarsen until a fingertip can feel them.

So a pocket cycle that turns a cocoa butter tube white tends to turn a shea tube gritty instead. Neither butter is safe from warm and cool cycles, and they show the damage differently: cocoa butter on the surface, shea through the stick and on the lips.

What to do about it

Bloom and grain have the same prevention and the same cure: melt the whole batch fully, so no old crystal seeds survive, then cool it quickly, so many small crystals form at once rather than a few large ones. Pour and cooling temperatures are in pour temperatures, and why speed matters is in crystallisation and cooling rate.

If a tube has bloomed, it is still fine to use, since the film is fat, not spoilage. To clear it, remelt the tube fully and cool it fast again, but check first that the film is smooth, dry and odourless, since a fuzzy, coloured or smelly growth means water got in, which is a different problem.

Why "shea stops cocoa butter blooming" keeps coming up

The claim starts from something true in chocolate, where shea stearin, the hard fraction, is used as a cocoa butter equivalent. Abdel-Razek's paper describes it as rich in "symmetrical stearic-rich triacylglycerols" and says it is used in chocolate partly for "reducing fat migration and blooming".

But shea stearin is not the shea butter in a maker's tub, and the numbers show why. The stearin in that study was 90.72 percent StOSt and 4.75 percent StOO, against 46.77 and 42.12 for whole crude shea. Taking the soft half out is what makes stearin useful against bloom, and whole shea puts that soft half back in.

The one study found that blended whole shea into cocoa butter found the opposite of the claim. In chocolates made with 10, 20 and 30 percent shea in the fat, "the polymorphic transition from β2 to β1 occurred to a greater extent with increasing content of SB". That is form V, the form Declerck says chocolate needs to avoid bloom, turning into form VI. The same chocolates still "had good appearance" after a year at 18 C, so the extra change did not show as bloom at that steady temperature, but a lip balm in a pocket does not sit at a steady 18 C.

So do not add shea to a cocoa butter tube to stop bloom: add it, if you want it, for glide or for its own sake, and cool the batch fast either way.

Which one to choose, by job

If you can stock only one butter for summer lip tubes, cocoa butter gives more body per gram at pocket heat, and deodorised cocoa butter avoids the chocolate smell. Make the wax carry the heat, cool every batch fast, and keep a tube in your own pocket for a week before you sell any. For the broader picture of butters beyond the lip tube, see butters compared, and for a firmer butter than either, mango and kokum butter. The full method is in how to make lip balm.

What this answer does not cover

No study found has tested shea and cocoa butter side by side in a lip balm, in a pocket or anywhere else, and the holding ruling rests on NMR figures for pure cocoa butter after a quick chill, and on the make-up and fractions of one crude Ghanaian shea. Shea varies a lot by origin and processing, so a refined shea from another source may sit away from every shea figure here. Shea's solid fat at pocket heat is not published as a table, so the gap between the two butters cannot be given as a number.

The bloom ruling rests on chocolate: the crystal form ranges, the bloom analysis and the blend study were all done on cocoa butter or chocolate, not on a balm that is half liquid oil. The thigh figure is one group of 30 professional footballers at rest in a mild room, not a pocket in summer, and a pocket in sunshine or a parked car will be hotter, while the worked case is arithmetic on published figures, not a test of a real tube.

This page does not cover how either butter feels or tastes on the lips, how long it lasts there, or any claim about healing, and it does not say how much wax to add for a given climate. Hold a test tube at 32 C for an hour, as the heat page suggests, and carry one for a week before you scale up. If a tube cracks rather than softens, cracked and crumbly balm covers that fault.
