Mango butter vs shea butter for lip balm: which is firmer, and which goes grainy?

A refined mango butter can set a much firmer tube than shea, but only if its data sheet says so. Grain, smell and shelf life checked against two sheets and three studies.

For a firmer lip balm tube, choose the butter with the higher slip melting point on its data sheet, and that is usually a refined mango butter. One refined mango butter sheet gives a slip point of 45 to 55 C, while one refined shea sheet gives 31 to 35 C by the same test. But mango is not firmer by nature, since fat from a soft mango variety such as Kent has less stearic acid than crude shea, and in the lab it stayed liquid for five hours at 20 C. Nor is mango grain-proof, because it is built from the same two kinds of fat molecule as shea and ends in the same stable crystal form. Refined, neither butter smells of much, and neither has a shelf life of its own: the number belongs to the lot.

• Slip point: mango 45-55 C, shea 31-35 C (one sheet each)
• Iodine value: 40-55 against 62-72
• StOSt: mango 23.9-45.9%, crude shea 46.8%
• Soft to hard fat: mango 0.3-1.0, shea 0.9
• Both end in the beta form
• Shelf life: 12 months minimum against 3 years maximum

What mango butter and shea butter actually are

Mango butter is the fat from the kernel inside a mango stone. Its INCI name, the name on a cosmetic label, is Mangifera Indica Seed Butter, and food scientists call the same material mango kernel fat. The kernel is lean: across seven Ivorian varieties it held 4.9 to 9.6 percent fat by dry weight. No fruit flesh is involved, so it does not smell of mango, and how it is used in balms is on the mango and kokum butter page.

Shea butter is the fat from the nut of the shea tree, which grows across the West African savanna. Its INCI name is Butyrospermum Parkii Butter, and it is sold crude (unrefined) or refined, bleached and deodorised. The grades are compared on the shea butter page.

Four more terms carry the argument.

• A triglyceride is a fat molecule, made of three fatty acids on a short backbone, and a butter is a mix of many of them, each named by three letters. StOSt (stearic, oleic, stearic, written SOS in some papers) is hard, and StOO (stearic, oleic, oleic) is soft.
• A polymorph is one of the crystal forms the same fat can set in: alpha is the loosest, then beta prime, then beta, the tightest and most stable. The full account is in fat crystal polymorphism.
• Grain is the small hard lumps you can feel in a balm. In shea they are clumps of beta StOSt crystals that grew apart from the soft fat, as grainy shea butter sets out.
• The slip melting point is the temperature at which a column of set fat in an open glass tube starts to rise when warmed in water. The test is AOCS Cc 3-25, and it is the melting figure most butter data sheets print. Other tests give other numbers for the same fat, as melting point methods explains.

Mango and shea, side by side

Most pages on this question say mango is firmer, less grainy and odourless, and that one butter keeps longer than the other, but none of them names a lot, a test or a study. The table below puts the published figures in one place. It draws on one commercial data sheet for each butter, two studies of mango kernel fat from Côte d'Ivoire, and one study of crude Ghanaian shea.

Two rows in that table are not on any single page elsewhere. Both sheets use the same slip point method, so the gap of 10 to 20 degrees is real for those two products, and the ratio row shows that mango does not sit on one side of shea but spans it.

A worked case: two data sheets, one lip balm

Suppose you make a standard tube balm at 3:2:1, oil to butter to wax. As lip balm ratios sets out, that is 50 percent oil, 33.3 percent butter and 16.7 percent wax, or 28.5 g, 19.0 g and 9.5 g on a 57 g batch. Your butter is a refined shea like AAK's LIPEX Shea, and you are thinking of swapping in a refined mango like Fratelli Parodi's PARYOL 468 MG/R. Read the two sheets before you weigh anything, in five steps.

Step one, the slip melting point and its method: the shea sheet gives a typical 31 to 35 C by AOCS Cc 3-25, and the mango sheet specifies 45.0 to 55.0 C by the same method. So the mango stays solid well above lip temperature while the shea starts to give way close to it, and on these figures the mango will set the firmer tube.

Step two, the iodine value: a lower iodine value means a more saturated, harder fat, and the mango sheet's 40.0 to 55.0 against the shea sheet's 62 to 72 agrees with step one. The seven lab-extracted mango kernel fats measured 42.7 to 60.4, still below the shea sheet.

Step three, anything that predicts grain: neither sheet lists triglycerides, and the mango sheet's stearic acid range of 30.0 to 45.0 percent covers both the slow, soft mango fats and the fast, hard ones described below. So cool it the way you would cool shea.

Step four, the odour line: the shea sheet says "low vegetable butter odour", while the mango sheet has no odour line at all, only a colour limit of Gardner 4.0, so neither sheet gives you a smell difference to pay for.

Step five, the shelf life wording: the mango sheet says "12 months minimum in cool conditions in unopened container". The shea sheet gives a "recommended maximum storage time" of 3 years from production, unopened, at 15 to 20 C or below. One is a floor and one is a ceiling, so you cannot rank them, but you can compare the peroxide limit over that time: 10.0 for the mango and 5 for the shea.

Swapping 19.0 g of this shea for 19.0 g of this mango will give a harder tube, but no source found measures how much harder. Make the first batch with the wax unchanged, and if it drags or snaps, take the wax down one point at a time, which is 0.57 g on this batch. How to compare two sticks fairly is in measuring balm hardness.

Which gives a firmer tube

The common answer is that mango is firmer because it has more stearic acid, but on stearic acid the two butters overlap. The Parodi mango sheet allows 30.0 to 45.0 percent, Abdel-Razek's crude shea measured 43.5, and Kouassi and colleagues found 30.3 to 48.3 across seven Ivorian mango varieties.

What does separate them is how much of that stearic acid sits in the hard triglyceride, StOSt. Crude shea measured 46.8 percent StOSt, while the seven mango kernel fats measured 23.9 to 45.9. So the hardest mango fats match crude shea, and the softest have about half as much.

Kouassi's 2024 study shows what that means. It melted three of the fats at 80 C and cooled each to 15 or 20 C:

• Djakoumankoun, with 45.8 percent StOSt and 48.3 percent stearic acid, set fastest at both temperatures.
• Brooks, with 37.0 percent StOSt and 42.5 percent stearic acid, set second.
• Kent, with 26.3 percent StOSt and 35.1 percent stearic acid, had not crystallised at 20 C after 4 hours of the solid fat test or 5 hours of the crystal tests. At 15 C it had the lowest solid fat content, 30 percent.

A balm built on the Kent fat would lean on its wax far harder than one built on Djakoumankoun fat. Solid fat content, the share of a fat that is solid at a given temperature, is explained in solid fat content.

No sheet or source found says which varieties a commercial mango butter comes from, so the slip point is the number to trust: a slip point of 45 to 55 C cannot come from a fat that stays liquid at 20 C.

Which one goes grainy

The common answer is that shea goes grainy and mango does not, but the two are built the same way, so the risk is shared. Grain in shea starts with two triglycerides that do not crystallise well together. The hard StOSt sets first, and when cooling is slow, few crystal seeds form. The StOSt then grows into fewer, larger crystals in the still-liquid StOO, and over the following days those crystals turn to the beta form and coarsen until a fingertip can feel them. That is the mechanism set out on the grainy shea butter page.

Mango kernel fat has the same make-up. Kouassi's 2024 paper names its three main triglycerides as StOSt, StOO and StLSt (stearic, linoleic, stearic), and concludes: "Due to their high StOSt content, the three investigated samples are β-3L tending." Beta is the stable form, just as in shea, so both butters head for the crystal form behind grain.

The ratio that places mango against shea

The useful number is how much soft fat there is for each part of hard fat. Kouassi gives the StOO to StOSt ratio for the three mango varieties as 0.3 for Djakoumankoun, 0.6 for Brooks and 1.0 for Kent. Abdel-Razek's crude shea measured 42.12 percent StOO and 46.77 percent StOSt, which works out at 0.9.

So a Kent-type mango has about as much soft fat per unit of hard fat as crude shea, while a Djakoumankoun-type mango has about a third as much. Mango is not one point on the grain scale: it runs from well below shea to level with it.

The microscope work shows the same split: after 90 minutes at 20 C, the Djakoumankoun and Brooks fats had formed urchin-shaped crystal clusters in "substantial" liquid. The Kent fat formed nothing in 5 hours, and after 24 hours it held disc-shaped crystals with "a high proportion of liquid phase". Few crystals growing slowly in plenty of liquid is the pattern the grainy shea page links to coarse grain.

How fast mango reaches its stable form

In the lab, mango did not linger in its looser forms. At 15 C, the Brooks fat went from alpha to beta prime after about 15 minutes, and after 24 hours all three fats had beta crystals. At 20 C, after 24 hours, Kent was beta, Brooks was beta with traces of beta prime, and Djakoumankoun was a mix of the two. The authors note that more liquid fat speeds the change by letting the molecules rearrange.

So a mango balm, like a shea balm, can look smooth on the day you pour it and still change later, which is why a sample should be kept a week or more before you judge it. How cooling speed sets crystal size is in crystallisation and cooling rate.

What to do about it

A high-StOSt grade like the Djakoumankoun fat would be the safer butter, but no data sheet will tell you that you have one, so treat mango exactly as you treat shea. Melt the whole batch fully and hold it hot so that no crystal seeds survive, then cool it quickly so that many small crystals form at once, at the temperatures in pour temperatures. If a mango balm does grain, the rescue on the grainy shea page works the same way, because the crystals melt the same way.

Which one smells

The common answer is that mango is odourless and shea smells, and the refining step explains most of that difference. In a laboratory refining trial, two crude shea butters were reddish with a strong odour, and after refining they were pale and odourless. The figures for each step are on refined vs unrefined shea butter. AAK describes its refined LIPEX Shea as a "white, creamy butter with a low vegetable butter odour".

The mango sheet read here is a refined grade, and it sets a colour limit but no odour limit. No source found describes the smell of unrefined mango kernel fat. The 2023 Kouassi study did measure colour: the seven lab-extracted fats ran from light pale yellow to dark golden yellow, and the darkest, Amelie, had the most carotenoids, at 42 ppm.

So put refined mango against refined shea, where the sheets give no smell gap to choose on. If your lip balm must taste of nothing, the grade matters more than the plant: buy refined, and smell each new lot before you use it.

Which one keeps longer: the shelf life claims

Pages on this question give either butter one, two or three years without naming a test, a lot or a storage temperature. The data sheets make promises, not predictions: The Parodi mango sheet promises at least 12 months unopened in cool conditions, and over that time it lets the peroxide value, a measure of the first products of rancidity, rise from 5.0 or less at arrival to 10.0 or less. The AAK shea sheet allows up to 3 years unopened at 15 to 20 C or below, while holding the peroxide value at 5 or less and the acid value at 1.0 or less. Neither sheet says anything about an opened butter melted into a lip balm.

The lab tests say lot and grade matter more than species: The Rancimat bubbles hot air through a fat and times how long it takes to break down, so longer means more stable. At 110 C, Abdel-Razek's crude shea lasted 11.5 hours, and AAK gives a typical 45 hours for refined shea on an AOCS version of the same test. Kouassi's seven crude mango kernel fats lasted from 18.6 to 112.4 hours at 110 C, so the best variety outlasted the worst six times over.

Those hours do not convert to months on a shelf, but they do show that the spread inside mango is wider than the gap between mango and shea. A claim that "mango keeps longer than shea" picks one lot of each and calls it a rule.

The crude shea also arrived with 12.24 percent free fatty acids, against 0.9 to 4.6 percent in the lab-extracted mango fats. Free fatty acids mark a fat that has started to break down, and refining removes them, which favours buying refined of either butter.

Why "mango is firmer and never grainy" keeps coming up

Both halves of the claim start from something true. A maker who swaps in a grade like Parodi's will see a harder tube, and the error is turning one grade's figure into a fact about the plant. Mango is also prized in food for being like cocoa butter: Kouassi notes that mango kernel fat is one of six vegetable fats allowed in cocoa butter equivalents under EU Directive 2000/36/EC, fats chosen for setting in a stable, even crystal form. Yet the same paper warns that "special care should be taken" because "compositions and polymorphic behavior differ among the varieties", a caution that applies to a lip balm too.

Which one to choose, by job

If you can stock only one butter for lip balm, a refined mango with a stated slip point gives more firmness per gram, and you can read that off the sheet. If you want the unsaponifiable fraction that shea is often bought for, mango does not replace it, a trade covered on butters compared. Either way, make the balm the same way: melt fully, cool fast, and wait a week before you judge the texture. The full method is in how to make lip balm, and a plant-only version is in vegan lip balm.

What this answer does not cover

No study found has tested mango and shea butter side by side in a lip balm: the firmness ruling rests on one data sheet for each butter, from two suppliers, and the grain ruling rests on crystal studies of the pure fats, not of finished balms. Kouassi's papers measured how fast the fats set and which crystal form they reached, not grain, feel or hardness.

The mango fats in both Kouassi studies were extracted in the lab with hexane from sun-dried kernels of named Ivorian varieties, so they are not commercial mango butter. The shea study used one crude Ghanaian lot and its refined fractions, and other origins, varieties and refiners can sit outside every figure here, and shea itself varies widely by tree and region, as tallow vs shea butter shows.

This page does not cover how each butter feels on the lips, how long it lasts there, or any claim about healing, and it does not say how much wax to remove when you swap. Confirm the slip point, peroxide value and production date for your own lot, and test a small batch before you scale up. If a balm turns out too hard or too soft, balm too hard or too soft covers the fixes.
