Have you ever whipped up an utterly decadent body butter, only to find it transformed into a hard, crumbly brick when left overnight? Or perhaps you were whipping up a gorgeous blend of butters that suddenly collapsed into soft gloppy mess? Whipped body butters are absolutely decadent, but they can also be a bit finicky. Today we’re looking at the common reasons why your body butters aren’t whipping (or staying whippy) and how to fix that!

What is whipped body butter?
For the purposes of this article, whipped body butter is an anhydrous (water-free) skin moisturizer. It is a soft solid that has been whipped to incorporate air, resulting in a light and fluffy finished formulation that is softer and melts faster than un-whipped body butters.
How do you know your body butter isn’t whipping?
There are two main “not whipping”/”that’s not what I wanted” categories when making whipped body butter
The first one is obvious straight away as you are trying to whip the butter: you are whipping away with your beaters and the body butter is just pooling at the bottom of the bowl instead of getting all light and fluffy.
The second whippy flop takes a couple hours to a couple days to set in; this is when you come back to use that beautiful butter you whipped up earlier and it’s seized and gotten all hard and crumbly. Bummer 😕
Why isn’t it whipping?
There quite a few different reasons a whipped body butter can rebel; let’s look at the different causes (and fixes). These reasons can be broadly separated into formulation and manufacturing/technique.
The fat blend is too soft and can’t hold air in it.
In order to be whip-able, your fat blend needs to be a soft solid at room temperature. If it’s so soft that it tends towards liquid, you won’t be able to whip any air into it. If your body butter liquifies in the bottom of the bowl from the get-go, you need to increase the percentage of solid ingredients and reduce the percentage of liquid ingredients.
“Too soft” is very dependent on the ambient temperature where you live; you may encounter this with formulations created by other formulators if you live somewhere warmer than the original formulator does.

The fat blend is too hard.
This is generally the problem when your body butter becomes hard and crumbly when left to sit. I’ve found you can whip up almost any mixture of solid butters if it’s solid enough; the challenge is if it stays soft and whippy. Just as with “too soft”, “too hard” is very dependent on the ambient temperature where you live. What is “too hard” for me might be “too soft” for you if you live somewhere quite a lot warmer than I do (and vice versa!).
There are two sub-categories of “too hard”: too high a concentration of solid butters/ingredients, and the wrong kind of solid butters/ingredients.
In order for whipped body butters to be soft, they need to be made up of mostly soft, squishable butters—butters that are malleable at room temperature. Popular choices include shea butter, mango butter, murumuru butter, and cupuaçu butter. That soft butter (or blend of soft butters) is then softened to a just right point with liquid ingredients like liquid oils and esters. It needs to be solid enough to whip, but soft enough to stay soft and whippy. If the solid base hasn’t been softened enough (and “enough” is very dependent on ambient temperature!), the whipped body butter will seize up when left to sit. If this happens you’ll need to shift the balance of the formulation to include a higher percentage of liquids and a lower percentage of solids.

If your fat blend contains a high concentration of ingredients that are brittle at room temperature, like cocoa butter or waxes, that could be why your body butter is getting hard and crumbly when left to sit. Brittle-hard butters and ingredients will want to revert to being brittle-hard, and if there’s enough of them in your formulation they’ll make your body butter brittle and crumbly as they do that. It’s definitely possible to make whipped body butters that contain brittle ingredients, but you’ll need to experiment to find out how much your formulation can handle while still maintaining its light, whippy consistency. Check out my Chocolate Cherry Whipped Body Butter for an example.
The mixture is warming up too much as you whip it
The friction of whipping warms the butter; this is why it’s possible to whip up a too-hard fat blend and have it seem perfect, only to seize up when left at room temperature. This is also why your body butter whipping might be going brilliantly and then—whomp—your fluffy body butter collapses into a sloppy soft liquid.
This friction and heat is is why many whipped body butter formulations include some sort of cooling in the process, often in the form of a freeze-whip-freeze-whip cycle. You melt the fat blend together, freeze the bowl for ten minutes or so, and then alternate between whipping for a few minutes, freezing for a few minutes, whipping for a few minutes, etc. until the butter is all light and fluffy. The frequent stops in the freezer keep the butter from getting so warm that it melts on you as you’re working with it.
The longer you whip a butter, the more the whipping process will warm it up. The larger a batch of body butter is, the more whipping time it will require. This can mean that the process used for a smaller batch of body butter doesn’t work for a larger batch of body butter. I’ve found that 30–50g batches of body butter often whip up beautifully with just one stop in the freezer after melting; they’re small enough that they don’t need a lot of whipping time, and the coldness of the bowl after a short stay in the freezer keeps the body butter from getting too warm as you work. However, if you scale that same formulation up, you’ll likely need to incorporate some more cooling because your whipping time will be longer. The freeze-whip-freeze method works; you can also try placing your bowl in an ice bath and whipping it in there!

You are cold processing a formulation designed to be hot processed (or vice versa)
Melting your fats together vs. simply whipping them together at room temperature can result in fat blends with surprisingly different levels of hardness. If the formulation you’re following was designed to be cold-processed and you opt to melt everything together first, that might not work out well at all. This one isn’t a sure flop, but if you’ve made this swap and the body butter isn’t working out, this might be why.
You used a refined butter instead of an unrefined butter (or vice versa)
This is another “not a sure flop, but if you’ve done this and the formulation isn’t working out, this might be why” thing.

How can you fix it?
Ensure the formulation is mostly butters that are soft at room temperature
Your un-whipped fat blend needs to be soft at room temperature; if it’s too hard, your body butter won’t stay soft and whippy. If your formulation features lots of brittle/hard solid ingredients try reducing the percentage of those for ingredients that are soft solids. It doesn’t have to be 50%+ soft butters by any means (it varies with ambient temperature, the specific butters, and whipping methods)—but there should be soft butters, and those butters will play a meaningful role in the experience of the finished formulation.
Tweak the balance between the soft solids and the liquids
The perfect balance between soft solid and liquid will vary with ambient temperature and the specific butters you’re working with. If your fat blend is too soft (and it’s not because it’s warming up too much while whipping), adjust the fat blend to include more soft butters and less liquid oils. If your butter is getting too hard when left to settle, adjust the fat blend to include more liquid oils and less soft butters.
Give it time
If you aren’t sure, give it time. Whip and wait. I never declare a whipped body butter formulation “done” until it’s proved that it stays soft for days at room temperature. It can also be helpful to whip up a few different ratios so you can compare them side-by-side, as I did here.
Experiment with different cooling methods
If you find your butter is getting too soft as you’re whipping it, experiment with different ways to keep it cool while you work.
Thanks for your awesome work!
If I add some aloe vera gel or rose water to my oil body butter and whip, would it work well?
You can’t—that’ll split. Please look at my emulsified body butter formulations + read this to learn more. Happy making!
Hello, your post is awesome, thank you for the info!
My whipped body butter, with the same recipe, sometimes I have 7 jars and sometimes I have 5. Why do you think this happens? I follow the same steps every time.. I just don’t get it! I appreciate any help!
Try filling by weight—I’d bet you whip more air into the mixture on some occasions 🙂
Hi Marie. First let me tell you that I adore your website, all the info and your scientific approach to this craft. I’m still a beginner but I’ve already learned tons and upped my skincare game significantly with your recipes and advice. Thank you!
Now, though I’m not planning to whip any butters yet, there’s something I’ve been wondering about. Years ago I was gifted a natural body butter that was supposed to be whipped, but I can’t recall it being so (I suppose temperature changes killed it). It also left a horrible greasy film on my skin, which meant that it ended up sitting on a shelf way past its expiry date until I got rid of it. I saved the tin it came in though so that I could reuse it. Now here’s the mistery: the tin is super difficult to clean. I just tried again yesterday and there are still some specks of hard stuff stuck on the it. It looks like the product had crystallized.
Here are the ingredients: shea butter, coconut oil, hemp oil, linseed oil, argan oil, cornstarch, essential oil blend (orange, tangerine, ginger root), vitamin E. I suspect the starch, but the whole thing was expired by 3 or 4 years when I chucked it out and I don’t know what sort of reaction might have happened there. Do you have any idea?
I only use avocado butter and avocado oil then add in Frankincense for my body butter but I don’t know the exact amounts to use so my end result is hit and miss on it being fluffy. Could you recommend exact amounts?
