How to make a Charcoal Cleansing Balm

Long before charcoal turned up in beauty aisles, it was already trusted to pull things out of where they didn’t belong. Ancient Egyptian physicians used charred wood to treat wounds. Hospitals still keep activated charcoal on hand today to treat certain poisonings, because it’s so good at binding to substances and holding onto them. This trapping process is called adsorption. Charcoal has an enormous, porous surface area that acts like a molecular magnet, catching molecules against its surface rather than absorbing them the way a sponge would.

That same trapping action is what makes charcoal such an interesting ingredient to formulate with. In a cleansing balm, it adds a mild binding effect of its own, on top of the oil cleansing already happening underneath it. Oil cleansing runs on a simple bit of chemistry. You massage an oil or balm onto dry skin, and it dissolves the oil-soluble dirt, sebum, and makeup that build up throughout the day, because like dissolves like.

Put the two together, and you get a formula that’s as fun to make as it is to look at. Melted down, our butters and oils start out a warm gold. Stir the charcoal through, and the whole batch turns a deep, glossy black in seconds, one of those small moments in formulating that never quite stops being satisfying.

In this formula, we’ll show you how to make a charcoal cleansing balm that melts into the skin, lifts away makeup and daily grime, and leaves a soft, conditioned finish behind, while doubling as a genuinely useful introduction to anhydrous (oil-based) formulating. You’ll also see how butters, waxes, and oils behave together, and how just one small adjustment can change the finished texture.

What you’ll need to make a charcoal cleansing balm

Equipment

Here’s everything you’ll need to make a charcoal cleansing balm. You don’t need any complicated equipment or a professional lab setup to make it. All you need is:

• A digital kitchen scale to measure your ingredients
• Two heatproof glass beakers or jars (one for your butters, one for your oils)
• A glass stirring rod or a clean spoon to stir your mix
• A water bath (a saucepan with a few centimetres of water works well)
• Jars to package your finished balm

You’ll also need to wear disposable gloves and an apron, and tie your hair back before you start making this charcoal cleansing balm to keep everything hygienic. We also recommend wearing a face mask for this formulation since SCI is irritating to the airways if inhaled. Activated charcoal is also very fine, and you don’t want to breathe it in while you’re weighing or stirring it. It will also happily stain your countertop, your clothes, and your hands if you let it, so be sure to protect your clothes and work surface.

As for your formulation space, all you need is a clean and clear counter space that you wipe down before starting, and sanitise with 70% isopropyl alcohol or ethanol.

You can easily find all of this equipment online or in kitchenware stores, if you don’t already have it at home. Otherwise, you can also find it on our Formula Botanica Amazon page.

Ingredient shopping list

To make your cleansing balm, you’ll need:

• Cupuaçu butter — in the same botanical family as cocoa butter, but softer and lighter on the skin. Its balanced fatty acid profile makes it deeply nourishing without feeling heavy.
• Cocoa butter — gives the balm its solid structure at room temperature and adds a rich, conditioning feel as it melts into the skin.
• Myrica wax — a plant-derived wax made from myrica berries. It firms up the texture and helps the finished balm glide smoothly across the skin.
• Lecithin — enhances texture and feel.
• Passionfruit seed oil — brings antioxidants to the formula along with a subtle, fruity scent.
• Macadamia nut oil — known as a vanishing oil, since it absorbs into the skin quickly without leaving a greasy residue behind.
• Activated charcoal powder — disperses through the oil phase to give the balm its colour. Its porous surface can adsorb some oil-soluble impurities, helping to lift excess sebum and certain environmental pollutants from the skin. It won’t fully dissolve, which is expected.
• Vitamin E (Tocopherol) — an antioxidant that also helps slow down rancidity in the oils and butters over the balm’s shelf life.
• Alpha-bisabolol — a naturally occurring compound derived from chamomile and candeia trees. It’s valued in skincare for its anti-inflammatory and calming properties, which make it a popular choice for sensitive or easily irritated skin.
• Cedarwood essential oil and sweet orange essential oil — together they build an earthy, citrus scent. Swap either for a different essential oil blend if you’d prefer a different scent profile.
• Sodium Cocoyl Isethionate (SCI) powder — optional. A gentle, coconut-derived surfactant that helps the balm emulsify with water, allowing it to rinse away more readily and leave less oily residue on the skin. More on this in the method below!

How to make a charcoal cleansing balm, step-by-step

• Makes: 100g
• Level: Beginner-friendly
• Estimated time: 20 minutes, including melting time
• Method: Melt and pour, water bath required

Step-by-step method:

Here’s how to make a charcoal cleansing balm, from melting your butters through to pouring your finished batch.

• Step 1: Melt the butters, wax, and lecithin (Phase A)

Weigh your cupuaçu butter, cocoa butter, myrica wax, and lecithin into a heatproof beaker, taring the scale after each addition. Place the beaker into your water bath and let everything melt together slowly until it reaches 60-65°C.

• Step 2: Blend the oils and charcoal

While Phase A melts, weigh your passionfruit seed oil and macadamia nut oil into a second beaker. Add the activated charcoal powder and stir it through. It won’t dissolve, but dispersing it now stops it from clumping once it meets the butters.

• Step 3: Combine and add the finishing touches

Once Phase A has fully melted, remove it from the water bath and let it cool to 45-50°C.

Want a version that rinses away completely? This is the point where you’d add your SCI. Weigh out 2g of Sodium Cocoyl Isethionate powder and add it to your melted ingredients. It disperses into the mixture, and it’s what changes the balm from a rich, conditioning cleanser into one that emulsifies with water and washes off cleanly. Since SCI adds weight, reduce the macadamia oil to 19.95g to accommodate the additional ingredient. If you’re skipping the SCI for a final formulation that leaves a soft, conditioned finish behind, increase your macadamia oil to 21.95g.

Pour the oil and charcoal blend from Phase B into it and stir. You’ll see the mixture turn from golden to a deep, even black.

Add your vitamin E, alpha-bisabolol, cedarwood essential oil, and sweet orange essential oil, and stir well.

• Step 4: Pour and package

Stir continuously as the balm cools so the charcoal (and SCI powder, if you’ve added it) doesn’t settle at the bottom of the beaker. Once the balm has cooled slightly but is still pourable, pour the balm into your jars and leave it to set.

Now you know how to make a charcoal cleansing balm! We recommend trying both versions so you can see which formulation you prefer.

Using your cleansing balm

To use your cleansing balm, massage a small amount into dry skin. Add a splash of warm water and work it in. What happens next depends on which version you made.

The version made without SCI turns into a rich oil that you can wipe away with a warm, damp cloth. It leaves a light, conditioning residue behind, which makes it a lovely first step in a double cleanse, or a treat on its own for dry or mature skin.

The version made with SCI turns milky and rinses away completely with water, leaving skin feeling clean rather than coated. That makes it a better fit if you have oilier skin, or if you want a balm you can use as your only cleanser rather than as the first step of a double cleanse.

Both versions are suitable for all skin types. Store either balm in a cool, dry place, and it will keep well for months.

Notes & customisation tips from the Formula Botanica team

Cleansing balms are one of the most forgiving anhydrous formulas you can make, and small tweaks change the finished texture a surprising amount. A few things worth knowing as you experiment:

Avoiding a greasy finish. Balance heavier butters with dry, fast-absorbing oils like macadamia or passionfruit seed oil, the way this formula does. A touch of lecithin also improves skin feel without emulsifying the balm. Charcoal and clays help here too, since both reduce greasiness while adding a creamier texture and a light, gentle exfoliation as you massage the balm in.

Working with charcoal. Activated charcoal disperses rather than dissolves, so keep stirring through the cooling stage to stop it settling. It’s completely harmless on skin, but it will mark fabric and worktops, so glove up and protect your space before you start.

Storage and packaging. Because this balm is anhydrous, it’s naturally more resistant to microbial contamination than a water-based product, provided you keep water out of the jar. If you’re using a jar, store it somewhere cool and dry, keep the lid closed between uses, and scoop with a small spatula rather than your fingers to avoid introducing moisture.

Making it your own. The essential oil blend, the charcoal amount, and the SCI addition are all easy to adjust. Leave the charcoal out entirely for a paler, more neutral balm, or swap the essential oils for a scent you prefer.
