How Cocoa Butter Is Made — And What Deodorising Really Means
From pod to press to your formulation — a complete guide to how cocoa butter is produced, what happens during deodorisation, how to choose between natural and deodorised, and how to use it in soap, balms, and skincare.
Cocoa butter is one of the most iconic ingredients in natural cosmetics — its rich, velvety texture, characteristic chocolate aroma, and skin-nourishing fatty acid profile have made it a staple in soap, lip balm, body butter, and skincare for centuries. But not all cocoa butter is the same. Understanding how it is made — and what deodorisation actually involves — helps you choose the right version for every application and formulate with confidence.
What Is Cocoa Butter?
Cocoa butter (INCI: Theobroma cacao (Cocoa) Seed Butter) is a natural, edible fat extracted from the seeds of the Theobroma cacao tree — the same tree that produces chocolate and cocoa powder. The name Theobroma means "food of the gods" in Greek, reflecting how deeply the cacao plant has been valued across human civilisations for thousands of years.
At room temperature cocoa butter is a firm, pale yellowish-white solid with a characteristic mild chocolate aroma. It melts close to body temperature — around 34–38°C — which is exactly why it feels so luxurious on skin, melting on contact and absorbing smoothly without a heavy or greasy residue.

How Cocoa Butter Is Made: From Pod to Press
Cocoa butter production is a multi-stage process that begins with a fruit on a tropical tree and ends with a refined cosmetic ingredient. Each stage affects the quality and character of the finished butter.
Harvesting the Cocoa Pods
Cocoa pods grow directly from the trunk and main branches of the cacao tree in tropical regions across West Africa, South America, and Southeast Asia. Each pod contains 20–50 cocoa beans embedded in a white, sweet pulp, and is harvested entirely by hand using machetes. A single cacao tree produces only enough pods for approximately 1kg of finished cocoa butter per year — making it a labour-intensive and relatively precious raw material.
Fermentation — The Critical Flavour Step
Scooped from the pods, beans and pulp are heaped into wooden boxes or covered with banana leaves and fermented for 5–7 days. This is the most important step in cocoa production. Yeasts and bacteria break down the sugary pulp and trigger complex biochemical changes inside the bean that develop the precursor compounds for chocolate's characteristic aroma. Without fermentation, cocoa beans would have a flat, astringent flavour and no chocolate character in any finished product — including cocoa butter.
Drying
After fermentation, beans are spread on raised beds and sun-dried for 1–2 weeks, turned regularly to ensure even drying. Moisture is reduced from approximately 60% down to under 8% — essential for preventing mould and ensuring safe storage and shipping. Sun drying is preferred over mechanical drying as the slower process allows additional mild fermentation and oxidation that continues developing the aroma profile.
Roasting
Dried beans are roasted at 120–160°C. Roasting triggers the Maillard reaction — the same process responsible for the browning of bread and coffee — developing the deep chocolate flavour from the amino acid and sugar precursors created during fermentation. It also loosens the outer shell for easier removal. The temperature and duration are carefully controlled; cosmetic-grade cocoa butter may use different roasting parameters than chocolate-grade beans.
Winnowing and Grinding to Cocoa Liquor
After roasting, the beans are cracked and winnowed — air separates the lighter papery husks from the heavier cocoa nibs. The nibs contain approximately 50–55% cocoa butter by weight. They are then ground in stone or steel mills into a thick paste called cocoa liquor (also known as cocoa mass or chocolate liquor — despite the name, no alcohol is involved). This paste is the starting material for both chocolate and cocoa butter extraction.
Hydraulic Pressing — Separating Butter from Powder
The cocoa liquor is loaded into large hydraulic presses operating at pressures up to 400 bar. Under extreme pressure, the liquid fat (cocoa butter) is forced out of the solid cocoa mass, collected, filtered, and cooled into solid blocks. The remaining compressed cake of cocoa solids is ground into the cocoa powder used in baking and cosmetics. Expeller pressing — a cold-pressing alternative — produces a slightly more aromatic butter with better retention of natural antioxidants, though at higher cost. Both methods produce cosmetically excellent cocoa butter.
Filtration, Tempering and Solidification
The freshly pressed butter is filtered to remove cocoa solid particles, then tempered — a controlled cooling process that ensures the correct crystal structure forms as the butter solidifies. Properly tempered cocoa butter snaps cleanly, has a uniform texture, and melts smoothly. At this point it is natural cocoa butter — pale golden, with a distinct chocolate aroma. If it is to be deodorised, it proceeds to the final stage.
What Is Deodorisation — and How Does It Work?
Deodorisation removes the volatile aromatic compounds responsible for cocoa butter's chocolate scent. Critically, it is a physical process — not a chemical one. No solvents, chemicals, or additives are used. The butter's fatty acid profile, moisturising properties, and functional characteristics remain completely unchanged.
"Deodorisation removes only the scent molecules from cocoa butter — nothing else. The skin-nourishing fatty acids, antioxidants, and melting behaviour are all retained exactly as in natural cocoa butter."
The Three Stages of Steam Deodorisation
The cocoa butter is loaded into a stainless steel vessel and the chamber is placed under deep vacuum — typically below 2–5 mbar. The vacuum dramatically lowers the boiling points of volatile compounds, allowing them to be removed at much lower temperatures than would otherwise be required. This protects the butter's nutritional and functional compounds from heat damage during the process.
Dry steam is injected into the heated butter under vacuum. The steam acts as a carrier — it physically lifts and carries the low-boiling volatile aromatic compounds (aldehydes, ketones, and short-chain esters responsible for the chocolate scent) out of the fat. This is essentially steam distillation in reverse — the steam removes rather than captures the volatile fraction.
The steam and volatile compounds exit the chamber and pass through condensers where the volatile fraction separates and is discarded. The remaining fat — now deodorised — is cooled under controlled conditions and solidified. The result is a near-white, neutral-scented butter that is otherwise chemically and physically identical to natural cocoa butter.
What is removed vs what stays: Deodorisation removes volatile aldehydes (2-methylbutanal, 3-methylbutanal), volatile ketones, and short-chain esters that create the chocolate scent. It retains all fatty acids (stearic, oleic, palmitic), all tocopherols (vitamin E), polyphenols, phytosterols, and the SAP value and melting behaviour are completely unchanged.
Natural vs Deodorised: Which Should You Choose?
Both versions are excellent — the right choice depends entirely on your formulation goals. Neither is superior in terms of skin performance. The decision is purely about scent and colour compatibility.
The Fatty Acid Science: Why Cocoa Butter Performs So Well
Cocoa butter's exceptional performance in soap and skincare is explained by its fatty acid composition — specifically its unusually high stearic acid content, which is rare among plant-based fats.
Most plant butters contain 5–15% stearic acid. Cocoa butter contains 35% — more than twice the level of shea butter. This is responsible for its firm, snapping texture at room temperature, its outstanding bar-hardening effect in soap, and its ability to form a skin-protective occlusive film. The high saturated fat content also gives cocoa butter one of the longest shelf lives of any cosmetic butter — 2–5 years properly stored.
- Tocopherols (Vitamin E): Natural antioxidants that protect against oxidative rancidity and provide antioxidant skin benefits. Fully retained through deodorisation.
- Polyphenols: Including epicatechin and procyanidins — the same antioxidant compounds found in dark chocolate. Present in higher concentrations in minimally processed cocoa butter.
- Phytosterols: Beta-sitosterol and stigmasterol — plant sterols with anti-inflammatory properties that support the skin's barrier function. Retained through deodorisation.

Working with cocoa butter in CP soap: Cocoa butter has a high melting point (~35°C) and can re-solidify in your oil blend as temperatures drop. Melt it completely and combine with other oils while both are warm (above 40°C). If it re-solidifies before you are ready to add lye, gently re-warm the oil blend. Alternatively, add cocoa butter at trace as a superfat — this ensures it remains as free conditioning fat in the finished bar and eliminates the re-solidification risk entirely.
Frequently Asked Questions
What is the difference between natural and deodorised cocoa butter?
Natural cocoa butter has a mild chocolate scent and pale golden colour. Deodorised cocoa butter has been steam distilled to remove the volatile aromatic compounds, resulting in a neutral scent and lighter colour. Both versions have an identical fatty acid profile, SAP value, skin performance, and shelf life. The choice is purely about scent and colour compatibility with your formulation.
Does deodorisation affect the quality of cocoa butter?
No. Deodorisation is a physical steam distillation process that only removes volatile aromatic compounds. The fatty acid profile, melting point, tocopherols, phytosterols, and all skin-nourishing properties are completely retained. Deodorised cocoa butter performs identically to natural cocoa butter in every soap and skincare application.
What is the SAP value of cocoa butter for soap making?
Cocoa butter has a NaOH SAP value of 0.137 and a KOH SAP value of 0.194. These values apply to both natural and deodorised versions. Always verify lye calculations using the Soapmaid Lye Calculator before making any batch.
How much cocoa butter should I use in cold process soap?
Use 5–15% of total oils for the best balance of hardness, lather, and conditioning. At 5–10% it adds hardness without affecting lather. Above 15–20% bars can become brittle and lather quality decreases. Most soapmakers find 10–15% the sweet spot for a luxury bar.
Can cocoa butter clog pores?
Cocoa butter has a comedogenicity rating of 4 out of 5 — moderate-to-high likelihood of clogging pores for prone individuals. It is excellent in rinse-off products like soap and in body butters for non-facial use. For leave-on facial products targeting oily or acne-prone skin, consider lower comedogenicity alternatives like jojoba, hemp seed oil, or rosehip oil instead.
Why does my cocoa butter re-solidify in my oil blend?
Cocoa butter has a melting point of 34–38°C — higher than most carrier oils. If your combined oil temperature drops below this while waiting for your lye solution to cool, the cocoa butter can partially re-solidify, creating lumps. Solution: combine your oils while still warm (above 40°C) and monitor the temperature. If it solidifies, gently re-warm the oil blend before combining with lye.
