Charcoal, with its deep black hue and potent cleansing properties, has become a popular ingredient in the world of soapmaking. But not all charcoal is created equal. Understanding the different types of charcoal and their specific characteristics is crucial for crafting soap that not only looks stunning but also delivers the desired benefits. This article delves into the world of charcoal for soapmaking, exploring the various options, their properties, and how to choose the right one for your next batch.
Understanding Charcoal: More Than Just Black Dust
Before diving into the specific types, it’s essential to understand what charcoal is and why it’s used in soap. Charcoal is a carbon-rich material produced by heating organic matter in the absence of oxygen, a process known as pyrolysis. This process removes water, volatile compounds, and other impurities, leaving behind a substance that is primarily carbon.
The key reason charcoal is incorporated into soap is its exceptional absorptive properties. Its porous structure allows it to bind to dirt, oil, and other impurities on the skin, effectively drawing them out. This makes charcoal soap particularly beneficial for individuals with oily or acne-prone skin. Beyond its cleansing abilities, charcoal also imparts a beautiful, natural black color to soap, adding to its aesthetic appeal.
The Two Main Types of Charcoal for Soapmaking
When it comes to soapmaking, two main types of charcoal stand out: activated charcoal and cosmetic-grade charcoal. While both are derived from similar sources, their processing and intended use differ significantly.
Activated Charcoal: The Cleansing Powerhouse
Activated charcoal is charcoal that has been treated to increase its surface area and absorptive capacity. This activation process typically involves heating the charcoal with a gas or chemical agent, creating millions of tiny pores within its structure. This dramatically increases its surface area, making it exceptionally effective at absorbing impurities.
The source of activated charcoal can vary, including wood, coconut shells, bamboo, and peat. Each source contributes slightly different properties to the final product, influencing its texture, particle size, and overall performance in soap.
Benefits of Activated Charcoal in Soap
- Deep Cleansing: Its superior absorptive properties draw out dirt, oil, and toxins from the skin.
- Exfoliation: Fine particles can provide gentle exfoliation, removing dead skin cells and leaving skin smoother.
- Acne Treatment: Helps to unclog pores and reduce inflammation associated with acne.
- Detoxification: Binds to pollutants and toxins on the skin’s surface.
Choosing the Right Activated Charcoal
When selecting activated charcoal for soapmaking, consider the following:
- Source: Coconut shell activated charcoal is a popular choice due to its fine texture and high absorptive capacity. Wood-based activated charcoal is another option, but its particle size may be slightly larger.
- Particle Size: Opt for a fine powder to ensure even distribution throughout the soap and to avoid a gritty texture.
- Purity: Ensure the activated charcoal is food grade or cosmetic grade to avoid any harmful contaminants.
- Activation Method: Steam-activated charcoal is generally preferred over chemical-activated charcoal, as it is considered more natural.
Cosmetic-Grade Charcoal: A Gentle Alternative
Cosmetic-grade charcoal is a more general term that refers to charcoal specifically processed and purified for use in cosmetic products, including soap. While it may not always undergo the same activation process as activated charcoal, it is still carefully screened for impurities and contaminants.
Cosmetic-grade charcoal can be derived from various sources, similar to activated charcoal. The key difference lies in the level of processing and the intended application. It is often chosen for its gentler properties and suitability for sensitive skin.
Benefits of Cosmetic-Grade Charcoal in Soap
- Gentle Cleansing: Provides effective cleansing without being overly drying or irritating.
- Coloring Agent: Imparts a deep, natural black color to soap.
- Suitable for Sensitive Skin: Often less abrasive than activated charcoal, making it a good choice for those with sensitive skin.
- Improved Lather: Some cosmetic-grade charcoals can contribute to a richer, more luxurious lather.
Considerations for Cosmetic-Grade Charcoal
- Purity: Look for charcoal specifically labeled as cosmetic grade to ensure it meets safety standards.
- Particle Size: Choose a fine powder for smooth incorporation into soap.
- Source: Consider the source of the charcoal based on your personal preferences and ethical considerations. Bamboo charcoal is often a sustainable choice.

Bamboo Charcoal
Bamboo charcoal is derived from bamboo plants and is often touted for its sustainable sourcing. It can be found in both activated and cosmetic-grade forms. Bamboo charcoal is known for its fine texture and excellent absorption properties.
Bincho-tan Charcoal
Bincho-tan charcoal, originating from Japan, is a high-quality charcoal produced through a unique firing process. It is known for its hardness, density, and long burning time. While primarily used for grilling, finely ground Bincho-tan charcoal can be used in soapmaking for its cleansing and detoxifying properties.
How to Incorporate Charcoal into Soap
Adding charcoal to soap is a relatively straightforward process, but a few key tips will ensure the best results.
Dosage
Start with a small amount of charcoal, typically 1-2% of the total soap recipe weight. You can gradually increase the amount in subsequent batches to achieve the desired color and cleansing effect. Adding too much charcoal can result in a gritty texture or overly drying soap.
Preparation
Before adding charcoal to your soap batter, it’s essential to disperse it properly. This prevents clumping and ensures even distribution throughout the soap. Mix the charcoal with a small amount of oil from your recipe or distilled water to form a slurry.
Mixing
Add the charcoal slurry to your soap batter at trace, just before pouring it into the mold. Mix thoroughly to ensure the charcoal is evenly distributed. Be careful not to overmix, as this can lead to a grainy texture.
Safety Precautions
Always wear a mask and gloves when working with charcoal powder, as it can be irritating to the respiratory system and skin. Work in a well-ventilated area.
Troubleshooting Charcoal Soap
Even with careful planning, issues can sometimes arise when making charcoal soap. Here are some common problems and how to address them:
- Gritty Texture: This is usually caused by using too much charcoal or not dispersing it properly. Reduce the amount of charcoal and ensure thorough dispersion in future batches.
- Uneven Color: This can occur if the charcoal is not mixed evenly throughout the soap batter. Mix more thoroughly in subsequent batches.
- Drying Soap: Charcoal can be drying to the skin, especially if used in high concentrations. Reduce the amount of charcoal or add moisturizing ingredients like shea butter or olive oil to your recipe.
- Color Bleeding: In melt and pour soap, charcoal can sometimes bleed into other colors. To prevent this, use a small amount of charcoal and avoid swirling it excessively.
The Bottom Line: Choosing the Right Charcoal for Your Soap
Selecting the right type of charcoal for soapmaking depends on your specific goals and the needs of your target audience. Activated charcoal is an excellent choice for deep cleansing and addressing oily or acne-prone skin. Cosmetic-grade charcoal is a gentler alternative suitable for sensitive skin and general use.

What is the best type of charcoal to use in soap making?
The best type of charcoal for soap making is activated charcoal powder. Activated charcoal has been processed to increase its surface area, making it incredibly porous. This enhanced porosity allows it to effectively absorb impurities and toxins, providing excellent cleansing and detoxifying properties to your soap. Look for food-grade or cosmetic-grade activated charcoal to ensure its safety for topical use.
Avoid using charcoal briquettes or other types of charcoal intended for grilling. These charcoals often contain additives and binders that are not safe for skin and could negatively impact the quality of your soap. Additionally, they lack the fine texture and high surface area of activated charcoal, making them less effective at providing the desired cleansing benefits.
Why is activated charcoal used in soap making?
Activated charcoal is primarily used in soap making for its exceptional cleansing and detoxifying properties. Its porous structure binds to dirt, oil, and other impurities on the skin, effectively drawing them out of pores. This results in a deep clean that can help alleviate acne, blackheads, and other skin conditions caused by clogged pores.
Beyond its cleansing abilities, activated charcoal can also contribute to the visual appeal of soap. It imparts a deep, rich black color, which can be used to create striking designs and patterns. This natural colorant eliminates the need for artificial dyes, making your soap more appealing to those seeking natural and eco-friendly products.
How much activated charcoal should I add to my soap recipe?
The amount of activated charcoal you add to your soap recipe depends on the desired color intensity and the size of your batch. A general guideline is to start with 1 teaspoon of activated charcoal powder per pound of soap base. This will typically produce a light to medium gray color.
For a darker black hue, you can increase the amount of charcoal, but be cautious not to add too much. Excessive charcoal can make the soap gritty or drying. Experimenting with small batches is recommended to determine the ideal amount for your specific recipe and desired outcome.
Can activated charcoal soap dry out the skin?
Activated charcoal, when used in moderation, should not inherently dry out the skin. However, like any soap, overusing it or using a soap with an unbalanced formula can lead to dryness. Activated charcoal can absorb oils, so it’s crucial to formulate your soap with moisturizing ingredients like olive oil, shea butter, or coconut oil to counteract any potential drying effects.
To minimize the risk of dryness, consider adding a higher percentage of superfatting oils to your recipe. Superfatting means including extra oils that are not fully saponified during the soap making process, leaving them available to moisturize the skin. Also, advise users to avoid using charcoal soap multiple times a day, especially if they have naturally dry skin.
How do I prepare activated charcoal for use in soap making?
Before adding activated charcoal to your soap batter, it’s essential to disperse it properly to prevent clumping and ensure even distribution. The best way to do this is to pre-mix the activated charcoal with a small amount of oil from your soap recipe.
Gradually add the activated charcoal powder to the oil, stirring continuously until a smooth paste forms. This slurry can then be easily incorporated into your soap batter during the trace stage, ensuring a consistent color and even distribution of the charcoal’s benefits throughout the soap.
Is there a difference between wood-based and coconut-based activated charcoal for soap?
Both wood-based and coconut-based activated charcoal can be used effectively in soap making, but there are subtle differences to consider. Coconut-based activated charcoal is often considered to have a finer particle size and a slightly higher surface area than wood-based charcoal. This can result in a smoother texture and potentially better absorption capabilities in your soap.
The choice between wood-based and coconut-based activated charcoal often comes down to personal preference and availability. Both types offer excellent cleansing properties and can create beautiful black soap. Consider the sourcing and sustainability of each type when making your selection.
Can activated charcoal soap help with acne?
Yes, activated charcoal soap can be beneficial for managing acne. Its ability to draw out impurities and excess oil from pores can help unclog pores and reduce breakouts. By absorbing toxins and bacteria, activated charcoal can help prevent the formation of new acne lesions and promote clearer skin.
However, it’s important to remember that activated charcoal soap is not a cure-all for acne. It works best as part of a comprehensive skincare routine that includes cleansing, moisturizing, and potentially other acne-fighting treatments as recommended by a dermatologist. The effectiveness of activated charcoal soap can vary from person to person, and individual results may differ.
