Ingredients

Base

• 2.0 lbs (908g) white melt and pour soap base

Charcoal and Additives

• 0.75 tsp (4ml) activated charcoal powder
• 1.0 oz (28g) fractionated coconut oil (for charcoal suspension)
• 1.5 tsp (8ml) tea tree essential oil
• 0.5 tsp (2ml) eucalyptus essential oil
• 0.5 tsp (2ml) thyme essential oil

Color and Optional Additives

• Small amount of activated charcoal provides natural black color
• 1 tbsp (15g) ground tea tree leaves (optional, for texture and visual interest)

Equipment Needed

• Microwave-safe glass bowl or double boiler
• Thermometer
• Digital scale
• Rubber spatula
• Measuring spoons
• Small glass bowl (for charcoal prep)
• Fine mesh strainer
• Silicone molds (14-18 cavity)
• Spray bottle with isopropyl alcohol
• Cooling surface
• Small whisk

Instructions

Step 1: Prepare Charcoal Suspension

Combine activated charcoal powder (0.75 tsp) with fractionated coconut oil (1 oz) in a small glass bowl. Mix thoroughly with a small whisk, ensuring no charcoal clumps remain. The oil prevents charcoal from settling to the bottom of soap bars, ensuring even color distribution. Set aside at room temperature.

Step 2: Prepare Essential Oil Blend

In a separate small container, measure out tea tree essential oil (1.5 tsp), eucalyptus essential oil (0.5 tsp), and thyme essential oil (0.5 tsp). Combine these together gently. This pre-blended mixture ensures even distribution of the complex aromatic profile throughout the soap. The combination of these oils creates synergistic antibacterial action.

Step 3: Optional Tea Tree Leaves Prep

If using ground tea tree leaves for texture, place 1 tbsp in a small bowl and set aside. These will be added at the final stages to create visual appeal and additional antimicrobial benefit.

Step 4: Set Up Workspace

Arrange all equipment and ingredients within reach for efficient workflow. Place silicone molds on a clean, level, stable surface at room temperature (68-72°F). Ensure excellent ventilation when working with tea tree oil, as it produces strong, concentrated vapors. Open windows and use fans if necessary.

Step 5: Cut and Weigh Soap Base

Remove melt and pour soap base from packaging and cut into 1-inch cubes. Using your digital scale, measure exactly 2 lbs of cubed soap. Store excess for future batches.

Step 6: Melt Soap Base

Place cubed soap in a microwave-safe glass bowl. Heat in 30-second intervals, stirring between each interval, until completely melted. Alternatively, use a double boiler with simmering water beneath. Target temperature is 170-175°F. Avoid exceeding 180°F, which can cause volatile oil components to evaporate.

Step 7: Verify Temperature

Using your thermometer, confirm the soap has reached 170-175°F and is completely melted with no lumps. The soap should be clear and smooth. If overheated, allow 1-2 minutes cooling time.

Step 8: Add Charcoal Suspension

Slowly pour the charcoal-oil mixture into the melted soap while stirring constantly. Add gradually over 1-2 minutes to prevent sudden clumping or color streaking. Continue stirring vigorously for 3-4 minutes until the charcoal is evenly dispersed throughout. The entire mixture should have a uniform deep black color.

Step 9: Incorporate Essential Oil Blend

Pour the prepared essential oil blend into the soap and stir very thoroughly for 3-4 minutes. Tea tree oil is potent and must be completely dispersed to avoid creating "hot spots" of overwhelming scent or skin irritation. Every bar should have consistent essential oil distribution.

Step 10: Add Optional Tea Tree Leaves

If using ground tea tree leaves, add them now and fold gently into the mixture. Stir for 1-2 minutes to distribute evenly. These leaves add visual texture and enhance the antibacterial properties.

Step 11: Cool Before Molding

Remove from heat and allow to cool for 2-3 minutes. The mixture should remain pourable but not piping hot. This cooling period prevents the charcoal from settling during the molding process.

Step 12: Pour into Molds

Carefully pour the tea tree charcoal soap into silicone molds, filling each cavity 3/4 to full. Work at a steady, consistent pace. If the mixture begins to thicken during pouring, reheat briefly (10-15 seconds) in the microwave.

Step 13: Remove Air Bubbles

Inspect the molded soap for surface air bubbles. Lightly spray with isopropyl alcohol and gently tap the molds. This creates smooth, professional-looking bars without visible imperfections.

Step 14: Allow Initial Set

Let the molded soap cool at room temperature for 2-3 hours without disturbance. The charcoal will settle completely, and the bars will firm up considerably.

Step 15: Complete Cooling

After initial setting, allow additional cooling time or place in a cool location to accelerate hardening. The bars are ready for demolding when you can insert a fingernail without leaving an impression.

Step 16: Demold and Inspect

Gently flex the silicone molds to release the bars. If resistance occurs, place in the refrigerator for 15-20 minutes to firm up further, then try again. Inspect bars for any cracks or imperfections.

Step 17: Air Cure

Allow bars to air dry on a clean surface for 24-48 hours before use or packaging. During this time, the soap will harden further and the charcoal color may deepen slightly. This curing period allows essential oils to integrate fully with the soap base.

Step 18: Storage

Store finished bars in a cool, dry location away from direct sunlight. Keep in an airtight container or sealed bag if possible, as this helps preserve the potency of the essential oils.

Tips for Success

• Tea Tree Oil Strength: Tea tree oil is very concentrated. Using the proper amount is crucial to avoid creating a product that's too strong for sensitive skin. The 1.5 tsp amount is carefully calculated for a 2 lb batch.
• Ventilation is Essential: Adequate ventilation is non-negotiable when working with tea tree oil. The vapors are strong and can cause respiratory irritation if inhaled heavily.
• Even Charcoal Distribution: Vigorous, consistent stirring ensures charcoal doesn't settle unevenly. Stir in firm, circular motions to keep particles suspended throughout molding.
• Test Before Giving as Gifts: If making for others, test the soap on a small area first to ensure it's not too strong for their skin type.
• Proper Curing Time: Allow at least 24 hours of curing before use. This allows the essential oils to set into the soap properly and reduces any potential for skin irritation.

Variations

• Tea Tree and Lavender: Replace half the eucalyptus with lavender essential oil (0.25 oz) for a gentler, more soothing acne-fighting bar.
• Tea Tree and Rosemary: Combine 0.5 oz rosemary essential oil with tea tree for enhanced antibacterial action and stimulating properties.
• Tea Tree with Ground Pumice: Add 1-2 tbsp finely ground pumice for gentle exfoliation along with antibacterial action.
