Eco-Friendly Palm-Free Cold Process Soap Recipe

Create beautiful, effective soap while protecting rainforests and supporting sustainable agriculture. This palm-free recipe replaces traditional palm oil with sustainable alternatives like coconut oil, sunflower oil, and avocado oil. You'll get a hard bar with excellent lather and creamy conditioning properties, all without contributing to deforestation. Perfect for environmentally conscious soap makers who refuse to compromise on quality.

Ingredients

Oils & Butters

• 24 oz (680g) olive oil (extra virgin or pure)
• 14.0 oz (397g) coconut oil
• 10.0 oz (284g) sustainably sourced sunflower oil
• 8.0 oz (227g) avocado oil
• 4.0 oz (113g) shea butter (optional but recommended)

Lye Solution

• 4.9 oz (139g) sodium hydroxide (NaOH)
• 11.5 oz (326g) distilled water

Additives (Optional)

• 0.65 oz (18g) fragrance oil or essential oil blend
• Mica, oxides, or charcoal colorants
• Dried botanicals like calendula, chamomile, or lavender buds

Equipment Needed

• Digital scale (0.1 oz accuracy)
• Two stainless steel pots or bowls
• Heat-safe glass or stainless steel measuring cup
• Stainless steel stirring spoon
• Stick blender (immersion blender)
• Analog or digital thermometer
• Soap mold (silicone or wood-lined)
• Safety goggles and protective gloves
• Parchment paper (for lining molds)
• Soap cutter or serrated knife
• Vinegar (for cleaning)

Instructions

Step 1: Set Up Your Sustainable Soap-Making Station

Prepare your workspace with all equipment within reach. Put on safety goggles and gloves—sodium hydroxide is caustic regardless of its source. Ensure adequate ventilation in your work area. Keep vinegar handy for any accidental spills.

Step 2: Create the Lye Solution

Measure 11.5 oz of distilled water into a heat-safe pot. Very slowly add the 4.9 oz of sodium hydroxide while stirring continuously. The mixture will heat up to 160-180°F as the lye dissolves. Never add water to lye—always add lye to water. Once dissolved, set the pot aside to cool to 100-110°F.

Step 3: Prepare Your Sustainable Oil Blend

In a separate pot, combine all oils and butter:

• 24.0 oz (680g) olive oil
• 14.0 oz (397g) coconut oil
• 10.0 oz (284g) sunflower oil
• 8.0 oz (227g) avocado oil
• 4.0 oz (113g) shea butter

Stir gently to ensure the shea butter is fully incorporated. This blend provides excellent hardness from the coconut and olive oils, conditioning from avocado oil, and moisturizing properties from shea butter.

Step 4: Heat Oils to the Right Temperature

Gently warm the oil blend to 100-110°F. Stir occasionally to ensure even heating. Avoid overheating; if the mixture exceeds 115°F, let it cool before proceeding. Temperature control is crucial for consistent soap quality.

Step 5: Combine Oils and Lye at the Correct Temperature

Once both the lye solution and oils reach 100-110°F, slowly pour the lye solution into the oils while stirring steadily. This combination marks the beginning of saponification. Stir continuously for about one minute to ensure complete incorporation.

Step 6: Blend to Light Trace

Using your stick blender, pulse the mixture for 30 seconds, then stop to stir by hand for one minute. Continue this pulsing and stirring pattern for 8-12 minutes until you reach light trace. The batter should resemble thin pudding or yogurt with visible trails when the blender is lifted out.

Step 7: Add Fragrance and Natural Colors

At light trace, incorporate your 0.65 oz of fragrance oil or essential oil blend. For eco-friendly coloring, consider using natural colorants like activated charcoal (black), spirulina (green), turmeric (golden yellow), or madder root (red). Avoid synthetic colorants to maintain your sustainable philosophy.

Step 8: Pour and Smooth

Pour the soap batter into your prepared mold. Use a spatula to create a smooth, level surface. If desired, sprinkle dried botanicals on top for visual appeal and extra natural benefits.

Step 9: Insulate the Mold

Wrap the soap mold with blankets, towels, or newspaper to insulate it and promote gel phase. This encourages even saponification and creates a more stable final product. Some soapmakers use a cooler or oven set to very low heat.

Step 10: Wait for Saponification

Leave the soap undisturbed for 24-48 hours. The soap will generate its own heat as the saponification reaction occurs. You may notice the soap expanding, changing color, or developing a translucent center—all normal signs of successful soap making.

Step 11: Unmold Your Sustainable Soap

After 24-48 hours, carefully remove the soap from the mold. If it's still soft, wait another 6-12 hours. The soap should feel firm and be easy to handle.

Step 12: Cut Into Uniform Bars

Using a soap cutter or sharp serrated knife, cut the loaf into 24 equal bars. Clean your blade between cuts for the cleanest edges. Work slowly to avoid crumbling or cracking.

Step 13: Air Cure in a Cool Location

Arrange bars on a well-ventilated rack with at least 1 inch between each bar. Cure in a cool, dry place (60-75°F) for 4-6 weeks. Rotate bars occasionally to ensure even drying.

Tips for Success

• Sunflower oil can cause a reddish tint in soap; this is normal and will fade over time
• Avocado oil adds conditioning but can be expensive—start with 8 oz and adjust in future batches
• Shea butter increases hardness and moisturizing properties significantly
• This recipe has a slightly higher water content to accommodate the different oil properties
• Store finished soap in a well-ventilated container away from moisture
• Palm-free soaps often have a slightly longer cure time; be patient for best results

Variations

• Lavender dreamland: Add lavender essential oil, dried lavender buds, and purple mica
• Citrus sunshine: Blend lemon and grapefruit essential oils with yellow oxide colorant
• Unscented pure: Skip fragrance for those with sensitive skin or fragrance sensitivities
• Herbal blend: Add dried chamomile, calendula, and oatmeal for a spa-like bar
