Whether you’re looking to make gifts, personal care products, or even start a small soap business, mastering hot press soap recipes can be your secret weapon to professional-looking, nourishing soaps.
In this blog post, we’ll walk through a detailed hot press soap recipe along with tips, variations, and even nutrition facts for the natural oils used.

Why You’ll Love This Recipe
Hot press soap recipes are beloved by both beginners and seasoned soap makers due to their versatility and quick turnaround. Unlike cold process soaps, which can take weeks to cure, hot press soaps are ready to use in just a few days.
This means less waiting and more enjoying the fruits of your labor.
The recipe we’ll share uses natural oils like olive oil and coconut oil, which are known for their moisturizing and cleansing properties. You can easily customize the scent with essential oils or add exfoliants like oatmeal or coffee grounds for texture.
Additionally, hot press soap’s smooth finish and rich lather make it an excellent choice for sensitive skin, providing gentle cleansing without stripping your skin’s natural oils. Whether you want a simple, calming bar or a colorful, textured masterpiece, this recipe will set you up for success!
Ingredients
- 16 oz Olive Oil – provides moisturizing and conditioning properties
- 8 oz Coconut Oil – adds hardness and bubbly lather
- 4 oz Castor Oil – boosts lather and conditioning
- 4.5 oz Sodium Hydroxide (Lye) – essential for saponification
- 12 oz Distilled Water – used to dissolve the lye safely
- 1 oz Essential Oil Blend (Lavender & Peppermint) – for fragrance
- 1 tbsp Natural Colorants (e.g., turmeric or activated charcoal) – optional for color
- 1 tbsp Ground Oatmeal – optional exfoliant
Equipment
- Safety Gear: Gloves, goggles, and long sleeves for handling lye
- Immersion Blender: for mixing oils and lye solution
- Heat-Safe Containers: stainless steel or heavy-duty plastic for lye solution and oils
- Soap Mold: silicone or wooden lined with freezer paper
- Thermometer: to monitor temperatures of oils and lye
- Scale: for precise measurement of ingredients
- Mixing Spoons and Spatulas
- Plastic or Silicone Gloves for safety
Instructions
- Prepare your workspace: Ensure your area is well-ventilated and all safety gear is worn. Lay out all your ingredients and equipment.
- Measure the lye and water: Carefully weigh 4.5 oz of sodium hydroxide and 12 oz of distilled water separately.
- Mix the lye solution: Slowly add the lye to the water (never the reverse) in a heat-safe container. Stir gently until dissolved. The solution will heat up quickly – set aside to cool to around 110°F.
- Heat the oils: Combine olive oil, coconut oil, and castor oil in a large container. Warm the oils to about 110°F, matching the temperature of the lye solution.
- Combine lye and oils: Slowly pour the cooled lye solution into the oils while blending with an immersion blender. Blend until the mixture reaches a light trace — when the mixture thickens enough to leave a trail on the surface.
- Add fragrance and additives: Stir in your essential oils and optional colorants or exfoliants thoroughly but gently.
- Pour into mold: Immediately pour the soap batter into your prepared mold. Tap the mold gently to remove air bubbles.
- Hot press phase: Cover the mold with plastic wrap, then wrap it with towels to retain heat. Place the mold in a warm area or use a low-temperature oven (around 120°F) to accelerate saponification. Leave it to press for 24-48 hours.
- Unmold and cut: After the pressing phase, remove the soap from the mold and cut it into bars.
- Cure and store: Unlike cold process soaps, hot press soaps need only 2-3 days to cure due to the accelerated process. Store in a cool, dry place before use.
Tips & Variations
“Always add lye to water, never water to lye, to avoid dangerous reactions.” Safety first is the golden rule for soap making!
Experiment with different essential oils depending on your preference. For example, try chamomile for calming effects or grapefruit for a refreshing zing.
If you want a colorful swirl, add natural colorants like spirulina powder (green) or beetroot powder (pink) and layer the soap batter in your mold.
For a luxurious twist, add 1 tablespoon of shea butter or cocoa butter to increase moisturizing effects. Want exfoliation?
Try ground coffee or crushed walnut shells instead of oatmeal. Remember, every additive can change the texture and curing time slightly, so keep notes for your next batch.
