5 Steps to Make a 100% Sunflower Oil Soap Recipe
First, measure 750 g sunflower oil, 152.78 g of 90% potassium hydroxide, and 305.55 g liquid for a 50% lye solution, prepping all tools and safety gear.
Slowly mix the KOH into the liquid and cool both to about 116°F.
Pour the lye solution into the oil and blend gently to light trace, then add fragrance and pour into your mold.
Wrap and cure your soap for 4–6 weeks for the best results.

Key Takeaways
- Measure 750 g high-oleic sunflower oil and prepare a 50% potassium hydroxide (KOH) lye solution with 305.55 g liquid.
- Slowly dissolve 152.78 g KOH in the liquid. Make sure to cool both the lye and oil to around 116°F (46.9°C) before combining them.
- Combine the lye solution with the oil. Blend with a stick blender in bursts until you reach a light trace.
- Add fragrance at light trace and stir gently. Then, pour the soap batter into your prepared mold.
- Insulate the mold for 24 hours. After that, unmold and cure the soap bars for 4–6 weeks before using them.
Measure and Ready Your Ingredients and Equipment
Begin by carefully weighing 750 grams of high-oleic sunflower oil in a heat-safe mixing vessel. Next, measure 152.78 grams of potassium hydroxide (KOH) at 90% purity on a separate scale, using a dedicated lye container.
Start by weighing 750 grams of sunflower oil and 152.78 grams of 90% pure potassium hydroxide separately.
Always wear gloves, goggles, and a mask while handling lye for safety. Prepare 305.55 grams of liquid—either water, glycerin, or a mix for a 50% KOH solution—in a heat-resistant jug, chilled or at room temperature as needed.
Arrange your equipment: stick blender, thermometer, spatulas, stainless steel or heavy-duty plastic bowls, and a soap mold. Have towels or insulating blankets ready for later.
Double-check all weights and safety gear, label containers clearly, and keep children and pets away from your workspace before moving forward. It’s best to be extra cautious here!
Prepare and Cool Your Lye Solution and Sunflower Oil
When you add the potassium hydroxide (KOH) to your measured liquid, do so slowly and stir continuously to help it dissolve completely. Be prepared for the mixture to heat up rapidly.
Weigh 152.78 g of 90% KOH and 305.55 g of water or a water/glycerin mix separately for an exact 33.33% lye concentration. Make sure to use a heatproof, chemical-resistant container for mixing.
After dissolving, let the lye solution cool to about 116°F (46.9°C). You can use a cool water bath if needed, just keep an eye on the temperature with a thermometer.
Meanwhile, weigh 750 g of high-oleic sunflower oil. Warm or cool it so it’s about the same temperature as the lye solution.
Once both reach around 116°F, you’re all set to move forward with your soap-making process. Easy, right?
Combine and Blend to Reach Trace
Slowly pour the cooled lye solution into the warmed sunflower oil while stirring manually to combine them thoroughly. Use a stick blender in short bursts, alternating with gentle stirring to prevent overheating.
Pour the cooled lye into warmed sunflower oil slowly, blending gently to avoid overheating and ensure thorough mixing.
Since sunflower oil soap emulsifies slower than mixed oils, expect trace to take longer. Watch for a creamy, silky consistency where a dribbled ribbon stays briefly on the surface—that’s light trace.
Keep these points in mind:
- Blend carefully to avoid premature thickening or overheating.
- Aim for a light to medium trace depending on your molding preference.
- Scrape the bowl and stop blending promptly once you reach trace to prevent the batter from seizing.
This makes certain your soap batter is ready for the next step without rushing. Just take it slow and steady!
Add Fragrance at Trace; Pour Soap Into Mold
Although the soap batter has just started to thicken, you should add your fragrance at light trace to guarantee it disperses evenly without pushing the mixture to full trace too quickly. Use the manufacturer’s recommended rate—typically 0.5–1.5% of your batch weight.
For sticky or viscous fragrance oils, pre-dilute them in a small amount of carrier oil or room-temperature distilled water. Stir gently into the batter for 20–30 seconds to avoid over-mixing.
Pour the fragranced soap batter immediately into your prepared mold while it’s still pourable to prevent seizing or uneven texture. Once poured, tap the mold gently to release trapped air bubbles and smooth the surface as needed.
This makes certain your soap sets evenly with a consistent scent throughout.
Insulate and Cure Your Sunflower Soap
Once you’ve poured your fragranced sunflower soap batter into molds, wrap them snugly with towels or blankets to trap heat and encourage the gel phase. Keep the molds in a warm, draft-free spot for about 24 hours to promote even saponification and avoid cracking or soda ash.
Wrap your soap molds warmly to encourage gel phase and prevent cracking during saponification.
When you’re ready, unmold the bars and cure them on a ventilated rack for 4–6 weeks. This helps excess water evaporate and allows the soap to harden nicely.
To make certain of the best results:
- Rotate or flip the bars occasionally for even drying and shape.
- Store cured soap in a cool, dry place away from sunlight and humidity.
- Allow curing to fully develop optimal pH and hardness before use.
Proper insulation and curing guarantee a long-lasting, high-quality sunflower soap. Just a little patience goes a long way!
Frequently Asked Questions
How Much Essential Oil Do You Add to Soap?
You add about 0.5–1.0% essential oil by weight to your soap batch. For a 1200g batch, that’s roughly 6–12g.
Always check each oil’s safety limits and add at light trace for best scent. It helps to get the fragrance just right without overpowering.
How Do They Make Organic Sunflower Oil?
They grow sunflower seeds without chemicals and use natural fertilizers. Then, they harvest the seeds carefully to keep them in great condition.
After that, the seeds are cold-pressed or expeller-pressed to extract the oil. The oil gets filtered next, and they make sure it meets organic standards before labeling it as organic sunflower oil.
What Is the Best Fragrance Oil for Cold Process Soap?
You’ll want a skin-safe fragrance oil with a high flash point and proven cold process stability—lavender or rosemary often work well.
It’s a good idea to test small batches first, because some scents can unexpectedly seize or discolor your soap. Better to be safe than sorry!
What Ingredient to Avoid in Bar Soap?
You should avoid liquid detergents, synthetic surfactants, and excessive glycerin. These ingredients can make your soap bars soft and sticky, which is not ideal.
Also, steer clear of fresh food additives and raw honey above 3%. They can cause your soap to spoil or discolor over time.
Untested fragrance oils are another no-go. They might irritate your skin and ruin the soap’s quality. So, it’s best to be cautious with what you add!
