oil

Apple Seed Oil

A specialty liquid oil that can contribute a soft, mild-feeling quality in a blended bar. As a liquid oil, it does not provide the firming role of solid fats.

Working with it
Moderate

Check that the product is neat apple seed oil, not an extract or an infused carrier oil.

0.138 NaOH SAP Source linked
oil

Apricot Kernel Oil

A soft liquid oil that can add a mild, smooth feel to a blended cold-process bar. It is not a hard-oil or big-bubble substitute on its own.

Working with it
Easy

It blends like other liquid oils; confirm the product is apricot kernel oil before recalculating a substitution.

0.139 NaOH SAP Source linked
oil

Argan Oil

A liquid specialty oil suited to a supporting role in a blend; it contributes softness rather than the firmness or large bubbles associated with some solid fats.

Working with it
Moderate

Match the supplier's exact argan oil and keep its own SAP reference when changing an existing recipe.

0.136 NaOH SAP Source linked
oil

Avocado Oil

A soft liquid oil used in blended bars for a mild, conditioned feel. It generally traces more slowly than hard fats and will not firm a recipe by itself.

Working with it
Easy

A familiar blending oil; check the supplier's grade and recalculate lye whenever the oil changes.

0.133 NaOH SAP Source linked
oil

Babassu Oil

Its lauric-rich profile can contribute firm bars and abundant bubbles, with cleansing character similar to—but not identical to—coconut oil.

Working with it
Moderate

Melt the solid oil fully and use its own SAP reference; do not substitute coconut-oil values.

0.175 NaOH SAP Source linked
oil

Borage Oil

A delicate, unsaturated liquid oil for specialty blends. It adds softness rather than bar structure; a formula's freshness and oxidation resistance matter.

Working with it
Challenging

Buy a fresh, well-stored product, identify it precisely, and avoid relying on it as the bar's main hardening oil.

0.135 NaOH SAP Source linked
oil

Canola Oil (high oleic)

This high-oleic liquid oil can support a mild-feeling, slower-moving batter. Like other liquid oils, it contributes less firmness than solid fats.

Working with it
Moderate

Verify the high-oleic grade; ordinary and high-oleic canola have different fatty-acid profiles.

0.133 NaOH SAP Source linked
oil

Carrot Seed Oil (cold-pressed)

A specialty seed oil that behaves as a liquid blend ingredient; do not assume it will add a lasting carrot color or scent to finished soap.

Working with it
Challenging

Check the label carefully: this entry is cold-pressed fatty seed oil, not carrot-seed essential oil or an infusion.

0.103 NaOH SAP Source linked
oil

Castor Oil

Castor oil can support a stable, creamy lather in a balanced recipe. Its thick, sticky batter can become difficult to pour when castor dominates the oil blend.

Working with it
Moderate

Measure carefully: castor oil is unusually viscous. A single-oil castor batch behaves very differently from a normal blend.

0.128 NaOH SAP Source linked
butter

Cocoa Butter

This room-temperature solid butter can add firmness and a creamy lather to a blended bar; it does not create the fluffy bubbles of lauric-rich oils.

Working with it
Easy

Melt fully and combine evenly with the liquid oils before making the lye calculation.

0.138 NaOH SAP Source linked
oil

Coconut Oil (76°)

Coconut oil can add firmness, large fluffy bubbles, and a more cleansing feel. A formula's overall balance matters; the ingredient alone does not predict the finished bar.

Working with it
Easy

Melt and mix evenly; use the 76-degree product's own SAP, not values for fractionated coconut oil.

0.183 NaOH SAP Source linked
butter

Cupuacu Butter

A firm plant butter that can add structure and a creamy quality to a blended cold-process bar.

Working with it
Moderate

Melt completely and identify the supplier's exact butter grade; cupuaçu is not interchangeable with cocoa or shea butter.

0.137 NaOH SAP Source linked
oil

Working with it
Challenging

Check freshness and storage history, and verify the exact supplier specification before using its reference SAP.

0.135 NaOH SAP Source linked
oil

Fractionated Coconut Oil

This liquid caprylic/capric oil does not have the same lauric-rich profile as regular coconut oil, so it will not reproduce the same lather and cleansing role.

Working with it
Challenging

Confirm the product is caprylic/capric triglycerides. Never swap in 76-degree coconut oil's SAP value.

0.232 NaOH SAP Source linked
oil

Grapeseed Oil

oil

Hemp Seed Oil

A soft, unsaturated liquid oil for blended recipes; it contributes less firmness than room-temperature solid fats.

Working with it
Moderate

Protect this delicate oil from heat, light, and air, and distinguish plain seed oil from blended hemp products.

0.138 NaOH SAP Source linked
oil

Jojoba Oil (golden)

Jojoba is a liquid wax ester, not a typical triglyceride oil. Its unusual composition means it does not behave like common soapmaking oils.

Working with it
Challenging

Use only a jojoba-specific SAP reference and test cautiously; its very low saponification value and unusual behavior make substitutions tricky.

0.066 NaOH SAP Source linked
butter

Kokum Butter

A very firm plant butter that can contribute structure and a harder feel to a blended bar.

Working with it
Moderate

Break up and melt fully before blending; confirm the exact butter because its reference SAP differs from other butters.

0.135 NaOH SAP Source linked
oil

Kukui Nut Oil

A soft liquid nut oil for blended recipes. It contributes less bar firmness than solid fats, so the full formula determines hardness and cure behavior.

Working with it
Moderate

Check that the oil is fresh and confirm its botanical/product identity in the supplier specification.

0.135 NaOH SAP Source linked
butter

Mango Butter

A room-temperature solid butter that can increase firmness and contribute a creamy lather in a balanced blend.

Working with it
Easy

Melt completely and weigh accurately; mango butter's SAP is not the same as shea or cocoa butter.

0.136 NaOH SAP Source linked
oil

Marula Oil

A liquid specialty oil for balanced blends. Its liquid-oil character adds softness rather than the firmness or large bubbles supplied by hard fats.

Working with it
Moderate

Match the supplier's exact marula oil and recalculate lye if replacing another ingredient.

0.137 NaOH SAP Source linked
oil

Moringa Seed Oil

A high-oleic liquid oil that can suit a mild-feeling blend. It remains a soft oil, so the complete formula provides the bar's structure.

Working with it
Moderate

Choose the pressed seed oil, not a botanical extract, and verify the product's stated grade.

0.137 NaOH SAP Source linked
butter

Murumuru Butter

A hard, lauric-rich butter that can contribute a firm bar and abundant lather. Its SAP is notably different from many common butters.

Working with it
Challenging

Melt thoroughly and recheck the exact supplier SAP; do not substitute a generic butter value.

0.196 NaOH SAP Source linked
oil

Neem Oil

A liquid specialty oil with a strong, distinctive odor that may remain noticeable in finished soap. It contributes softness, not bar structure.

Working with it
Moderate

Plan for its strong natural scent and verify that the product is neem seed oil rather than an extract or blend.

0.138 NaOH SAP Source linked
oil

Oat Oil

A soft liquid oil that can add a mild-feeling quality to a blend; it does not provide the firming effect of solid fats.

Working with it
Moderate

This entry is oat-derived oil, not colloidal oatmeal, oat extract, or oat protein; confirm the supplier's exact product.

0.135 NaOH SAP Source linked
oil

Olive Oil

Olive oil contributes a mild-feeling bar and a small, dense lather. A high-olive recipe can trace slowly and may need extra time to harden and cure.

Working with it
Easy

A familiar liquid oil, but patience may be needed before unmolding and during the cure of olive-heavy recipes.

0.135 NaOH SAP Source linked
oil

Olive Oil (pomace)

Pomace olive oil contributes a mild-feeling bar with dense lather, much like other olive-oil soaps. It can behave differently from other grades during mixing.

Working with it
Moderate

Identify the pomace grade and follow a recipe designed for it; do not assume every olive oil has identical handling or SAP.

0.134 NaOH SAP Source linked
oil

Palm Kernel Flakes (hydrogenated)

These hard flakes can add firmness and large bubbles, like other lauric-rich fats. They are a distinct grade and do not share every palm-oil property.

Working with it
Challenging

Melt fully and confirm hydrogenation and product identity; regular palm kernel oil and palm fruit oil are different ingredients.

0.176 NaOH SAP Source linked
oil

Palm Kernel Oil

Palm kernel oil can contribute firmness, large bubbles, and a more cleansing feel because of its lauric-rich profile.

Working with it
Moderate

Melt and stir thoroughly; distinguish kernel oil from palm fruit oil and hydrogenated palm-kernel flakes.

0.176 NaOH SAP Source linked
oil

Palm Oil

Palm fruit oil can add firmness and a stable, creamy lather to a blended bar. It is different from palm kernel oil, which has a more bubbly profile.

Working with it
Easy

If the container separates, mix it evenly before weighing; verify that the product is palm fruit oil.

0.142 NaOH SAP Source linked
oil
