Pomegranate seed oil in soap making
Published by The Soap Brain Team
Values can vary for this oil. The numbers below range quite a bit from one supplier or batch to the next, so we can't pin them to one exact figure. Treat them as a solid starting point — check your supplier's spec sheet, and make a small test batch before a big one.
Pomegranate seed oil is a conditioning soap-making oil rich in linolenic acids (C18:3) (64.7%). A gram of it turns to soap with about 0.135 g of NaOH (lye). It makes a mild, gentle bar and pairs well with a harder, cleansing oil. Most soapers use it at 0–15% of their oils.
Fatty-acid profile
Pomegranate seed oil is a gentle, conditioning oil, mostly unsaturated fatty acids that leave a mild, moisturising bar with a softer, lower lather. It pairs naturally with a harder, more cleansing oil to firm the bar up and add bubbles. Because its polyunsaturated (linoleic/linolenic) share is on the higher side, watch the total across the whole recipe and consider a modest antioxidant to guard against rancidity and DOS.
Pomegranate seed oil is about 8% saturated fat and 91% unsaturated — that unsaturated majority is what makes it conditioning and slower to trace, but softer on its own.
| Fatty acid | Share | What it does in soap |
|---|---|---|
| Linolenic acids (C18:3) | 64.7% | the polyunsaturated C18:3 family — deeply conditioning but the most prone to rancidity; keep the combined polyunsaturated total modest |
| Linoleic acid | 13.5% | a polyunsaturated fatty acid that is very conditioning but oxidises readily — a driver of DOS (dreaded orange spots) at high levels |
| Oleic acid | 12.3% | a monounsaturated fatty acid that makes a gentle, conditioning, moisturising bar with a slick, lower lather and a slower trace |
| Palmitic acid | 5.3% | a saturated fatty acid that builds a hard, long-lasting bar with a stable, creamy lather |
| Stearic acid | 2.8% | a saturated fatty acid that adds hardness and a thick, stable lather; a large share can speed up trace |
Pomegranate seed oil in the bar
Pomegranate seed oil gives a mild, low, slick lather on its own. Blended with a bubbly, cleansing oil it contributes body and mildness while the partner oil supplies the bubbles.
Pomegranate seed oil traces at a fairly typical pace; how fast the whole batch moves will depend mostly on the other oils, your temperatures and any fragrance you add.
In a blend Pomegranate seed oil is the conditioning, skin-feel component and can often make up the bulk of the oils. Add a firmer, more cleansing oil — coconut, palm or a hard butter — to bring hardness and bubbles the finished bar would otherwise miss.
Closest substitutes for Pomegranate seed oil
Out of Pomegranate seed oil? These oils behave most like it in a bar — ranked by how close their hardness, cleansing and conditioning profile and lye (SAP) requirement are. The numbers are predicted properties for a 100% single-oil bar, not a safety guide; always recalculate the lye when you swap an oil.
| Oil | Hardness | Cleansing | Conditioning | SAP (NaOH) |
|---|---|---|---|---|
| Pomegranate seed oil (this oil) | 8 | 0 | 91 | 0.135 |
| Sunflower oil, high-oleic | 9 | 0 | 91 | 0.135 |
| Camellia / tea seed oil | 9 | 0 | 90 | 0.136 |
| Kukui nut oil | 6 | 0 | 90 | 0.135 |
| Apricot kernel oil | 5 | 0 | 90 | 0.135 |
Using Pomegranate seed oil in a recipe
One gram of Pomegranate seed oil needs about 0.135 g of NaOH (sodium hydroxide) to turn fully to soap, within a documented range of 0.123–0.163 g/g across sources. The calculator below uses this value; always confirm the lye weight before you mix.
Its iodine value is about 150 — a higher value, pointing to a softer, more conditioning bar that is more prone to rancidity (DOS). Iodine value is only a rough guide, not a hard rule, but it gives you a feel for how a bar built around this oil will wear.
Most soapers use Pomegranate seed oil at roughly 0–15% of their oils.
Maker's note: Thick, rich feel; very oxidation-prone, so keep it refrigerated and use it in small amounts. Its numbers vary a lot by cultivar and how it was pressed.
Calculate lye for Pomegranate seed oil
The calculator below is pre-loaded with Pomegranate seed oil. Enter your weights, add other oils, and it works out the exact NaOH (lye) weight, water and quality numbers. Always weigh lye, oils and water — never measure by volume, wear gloves and eye protection, and add lye to water (never the reverse).

Pomegranate seed oil soap FAQ
- Can you make soap with 100% Pomegranate seed oil?
- It is not recommended. Pomegranate seed oil shows its best in a blend, usually up to about 15% of the oils. On its own the bar would be unbalanced — too soft or low-lathering for everyday use.
- What superfat should I use with Pomegranate seed oil?
- A 5% superfat is a safe, common starting point for recipes using Pomegranate seed oil; adjust to taste once you know how the finished bar feels. Never drop to 0% or below without a deliberate reason — the calculator will ask you to confirm it.
- Does Pomegranate seed oil speed up or slow down trace?
- Pomegranate seed oil traces at a fairly typical pace; how fast the whole batch moves will depend mostly on the other oils, your temperatures and any fragrance you add.
