Safflower oil, high oleic: SAP value and fatty acids
Safflower oil, high oleic has a saponification value of 190 mg KOH/g. One gram needs 0.135 g of sodium hydroxide (NaOH) for bar soap or 0.190 g of potassium hydroxide (KOH) for liquid soap to turn fully into soap, before any superfat.
Key numbers
- SAP, NaOH
- 0.135448 g per g oil
- SAP, KOH
- 0.19 g per g oil
- Saponification value
- 190 mg KOH/g
- Iodine value
- 90
- INS
- 100
- INCI name
- Carthamus Tinctorius Seed Oil
Example: 100 g of Safflower oil, high oleic with no superfat needs 13.5 g of 100% NaOH, or 19.0 g of 100% KOH. A 5% superfat uses 5% less.
In soap
Its main fatty acids in our cited profile are oleic (76.9%) and linoleic (14.5%). The eight fatty acids used in soap-quality scores make up 99% of the profile.
On its own it scores 7 for hardness, 0 for cleansing and 92 for conditioning, with a saturated : unsaturated split of 7 : 92.
High-oleic safflower (at least 70% oleic acid per Codex) behaves much like olive oil in soap and keeps better than standard safflower.
Fatty-acid profile
| Fatty acid | % of fatty acids | Counts toward |
|---|---|---|
| lauric | 0.1% | hardness, cleansing, bubbly lather |
| myristic | 0.1% | hardness, cleansing, bubbly lather |
| palmitic | 4.8% | hardness, creamy lather |
| stearic | 2% | hardness, creamy lather |
| ricinoleic | 0% | conditioning, bubbly and creamy lather |
| oleic | 76.9% | conditioning |
| linoleic | 14.5% | conditioning |
| linolenic | 0.6% | conditioning |
Basis: Codex CXS 210 Table 1 (safflowerseed oil, high oleic acid) midpoints; Codex range midpoints; 'ND' = 0, 'ND–x' or '<x' = x/2.
Soap-quality scores (this oil alone)
| Hardness | 7 |
|---|---|
| Cleansing | 0 |
| Conditioning | 92 |
| Bubbly lather | 0 |
| Creamy lather | 7 |
| Iodine | 90 |
| INS | 100 |
Each score adds up certain fatty acids, the way Soap Ledger scores a whole recipe. They are for comparing recipes; they don't predict how a bar will feel, and they say nothing about safety or skin.

NaOH and KOH values are converted from mg KOH/g with the molar masses 39.997 and 56.106 and rounded to 6 decimals, exactly as in the Soap Ledger app. Real oils vary by origin, grade and lot: check your supplier's certificate of analysis. Verify every weight before you make this, and follow lye safety. Not a safety or compliance certification.
