It’s important to note that specific values may vary based on factors such as the source of the hazelnuts, the extraction method, and other processing considerations. If precise information is needed for a specific product or application, it’s advisable to refer to the supplier’s specifications or consult reliable sources for accurate data.
FATTY ACIDS COMPOSITION (Fatty Acid Fraction):
| Lipid | Fatty Acid | Range | Typical | Soap Property |
|---|---|---|---|---|
| C18:2 | Linoleic | 7.0 - 30.0 % | 21.0 % | Conditioning, Moisturizing, Silky Lather |
| C18:1 | Oleic | 62.0 - 86.0 % | 70.0 % | Conditioning, Moisturizing |
| C16:0 | Palmitic | 4.0 - 9.0 % | 5.5 % | Hardness, Stable Creamy Lather |

IODINE VALUE: 80-90
The iodine value of an oil is a measure of the amount of iodine that can be absorbed by the oil, indicating its degree of unsaturation or the presence of double bonds in the fatty acid chains. Iodine affects the hardness and conditioning qualities of soap. The lower the Iodine Value, the less conditioning and harder the soap batch will be. Therefore a soap recipe with iodine values higher than 70 will tend to produce a softer batch of soap. The iodine value is expressed in grams of iodine absorbed by 100 grams of the oil. The iodine value of candlenut oil can vary, and specific values may depend on factors such as the source of the oil and the extraction method. Generally, the iodine value for hazelnut oil falls within the range of approximately 80 to 90.
It’s important to note that iodine values are influenced by the fatty acid composition of the oil. Oils with higher iodine values tend to be more unsaturated and may have a greater susceptibility to oxidation. If you need precise information for a specific product or application, it’s recommended to refer to the supplier’s specifications or consult a reliable source for accurate data.
