Black Currant Seed Oil is a liquid specialty oil dominated by linoleic (47%), linolenic (14%), oleic (11%). Usually added in smaller proportions for its label appeal and skin-feel contribution rather than as a recipe base.
Quick Facts
How Much Lye for Black Currant Seed Oil?
With a SAP value of 0.135, fully saponifying black currant seed oil takes 0.135 grams of sodium hydroxide per gram of oil (at 0% superfat):
| Oil amount | NaOH (0% superfat) | KOH (liquid soap) |
|---|---|---|
| 100 g | 13.5 g | 18.9 g |
| 500 g | 67.5 g | 94.5 g |

Real recipes use a superfat discount (typically 5%) and almost always blend several oils. Always run your full recipe through the Soaply lye calculator rather than weighing lye from a single-oil table.
