Sea Buckthorn Seed Oil
Also: Hippophae rhamnoides seed oil, Seabuckthorn seed oil, Sea-buckthorn kernel oil.
Calculate a 100 % Sea Buckthorn Seed Oil bar
That is stoichiometry on a measured composition rather than a guess, and it is about as well determined as a published figure: checked against the 35 Codex oils where both fields come from the same standard, the method's median error is 0.90 % and its 90th percentile 2.74 %, with no meaningful bias. The formula page shows the working. If you have a certificate of analysis for your lot, enter its measured value in the calculator and this estimate is set aside.

A bar made of 100 % Sea Buckthorn Seed Oil
Conventional qualities summed from the fatty-acid groups; a single-oil bar is a reference point, not a recipe.
Fatty-acid profile
| Fatty acid | Published range, % | Used | |
|---|---|---|---|
| Palmitic acid | C16:0 · saturated | 7 | 7.0 |
| Palmitoleic acid | C16:1 | ≤ 4 | 4.0 |
| Stearic acid | C18:0 · saturated | ≤ 4 | 4.0 |
| Oleic acid | C18:1 | 17–20 | 18.5 |
| Linoleic acid | C18:2 | 33–36 | 34.5 |
| α-Linolenic acid | C18:3 n-3 | 30–36 | 33.0 |
Where these numbers come from
Figure 1A and accompanying text: fatty-acid composition of mature seed oil across four cultivars.
SEED oil (not the palmitoleic-rich pulp oil; see sea-buckthorn-pulp-oil). Fatty acids are from the open-access PLoS ONE 2012 study of Canadian-grown Hippophae rhamnoides ssp. mongolica (cultivars RC-4, E6590, Harvest Moon, FR-14), Figure 1A, mature seed, % w/w across cultivars: linoleic 33-36, alpha-linolenic 30-36, 18:1 (oleic delta-9 plus vaccenic delta-11 combined) 17-20, palmitic about 7, palmitoleic under 4, stearic under 4. The 'oleic' entry therefore includes cis-vaccenic acid, and the palmitic value is an approximate figure read from the paper's text/figure, not a tabulated mean. Saponification value, iodine value and unsaponifiable matter are NULL: no open-access primary document with measured values for the SEED oil could be opened in this session (the Pure and Applied Biology paper is behind a bot-check, the OCL/ScienceDirect/Wiley-JAOCS papers returned HTTP 403 or are paywalled, and conference-proceedings and reseller specification sheets are outside the allowed source list). Do not reuse the pulp-oil SAP/IV for the seed oil: the seed oil is a linoleic/alpha-linolenic oil and would be expected to have a much higher iodine value than the pulp oil. Melting point not given (liquid oil). INCI not verified on CosIng in this session, left null.
