Hydrogenated Soybean Oil USP NF Grade

Hydrogenated Soybean Oil is the product obtained by refining, bleaching, hydrogenation, and deodorization of oil obtained from seeds of the soya plant Glycine max Merr. (Fabaceae). The product consists mainly of triglycerides of palmitic and stearic acids.

Packaging and storage: Preserve in tight, light-resistant containers. No storage requirements specified.

A: It meets the requirements of the test for Fatty acid composition.
B: It meets the requirements of the test for Melting range.
Melting range: between 66 and 72 .
Acid value: Dissolve about 10 g of Hydrogenated Soybean Oil, accurately weighed, in 50 mL of a hot mixture of neutralized alcohol and methylbenzene-C7H8 (1:1), add 0.5 mL of PhPh, and immediately titrate, while still hot, with 0.1 N potassium hydroxide to produce a permanent, faint pink color: the acid value so obtained is not more than 0.5.
Peroxide value: not more than 5.0.
Unsaponifiable matter: not more than 1.0%, determined on 5.0 g.
Fatty acid composition: Hydrogenated Soybean Oil exhibits the following composition profile of fatty acids, as determined in the section Fatty Acid Composition.

Carbon-Chain Length No. of Double Bonds Percentage (%)
<14 0 0.1
14 0 0.5
16 0 9–16
18 0 79–89
20 0 1.0
22 0 1.0
18 1 4.0
18 2 1.0
18 3 0.2

Alkaline impurities: Dissolve by gently heating 2.0 g of Hydrogenated Soybean Oil in a mixture of 1.5 mL of alcohol and 3.0 mL of Methylbenzene-C7H8. Add 0.05 mL of bromophenol blue, and titrate with 0.01 N hydrochloric acid to a yellow end-point: not more than 0.4 mL of 0.01 N hydrochloric acid is required.
Water: not more than 0.3%.
Limit of nickel: To pass the test 1 micro-gm per gm.

Hydrogenated Soyabean Oil BP Grade

Ph Eur
Action and use: Excipient.

Product obtained by refining, bleaching, hydrogenation and deodorisation of oil  obtained from seeds of Glycine max (L) Merr. (G. hispida (Moench) Maxim.). The  product consists mainly of triglycerides of palmitic and stearic acids.

Appearance: White or almost white mass or powder which melts to a clear, pale yellow liquid  when heated.
Solubility: Practically insoluble in water, freely soluble in methylene chloride, in light petroleum  (bp: 65-70 °C) after heating and in Methylbenzene-C7H8, very slightly soluble in ethanol (96 per  cent)
