Transparent or slightly opalescent liquid. Is practically colorless and practically odorless. May develop a slight, granular deposit during storage.
Brown, hygroscopic, powdery or easily pulverizable mass. Soluble in water to form a slightly cloudy solution; sparingly soluble in 70 percent alcohol; practically insoluble in alcohol.
White, odorless, tasteless crystals. Soluble in water; practically insoluble in ether, in alcohol, and in acetone.
Colorless to pale yellow, slightly viscous, clear liquid, having a characteristic odor. Refractive index: about 1.423 at 20
. Slightly soluble in water; freely soluble in 1 N sodium hydroxide, in methanol, in alcohol, in acetone, in chloroform, in benzene, in ether, and in n-heptane; slightly soluble in 0.1 N hydrochloric acid.
Orange to orange-red, crystalline powder. Soluble in methylene chloride, in dehydrated alcohol, in methanol, and in acetone; very slightly soluble in water, in hexane, and in petroleum ether.
Tan to brown, free-flowing powder, odorless and having a bitter taste. Freely soluble in water; insoluble in ether and in chloroform.
Tan to brown, free-flowing powder, odorless and having a bitter taste. Freely soluble in water; insoluble in ether and in chloroform.
Fine, white to slightly yellow crystals, usually needle-like, having an odor and taste suggestive of vanilla. Is affected by light. Its solutions are acid to litmus. Slightly soluble in water; freely soluble in alcohol, in chloroform, in ether, and in solutions of the fixed alkali hydroxides; soluble in glycerin and in hot water. NF category: Flavors and perfumes.
Clear, colorless or practically colorless liquid, having a faint, characteristic odor.
White or creamy white crystals, or a crystalline powder. Slightly soluble in water and in acetone; sparingly soluble in alcohol.
Type I Hydrogenated Vegetable Oil—Fine, white powder, beads, or small flakes. Type II Hydrogenated Vegetable Oil—Plastic (semi-solid) or flakes having a softer consistency than Type I. Insoluble in water; soluble in hot isopropyl alcohol, in hexane, and in chloroform. NF category: Type I Hydrogenated Vegetable Oil—Tablet and/or capsule lubricant; Type II Hydrogenated Vegetable Oil—Ointment base.
White or practically white, crystalline powder. Is practically odorless and has a bitter taste. Soluble in water; freely soluble in chloroform; sparingly soluble in alcohol; practically insoluble in ether.
White to off-white powder. Very slightly soluble in water; slightly soluble in dimethylformamide.
White or slightly yellow, odorless, amorphous or crystalline powder. Is hygroscopic. Freely soluble in water.
White to slightly yellow, odorless, amorphous or crystalline powder. Is hygroscopic. Freely soluble in water; soluble in methanol; slightly soluble in alcohol.
Yellowish-white solid, having the characteristic appearance of products prepared by freeze-drying.
White to yellow or light brown, amorphous powder. Freely soluble in water.
In liquid form, a light-yellow to red oil that may solidify upon refrigeration. In solid form, has the appearance of any diluent that has been added. May be practically odorless or may have a mild fishy odor, but has no rancid odor or taste. Is unstable to air and light. In liquid form, insoluble in water and in glycerin; very soluble in chloroform and in ether; soluble in absolute alcohol and in vegetable oils. In solid form, may be dispersible in water.
Practically odorless and tasteless. The alpha tocopherols and alpha tocopheryl acetates occur as clear, yellow, or greenish yellow, viscous oils. d-Alpha tocopheryl acetate may solidify in the cold. Alpha tocopheryl acid succinate occurs as a white powder; the d-isomer melts at about 75, and the dl-form melts at about 70. The alpha tocopherols are unstable to air and light, particularly when in alkaline media. The esters are stable to air and light, but are unstable to alkali; the acid succinate is also unstable when held molten. Alpha tocopheryl acid succinate is insoluble in water; slightly soluble in alkaline solutions; soluble in alcohol, in ether, in acetone, and in vegetable oils; very soluble in chloroform. The other forms of Vitamin E are insoluble in water; soluble in alcohol; miscible with ether, with acetone, with vegetable oils, and with chloroform.
The liquid forms are clear, yellow to brownish red, viscous oils. The solid forms are white to tan-white granular powders. The liquid forms are insoluble in water; soluble in alcohol; miscible with ether, with acetone, with vegetable oils, and with chloroform. The solid forms disperse in water to give cloudy suspensions.
