Deep-purple powder
Reddish-brown powder
In 2-methoxyethanol 100 mg/mL, ethanol 2 mg/mL, temperature not specified
Soluble in water to a green solution which turns yellowish-brown with HCL and then gradually fades. Addition of NaOH almost completely decolorizes the solution yielding a dull violet preticipate.
In water, 100 mg/mL, temperature not specified
When heated to decomposition it emits very toxic fumes of /nitrogen and sulfur oxides as well as sodium monoxide/.

数据库记载的用途

Dyeing wool directly, nylon from a formic acid bath, silk from an acetic acid, formic acid or sulfuric acid bath and chromed leather. The barium lake is used in paper coatings and printing inks.
In the past, light green SF was primarily used in food and drugs for coloring products such as gelatin desserts, maraschino cherries, ice creams and sherbets, sweets and confections, bakery product and cereals, and gelatin capsules for pharmaceutical preparations; however it is no longer believed to be used in these applications.
Food Additives -> COLOUR -> JECFA Functional Classes
Light Green SF is prepared commercially by condensing ethylbenzylaniline with benzaldehyde, followed by sulphonation and oxidation, and, finally, conversion to the sodium salt.
Benzenemethanaminium, N-ethyl-N-[4-[[4-[ethyl[(3-sulfophenyl)methyl]amino]phenyl](4-sulfophenyl)methylene]-2,5-cyclohexadien-1-ylidene]-3-sulfo-, inner salt, sodium salt (1:2): ACTIVE
Certification of Light Green SF for use as a color additive in foods, drugs or cosmetics was cancelled in the US in 1966 and in Japan in 1970. Light Green SF is not included in the list of colorants permitted for use in food in the European Economic Communities ...
