| 应用领域 | Uses: 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.、As dye、biological stain、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.、Use Classification: Food Additives -> COLOUR -> JECFA Functional Classes、Food Additives -> COLOUR -> JECFA Functional Classes、Methods of Manufacturing: Light Green SF is prepared commercially by condensing ethylbenzylaniline with benzaldehyde、followed by sulphonation and oxidation、and、finally、conversion to the sodium salt.、General Manufacturing Information: 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 ...、Color additives were initially regulated in the United States under the U.S. Department of Agriculture's (USDA) Bureau of Chemistry. In 1906、the Food and Drugs Act was passed by Congress、which prohibited the use of poisonous or deleterious colors in confectionery and the coloring or staining of food to conceal damage or inferiority. In 1927、responsibility of the Food and Drugs Act was transferred to FDA. Increasing government oversight、the Federal Food、Drug、and Cosmetic Act (FFDCA) was passed in 1938 and established the three following categories for colors: FD&C: colors used in foods、drugs and cosmetics、D&C: colors used in drugs and cosmetics when in contact with mucous membranes or ingested、and Ext. D&C: colors used in products applied externally.、Light Green SF has not been produced commercially in Japan since its use as a food color was forbidden in 1970. |
