登记用途：Uses: Used to dye wool、silk、leather、and paper、Also used in wood stains、biological stains、and、indicators、Used as a cosmetic in Western Europe (no contact with mucous membranes) and in Japan (external use only)、[HSDB]、Discontinued use as a color additive for foods、drugs and cosmetics in the US in 1966、Pulp and Paper Processing [Category: Industry]、Leather Tanning and Processing [Category: Industry]、Textiles (Printing、Dyeing、or Finishing) [Category: Industry]、Limited use as a dye for silk and wool fabrics、as biological stain、Use in barium and aluminum lakes that are used as pigments、in wood stain and in paper dyes.、Because of its low lightfastness ... has limited application in both dyeing and printing wool and silk (from an acid bath). Although it dyes fully chromed leather a brilliant green、this application ... is flawed by a low lightfastness.、Guinea Green B is used to dye wool、silk and leather. It is also used to dye paper、in wood stains、as a biological stain and as an indicator. Its barium and aluminum salts are used as pigments. In the past、this color was used as a food、drug and cosmetic dye to color gelatine desserts、frozen desserts、sweets and confections which did not contain fats and oils、bakery products and cereals、and drug capsules. However、its use as color additive for foods、drugs and cosmetics was forbidden in the USA in late 1966、and its use as a food additive was forbidden in Japan in 1967. It is considered to be unsafe for use in food throughout the world.、Use Classification: Food Additives -> COLOUR -> JECFA Functional Classes、Food Additives -> COLOUR -> JECFA Functional Classes、Consumer Uses: Pigment、Methods of Manufacturing:、Guinea Green B、may be prepared commercially by condensing benzaldehyde with alpha-(N-ethylanilino)-meta-toluenesulfonic acid、followed by oxidation and conversion to the sodium salt.、Impurities: In Japan、guinea green B has the following specifications: purity、85% min、inorganic salt、4% max、and water content、10% max.、U.S. Production: 2023: 141、000 lb、2022: 155、2021: 44、500 lb、2020: 2、440 lb、(1973) approx 93、500 kg、General Manufacturing Information: Benzenemethanaminium、N-ethyl-N-[4-[[4-[ethyl[(3-sulfophenyl)methyl]amino]phenyl]phenylmethylene]-2、5-cyclohexadien-1-ylidene]-3-sulfo-、inner salt、sodium salt (1:1): ACTIVE、Guinea Green B has been produced commercially in the USA for over fifty years. Guinea green B was first produced commercially in Japan in 1940. It is believed that there is one producer currently、however、no production has been reported since 1973、when 200 kg were manufactured. There are no Japanese exports or imports of this chemical.、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.。
