Usage

Description

SIRIUS SUPRA SCARLET GG is a synthetic dye characterized by its yellow light red color. It is soluble in water, resulting in a light orange to red brown color, and also soluble in ethanol and soluble fiber element. However, it is insoluble in other organic solvents. In the dark, strong sulfuric acid turns it olive brown, while dilution results in a light brown color and black light brown precipitation. When the dye solution is mixed with strong hydrochloric acid, it produces a purple brown color and a black light brown precipitation. The addition of a thick sodium hydroxide solution results in orange brown precipitation.

Uses

Used in Textile Industry:
SIRIUS SUPRA SCARLET GG is used as a dye for textiles due to its ability to produce a range of colors from light orange to red brown in water and its solubility in ethanol. Its resistance to acid and alkali, as well as its light fastness, make it a suitable choice for染色 (dyeing) and printing on fabrics.
Used in Soaping:
SIRIUS SUPRA SCARLET GG is used in soaping due to its resistance to water fading and staining. Its ability to produce a range of colors and its solubility in water make it a suitable choice for coloring soaps and other cleaning products.
Standard:
The standard for SIRIUS SUPRA SCARLET GG includes the following ratings for various properties:
Acid Resistance: ISO 3, AATCC 5
Alkali Resistance: ISO 4, AATCC 3
Light Fastness: ISO 6, AATCC 5
