Solvent Red 23

Solvent Red 23 is an oil-soluble azo dye widely recognized for its ability to provide bright red to red-orange coloration in non-aqueous systems. Owing to its strong hydrophobic character and good solubility in selected organic media, it is commonly used in applications where transparent, vivid coloring performance is required in oils, waxes, solvents, and other low-polarity systems.

Shaanxi Medibridge Biotech Co., Ltd. focuses on supplying high-quality ingredients with stable activity standards and reliable supply support for different industrial and formulation needs.

As an azo dye, Solvent Red 23 functions by physically imparting color to formulations. Its primary mechanistic concern involves its metabolism in biological systems; within mammals, including human skin and gut microbiomes, it can undergo reductive cleavage. This process yields potentially carcinogenic metabolites such as 4-aminoazobenzene and aniline. Furthermore, studies in rat liver have indicated that CI 26100 can downregulate CYP4A protein expression and decrease mRNA expression of PPARα, a nuclear receptor involved in lipid and glucose homeostasis.

Solvent Red 23 is mainly used in industrial non-aqueous systems, such as:

• Waxes and polishes
• Oil-based formulations
• Solvent-based inks and related systems
• Fuel and petroleum-related marking applications
• Other selected industrial coloring uses requiring oil solubility

• Handling

Approved respirator. Chemical safety goggles. Rubber gloves. Use only in chemical fume hood. Safety shower and eye-bath. Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use with adequate ventilation. Minimize dust generation and accumulation. Avoid contact with eyes, skin, and clothing. Avoid ingestion and inhalation.

• Storage

Preserve in tight and light-resistant containers. Store in a cool, dry place. Keep containers tightly closed.

Engineering Controls

Equipped with an eyewash facility and a safety shower. Use process enclosure, local exhaust ventilation, or other engineering controls to control airborne levels.

Personal Protective Equipment

• Eyes: Wear appropriate protective eyeglasses or chemical safety goggles
• Skin: Wear appropriate protective gloves to prevent skin exposure.
• Clothing: Wear appropriate protective clothing to minimize contact with skin.
• Respirators: Wear an approved respirator when necessary.

Solvent Red 23 is best described as a specialty oil-soluble dye for selected industrial non-aqueous applications, where bright coloration and compatibility with hydrophobic systems are required.

Solvent Red 23 should be assessed not only for coloring performance, but also for its intended end use and regulatory suitability. Final application must be reviewed according to local regulations, especially for products involving human contact, food-related use, or other sensitive applications.
