Acid Violet 43 (CI 60730) is a chemical compound, a synthetic violet dye with an anthraquinone unit and is known as  o  Ext. Violet 2

Dyes that contain anthraquinone (an organic aromatic compound derived from anthracene) are characteristically bright in colour.

The name describes the structure of the molecule.

CI 60730 is a color code used in the cosmetic and beauty industry to identify specific pigments and dyes. "CI" stands for "Color Index," which is an international system used for classifying colors.

Raw Materials Used in Production.

• CI 60730, or Ext. Violet 2, is a synthetic dye. Typical raw materials include chemical precursors like phthalic anhydride and resorcinol.

Step-by-step Summary of Industrial Chemical Synthesis Process.

• Preparation of Precursors. Phthalic anhydride and resorcinol are common precursors used in the synthesis of CI 60730.
• Condensation Reaction. These precursors undergo a condensation reaction under specific temperature and pressure conditions.
• Oxidation and Purification. The crude product is further processed, oxidized, and purified to achieve the desired dye.
• Drying and Granulation. The dye is then dried and, if needed, granulated into the desired form for commercial use.

Form and Color.

CI 60730 typically appears as a purple crystalline powder or liquid.

What it is used for and where

It is a restricted ingredient as IV/90  a Relevant Item in the Annexes of the European Cosmetics Regulation 1223/2009. Substance or ingredient reported: Sodium 4-[(9,10-dihydro-4-hydroxy-9,10-dioxo-1-anthryl)amino]toluene-3-sulphonate. Not to be used in products applied on the mucous membranes

Cosmetics

Colorant to avoid. It is an ingredient that makes the final product more attractive from an aesthetic point of view, but can pose a potential health risk with undesirable side effects especially when used continuously as it can be absorbed through the skin or mucous membranes.

Safety. 

It is an ingredient that has some important health-related contraindications: it should not come into contact with mucous membranes.
