Solvent Orange 1 is a chemical compound, an orange synthetic dye also known as Food Orange 3, Sudan Orange G, CI 11920
Chemical name: 4-(Phenylazo)resorcinol
What it is used for and where
Cosmetics
It’s an ingredient that makes the final product more aesthetically appealing, but can pose a potential risk to human health with unwanted side effects especially when used continuously as it can be absorbed by the skin or mucous membranes.
Safety
It is forbidden to use in hair dye products. It contains resorcinol.
It’s an azo dye, a class of commercial organic dyes. The problem related to azo dyes (monoazo or diazo) is photocatalytic degradation that leads to possible oxidation and subsequent formation of impurities such as aromatic amines some of which have carcinogenic activity.
