Ci 60730/Ext. Violet 2 ●
TL;DR. This ingredient is a synthetic it colorant used to tint products and neutralize yellow or brassy tones, especially in hair-care and color-correcting formulas.
What does Ci 60730/Ext. Violet 2 do in a cosmetic formula?
This ingredient is a synthetic it colorant used to tint products and neutralize yellow or brassy tones, especially in hair-care and color-correcting formulas.
Is Ci 60730/Ext. Violet 2 clean?
It has clean-standard friction because it is a synthetic colorant with regulated use areas and batch-certification requirements in some markets. It is typically used at very low levels, but brands with strict naturally derived or colorant-restriction policies often do not include it.
Is Ci 60730/Ext. Violet 2 sustainable?
This material is made through petrochemical-based dye chemistry rather than renewable agricultural sourcing. Like many synthetic aromatic dyes, it is not a strong fit for biodegradability-focused screening, although total formula levels are usually very low.
Is Ci 60730/Ext. Violet 2 COSMOS-approved?
It is not permitted under COSMOS-natural or COSMOS-organic standards because it is a synthetic organic colorant. Its Green Chemistry profile is limited by nonrenewable feedstocks, multi-step synthesis, and weak biodegradability alignment.
How does Ci 60730/Ext. Violet 2 work chemically?
The molecule is a sulfonated anthraquinone-derived acid dye, which gives strong it color intensity and water compatibility. It is normally used in trace to very low color-correction levels, often below 0.1%, and shade performance depends on pH, ionic strength, and interaction with surfactants or cationic conditioning agents.
