CI 15510 / Orange 4 ●
TL;DR. This ingredient is a synthetic colorant used to give products an it shade, especially in water-based personal care formulas. It is present for visual appearance rather than skin or hair performance.
What does CI 15510 / Orange 4 do in a cosmetic formula?
This ingredient is a synthetic colorant used to give products an it shade, especially in water-based personal care formulas. It is present for visual appearance rather than skin or hair performance.
Is CI 15510 / Orange 4 clean?
From a clean-beauty perspective, this material has friction because many clean standards limit synthetic petroleum-derived dyes and scrutinize possible trace impurities from dye manufacture. Its use is tightly regulated by color-additive rules, but it is not usually considered a low-friction clean ingredient.
Is CI 15510 / Orange 4 sustainable?
This compound is typically made from petrochemical aromatic feedstocks through dye chemistry. It is water-soluble, but synthetic azo dyes are not strong biodegradability performers and require responsible wastewater management during manufacturing.
Is CI 15510 / Orange 4 COSMOS-approved?
This ingredient is not permitted under COSMOS-natural or COSMOS-organic standards because it is a synthetic colorant outside the allowed natural or mineral colorant scope. Its Green Chemistry fit is weak due to petrochemical sourcing, multi-step synthesis, and limited biodegradability.
How does CI 15510 / Orange 4 work chemically?
The molecule is an anionic sulfonated azo dye, with aromatic ring systems that create visible it color through extended conjugation. It is normally used at very low color-adjustment levels, often well below 1%, and can be affected by strong oxidizing or reducing systems and by regulatory limits that vary by product type and region.
