CI 15510 ●
TL;DR. This ingredient is a synthetic colorant used to give cosmetic and personal care formulas an orange shade. It is mainly a visual ingredient rather than a skin-care active.
What does CI 15510 do in a cosmetic formula?
This ingredient is a synthetic colorant used to give cosmetic and personal care formulas an orange shade. It is mainly a visual ingredient rather than a skin-care active.
Is CI 15510 clean?
From a clean-beauty perspective, this ingredient has friction because many standards and retailers restrict synthetic azo colorants. The main review points are allowed-use limits, trace aromatic amine impurities, and occasional colorant sensitivity.
Is CI 15510 sustainable?
This material is typically made from petrochemical aromatic feedstocks. It is water soluble, can color wastewater at very low levels, and is not a strong fit for readily biodegradable ingredient design.
Is CI 15510 COSMOS-approved?
This ingredient is not permitted under COSMOS natural or organic standards. Its Green Chemistry alignment is limited because it is synthetic, petrochemical-derived, and has persistence concerns, even though it is used at low levels for color strength.
How does CI 15510 work chemically?
The molecule is a sulfonated synthetic azo colorant, which gives water solubility and strong visible absorbance in the orange range. Use levels are typically very low and controlled by regional color additive rules, with stability depending on pH, light exposure, reducing agents, and compatibility with cationic ingredients.
