CI 15850 ●
TL;DR. This ingredient is a synthetic colorant used to give red to pink tones in makeup, lip products, nail products, and some personal care formulas. Its role is visual color rather than skin benefit or preservation.
What does CI 15850 do in a cosmetic formula?
This ingredient is a synthetic colorant used to give red to pink tones in makeup, lip products, nail products, and some personal care formulas. Its role is visual color rather than skin benefit or preservation.
Is CI 15850 clean?
From a clean-beauty perspective, this ingredient often creates friction because it is a synthetic organic colorant with region-specific approval limits and batch purity requirements. It is not a common irritation driver, but trace impurities and certification restrictions are the main review points.
Is CI 15850 sustainable?
This material is typically made from petrochemical-derived aromatic building blocks and is not readily biodegradable. As a persistent pigment, its sustainability profile is weaker than mineral or plant-derived color options.
Is CI 15850 COSMOS-approved?
This ingredient is not aligned with COSMOS-natural or COSMOS-organic colorant rules, which generally favor approved mineral pigments and nature-derived materials. It has limited Green Chemistry alignment because it is synthetic, non-renewable in origin, and persistent after use.
How does CI 15850 work chemically?
The molecule is an insoluble synthetic organic azo colorant, often used as a lake or salt form to improve dispersion in oils, waxes, and anhydrous color cosmetics. Typical use is low and shade-dependent, and formulators focus on dispersion quality, regulatory grade, particle control, and stability against bleeding or shade shift.
