Red 34/CI 15880 ●
TL;DR. This ingredient is a synthetic colorant used to give products a red shade, especially in makeup, lip products, and some personal care formulas. Its role is visual color, not skin conditioning or preservation.
What does Red 34/CI 15880 do in a cosmetic formula?
This ingredient is a synthetic colorant used to give products a red shade, especially in makeup, lip products, and some personal care formulas. Its role is visual color, not skin conditioning or preservation.
Is Red 34/CI 15880 clean?
Clean-beauty frameworks often flag this ingredient because it is a synthetic color additive that may require batch certification and impurity controls. Sensitivity is uncommon at normal use levels, but some standards limit synthetic dyes and lakes as a category.
Is Red 34/CI 15880 sustainable?
This material is typically made from petrochemical aromatic feedstocks through synthetic dye chemistry. It is not a strong fit for biodegradability-focused formulas because many synthetic organic pigments are designed to resist breakdown and hold color.
Is Red 34/CI 15880 COSMOS-approved?
It is not permitted under COSMOS organic or COSMOS natural standards as a synthetic organic colorant. Its Green Chemistry alignment is limited by nonrenewable feedstocks, multi-step synthesis, and low biodegradability, even though it is used at low levels.
How does Red 34/CI 15880 work chemically?
The molecule belongs to the synthetic azo colorant family, built around aromatic ring systems that create visible red absorption. It is used at q.s. levels for shade, commonly from trace amounts to around 1% depending on product type and color intensity, and it should be protected from strong oxidizing or reducing conditions.
