CI 15850/RED 7 ●
TL;DR. This ingredient is a synthetic colorant used to give makeup, lip products, and personal care formulas a strong red hue. It functions mainly as an insoluble pigment or lake, so dispersion quality controls shade strength and evenness.
What does CI 15850/RED 7 do in a cosmetic formula?
This ingredient is a synthetic colorant used to give makeup, lip products, and personal care formulas a strong red hue. It functions mainly as an insoluble pigment or lake, so dispersion quality controls shade strength and evenness.
Is CI 15850/RED 7 clean?
From a clean-beauty perspective, it has significant standards friction because many frameworks flag petroleum-derived synthetic colorants and coal-tar-derived color families. Its regulatory acceptance depends on region, product category, and purity specifications, especially limits on residual metals and aromatic impurities.
Is CI 15850/RED 7 sustainable?
This material is typically made through synthetic aromatic chemistry from nonrenewable feedstocks. It is not considered readily biodegradable, though it is used at low levels and is generally designed to remain insoluble in finished formulas.
Is CI 15850/RED 7 COSMOS-approved?
It is not permitted under COSMOS-natural or COSMOS-organic standards because it is a synthetic organic colorant. Its Green Chemistry fit is weak due to nonrenewable sourcing, multi-step synthesis, and limited biodegradability.
How does CI 15850/RED 7 work chemically?
The molecule is an azo naphthol pigment, often used as an insoluble metal salt or lake, with color produced by extended conjugation and controlled particle dispersion. Use level is formula-dependent, commonly under 1% for tinting and higher in color cosmetics, with stability influenced by particle size, dispersion medium, and pH conditions where the pigment remains essentially insoluble.
