CI 45410/Red 28 ●
TL;DR. This ingredient is a synthetic colorant used to give cosmetics and personal care products a bright pink to red shade. Its role is visual only, not skin-conditioning or preservation.
What does CI 45410/Red 28 do in a cosmetic formula?
This ingredient is a synthetic colorant used to give cosmetics and personal care products a bright pink to red shade. Its role is visual only, not skin-conditioning or preservation.
Is CI 45410/Red 28 clean?
This ingredient has clean-standard friction because many clean frameworks restrict synthetic color additives, especially certified dye systems with batch-certification and impurity controls. It is legally regulated for specific cosmetic uses, but it is not usually treated as a low-concern natural colorant.
Is CI 45410/Red 28 sustainable?
This material is synthetically produced, typically from petrochemical aromatic feedstocks. Its halogenated dye structure raises persistence and wastewater-management concerns compared with readily biodegradable plant or mineral colorants.
Is CI 45410/Red 28 COSMOS-approved?
It is not permitted in COSMOS-natural or COSMOS-organic cosmetics because it is a synthetic organic colorant rather than an allowed mineral or nature-derived colorant. From a Green Chemistry view, it scores poorly on renewable sourcing and biodegradability, even though it is used at very low concentrations.
How does CI 45410/Red 28 work chemically?
The molecule is a water-soluble, anionic, halogenated xanthene colorant that deposits color efficiently at very low formula levels. It is generally compatible with aqueous systems, but shade strength can shift with pH, electrolytes, light exposure, and interactions with cationic ingredients.
