CI 45380 ●
TL;DR. This ingredient is a synthetic colorant used to give cosmetics pink, red, or coral tones. It is most relevant in color cosmetics such as lip products, blush, and decorative formulas.
What does CI 45380 do in a cosmetic formula?
This ingredient is a synthetic colorant used to give cosmetics pink, red, or coral tones. It is most relevant in color cosmetics such as lip products, blush, and decorative formulas.
Is CI 45380 clean?
From a clean-beauty perspective, it has friction because it is a synthetic dye subject to color-additive purity rules and brand-specific restricted lists. Sensitivity is not common at approved use levels, but colorants in this class are often treated more cautiously than mineral pigments.
Is CI 45380 sustainable?
This material is made through synthetic organic chemistry, generally from petrochemical aromatic feedstocks rather than renewable sources. It is used at low levels, but dyes in this class are not strong fits for biodegradability or low-persistence goals.
Is CI 45380 COSMOS-approved?
It is not aligned with COSMOS natural or organic certification as a synthetic organic colorant. From a Green Chemistry lens, petrochemical sourcing, multi-step synthesis, and limited biodegradability make it a weak fit.
How does CI 45380 work chemically?
The molecule is a halogenated xanthene dye, with extended conjugation that creates bright visible color at very low concentrations. It is typically used well below 1% in finished formulas, with shade and performance influenced by pH, salt or lake form, light exposure, and oxidizing or reducing ingredients.
