CI 45350 ●
TL;DR. This ingredient is a synthetic colorant used to add yellow to greenish-yellow tone, often with fluorescent brightness, in cosmetics and personal care formulas. Its role is visual only, not skin-conditioning or performance-driven.
What does CI 45350 do in a cosmetic formula?
This ingredient is a synthetic colorant used to add yellow to greenish-yellow tone, often with fluorescent brightness, in cosmetics and personal care formulas. Its role is visual only, not skin-conditioning or performance-driven.
Is CI 45350 clean?
Clean-beauty frameworks often scrutinize it because it is a synthetic dye and may be restricted by product type, region, and purity specifications. It is regulated for color-additive use, but it carries more clean-standard friction than mineral pigments or plant-derived colorants.
Is CI 45350 sustainable?
This material is typically made from petrochemical aromatic feedstocks through multistep synthesis. It is not a strong fit for biodegradability-focused sourcing, and synthetic dyes can raise wastewater-management concerns during manufacture.
Is CI 45350 COSMOS-approved?
It is not permitted in COSMOS-natural or COSMOS-organic products because it is a synthetic colorant outside the standard’s allowed colorant approach. From a Green Chemistry view, it has weaker alignment due to nonrenewable feedstocks, multistep processing, and limited biodegradability.
How does CI 45350 work chemically?
The molecule belongs to a highly conjugated xanthene dye family, which gives strong color intensity and pH-sensitive fluorescence. It is normally used at trace colorant levels, often well below 0.1%, with final limits governed by local color-additive regulations and product category.
