CI 47005 ●
TL;DR. This ingredient is a synthetic colorant used to give formulas a yellow to green-yellow hue. It is used for visual identity rather than skin, hair, or cleansing performance.
What does CI 47005 do in a cosmetic formula?
This ingredient is a synthetic colorant used to give formulas a yellow to green-yellow hue. It is used for visual identity rather than skin, hair, or cleansing performance.
Is CI 47005 clean?
From a clean-beauty perspective, this ingredient often creates friction because it is an artificial color additive subject to regulatory purity specifications and positive-list approval. Sensitivity reactions are uncommon, but some standards restrict synthetic dyes because of impurity and sourcing concerns.
Is CI 47005 sustainable?
This material is typically made from petrochemical-derived feedstocks and used at very low levels. It is not a strong fit for biodegradability-focused standards, since synthetic colorants can show aquatic persistence depending on wastewater treatment conditions.
Is CI 47005 COSMOS-approved?
This ingredient is not permitted under COSMOS-natural or COSMOS-organic standards for cosmetic coloring. Its synthetic origin, limited renewable-feedstock alignment, and weaker biodegradability profile make it a poor fit with Green Chemistry preferences.
How does CI 47005 work chemically?
The molecule is a sulfonated synthetic dye, which gives it water solubility and strong visible color at very low use levels. It is generally used in trace amounts for shade adjustment, and formulators must account for regulatory color-additive limits, pH-dependent shade behavior, and possible staining in aqueous systems.
