Ci 17200 / Red 33 Lake ●
TL;DR. This ingredient is a synthetic colorant used to give products a red to pink shade, especially in makeup, tinted skincare, and personal care formulas. In its insoluble form, it is used where stronger opacity, surface payoff, or suspension in an anhydrous base is needed.
What does Ci 17200 / Red 33 Lake do in a cosmetic formula?
This ingredient is a synthetic colorant used to give products a red to pink shade, especially in makeup, tinted skincare, and personal care formulas. In its insoluble form, it is used where stronger opacity, surface payoff, or suspension in an anhydrous base is needed.
Is Ci 17200 / Red 33 Lake clean?
From a clean-beauty perspective, this ingredient often faces scrutiny because it is a synthetic color additive that requires purity control, batch certification, and limits on trace contaminants. It is not a typical irritant at regulated use levels, but many stricter clean standards restrict or exclude synthetic colorants of this class.
Is Ci 17200 / Red 33 Lake sustainable?
This material is generally derived from petrochemical feedstocks and mineral-based substrate chemistry rather than renewable sources. It is not a strong fit for biodegradability-focused formulations, and synthetic colorants in this family can raise aquatic persistence and wastewater-treatment questions.
Is Ci 17200 / Red 33 Lake COSMOS-approved?
This ingredient is not aligned with COSMOS-natural or COSMOS-organic standards, which generally permit only specific mineral pigments and naturally derived colorants. Its synthetic manufacture, limited biodegradability profile, and non-renewable feedstock route place it outside strong Green Chemistry alignment.
How does Ci 17200 / Red 33 Lake work chemically?
It is an organic sulfonated azo colorant rendered water-insoluble by precipitation onto an aluminum salt or alumina substrate, so particle size and dispersion quality strongly affect shade strength and payoff. Use levels are regulation- and product-type-dependent, and the molecule is generally stable across typical cosmetic pH ranges but can shift or fade with strong oxidizers, reducing agents, or incompatible cationic systems.
