Ci 17200 / Red 33 ●
TL;DR. This ingredient is a water-soluble colorant used to give products a red to pink tone. It is used in formulas such as cleansers, hair products, and some color cosmetics where a vivid, consistent shade is needed.
What does Ci 17200 / Red 33 do in a cosmetic formula?
This ingredient is a water-soluble colorant used to give products a red to pink tone. It is used in formulas such as cleansers, hair products, and some color cosmetics where a vivid, consistent shade is needed.
Is Ci 17200 / Red 33 clean?
From a clean beauty perspective, this ingredient is a regulated synthetic dye, and many stricter clean frameworks flag synthetic colorants or require batch certification and purity controls. Its main scrutiny is not everyday irritation for most users, but synthetic origin, potential trace impurities, and limited acceptance in natural-positioned standards.
Is Ci 17200 / Red 33 sustainable?
This material is petroleum-derived and made through synthetic dye chemistry rather than renewable agricultural sourcing. It is water soluble, but synthetic azo colorants can raise wastewater and persistence questions depending on treatment conditions.
Is Ci 17200 / Red 33 COSMOS-approved?
It is not aligned with COSMOS-organic or COSMOS-natural standards for natural cosmetics. From a Green Chemistry lens, it has weaker alignment because it relies on nonrenewable feedstocks and synthetic azo chemistry, even though it is effective at very low use levels.
How does Ci 17200 / Red 33 work chemically?
The molecule is an anionic azo dye with sulfonate groups, which gives it strong water solubility and affinity for aqueous formulations. It is typically used at very low color-adjusting levels, and formulation performance depends on pH, ionic strength, light exposure, and compatibility with cationic ingredients that may reduce color clarity or cause complexing.
