CI 16035 ●
TL;DR. This ingredient is a synthetic colorant used to give products a red to pink shade. It is mainly present for visual identity rather than skin or hair performance.
What does CI 16035 do in a cosmetic formula?
This ingredient is a synthetic colorant used to give products a red to pink shade. It is mainly present for visual identity rather than skin or hair performance.
Is CI 16035 clean?
This ingredient creates clean-beauty friction because it is a synthetic color additive and is often restricted or excluded by retailer standards that limit artificial dyes. Regulated cosmetic grades must meet purity limits, and sensitivity is uncommon but possible in reactive users.
Is CI 16035 sustainable?
This material is generally made from petrochemical feedstocks through multi-step synthesis. It is water-soluble and can raise wastewater persistence concerns compared with readily biodegradable plant-derived colorants.
Is CI 16035 COSMOS-approved?
This ingredient is not aligned with COSMOS-natural or COSMOS-organic standards because synthetic organic dyes are generally not permitted. From a Green Chemistry view, it scores poorly on renewable sourcing and biodegradability, even though it is used at very low levels.
How does CI 16035 work chemically?
This material is a water-soluble sulfonated monoazo colorant, typically supplied as a sodium salt and used at trace levels, often well below 0.1 percent, to tint gels, liquids, and rinse-off products. It is generally stable in mildly acidic to neutral formulas, but strong oxidizers, reducing agents, and some cationic systems can shift color or reduce clarity.
