Trichloroacetic Acid ●
TL;DR. This ingredient is used as a strong chemical exfoliant and skin-resurfacing agent, mainly in professional peel products rather than everyday leave-on cosmetics.
What does Trichloroacetic Acid do in a cosmetic formula?
This ingredient is used as a strong chemical exfoliant and skin-resurfacing agent, mainly in professional peel products rather than everyday leave-on cosmetics.
Is Trichloroacetic Acid clean?
In clean-beauty frameworks, this ingredient carries significant friction because it has high irritation and chemical-burn potential and is typically treated as a professional-use material. It is not a casual complexion active in the way milder alpha hydroxy acids are.
Is Trichloroacetic Acid sustainable?
This material is synthetic and chlorinated, with limited fit for renewable-sourcing narratives. Its environmental profile is less favorable than readily biodegradable, plant-derived acids because halogenated chemistry can raise persistence and aquatic-impact questions.
Is Trichloroacetic Acid COSMOS-approved?
It is not aligned with COSMOS-natural or COSMOS-organic cosmetic formulation principles and is not a typical permitted natural-origin raw material. From a Green Chemistry perspective, its synthetic chlorinated structure, high reactivity, and end-of-life concerns weigh against it.
How does Trichloroacetic Acid work chemically?
The molecule is a small, highly halogenated carboxylic acid with a very low pKa around 0.7, which drives rapid protein coagulation and controlled epidermal injury in peel procedures. Professional peel strengths often range from about 10% to 35%, with very low pH and careful co-formulation needed around neutralizers, water content, packaging compatibility, and operator control.
