Citric Acid Us Pat./Brevet Americain: 6 ●
TL;DR. This ingredient is primarily used as a pH adjuster and buffering agent, helping formulas land in a skin-appropriate pH range. It can also support mild chelation by binding metal ions that may affect stability or discoloration.
What does Citric Acid Us Pat./Brevet Americain: 6 do in a cosmetic formula?
This ingredient is primarily used as a pH adjuster and buffering agent, helping formulas land in a skin-appropriate pH range. It can also support mild chelation by binding metal ions that may affect stability or discoloration.
Is Citric Acid Us Pat./Brevet Americain: 6 clean?
From a clean-beauty perspective, this ingredient is well accepted and generally low-friction across standards. Sensitivity is mainly formula-dependent, since very low-pH products can sting or feel irritating on compromised skin.
Is Citric Acid Us Pat./Brevet Americain: 6 sustainable?
This ingredient is commonly produced by fermentation of plant-derived sugars, often from corn, beet, or cane feedstocks. It is readily biodegradable and does not raise persistence or bioaccumulation concerns in typical cosmetic use.
Is Citric Acid Us Pat./Brevet Americain: 6 COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic frameworks when sourced and processed according to the standard. Its fermentation route, biodegradability, and simple pH-control role fit well with Green Chemistry principles.
How does Citric Acid Us Pat./Brevet Americain: 6 work chemically?
The molecule is a small, water-soluble alpha-hydroxy tricarboxylic acid with three dissociable carboxyl groups, which explains its buffering and metal-binding behavior. Typical use is often below 1% for pH adjustment, while higher levels may appear in exfoliating or acidic treatment formats, where final pH drives skin feel and tolerance.
