Science
Mechanism of Action
This ingredient operates by significantly reducing the surface tension of a liquid, allowing for the stable mixing of typically separated phases such as oil and water. This property is crucial for effectively lifting and dispersing lipid-based impurities and particulate matter from the skin and hair, facilitating their removal.

Stability
While a precise optimal pH range is not documented, related propylene glycol derivatives generally maintain stability between pH 4 and 10. Formulators should note its potential for decarboxylation in highly acidic conditions, and esterification reactions with hydroxyl-containing compounds, particularly PEGs, at elevated temperatures.
Conflicts
- Compounds containing hydroxyl groups (e.g., polyethylene glycols) at elevated temperatures, due to potential esterification reactions reducing shelf-life.
- Highly acidic environments, which can induce decarboxylation.
Safety
Safety Profile
The CIR Expert Panel has determined PPG-3-DECETH-2 CARBOXYLIC ACID, along with other alkyl PEG/PPG ethers, as safe for use in cosmetics, provided formulations are meticulously developed to be non-irritating. No specific maximum concentration has been set, but emphasis is placed on careful formulation to prevent irritation.
