Science
Mechanism of Action
This extract operates by leveraging its high concentration of proanthocyanidins and tannins, which are recognized for their robust antioxidant and free radical scavenging capabilities. These antioxidative effects can help mitigate inflammatory processes within the skin. Additionally, it provides an astringent action, which contributes to temporary skin tightening, and serves as a conditioning agent to support overall skin integrity.

Formulation
Stability
Quebracho extract's solubility varies based on processing; cold-soluble versions are typically sulphited to ensure full dissolution of phlobaphenes, whereas standard or warm-soluble extracts, containing high molecular weight condensed tannins, require temperatures exceeding 35 °C for optimal dispersion. The extract is composed of approximately 95% proanthocyanidin and 5% water-soluble sugars. A 40% aqueous solution of commercial quebracho tannin typically presents a pH of 6.7.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has not evaluated Schinopsis quebracho-colorado wood extract for cosmetic use. While tannins generally hold a 'Generally Recognized as Safe' (GRAS) status for food applications, its specific FDA status for cosmetic inclusion remains undetermined.
