Science
Mechanism of Action
This ingredient operates through water-soluble compounds, likely including oxalic acid, oxalates, and a rich profile of anthocyanins, which collectively confer broad-spectrum antibacterial and antimicrobial properties, particularly under acidic pH conditions. Its antioxidant effects are attributed to phenols and acetylated anthocyanins, such as malvidin. Furthermore, it has demonstrated capabilities in promoting wound healing, though its anti-inflammatory action was observed to be less pronounced compared to standard pharmaceutical alternatives.

Stability
The antibacterial efficacy of Oxalis Triangularis Water is enhanced in acidic pH environments. While specific numerical optimal pH ranges for overall stability in cosmetic formulations were not identified, its key beneficial activities are pH-dependent.
Safety
Safety Profile
There is currently no formal Cosmetic Ingredient Review (CIR), SCCS, or FDA safety assessment specifically for Oxalis Triangularis Water or its extract as a cosmetic ingredient. However, a topical antibacterial gel containing crude extract was clinically deemed non-irritant during acute dermal toxicity testing. While ingestion of the whole plant in large quantities can be toxic due to soluble calcium oxalates, this concern pertains to internal consumption, not topical application. Third-party databases also list Oxalis Triangularis Extract as 'Irritant Free' and devoid of common allergens.
