Science
Mechanism of Action
The extract exerts its benefits through a synergistic action of its rich phytochemical profile, encompassing polyphenols, flavonoids, fatty acids, and sterols. Its antioxidant efficacy is primarily demonstrated by its ability to reduce DPPH radicals, thereby mitigating oxidative stress. Skin brightening is attributed to its capacity for tyrosinase inhibition, which interferes with melanin synthesis. Furthermore, sterols and flavonoids contribute to its observed antimicrobial and anti-inflammatory properties, supporting a healthier skin barrier.

Dusting Analysis
Eichhornia Crassipes Extract is typically used as an active ingredient at effective concentrations (up to 15.0%), indicating it is not a 'dusting' ingredient added for marketing claims at negligible percentages.
The Formula
Formulation
Stability
The extract exhibits versatile solubility characteristics, with lipophilic components extractable using natural vegetable oils such as jojoba, sunflower, olive, and grape seed oils. Aqueous, methanol, ethanol, ethyl acetate, chloroform, and n-hexane extracts have also been successfully prepared, allowing for incorporation into various formulation bases depending on the desired target compounds.
Safety
Safety Profile
While official regulatory status from CIR, SCCS, or FDA is currently 'insufficient data,' comprehensive use tests of cosmetic compositions have consistently reported excellent skin tolerance and an absence of harmful side effects. Skin irritation tests conducted on human volunteers also showed positive results, implying a low irritancy profile. Furthermore, studies in Swiss Albino mice found ethyl acetate, aqueous, and methanol fractionates of the extract to be non-toxic at doses up to 2000 mg/kg body weight. It is important to note that environmental concerns regarding the plant's invasiveness refer to the raw plant in its habitat, not the refined cosmetic extract.
