Science
Mechanism of Action
This extract provides intense hydration by leveraging its rich polysaccharide content to attract and retain moisture. Its potent antioxidant capabilities, attributed to vitamin C and flavonoids, protect the skin from free radical damage, thereby helping to mitigate signs of aging like wrinkles and hyperpigmentation. It exhibits anti-inflammatory effects by inhibiting nitrogen monoxide (NO) secretion, reducing inflammation-causing substances such as PGE2, and suppressing the expression of iNOS and COX-2, which helps to soothe irritated skin and reduce redness. Additionally, the presence of Alpha Hydroxy Acids (AHAs) including tartaric, lactic, citric, and malic acids, along with pectin and inverted sugar, contributes to improved skin texture and overall appearance.

The Formula
Formulation
Stability
Formulations, including O/W lotions and nanoemulsions, demonstrate stability and homogeneity within a weak acidic pH range of 4.4 to 5.1. However, the antioxidant efficacy of nanoemulsions can diminish under thermal stress (e.g., heating-cooling cycles). The raw fruit extract is inherently highly acidic (pH as low as 2.0) and requires careful pH adjustment for safe cosmetic formulation.
Safety
Safety Profile
While not formally reviewed by CIR, SCCS, or FDA, studies indicate that formulations containing Tamarindus Indica Fruit Extract at weak acidic pH (4.4-5.1) are considered acceptable and safe for topical application. Clinical assessments of cleansing lotions containing the extract (with 2%w/w tartaric acid content) showed no irritation signs or adverse symptoms after cumulative exposure on human skin. In vitro studies further reported an absence of cytotoxicity.
