Antioxidant Anti-inflammatory Moisturizer Skin Brightening Skin Barrier Support Wound Healing Antimicrobial Collagen Booster

Science

Mechanism of Action

This botanical ingredient works through a synergistic blend of polyphenols, flavonoids, anthocyanins, and essential vitamins (A, C, E). It provides comprehensive antioxidant protection by neutralizing damaging free radicals, thereby mitigating oxidative stress. Anti-inflammatory actions involve suppressing key inflammatory mediators such as IL-1β, IL-6, and nitric oxide, alongside reducing neutrophil infiltration, which helps to calm redness and irritation. It also supports skin hydration by enhancing moisture retention and strengthens the skin's natural barrier. Further benefits include a potential for brightening through its vitamin C content, demonstrated antimicrobial activity, and a possible role in stimulating collagen production, contributing to overall skin vitality and repair.

Stability

The efficacy of key bioactive compounds like polyphenols and flavonoids is sensitive to environmental factors. Stability studies suggest an acidic pH range (below 7) is optimal for maintaining activity; pH values of 7.0 and 8.0 can significantly decrease flavonoid content by approximately 75% and reduce antioxidant activity by 30-47%. High heat treatment at 100°C for 60-90 minutes also compromises antioxidant activity. Blanching is a processing step that can help stabilize the extract by inactivating browning enzymes. The powder itself exhibits good flow stability, and ultrafine particle size enhances suspension stability. Chitosan nanoparticle encapsulation has been shown to protect polyphenols and boost their antioxidant activity.

0.1%
Sensitization risk Moderate

The Cosmetic Ingredient Review (CIR) and Scientific Committee on Consumer Safety (SCCS) status for IPOMOEA BATATAS LEAF/STEM POWDER is not specifically documented. Human patch tests with ethanolic extracts from old Ipomoea batatas leaves demonstrated irritation in 2 out of 7 subjects at concentrations of 1000 ppm (0.1%) and 5000 ppm (0.5%). This indicates a potential for skin irritation, particularly with extracts from older plant material or at higher concentrations. Extracts from younger leaves are noted to contain more anthocyanins and may pose a lower risk of irritation.

Verdict

Valuable

Ipomoea Batatas Leaf/Stem Powder offers a broad spectrum of skin benefits, including potent antioxidant and anti-inflammatory effects, but requires careful formulation at concentrations below 0.1% to minimize potential irritation, particularly when sourced from older leaf material.
