CASSIA ANGUSTIFOLIA LEAF.

Valuable CAS 85187-05-9 / SKIN CONDITIONING

A high-performance botanical extract rich in acidic polysaccharides, often utilized as a plant-based alternative to hyaluronic acid for its superior moisture-binding capabilities. It provides a dual-action approach by forming a protective, hydrating film on the skin surface while simultaneously delivering potent antioxidant and anti-inflammatory benefits.

Summary

antioxidant soothing humectant skin-conditioning

Science

Mechanism of Action

This ingredient operates through a multi-pathway approach: its galactomannans act as biomimetic humectants that anchor water to the skin's surface to increase plumpness. On a molecular level, it suppresses the NF-kB signaling pathway to reduce the production of pro-inflammatory cytokines such as IL-1b and TNF-α, while sennosides and flavonoids neutralize reactive oxygen species (ROS) to mitigate oxidative cellular damage.

Key findings

  1. 01 Concentrations of 20-40 µg/mL demonstrated significant immunomodulatory effects by inhibiting nitric oxide and modulating IL-8 and IL-6 expression.
  2. 02 At 484 µg/mL, the extract showed a 58% inhibition of α-glucosidase, supporting metabolic skin health and inflammatory regulation.
  3. 03 In vitro studies at 19 µg/mL (IC50) identified potent antioxidant-driven protective effects against damaged skin cells.
