CASSIA ANGUSTIFOLIA SEED EXTRACT.

Valuable CAS 85187-05-9 / SKIN CONDITIONING

A high-performance botanical polysaccharide derived from the seeds of the Indian Senna plant, renowned for its ability to mimic the moisture-binding properties of hyaluronic acid. It functions as a dual-action hydrator that provides immediate surface smoothing while biologically stimulating the skin's internal repair mechanisms.

Science

This extract utilizes high-molecular-weight galactomannans to form a breathable, protective film on the skin's surface, significantly reducing trans-epidermal water loss (TEWL). At a cellular level, it acts as a 'stress-manager' by lowering cortisol levels in keratinocytes, which in turn triggers the natural synthesis of collagen and endogenous hyaluronic acid.

Key findings

  1. 01 Ex vivo testing at 5% concentration demonstrated a 99% surge in internal hyaluronic acid synthesis and a 13% boost in collagen production.
  2. 02 Clinical trials recorded a 44% increase in skin hydration within 30 minutes of application.
  3. 03 Research shows a 61% reduction in skin damage caused by cortisol-induced stress.

Because it is marketed as a 'botanical hyaluronic acid,' it is frequently included in formulas at trace amounts (below 1%) for marketing claims. To achieve the documented 99% increase in HA synthesis, a concentration closer to 5% is required.

Stability

Highly stable across a wide pH range, but sensitive to high heat. It must be incorporated during the cooling phase (below 40°C) to maintain the integrity of its long-chain polysaccharides.
