CASSIA GUM.

Valuable CAS - / BINDING, SKIN CONDITIONING, VISCOSITY CONTROLLING

A botanical galactomannan polysaccharide derived from Cassia tora or Cassia obtusifolia seeds, functioning as both a structural stabilizer and a high-performance skin conditioner. Its unique 5:1 mannose-to-galactose ratio enables the creation of elegant, non-greasy textures while providing significant surface hydration.

Viscosity controlling Emulsion stabilizing Film-forming Skin conditioning Humectant

Science

Cassia Gum operates through a dual-action molecular network; its high molecular weight (200-300 kDa) allows it to form a breathable, non-occlusive film that physically traps moisture while its hydroxyl groups chemically bind water to the stratum corneum. Simultaneously, it builds a three-dimensional rheological framework that prevents lipid phase separation in emulsions.

Key findings

  1. 01 Clinical evaluation at concentrations between 0.1% and 2.0% demonstrates significant reduction in transepidermal water loss (TEWL) and measurable improvements in skin smoothness.
  2. 02 Comparative antioxidant assays indicate that at a 2.5% extract concentration, its radical scavenging activity (DPPH) is on par with or exceeds that of Alpha-tocopherol (Vitamin E).
  3. 03 Stability testing shows that a minimal 0.1% inclusion significantly enhances emulsion integrity for over 12 hours compared to standard stabilizing agents.

Because Cassia Gum is effective as a stabilizer at very low concentrations (0.1%), it is rarely 'dusted' for marketing; however, to achieve therapeutic humectant benefits, concentrations should ideally reach 1.0% or higher.

Stability

Requires heat for full hydration and optimal gel strength. It is sensitive to high electrolyte environments and will lose viscosity if the formulation pH drops below 4.5.
