TAMARINDUS INDICA SEED GUM.

Valuable CAS 84961-62-6 / EMULSION STABILISING, VISCOSITY CONTROLLING

Tamarindus Indica Seed Gum is a natural polysaccharide derived from tamarind seeds, highly valued for its profound hydrating and protective properties in skincare. It functions as a powerful humectant, significantly increasing skin moisture, and forms a delicate barrier to reduce transepidermal water loss. Beyond hydration, this ingredient provides antioxidant defense and soothing benefits, making it a versatile component for enhancing skin health and resilience.

Science

Mechanism of Action

This ingredient operates primarily as a powerful humectant, actively drawing and locking moisture from the surrounding environment into the stratum corneum, thereby intensively hydrating the skin and replenishing its natural moisture reservoirs. It creates a subtle protective film on the skin's surface, which effectively minimizes moisture evaporation and aids in restoring the skin's integral barrier function. Rich in polysaccharides, phenolic compounds, and polyphenols, Tamarindus Indica Seed Gum exhibits robust antioxidant activity, protecting skin cells from oxidative stress and neutralizing free radicals induced by environmental aggressors. Furthermore, its anti-inflammatory and soothing properties help to calm irritated or sensitive skin, alleviating discomfort, redness, and itching. Its anti-aging benefits stem partly from proanthocyanidins, which are observed to enhance collagen synthesis, leading to a reduction in the appearance of fine lines and wrinkles and improved skin elasticity. The antioxidant content also contributes to skin brightening by addressing hyperpigmentation and promoting a more even skin tone.

Stability

Tamarindus Indica Seed Gum demonstrates exceptional stability across a broad pH range, specifically maintaining resistance between pH 1 and 10, and general stability from pH 3 to 11. It exhibits good thermal stability, even tolerating 120°C sterilization conditions while retaining 65% viscosity. The ingredient forms highly elastic and stable gels over time. While dispersible in cold water, full solubilization typically requires heating, though cold-water soluble versions are available. Viscosity and viscoelastic parameters decrease significantly in alkaline solutions above pH 10. It is insoluble in most organic solvents, including ethanol, methanol, acetone, and ether.
