HYDROLYZED TAMARINDUS INDICA SEED POLYSACCHARIDE.

Valuable / FILM FORMING, SKIN CONDITIONING, VISCOSITY CONTROLLING

Hydrolyzed Tamarindus Indica Seed Polysaccharide is a sophisticated botanical humectant derived from the tamarind seed, meticulously engineered to provide profound skin hydration and reinforce the epidermal barrier. This multifaceted ingredient actively refines skin texture, enhances elasticity, and contributes to a revitalized, more resilient complexion.

Moisturizer/Humectant Skin-smoothing Film-forming Skin conditioning Viscosity controlling Antioxidant Anti-inflammatory Barrier strengthening Anti-aging Skin regeneration

Science

Mechanism of Action

This polysaccharide functions as a potent humectant, adeptly attracting and retaining water molecules within the skin to deliver intense, long-lasting moisturization. It forms a delicate, invisible film that imparts a protective effect, strengthening the skin's moisture barrier and thereby minimizing transepidermal water loss. Beyond its hydrating capabilities, it actively works to smooth the appearance of fine lines, reduce skin roughness, and improve overall elasticity. The ingredient further supports skin regeneration for an enhanced texture, and exhibits both antioxidative and anti-inflammatory properties. Physiologically, it inhibits β-galactosidase, an enzyme overexpressed in aged keratinocytes, and boosts filaggrin synthesis, which is critical for maintaining skin hydration.

Key findings

  1. 01 After four weeks of application, a 0.5% concentration significantly improved skin hydration by 36%, increased skin elasticity by 19%, reduced skin roughness by 28%, and boosted skin density by 8%. In an immediate comparison, it demonstrated a higher increase in skin hydration compared to sodium hyaluronate within 30 minutes of application.

Stability

Possesses excellent pH-resistance and thermo-stability, performing optimally within a broad pH range of 1.0 to 10.0. While its apparent viscosities and viscoelastic parameters may drastically decrease in strongly alkaline solutions (pH > 10), it remains only slightly influenced by acidic solutions, high temperatures, salt ions, and sucrose. It can be immediately dispersed in cold water, though heating is often required to achieve a uniform solution and maximum viscosity.
