Tragacanth Gum is a natural plant-derived polysaccharide gum obtained primarily from the dried gummy exudate of species of Astragalus, particularly Astragalus gummifer and related plants. It is also known as Gum Tragacanth, Tragacanth and Astragalus Gum. PubChem lists CAS Number 9000-65-1 for Tragacanth Gum.
Tragacanth Gum is a complex natural polymeric material rather than a single low-molecular-weight compound. It contains water-soluble and water-swellable polysaccharide fractions. When contacted with water, it can swell and produce a viscous colloidal system, making it useful for controlling consistency and stabilizing suitable formulations.
In cosmetic formulations, the INCI ingredient associated with Tragacanth is Astragalus Gummifer Gum. COSMILE Europe identifies its cosmetic functions as binding, emulsion stabilising, film forming, fragrance functional and viscosity controlling.
Tragacanth Gum can increase the viscosity of aqueous formulations after hydration. Its strong swelling behavior makes it useful where a natural gum is required to provide consistency and rheological control.
Published technical data report that a 1% solution can have a viscosity of approximately 3,400 cP, although viscosity is strongly dependent on grade, hydration time, temperature and measurement conditions.
Tragacanth Gum can support the physical stability of suitable emulsion systems. Its thickening and colloidal properties can help maintain formulation structure and reduce separation in appropriately designed cosmetic systems. COSMILE Europe lists emulsion stabilising as one of its cosmetic functions.
Tragacanth Gum can produce a continuous film on skin, hair and nails. This film-forming property makes it suitable for selected cosmetic formulations where a natural polymeric film-forming material is desired.
The gum can help improve cohesion in powdered cosmetic products. COSMILE Europe identifies binding as one of the recognized cosmetic functions of the corresponding Astragalus gummifer gum ingredient.
Tragacanth Gum can be considered for creams, lotions, gels, masks and other skin-care systems where viscosity control, stabilization or film formation is required.
Its film-forming and viscosity-controlling properties allow Tragacanth Gum to be evaluated in selected hair-care and styling formulations. The appropriate grade and concentration depend on the desired texture and performance.
Tragacanth Gum can be used in selected cosmetic makeup systems as a binder, viscosity modifier and film-forming material. It may be particularly useful where a natural gum is required to improve product structure.
Tragacanth Gum is a natural polymer and its technical characteristics vary according to botanical source, harvesting, purification, particle size and processing.
A published reference reports a 1% solution pH of approximately 5.1–5.9 and viscosity of approximately 3,400 cP under specified conditions. These values are reference data and should not automatically be used as universal commercial specifications.
Important commercial quality parameters can include appearance, moisture, ash, pH, viscosity, insoluble matter, particle size, microbiological quality and hydration behavior. The exact limits should be taken from the current TDS/COA of the selected cosmetic grade.
