Acacia Powder (Gum Acacia)

Acacia Powder (Gum Acacia), also known as gum arabic, is a natural gum derived from the dried exudate of Acacia trees such as Acacia senegal and Acacia seyal. It is widely used in laboratory, food, pharmaceutical, and cosmetic applications for its excellent solubility, stabilizing, and emulsifying properties.​

Description and Properties

Appearance: Fine, neutral-scented, odorless powder, glassy or pale yellow in color​

Solubility: Highly soluble in water, forming clear solutions; insoluble in oils​

Composition: Composed primarily of polysaccharides (arabinose, galactose, rhamnose, glucuronic acid) and calcium, magnesium, potassium salts​

pH: Typically 4.1-5.0 in solution​

Viscosity: Solutions are Newtonian, with viscosity independent of shear rate, and viscous only at high concentrations​

Applications

Used in laboratories as a stabilizer in emulsions and suspensions, and as a protective colloid​

Serves as a binder in pharmaceuticals, tablet coatings, and controlled-release formulations​

Acts as an additive in cosmetics for texture and stability, in food for thickening and emulsification, and in inks and adhesives for its preserving and sensitizing action​

Safety and Handling

Safe for handling in laboratory environments, with common precautions including the use of gloves and avoiding inhalation of dust​

Should be stored in a cool, dry place, protected from contamination and moisture​

Gum Acacia remains a versatile and trusted material for stabilization, thickening, and emulsification across scientific and industrial domains.​
