Transparent Xanthan Gum

INCI: Xanthan gum

CAS: 11138-66-2
EINECS: 234-394-2

Chemical name: Polysaccharide (C35 H49 O29) n
Composition: 100% Xanthan Gum
Grade: Food and Pharmaceutical additive

Description
Xanthan Gum is a natural polysaccharide of high molecular weight.
It is industrially produced by the fermentation of pure cultures of the microorganism Xantomonas campestris.
It is the sodium, calcium or potassium salt of a high molecular weight polysaccharide containing D-glucose, D-mannose, D-glucuronic acid and not less than 1.5% pyruvic acid.

Autoignition temperature:> 200ºC Color: white to cream powder
Density: 650-850 kg / m3
Flash point: NA
pH of the solution: 6 - 8 in 25% in water

Concentration of use:
The dose to form gels is 1 - 3%.

Incompatibilities
Incompatible with cationic surfactants and polymers, since they precipitate in solution. The anionic and amphoteric surfactants at concentrations higher than 15% cause the precipitation of xanthan gum in aqueous solution.
Under very alkaline conditions, metal ions such as calcium, cause precipitation of the gum.
