Xanthan Gum
Molecular formula:(C35H49O29)n
Molecular weight:1000000
CAS No.:11138-66-2
Property:Xanthan gum is a polysaccharide, derived from the bacterial coat of Xanthomonas campestris, xanthan gum is a high molecular weight (2-6 million) produced by fermentation of glucose, sucrose, or lactose by the Xanthomonas campestris bacterium under the conditions of special nutrient medium .After the fermentation period, the polysaccharide is precipitated from the growth medium with isopropyl alcohol, dried, and ground into a fine powder. It is white-like or light-yellow free-flowing powder with little foul smell. Later, it is added to a liquid medium to form the gum . As xanthan gum has strong antioxidant and antienzyme effect. The existences of biological activity of enzymes under the conditions still play a role, though in the sodium hypochlorite, hydrogen peroxide.

Acting as an thickener and stabilizer, Industrial Grade Xanthan Gum can be applied to many industrial fields, such as oil drilling, pesticide, pottery & porcelain, printing & dyeing, paint, paper-making, mine-extraction, etc. On more than 20 industries have applied Xanthan gum is used as a food additive and rheology modifier, commonly used as a food thickening agent and a stabilizer, to prevent ingredients from separating.  

Xanthan gum is specially produced as mud additive for oil drilling. Being an environment friendly and high efficiency mud additive, it has an excellent tolerance to a wide range of temperature, pH and salinity. It can extremely increase the mud penetrative rate and suspension ability to the drilling-cuttings. Meanwhile, it can also reduce the pressure loss during drilling, stabilize the well-bore, prevent the damage to oil formation, and improve the efficiency of drilling, work-over and completion.

Packing:Net in 25KG Kraft Bags/Carton Drums.
