Xanthan “helix type” of structure seen from the top and from the side
SAFAXAN RANGE: STRUCTURE
●Xanthan is made of β-1,4-glycosidic glucose units with side chains containing an acetylated
mannose, a glucuronic acid and a terminal mannose
●Half of the terminal mannose carry a pyruvic acid residue
●Molecular weight is around 4*106
●Synergy with other polysaccharides (see Safimix GX)

Safaxan 200
Competitive xanthan
(200 mesh)
MARCH 2016 │ Development Group

SAFAXAN RANGE: MAIN PROPERTIES
●At rest xanthan molecules adopt an equilibrium : hydrogen bounding creates a network able to
suspend particles, droplets, air bubbles
●
●In presence of stress (movement), molecules are reoriented and the gel is broken
●
●When the flow occurs , the molecules turn toward the current and the viscosity decreases
●
●When the stress is removed, the molecules go back to equilibrium
●

SAFAXAN RANGE: USAGE INSTRUCTIONS
* Usage instructions
●Pre-disperse Safaxan in glycerin
●Once the mixture is homogeneous, add it to the water phase
●Xanthan can be added at room temperature
●It is recommended to use Xanthan in presence of electrolytes (salt stabilizes the helix structure)
●
* Application formulae
●Face, neck, body, eye care formulae
●Hair care formulae
●Sun care, after sun and self-tanning formulae
