Use context
Common applications
Food thickening and stabilizing applications where E415 is permitted by local regulations
Beverage suspension and viscosity control after buyer formulation validation
Condiment, dressing, jelly, ice cream, and baked goods formulation support
Industrial thickener use where food grade documentation is not required
Oilfield drilling fluid applications when drilling grade specification is confirmed
Cosmetic formulation use only when cosmetic-grade documentation and impurity limits are confirmed
How we compare
Sourcing options
Request food grade E415 xanthan gum with full COA and food safety documentation.
Request drilling grade xanthan gum separately with oilfield performance specifications.
Request mesh-specific quotation for 40 mesh, 80 mesh, or 200 mesh.
