The reference polymer of thickened emulsions
LaboratoryEmulsions with 1% polymerSensory and physico-chemical analysis
Compared with two alginates, xanthan gum serves as the bio-sourced reference polymer: the residual films of the emulsions are similar, but each polymer leaves its own texture signature on application. The study is linked to an alginate producer7.
Paired with a carbomer, adhesive hydrogels
Laboratory8 hydrogelsRheology, adhesion, sensory analysis
Combinations of a type C carbomer with xanthan gum, or with a copolymer carbomer, are the most promising for products that stick to the skin. The two selected hydrogels release about 80% of the model caffeine in 5 hours8.
A historic thickener of liquid formulas
Review2023 review
Xanthan gum is traditionally used as a thickener of liquid formulas and an emulsion stabilizer. Its structure changes with temperature and pH9.
