A polysaccharide extracted from bacteria, capable of giving pseudoplastic gels stable up to 60°C. Vanzan NF-C gels strongly retain water and can be used for the cleaning of surfaces sensitive to water. The gels are more viscous than those obtainable with Klucel G or other celluloses. PHYSICAL AND CHEMICAL PROPERTIES: - pH of a 1% solution: 6-8 - Brookfield’s viscosity of a 0.2% solution: 1300-1700 mPa.s
