KEY BENEFITS

• Excellent rheology and suspension performance• Efficient thickening:

• At low use levels (0.1 - 0.2 wt%) when formulated in electrolyte-free systems

• At increased use levels in systems containing high levels of electrolytes

• Able to thicken over a broad pH range, including in low pH systems (pH 4.0 - 5.5)

• Electrolyte tolerance• Rich sensory• High clarity in gels• Easy to use

HIGH THICKENING EFFICIENCY

Carbopol Ultrez 30 polymer provides excellent viscosity at low concentrations in systems containing low to medium levels of electrolytes.
