•
•
Keep young skin flawless. Help aging skin
remain youthful. Formulate systems featuring
challenging anti-aging and blemish-fighting
actives with Carbopol® Ultrez 30 polymer.
This rheology modifier offers good electrolyte
tolerance, high thickening performance in a
broad pH range, and a rich, distinct sensory. It’s
all possible with Carbopol Ultrez 30 polymer.
•
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.

PERFORMANCE IN LOW pH SYSTEMS
Superior Clarity
The broad pH compatibility of Carbopol Ultrez 30 polymer enables the
formulation of low pH systems containing acidic actives such as Alpha
Hydroxy Acids (AHAs) or Beta Hydroxy Acids (BHAs) as well as other low
pH (<4.5) ingredients. Use in combination with nonionic thickeners is
recommended for specific challenging systems at pH 4.0 and below.
Carbopol Ultrez 30 polymer provides high clarity in gel formulations, even
at low pH, so the beauty of suspended actives and optical modifiers can
sparkle through.
