Carbopol® Ultrez 30 polymer

INCI Name: Carbomer

Carbopol® Ultrez 30 polymer is a white powder, cross-linked homopolymer of polyacrylic acid that is polymerized in a toxicologically-preferred cosolvent system. It offers good electrolyte tolerance, high thickening performance in a broad pH range, and a rich, distinct sensory in challenging skin care formulations. Carbopol Ultrez 30 polymer allows the formulator to achieve desired rheological and aesthetic properties in the presence of electrolytes or acidic actives required for consumer products. Its high electrolyte tolerance and broad pH compatibility make it ideal for formulating products with botanical extracts or water-soluble salts, as well as acidic ingredients such as alpha hydroxy acids, salicylic acid, or organic acid preservatives at a pH range as low as 4.0 - 4.5.


  • Easy to use, enabling efficient handling and manufacturing
  • Electrolyte tolerant at higher polymer levels, allowing for the creation of formulations with pleasant aesthetics in systems containing electrolytes
  • Offers a pleasant sensorial experience with its rich creamy sensory and high clarity in gels
  • Offers excellent rheology and suspension in challenging acidic or electrolyte containing skin care systems
  • Thickens efficiently at low levels (0.1-0.2 wt%) in electrolyte-free systems, making it a good candidate for formulating simple chassis
  • Thickens over a broad pH range (pH 4.0-12.0), enabling potential applications with active ingredients at low or high pH
