Which Carbomer is best for hand sanitizer?
Considering this and our experience, we recommend 0.3–0.6% high viscosity carbomers (Carbopol® Ultrez™ 10, or Carbomer 980) or 0.5–1% medium viscosity types (Carbomer 974) along with aminomethyl propanol as a neutralising agent for the preparation of ABHRs.
How can you tell the strength of gel?
Gel strengths are determined in the two-speed direct-indicating viscometer by slowly turning by hand the driving wheel on the top or side of the instrument and observing the maximum deflection before the gel breaks.
How do you make gel hand sanitizer thicker?

While this reaction is rare, hypersensitive skin types should be aware of the potential irritation. In rare cases, products containing triethanolamine may be contributing to sensitivity.
What are the pharmacotechnical tests for carbopol gel?
The prepared gel was subjected to pharmacotechnical tests such as its pH, viscosity, conductivity, spreadability, centrifugation, and accelerated stability with freezing-thaw cycle. The borneol was successfully incorporated into the carbopol formulation.
What is carbopol gel made of?
Then propylene glycol was added and pH adjusted up to 7 with triethanolamine. The gel was filled in collapsible aluminium tubes. Theory: Carbopol is a synthetic polyacrylic acid with ionizable carboxyl groups. It swells when dispersed in water and hydration helps in the uncoiling of the polymeric chain.
