Product Benefits
  • Effective thickening of ethanol and 2-propanol based hand sanitizers.
  • Structure® 2020 Polymer is a low viscosity, white liquid emulsion of 30% actives - easily pumpable.
  • Thickener product is non-hazardous and carries no warning label.
  • Product mixes easily into the target alcohol.
  • Liquid emulsion thickener allows quicker formulation than when using solids typically used, avoiding lengthy hydration and high shear preparation methods.
  • The emulsion viscosifies and clears upon the addition of alkaline neutralizing agents (such as TEA or AMP) - the resulting viscosified alcohol is water white.
  • Formulated product rheology matches that of market leading technologies.
  • Formulated systems are both viscous and elastic - air bubbles can be held inside the gel.
  • Typical dosage 3-5% active in 70% ethanol. Similar dosage also viscosifies 2-propanol solutions.
  • Formulated gel provides good viscous pump disperser action, spreads easily on hands, providing a luxurious handfeel with rubbing. It dries quickly leaving hands feeling soft.
  • Patent pending.

Storage & Handling

Storage Information
  • Storage tanks should be plastic, fiberglass, or 316 stainless.
  • Pumps should be low-shear type, such as diaphragm or peristaltic type with all wetted parts and lines being stainless steel, plastic or Teflon®.
  • Mild steel, copper, brass and aluminum should not be used.
  • Filtering should be under low shear and volume flow conditions.
  • Freezing should be avoided as it destabilizes the emulsion.
  • The recommended storage temperature is 5-50°C (40-120°F).
  • Dilution or pH adjustment of the product may require additional preservative to prevent biological growth.
  • Keep containers tightly sealed to the prevent emulsion from air drying and forming a film.
