- 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.
