• pH, pH (Neat) - pH is a measure of the acidity or alkalinity of an aqueous solution.
Solutions with a pH less than 7 are considered acidic and solutions with a pH greater than 7 are considered to be alkaline or basic. Neat refers to a solution that is undiluted from its concentrated form.
• Cationic - Refers to a solution that has greater protons than electrons resulting in a positive charge. Cationic sanitizers are self-foaming and generally used for external or environmental sanitizing.
• Solvent Cleaner - Solvented cleaners are used in conjunction or as a replacement for alkaline cleaners. Solvent cleaners are good for removing oils, fats, resins and glues in the food industry.

l ACIDIC– A solution that has a pH less than 7. Acidic solutions in the sanitation industry are used to remove organic soils such as mineral and scale deposits. They are also useful in returning shine or luster to stainless steel surfaces.
l ALKALINE – A solution that has a pH greater than 7. Alkaline solutions in the sanitation industry are used to remove soils such as fats, greases and proteins.
l CHLORINATED – Chemicals that contain sodium hypochlorite (NaOCl). This compound is contained in sanitation chemicals to remove protein soils.
l CAUSTIC– Caustics typically refer to cleaning chemicals that contain sodium hydroxide. These chemicals have a very high pH and are used for heavy duty cleaning applications such as CIP, smokehouses, etc.
l QUATERNARY– Refers to a particular type of sanitizer containing ammonium chloride. Quat sanitizers are self-foaming and provide a bacteriostatic residual film which provides microbial defense for a period of time after it has been applied to an equipment surface.
l MILD – Refers to products that are a neutral pH chemical.
