20140308162 | PEROXYCARBOXYLIC ACID BASED SANITIZING RINSE ADDITIVES FOR USE IN WARE WASHING - A concentrated liquid sanitizing and rinse composition containing peroxycarboxylic acid(s) and compatible rinse aid surfactants is disclosed. The sanitizing and rinsing compositions are formulated in a single liquid concentrate, replacing a traditional dual product of a sanitizer and rinse aid. The sanitizing and rinsing chemistries are particularly effective at neutral pHs against gram negative organisms at elevated temperatures. Methods of using the concentrated liquid sanitizing and rinse composition are also disclosed. | 10-16-2014 |
20140346371 | FLUORESCING GEL FORMULATIONS AND THEIR APPLICATIONS - Fluorescing gel formulations are disclosed for monitoring cleaning of a surface. The fluorescing gel formulations are stable, fluoresce under UV light, and do not leave a mark after drying and removal. The compositions include an oppositely charged complexing agent which is used in combination with an anionic or cationic optical brightener. In some embodiments, the compositions include a cationic optical brightener with no complexing agent. | 11-27-2014 |
20150291914 | MODERATELY ALKALINE CLEANING COMPOSITIONS FOR PROTEINACEOUS AND FATTY SOIL REMOVAL AT LOW TEMPERATURES - The present invention comprises chlorinated and non-chlorinated alkaline cleaning compositions for removal of proteinaceous and fatty soils at low temperature, i.e. less than 120° F., with little or no deleterious affect on cleaning performance. According to the invention, applicants have found that adding additional alkalinity makes protein removal more difficult and reducing the amount of alkalinity actually improves performance. According to the invention optimized combinations of chlorine and alkalinity components for low temperature cleaning as well as a surfactant system optimized for low temperature fatty soil removal are disclosed. | 10-15-2015 |
