Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A non-chlorine alkaline cleaning composition in use concentration capable of removing proteinaceous soils and/or fatty soils or mixtures thereof at temperatures of less than 100° F. comprising: from about 250 ppm to about 2000 ppm of an active alkalinity source, wherein said alkaline source comprises one or more of an alkali or alkaline earth metal borate, silicate, carbonate, hydroxide, or phosphate; and from about 50 ppm to about 2000 ppm of a C 14 -C 16 dimethyl amine oxide surfactant. 2. The cleaning composition of claim 1 further comprising one or more of the following: a water conditioning agent, a hydrotrope, an antimicrobial agent, a gelling agent and/or a metal corrosion inhibiting agent.
