Phosphorus free low temperature ware wash detergent for reducing scale build-up

摘要

Phosphorus-free detergent compositions are provided. Detergent compositions including an aminocarboxylate, water conditioning agent, source of alkalinity and water beneficially do not require the use of additional surfactants and/or polymers to provide suitable detergency and prevent scale build-up on treated surfaces. The detergent compositions are used with a sanitizer to employ the phosphorus-free detergent compositions for use as low temperature ware wash detergents that beneficially reduce scale build-up. Methods of employing the phosphorus-free detergent compositions are also provided.

主权项

1. A phosphorus-free detergent composition comprising:
from about 0.1-10 wt-% of an aminocarboxylate; from about 0.1-10 wt-% of a water conditioning polymer, wherein said water conditioning polymer is a neutralized polycarboxylic acid; from about 20-80 wt-% of an alkalinity source; from about 20-80 wt-% of water, wherein the ratio of the aminocarboxylate to the water conditioning polymer is from about 1:2 to about 2:1 to provide synergistic reduction or elimination of scale build-up on treated surfaces, wherein the composition does not include phosphorus-containing builders, chelants and/or sequestrants, is phosphorus-free, does not contain surfactants, and is substantially free of nitrilotriacetic acid (NTA), and wherein the detergent composition when employed with a sanitizing composition in a separate application provides an effective sanitizing effect at wash temperatures that are not heated above about 140° F.
