ABSTRACT:
The present invention relates to liquid, concentrated, homogeneous, stable, heavy duty detergent compositions. Such compositions contain a polyethoxylated nonionic detergent compound, a minor amount of a polyacid having at least one pK value of at least 5.0, and a liquid carrier, whereby the pH of the liquid composition has a pH in the range between 6.0 and 7.5. The compositions can also contain mixtures of polyethoxylated nonionic detergent compounds, additional amounts of synthetic, anionic detergent compounds, minor amounts of brighteners, suds-regulating and pH-regulating agents, perfumes, dyes and other usual liquid detergent compound additives. Such compositions show enhanced cleaning performance, particularly on bleach-sensitive stains, and have excelled stability on storage.
