Cleaning compositions employing extended chain anionic surfactants

摘要

The invention discloses synergistic combinations of surfactants blends and cleaning composition. In certain embodiments a surfactant system is disclosed which includes extended anionic surfactants, linker surfactants, and a multiply charged cation component. This system forms emulsions with, and can remove greasy and oily stains, even those comprised of non-trans fats. The compositions may be used alone, as a pre-spotter or other pre-treatment or as a part of a soft surface or hard surface cleaning composition.

主权项

1. A surfactant system or cleaning composition comprising:
an extended chain anionic surfactant of formula:
R-[L]x-[O—CH2—CH2]y-Mwhere R is a linear or branched, saturated or unsaturated, substituted or unsubstituted, aliphatic or aromatic hydrocarbon radical having from about 6 to 20 carbon atoms, L is a linking group, M is any ionic species, x is the chain length of the linking group ranging from 2-16, and y is the average degree of ethoxylation ranging from 1 to 5, a linker surfactant; and a multiply charged cation component selected from the group consisting of: Ca2+, Mg2 +, a chelating agent, a source of alkalinity, or combination thereof; wherein the cleaning composition is capable of removing oily soils; and wherein said cleaning composition does not contain alkoxylated C8-C20 alcohols or alkyl phenols.
