Abstract

Stable and clear concentrated cleaning compositions comprising at least one short chain surfactant, optionally in combination with long chain nonionic surfactant and potassium carbonate. The short chain surfactants allow for the formulation of stable compositions without the need for additional stabilizers and are especially effective in cleaning greasy soil; the potassium carbonate provides reduced filming and streaking, especially when an anionic sulfonate short chain surfactant is present.

Dependent claims

A stable and clear concentrated cleaning composition comprising by weight:

(1) from 5% to 30% of short chain surfactant comprising a mixture of (a) nonionic surfactant having the formula C.sub.6-10 (EO).sub.c OH in which c is from 3 to 8 and (b) C.sub.6-10 alkyl sulfonate;
(2) long chain surfactant comprising a mixture of (a) nonionic surfactant having the formula C.sub.12-16 (EO).sub.n H in which n is from about 2 to about 10 and (b) nonionic surfactant having the formula C.sub.12-16 (EO).sub.n H in which n is from about 20 to about 60;
(3) optionally, hydrophobic cleaning solvent having the formula C.sub.2-6 (EO).sub.x (PO).sub.y OH in which x and y are each from 0 to about 2;
(4) from 0.5% to 3% suds suppressant comprising a mixture of C.sub.8-22 fatty acid and 2-alkyl alkanol;
(5) from about 1% to about 4% potassium carbonate;
(6) from about 30% to about 70% water;
and wherein in the above formulae, EO represents an ethoxy moiety and PO represents a propoxy moiety.
