Abstract
Antimicrobial or non-antimicrobial compositions, sanitizing compositions and other compositions combining use of a propoxylated EO/PO block copolymer surfactant and/or propoxylated polymer in combination with at least one additional anionic and/or nonionic surfactant to provide concentrated compositions having a desired viscoelasticity at an active level of at least 18% are disclosed. Non-antimicrobial applications combining use of a propoxylated surfactant and/or propoxylated polymer in combination with at least one additional anionic and/or nonionic surfactant to provide compositions having a desired viscoelasticity are also disclosed. Methods of using concentrated and use compositions having desired foaming enhancement and stabilization are also disclosed.
