Abstract
The present invention relates to a composition in which the pH is raised when diluted in the wash and which composition comprises (1) a surfactant system; (2) an N-containing compound and (3) metal salt from group 1B to 8B of the periodic table and/or a metal salt from group 3A or 4A of the periodic table. The N-compound and metal are believed to form a complex which reduces pH in product, but which raises pH when the complex dissociates in the wash. The invention further relates to a process of creating a pH jump system while laundering or cleaning hard surfaces using such a composition.
