ABSTRACT:
Low pH acidic compositions for uses related generally to chemical, pharmaceutical and cosmetic agents and more particularly, but not limited to, used as bactericides, fungicides, germicides and virucides; all having pH values of less than about 2.0 in their final form. These low pH acidic compositions generally comprise two phases in solution. Phase I comprises from about 2 to about 98 weight percent of varying percentages of several chemical, pharmaceutical and cosmetic substances.
Phase II comprises from about 2 to about 99 weight percent of an active aqueous acidic component having a pH value of less than about 1. This phase II aqueous acidic component is produced by:
(a) admixing from about 5 to about 20 weight percent of a strong acid that has a high degree of dissociation with from about 5 to about 20 weight percent of another strong acid with a lower degree of dissociation, but still classified as strong, in a suitable vessel for an effective period of time to produce a substantially homogeneous acidic mixture; and
b) admixing from about 1 to about 5 weight percent of weaker acids with low degrees of dissociation taken from the families of the hydroxycarboxylic acids or alpha hydroxy acids and from about 1 to about 5 weight percent of a dicarboxylic acid with the aqueous acidic mixture in an effective amount of water to provide an aqueous acidic mixture.
