Zusammenfassung:Disclosed is a dissolvable solid article, comprising by weight of the article: from about 10% to about 50% of a water soluble polymer; from about 20% to about 80% of a surfactant; from about 0.5% to about 2% of diaminocarboxylic acid chelants and salts thereof having an average molecular weight in acid form of from about 250 to about 450 daltons and having a weighted log P value at pH 4 of from about −12 to about −7; from about 0.1% to about 6% of an aromatic carboxylic acid and salts thereof having an average molecular weight in acid form of from about 100 to about 400 daltons and having a weighted log P value at pH 4 of from about −2 to about 4; from about 0.1% to about 18% of an non-aromatic organic alpha hydroxy acid and salts thereof; wherein the dissolvable solid article has a pH of from about 3 to about 5.1 when dissolved with 30 parts water to 1 part of the dissolvable solid article. The present invention provides dissolvable solid articles which provide anti-bacterial benefit even after dissolution of the articles, while controlling the concentration of anti-bacterial active ingredients in the solid articles.
