Abstract
Aqueous acid cleaning compositions well adapted, e.g., for the descaling of metallic face surfaces include (i) water, (ii) a carboxylic acid dissolved therein having a dissociation constant pK, at 25.degree. C., of at least 2, (iii) a stabilizing amount of at least one salt of an acid having a pK value of at least 2, and of a strong base, and (iv) a thickening amount of a polysaccharide.
Claims12
An aqueous acid composition of matter, comprising (i) water, (ii) a carboxylic acid dissolved therein having a negative log of the dissociation constant (pK), at 25.degree. C., of at least 2, (iii) a stabilizing amount of at least one salt of an acid having a pK value of at least 2, and of a strong base, and (iv) a thickening amount of a polysaccharide.
