Acidic limescale removal compositions |
摘要 |
The present invention relates to a liquid acidic composition suitable for removing limescale-containing stains from a hard-surface having a pH below 5, and comprising from 0.01% to 20% of the total composition of a sulfamic acid, from 0.01% to 45% by weight of the total composition of a second acid, and from 0.001% to 10% by weight of an acid-stable polymer selected from the group consisting of a polycarboxylate polymer, a sulphonated homopolymer of (poly) styrene, or a sulphonated copolymer of styrene with an ethylenically unsaturated comonomer, a vinylpyrrolidone homopolymer or copolymer, a polyalkoxylene glycol, and mixture thereof. These compositions provide improved shine to the surface treated as well as improved skin mildness to the user skin while exhibiting effective limescale removal performance. |
