。DETAILED DESCRIPTION OF THE INVENTION Aqueous inorganic acid solutions, which are strong acids with a pH of 1 or less, are frequently used to clean tiles, drain pipes, toilet bowls, etc. in toilets, washrooms, bathrooms and kitchens. This is because strong acids are highly effective in decomposing and removing dirt. However, with a simple aqueous solution, the cleaning effect is low because it flows and does not adhere to the target surface in a certain amount. This is especially noticeable when cleaning vertical surfaces. This problem can be solved by thickening the inorganic acid aqueous solution. However, the existing
A thickening system of an acidic cleaner containing a large amount of inorganic acid and having a pH of 1 or less had a significant decrease in viscosity and did not maintain the necessary viscosity during use, resulting in insufficient cleaning effect. Therefore, we have invented the acidic cleaner having a pH of 1 or less and having viscosity stability over a long period of time.

トの系ではグアーガム添加後の増粘がみられなかった。The background to the above invention will be described below. The acidic cleaner is expected to adhere a certain amount to the target surface in order to improve its cleaning performance, and for this purpose we attempted to thicken the strong acid below Pehani using various water-soluble polysaccharides. The viscosity was measured at 60 rpm using a BM rotational viscometer after each solution was adjusted to 25°C, and the unit was cps. As a thickener,
Natural water-soluble polysaccharides such as gum arabic, sodium alginate, carrageenan, guar gum, pectin, locust bean gum, xanthan gum, rhamsan gum, unilan gum, gellan gum, and succinoglucan; water-soluble substances such as carboxymethyl cellulose, hydroxyethyl cellulose, and methyl cellulose; Water-soluble polymers such as cellulose derivatives were used. Among these, the viscosity of gum arabic, sodium alginate, carrageenan, pectin, and locust bean gum begins to decrease the moment an inorganic acid is added, regardless of the concentration, and the viscosity does not thicken after a few minutes. It wasn't. In other cases, thickening was observed upon addition. When adding 1% guar gum, inorganic acid 3
Although the viscosity can be increased in systems with concentrations ranging from 10% to 10% by weight, the initial viscosity is about 4,700 cps, whereas after 1 day it is 15% by weight.
cpS had decreased. Further, in the system containing 15% by weight of inorganic acid, no thickening was observed after addition of guar gum.

As mentioned above, guar gum, xanthan gum, rhamsan gum, sea urchin gum, carboxymethyl cellulose, hydroxyethyl cellulose, and methyl cellulose can thicken an inorganic acid aqueous solution with a pH of 1 or less, but they do not have viscosity stability and cannot be expected to have a good viscosity when used. Therefore, it lacks practicality.

s. As a result of trying to thicken inorganic acids with pH below 1 using various water-soluble polysaccharides and water-soluble polymers, we found that only when thickening with succinoglucan did the viscosity remain stable over a long period of time. This led to the completion of a practical acidic cleaner that has a constant viscosity during use and has better cleaning effects than conventional acidic cleaners.

できる為大幅に洗浄効率が上がるものである。C. Effects of the Invention Unlike conventional acidic cleaners that have almost no viscosity, they tend to scatter and adhere to the skin and clothing during use, and because they are not applied in a constant amount to the surface to be cleaned, they run off, resulting in less cleaning effectiveness. In addition, most thickeners cause a decrease in viscosity and the viscosity during use is not constant, and the viscosity could not be expected for inorganic acid systems with a pH of 1 or less. With this invention, the viscosity does not decrease during the inventory period after manufacturing, so a constant viscosity can be expected during use, and not only will it not scatter and attack the skin or clothing, but it can also be applied in a constant amount to the surface to be cleaned. This greatly improves cleaning efficiency.
