Toilet bowl cleaning composition of hydrogel formulation {DETERGENT COMPOSITION FOR TOILET BOWEL WITH HYDROGEL FORM}

The present invention relates to a toilet bowl cleaning composition, and more particularly, by stabilizing the cleaning component in the hydrogel formulation, it is possible to use a long time while releasing a uniform amount of cleaning components during use, and to prevent the drainage of the toilet bowl. And, it relates to a toilet bowl composition of the hydrogel formulation that can be used without a separate container (container).

'Toilet cleaner' is a detergent that allows the cleaning component to be discharged into the stored water when it is immersed in the water tank of the toilet. The cleaning component is introduced into the toilet together with water when the toilet is drained to clean the inner wall of the toilet.

In general, toilet bowl cleaners have a solid phase formulation including surfactants, solubility control agents, fungicides, preservatives and dyes as cleaning ingredients, and a separate container for maintaining the phase stability of the cleaning agent and controlling the dissolution rate of the cleaning ingredients. ) Is being used in the state.

However, such a conventional toilet cleaner has the following disadvantages.

Second, conventional toilet cleaners are not only rapidly dissolved in water and thus have a short service life, and cleaning ingredients are not uniformly eluted during the service life, and thus the cleaning power is deteriorated as the use time passes.

Third, the conventional toilet cleaner is in the form of a solid formulation or in a separate container, so when used, it may cause a toilet breakdown by blocking the drain of the reservoir.

Fourth, the conventional toilet cleaner can not achieve a certain form only by the composition of the composition itself is used in a separate container because the manufacturing cost increases, there is a disadvantage that a separate disposal of the container after use.

In view of the problems of the prior art as described above, an object of the present invention is to be able to use a long time, but to release a uniform amount of cleaning components during use, do not block the drain of the toilet bowl, without a separate container (container) It is to provide a toilet cleaning composition that can be used.
