If citric acid is contained out of the above range, it may cause a problem of lowering gel strength and sudden dissolution of the internal substance, and if carrageenan and konjac are contained outside of the above range, workability problem may occur due to a sudden increase in viscosity during heating. If the inorganic salt is contained outside the above range may cause a change in manufacturing temperature and gel strength change, if the antifoaming agent is contained outside the above range may cause a problem of transparency and gel strength of the final product If the deodorizing component is contained outside the above range, the gel strength is weakened, which may cause a problem of increased dissolution of the internally-containing material.

In addition, decomposition of the carrageenan may occur due to the hydrolysis of carrageenan at a low pH outside the pH range of the mixture, and may cause a sudden gelation problem at a high pH, and insufficient hydration of carrageenan at a low temperature outside of the temperature range. Due to this decrease in gel strength, problems with thermal denaturation (browning, solidification, etc.) may occur at high temperatures.

In addition, the solution B is 0.1 to 10.0 parts by weight of coconut amidopropyl betaine (2- (2-butoxyethoxy) ethanol [2- (2-butoxyethoxy) ethanol) relative to a total of 100 parts by weight; BDG] It is preferable to contain 0.1-5.0 weight part, fragrance 0.1-5.0 weight part, and food coloring 0.001-0.05 weight part.

If coconut amidopropyl betaine is contained out of the above range, the gel strength may be lowered and a sudden dissolution problem may occur. If 2- (2-butoxyethoxy) ethanol is contained outside the above range, the gel strength may be decreased and suddenly. Dissolution problems can occur.

In addition, the solution C may be prepared by adding the solution B to the solution A and stirring for 10 to 60 minutes while maintaining the temperature range of 65 ~ 85 ℃. If out of the temperature range, it may cause a sudden gelation or sudden evaporation of volatiles, denatured fragrance components, and out of the time range may cause dispersibility and denatured fragrance components.

In one embodiment of the present invention, in the case of the deodorant gel composition for removing the basic odor, using a hydroxy acid, natural amino acids as a buffer to adjust the pH to 4.5 ~ 7.0 to improve the dissolving ability of the malodorous substance, zeolite as a deodorizing component Silicate compounds can be used.

In addition, in another embodiment of the present invention, in the case of the deodorant gel composition for acidic odor removal, using an inorganic anion such as borate ions, phosphate ions, carbonate ions, chelating agents such as EDTA, NTA as a buffer to pH 7.0 to 8.5 By adjusting the solubility of the malodorous substance, the deodorizing component may be used surface modified zeolite, silicate, metal phosphate, metal carbonate, methane oxide.
