Solid toilet bowl cleaning composition

Detailed description of the invention

The present invention relates to a solid toilet bowl cleaning composition. More specifically, the present invention provides a solid toilet cleaner composition which can clean the toilet bowl and continuously remove the odor coming out of the toilet bowl by containing the green tea extract and the dissolution regulator containing the flavonoid of (+)-catchin. It is about.

Solid toilet cleaners used in the prior art have a disadvantage in that it does not give a clean feeling due to the limitation of the choice of the cleaning function material and the uneven color as a solid. (See Korean Patent Publication Nos. 92-8173, European Patent No. 084416, 0055100, British Patent No. 1601123, 2021143 and 2061996).

In particular, the existing solid toilet cleaner used the fragrance component for the purpose of blocking the stool smell, but could not remove the odor peculiar to the toilet bowl.

The present inventors have studied to improve the above-mentioned disadvantages of the prior art, and as a result, the use of the extract of Tea sinensis L, which contains the flavonoid of (+)-catechin in the composition of the conventional toilet bowl cleaner, By decomposing the odor component can exhibit a strong deodorizing effect, and also by using a dissolution regulator such as anionic surfactant substituent salt, it has been found that the melt output can be uniform and the service life can be extended to complete the present invention.

The present invention provides a solid toilet bowl composition comprising an anionic surfactant substituent salt and a (+)-catechin-containing green tea extract together with a fatty acid monoethanolamide, a nonionic surfactant, a midpoint agent and a polyoxyethylene glycol derivative. It is about.

Flavonoids are a natural complex mainly contained in camellia plants such as green tea, and polyphenol derivatives are commonly called flavonoids.

Japanese textile machinery (Vol. 40, No. 3, 1987) describes that polyphenol derivatives having a three-dimensional structure and the like trap the molecules or atoms of the malodorous component to remove malodors.

Green tea extract mainly contains components such as caffeine, organic acid, amino acid, (+)-catechin, sugars, etc. Among these components, it is used to capture and decompose (+)-catechin which has three-dimensional structure of polyphenol derivative. This will have the effect of continuously improving the odor.

Flavonoids are represented by the following general formula (I), the surrogate flavonoids are shown in Table 1 below.

ø: ketone group

R Rhamnoside

Ｇ Rhamnoglucoside

이중 = double bond between carbon positions 2 and 3

In general, the flavonoids act directly on the odor source to capture the odor, it is a fast effect of the neutralization decomposition and composed of natural ingredients are completely harmless, has the ability to deodorize each acid to remove only the odor, as well as excellent sterilization effect.

Green tea extract containing (+)-catechin in the solid toilet bowl cleaning composition of the present invention is used to remove the bad smell of the toilet bowl, which is preferably 0.01 to 10% by weight, preferably 0.1 to 7% by weight. If the green tea extract is used at less than 0.01% by weight, it cannot be expected that sufficient odor removal effect can be expected.

(+)-Green tea extracts containing catechins can remove odors from toilet bowls, but dissolution modifiers such as anionic surfactant substituent salts can be used to continuously dissolve the odor removal components at a constant concentration and remove the odor. It is preferable to use together. The anionic surfactant substituent salts used as dissolution modifiers in the detergent compositions of the present invention are calcium substituents of α-olefin sulfonates (Ca-alkylbenzen sulfonate) and alkanesulfo It may be selected from the calcium ring of the nate (Ca-alkane sulfonate). Preferably calcium-alkylbenzene sulfonate is used.

In the cleaning composition of the present invention, an excessive amount of unnecessary inorganic salts can be reduced by reacting the two compositions in advance with an anionic surfactant substituent substituent salt without using an anionic surfactant and an inorganic salt separately.

In addition, the inorganic salts used to prepare the substituent salts are calcium, magnesium, potassium. When preparing the anionic surfactant substitution salt, the reaction ratio of the anionic surfactant and the inorganic salt is used as the weight equivalent ratio. Alkylbenzene sulfonate calcium chloride is used at a weight loading ratio of 5: 1 to 6: 1.

It is preferable to use 5.0-20 weight% of anionic surfactant substituent salt in the cleaning composition of this invention. When the amount of the anionic surfactant substituent salt is 5% by weight or less, the effect of extending the service life cannot be sufficiently expected. When the amount of the anionic surfactant substituent salt is 20% by weight or more, the use of the anionic surfactant substituent salt may be extended, but the dissolution output may be reduced.

In addition, it is preferable that the cleaning composition of the present invention use 5 to 15% by weight of a polyoxyethylene glycol derivative (hereinafter referred to as PEG derivative) which is a main component of the cleaning agent. PEG derivatives in the detergent compositions of the present invention employ those esterified with C stearate with OH groups that are hydrophilic on both sides of PEG. In addition, the detergent composition of the present invention is preferably used 20 to 40% by weight of fatty acid monoethanolamide (hereinafter referred to as CME). If the fatty acid monoethanolamide is 20% by weight or less, the dissolution control is weakened, and when 40% by weight or more, other components cannot be released.

In addition, the cleaning composition of the present invention, it is preferable to use 0.5 to 5% by weight of polyvinyl alcohol (hereinafter referred to as PVA) or gum as a thickener. If the thickener is used in an amount of 5% by weight or more, the product is swelled in water (swellinmg) phenomenon occurs and the product collapses, so it is disadvantageous to use.

In addition, it is preferable that the washing | cleaning material of this invention uses 10-40 weight% of nonionic surfactant which is a main washing | cleaning component. If the content of the bio-ionic surfactant is less than 10% by weight can not be expected sufficient cleaning effect, if more than 40% by weight of a large amount of bubbles may be generated, the cleaning effect after washing may be sharply lowered.

In the cleaning composition of the present invention, as the nonionic surfactant, an alcohol phenolic, fatty alcohol, sorbitan fatty acid derivative, or the like may be used. Particularly preferred are alcohol-based nonionic surfactants having ethylene oxide (EO) addition moles of 10 to 50 to higher alcohols, lauryl with 12 carbohydrates and cetal with 16 carbohydrates.

In addition, it is preferable to use 2 to 15% by weight of the blue No. 1 dye to give a clean image of the cleaning composition of the present invention. When the blue No. 1 dye is used in less than 1% by weight, a clean image appears weak, and when used in more than 20% by weight is too dark may cause rejection.

In addition, it is preferable to use pine oil (pine oil) 0.3 to 5% by weight for the purpose of imparting aroma effect, and when using 0.3% by weight or less of pine oil, the aroma effect is weak and 5% by weight or more. In case of use, the directionality is severe and there is concern about adverse effect.

Hereinafter, the present invention will be described in detail with reference to Examples, but the scope of the present invention is not limited thereto.

[Examples and Comparative Examples]
