"preferred", "more preferred", and the like, in the present invention, refer to embodiments of the invention that may provide certain benefits, under certain circumstances. However, other embodiments may be preferred, under the same or other circumstances. Furthermore, the recitation of one or more preferred embodiments does not imply that other embodiments are not useful, nor is it intended to exclude other embodiments from the scope of the invention.

The invention provides a toilet cleaning composition in a first aspect, which comprises the following components in parts by weight: 4-4.5 parts of sodium hypochlorite, 4.5-6.5 parts of alkali metal salt, 3-5 parts of alkyl diphenyl ether disulfonic acid sodium, 0.05-0.2 part of thickening agent, 1-3 parts of chelating agent, 0.005-0.02 part of defoaming agent and 76-92 parts of water.

In a preferred embodiment, the composition comprises, in parts by weight: 4.23 parts of sodium hypochlorite, 5.5 parts of alkali metal salt, 4 parts of alkyl diphenyl ether disulfonic acid sodium, 0.11 part of thickening agent, 2 parts of chelating agent, 0.01 part of defoaming agent and 84.07 parts of water.

Sodium hypochlorite

Sodium hypochlorite is the most common "chlorine" bleaching agent in household washing. Bleaching agents are variants that destroy the coloring system or produce a chromophore. The chemical formula of the sodium hypochlorite is NaClO, and the sodium hypochlorite can be applied to water purification, and can be used as a disinfectant, pulp bleaching, chloramine preparation in the pharmaceutical industry and the like.

The sodium hypochlorite is purchased from Tay chemical Co., Ltd.

Alkali metal salts

The alkali metal salt in the invention refers to alkali metal salt. Alkali metal refers to six metal elements in group ia of the periodic table, except hydrogen (H), namely, lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).

In one embodiment, the alkali metal salt comprises at least one of sodium chloride, potassium chloride.

In a preferred embodiment, the alkali metal salt comprises sodium chloride.

In a more preferred embodiment, the alkali metal salt further comprises sodium bicarbonate.

In one embodiment, the sodium bicarbonate and sodium chloride are present in a weight ratio of (1-1.5): 1.

in a preferred embodiment, the weight ratio of sodium bicarbonate to sodium chloride is 1.2: 1.

the toilet cleaning compositions herein also include sodium bicarbonate, which is added to neutralize acidic soils. The applicant finds that when the weight ratio of the sodium bicarbonate to the sodium chloride is (1-1.5): 1, the cleaning effect of the toilet cleaning composition on various dirt can be improved. It is hypothesized that when the alkali metal salt concentration is low, carbonate ions twist the substrate surface to a negative charge, causing sodium alkyl diphenyl ether disulfonate to be repelled; when the weight portion of the alkali metal is 4.5-6.5, and the weight portion ratio of the sodium bicarbonate to the sodium chloride is (1-1.5): 1, the shielding effect of the electrolyte reduces the electrostatic repulsion between the sodium alkyl diphenyl ether disulfonate and the surface of the base material, and simultaneously, the sodium chloride can continuously compress the double electron layers of the interface, so that the sodium alkyl diphenyl ether disulfonate is more compactly arranged on the surface of the base material, and the addition of the sodium chloride destroys the hydration film around the hydrophilic group of the sodium alkyl diphenyl ether disulfonate, so that the hydrophilicity of the sodium alkyl diphenyl ether disulfonate is weakened, and the sodium alkyl diphenyl ether disulfonate is favorable for diffusing to an oil-water interface. Especially, when the alkyl diphenyl ether disulfonic acid sodium is dodecyl diphenyl ether disulfonic acid sodium, the effect is more obvious.

The present application extends the residence time of the composition on the inclined and vertical surfaces of a toilet or urinal by adding a thickening agent, increasing the detergency. However, the structure of the thickener contains a reducing group (such as ether bond) which reacts with the active free radical to decompose sodium hypochlorite, thereby affecting the stability of the composition.

The present applicants have unexpectedly discovered that the stability of the composition is improved when an alkali metal salt is added, the alkali metal salt comprising at least one of sodium chloride and potassium chloride, and the thickener being xanthan gum, the surmised is that the molecular structure of xanthan gum comprises a main chain of cellulose-like poly β -1, 4-glucopyranose and side chains of three saccharide units, the side chains having a D-glucuronic acid unit and two D-mannose units alternately linked, wherein the C position 2 of one D-mannose unit is linked to the O position 3 of the D-glucose unit in the main chain, the C positions 4 and 6 of the D-mannose units at the end of part of the side chains are linked to an pyruvate group via a ketocarbonyl group, and the C position 6 of the D-mannose units partially linked to the main chain are acylated.
