Description

Cleaning composition, application thereof and cleaning agent
Technical Field
The invention belongs to the field of cleaning agents, and particularly relates to a cleaning composition, application thereof and a cleaning agent containing the cleaning composition.
Background
The currently marketed shoe washing powder and liquid for washing shoes have two main disadvantages: firstly, dirt on the shoes cannot be removed completely; and secondly, the shoes cleaned by the washing powder and the washing liquid sold in the market are obviously yellow.
In particular, as the living standard of people increases, a spray type shoe washing machine capable of automatically washing shoes has been marketed. The washing powder and the laundry detergent applied to the spray type shoe washing machine for automatically cleaning the shoes also have the two defects.
However, no shoe washing powder or liquid suitable for a spray type shoe washing machine in the prior art has been searched. Therefore, a new formulation is needed for cleaning shoes, especially for spraying type shoe washing machines.
Disclosure of Invention
The invention aims to overcome the defects that shoe washing powder and shoe washing liquid for cleaning shoes in the prior art cannot clean stains on the shoes and the shoes cleaned by applying the currently-sold washing powder and washing liquid are obviously yellow, and provides a novel cleaning agent formula suitable for cleaning the shoes.
The inventor of the present invention found that shoes cannot be cleaned on a spray type shoe washing machine by using commercially available washing powder or laundry detergent, mainly because:
1) the abundant foam hinders the scouring force of water flow to the shoes.
2) The washing powder and the formula of the washing liquid mainly aim at the stains such as blood stains, milk stains, fruit stains, sebum stains and the like of clothes, and the stains on shoes mainly comprise soil, carbon black and grass stains.
In addition, the inventor also finds that the shoes washed by the commercial washing powder are yellow, mainly because the washing powder usually contains alkaline components such as sodium silicate, sodium carbonate and the like, so that the pH value of the washing powder aqueous solution is 9-11 and becomes alkaline. After washing, these alkaline components remain on the surface of the shoe, and cause it to yellow.
In order to achieve the object of the present invention, a first aspect of the present invention provides a cleaning composition comprising a chelating agent, a polymer containing a polyoxyethylene ether segment, an antifoaming agent, a nonionic surfactant, and an anionic surfactant, wherein the polymer containing a polyoxyethylene ether segment is contained in an amount of 1 to 25 parts by weight, the antifoaming agent is contained in an amount of 0.5 to 20 parts by weight, the nonionic surfactant is contained in an amount of 30 to 80 parts by weight, and the anionic surfactant is contained in an amount of 1 to 30 parts by weight, based on 100 parts by weight of the chelating agent; and the polymer containing the polyoxyethylene ether segment is a polyethyleneimine polymer with the weight-average molecular weight of 2000-100000 and/or a polyethylene glycol polymer with the weight-average molecular weight of 100-10000; the chelating agent is at least one of citric acid, sodium citrate, ethylene diamine tetraacetic acid disodium, diethylenetriamine pentaacetic acid pentasodium, sodium tripolyphosphate, polyacrylic acid, sodium polyacrylate, polymethacrylic acid, polymaleic anhydride and fumaric acid-propylene sulfonic acid copolymer.
The inventors of the present invention have found that stains on the upper such as mud, specifically montmorillonite, are a 2:1 type layered aluminosilicate mineral composed of two silicon-oxygen tetrahedral sheets and one aluminum (magnesium) oxygen (hydroxyl) octahedral sheet sandwiched therebetween, and since Al substitutes for Si, there are excessive negative charges in the structure thereof, and therefore exchangeable cations such as Na +, Ca2+, Mg2+ and the like exist between the montmorillonite layers; the chelating agent in the composition of the invention can be combined with the cations in a complexing mode, so that the structure of soil is damaged, and the soil on the vamp is cleaned.
In addition, the polymer containing polyoxyethylene ether chain segments in the composition can accelerate the hydration of soil spots and expand the lamellar structure of soil by being adsorbed on the surface of soil particles, so that the aim of damaging the structure of the soil spots is fulfilled.
Moreover, the defoaming agent can reduce the amount of foam in the shoe washing process to the minimum; thereby the spraying force of the water flow is exerted to the maximum, and the shoe cleaning is facilitated.
A second aspect of the invention provides the use of a composition as described in the preceding first aspect for cleaning footwear.
A third aspect of the invention provides the use of a composition according to the first aspect as hereinbefore described in a spray-on shoe washing machine.
In a fourth aspect of the present invention, there is provided a cleaning agent comprising the composition for cleaning according to the first aspect of the present invention and an additive, wherein the additive is at least one of a solvent, a preservative, an aromatic agent, a deodorant, and a bactericide.
The cleaning composition provided by the invention can effectively remove various stains on shoes when being used for cleaning the shoes, and the shoes cleaned by using the cleaning composition provided by the invention do not have yellowing phenomenon.
