JPH03182596A - Liquid detergent composition for floor - Google Patents

Abstract

PURPOSE:To obtain the title composition useful for cleaning stains on a surface of a floor made of stone such as terrazzo by using an anionic surface active agent, a nonionic surface active agent, a hydroxyalkylcellulose, and a lower alcohol as constituents each in a specified amount and adjusting the pH to a specified value. CONSTITUTION:The title composition contains 1-5wt.% anionic surface active agent (e.g. a straight chain alkylbenzenesulfonic acid salt), 2-10wt.% nonionic surface active agent (e.g. polyoxyethylene lauryl ether), 0.1-2wt.% hydroxyalkylcellulose, and 1-5wt.% lower alcohol (e.g. ethanol) and has a pH of 9 to 12.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a liquid cleaning composition for floors, and more specifically, a liquid suitable for cleaning stains on stone-shaped floor surfaces such as terrazzo and marble. The present invention relates to a cleaning composition.

[Conventional technology and its problems]

For cleaning floor surfaces, neutral liquid cleaning agents containing anionic and nonionic surfactants, or cleaning agents containing solvents are widely used.

These cleaning agents are suitable for removing stains from floors such as wood and vinyl tiles. However, cleaning performance for stains on stone-shaped floor surfaces such as terrazzo and marble, which have become popular in recent years, is still insufficient.

[Means to solve the problem]

As a result of intensive research by the present inventors to solve the above problems,
The inventors discovered that a detergent containing hydroxyalkyl cellulose has an excellent effect on removing dirt from the surface of stone molds, gives a desirable finish (gloss) to the surface after cleaning, and is less sticky, leading to the completion of the present invention. .

That is, the present invention provides: (a) anionic surfactant 1 to 5% by weight C
b) Nonionic surfactant 2-10% by weight (c)
To provide a liquid cleaning agent for floors containing 0.1 to 2% by weight of hydroxyalkylcellulose (2) 1 to 5% by weight of lower alcohol and having a pH of 9 to 12. be.

Examples of the anionic surfactant as component (a) used in the present invention include alkylbenzene sulfonates, α-olefin sulfonates, alkyl sulfates, alkyl ether sulfates, alkanesulfonates, and the like. Among these, alkylbenzene sulfonates having 9 to 14 carbon atoms are particularly preferred in terms of cleaning performance, cost, and the like. The anionic surfactant is blended in the composition in an amount of 1 to 5% by weight.

Particularly useful nonionic surfactants as the (oral) component used in the present invention are polyoxyethylene alkyl ether, polyoxyethylene alkyl phenyl ether, and the like. The nonionic surfactant preferably has an HLB of 9 or more, preferably in the range of 11 to 13, from the viewpoint of cleaning performance. The nonionic surfactant is blended in the composition in an amount of 2 to 10% by weight.

The above surfactant has a (a)/(b) weight ratio of 1/1 to 1.
It is most preferable to use it within the range of /8 in terms of cleaning performance and foaming performance.

The hydroxyalkylcellulose used as component (c) in the present invention includes hydroxymethylcellulose, hydroxyethylcellulose, and the like. Hydroxyalkyl cellulose has a 1% concentration aqueous solution at 25°C.
Those having a viscosity of ~5000 centivoise and a degree of alkyl substitution (DS) in the range of 0.8 to 1.5 are preferably used. These hydroxyalkylcelluloses have the effect of improving cleaning properties and giving gloss to stone-shaped floor surfaces. No such hydroxyalkyl cellulose is present in the composition.
．． It is blended in an amount of 1 to 2% by weight.

Examples of the lower alcohol as component (2) used in the present invention include ethanol, isopropanol, and the like. These lower alcohols are used as solubilizers, but it is preferable to use ethanol in order to impart a bactericidal effect and improve hygiene. Lower alcohols are blended in the composition in an amount of 1 to 5% by weight. .

The pH of the composition of the invention is adjusted to 9-12.

The pH is preferably adjusted with alkanolamines such as monoethanolamine, jetanolamine, and triethanolamine.

When using the liquid floor cleaning composition of the present invention with high-hardness cleaning water, an aminocarboxylate chelating agent such as nitrilotriacetate or ethylenecyaminetetraacetate is added to the composition in an amount of 0.05 to It is preferable to add 1% by weight.

The liquid floor cleaning composition of the present invention may contain other fragrances, pigments, clouding agents, etc., if necessary.

〔Example〕

The present invention will be explained below with reference to Examples, but the present invention is not limited to these Examples.

Liquid floor cleaning compositions having the compositions shown in Table 1 were prepared, and their cleaning power and practicality were evaluated by the following methods.

Cleaning power evaluation method: A trace amount of oil-soluble pigment Sudan ■ is added to rapeseed oil.
A thin layer of g was applied to a 30 x 30 cm piece of terrazzo with a brush. One drop of a 0.3% aqueous solution of a liquid floor cleaning composition shown in Table 1 was dropped onto the terrazzo piece, the surface of the terrazzo piece was rubbed with a cloth, and the cleaning power was visually judged.

The judgment criteria at this time are as follows.

O: Cleanly removed Δ: A little pink color remains ×: Pink color remains mottled Table 1 Note) *1: No, 2 and 3 are comparative products 2LAS: Linear alkylbenzene sulfonate *3H
EC: Hydroxyethyl cellulose *4B: Abbreviation for balance amount <Practical evaluation method> We asked 40 households with terrazzo floors to use a liquid floor cleaning composition with the composition shown in Table 1. Participants were asked to evaluate the ease of removing dirt, the gloss of the terrazzo surface after cleaning, and the sticky feeling when stepping on the terrazzo surface with bare feet after cleaning.

These evaluation results are shown in Table 2.
