Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a liquid cleaning composition for residential use, which has excellent cleaning power against stubborn '/Q stains stuck in bathrooms, kitchens, etc., and which is free from unpleasant solvents. The present invention relates to an odorless liquid cleaning composition.

Liquid cleaning agents used for removing stains in bathrooms, kitchens, etc. are conventionally known to contain a surfactant containing an acid or an alkali, and an alkyl ether such as monoethylene glycol or diethylene glycol as a solvent. There is. However, although it has excellent detergency, it has the drawback that it has a strong solvent odor, which causes discomfort to the user, and in order to mask this, a pre-prepared fragrance must be added.

Instead of the above-mentioned solvent, an aromatic terpene-based hydrocarbon solvent without a solvent odor is sometimes blended, but this is also not always sufficient in terms of storage stability.

This invention previously solved the problems of the conventional methods pointed out above.
The present invention was achieved as a result of extensive research aimed at developing a cleaning agent that exhibits excellent cleaning power for cleaning dirt in homes, does not emit an unpleasant solvent odor during use, and has excellent storage stability. That is, the present invention provides a surfactant with a terpene hydrocarbon M selected from monoterpenes and sesquiterpenes as a solvent.
The present invention was completed based on the discovery that a detergent suitable for the intended purpose could be obtained by blending an RA agent and a solvent represented by the general formula [1] below as a storage stabilizer. And the invention is as described in the claims.

The present invention relates to a liquid cleaning composition containing the remainder as a main component.

The surfactant which is the component (A) in the present invention is not particularly limited as long as it can promote wetting of dirt and emulsification and dispersion effect, and it can be used for various types of anionic, nonionic and amphoteric interfaces. Any active agent can be used. Typical examples of surfactants that can be used as the (^) component are listed below.

(b) Anionic surfactant (1) Sulfonate-based linear or branched alkyl (cm~22) benzenesulfonate, long-chain alkyl (C8~, )x sulfonate, etc., (2) Sulfate-based long-chain monomer Alkyl (C*-z□) sulfate ester salt, polyoxyethylene (1 to 6 mol) long chain alkyl (Ca to 2
．． ) Ether sulfate ester salt, polyoxyethylene (1
~6 mol) alkyl (C, ~1.) phenyl ether sulfate, etc., (3) phosphate long chain monoalkyl, dialkyl or sesquialkyl (C
, ~2□) phosphate, polyoxyethylene (1 to 6 mol) monoalkyl, dialkyl or sesquialkyl (C,
) phosphates, etc. However, the counter ions (cations) of each of the above anionic surfactants include alkali metal or alkaline earth metal ions such as sodium, potassium, and magnesium, and monoethanolamine, jetanolamine, triethanolamine, etc. It may be any alkanolamine ion such as ethanolamine.

(B) Nonionic surfactant polyoxyethylene (1 to 20 mol) long chain alkyl ((
-9~2. ) ether, polyoxyethylene (1-20
mole) alkyl (C1~I#) phenyl ether, polyoxyethylene polyoxypropylene block polymer, higher fatty acid alkanolamide or its alkylene oxide adduct, long chain tertiary amine oxide (C1□~
, 4) etc. (c) WI surfactant amino acid type amphoteric surfactant, alkyl sulfobetaine,
Betaine-type amphoteric surfactants such as alkyl acetate betaines, imidacilline-type amphoteric surfactants, etc.

Each surfactant, including the typical examples listed above, is
Each can be used alone as the component (A), or two or more can be used in combination as the component (A). The amount of surfactant blended is 1 to 20 νt% of the cleaning composition.
, preferably in the range of 3 to 15 wt%. This amount is 1
If the surfactant is less than 20 wt%, the emulsifying and dispersing effect and solubilizing effect of the surfactant will not be sufficient. On the other hand, if the surfactant is added in an amount exceeding 20 vt%, no particular improvement in detergency can be expected; This is undesirable because it causes bubbles to run out and the rinsability to deteriorate.

Monoterpene hydrocarbons or sesquiterpene hydrocarbons contained in plant aromatic oils are used as component (8) of the present invention. Examples of monoterpene hydrocarbons include D- or L-limonene contained in orange oil, lemon oil, etc., α- or β-pinene contained in turpentine oil, etc., and sesquiterpene hydrocarbons. Examples of such oils include caryophyllene and cedrene, which are abundantly contained in fern oil, clover oil, and cananga oil. Various terpene hydrocarbons selected from monoterpenes and sesquiterpenes can be used alone in the present invention (
Not only can it be used with component B), but it can also be used as a mixture of two or more, and even orange oil, turpentine oil, and pine oil can be blended as they are in the composition of the present invention. The blending amount of component (B) must be 1 wt% or more of the cleaning composition, and 1 wt%
If it is less than 20% by weight, the effect of preventing unpleasant solvent odor during use and in terms of cleaning properties is insufficient, and if it exceeds 20% by weight, storage stability deteriorates, which is not preferable.

Component (C) of the present invention is a component that stably dissolves component (B) in the composition system and improves oral storage stability. As component (C), in order to stably exist the terpene-based hydrocarbon solvent (B) component in the composition, a compound having appropriate hydrophilicity and lipophilicity represented by the following general formula is suitable. .

General formula % formula %) In the formula, R and R' are H or an alkyl group having 1 to 4 carbon atoms, and when the number of carbon atoms in R + the number of carbon atoms in R' is 1 to 7,
and y is 0-4, and x+y=1-6. R and R'
are both H, X is O and y is 5 to 25.

Examples of storage stabilizers that can be used in component (C) represented by the above general formula are ethylene glycol monoethyl ether, ethylene glycol monobutyl ether, diethylene glycol monomethyl ether, diethylene glycol monoethyl ether, diethylene glycol monobutyl ether, diethylene glycol diethyl ether, and propylene. Examples include glycol monomethyl glycol, tripropylene glycol 7-methyl ether, triethylene glycol-monopropylene glycol 7-methyl ether, and polypropylene glycol.
The blending amount of component (C) is in the range of 1 to 20 wt%, preferably 3 to 15 wt%. If this amount is less than iwt%, the storage stability will be insufficient, and if it exceeds 20wt%, the solvent odor will be strong and no improvement in storage stability will be observed.

The liquid cleaning composition of the present invention comprises the above-mentioned (A) to (D).
The following four components are essential components, and these include alkaline substances such as aliphatic amines, morpholine, ammonia, monoethanolamine, jetanolamine, and triethanolamine, or citric acid, malic acid, and sulfamine. Acidic substances such as acids can be blended.

Furthermore, in order to maintain the liquid properties of the composition at low or high temperatures, hydrotropes such as lower alcohols such as ethanol, lower alkylbenzene sulfonates such as sodium p-toluenesulfonate, ethylene glycol, and propylene glycol are used. BHT (2,
6-di-tert-butyl-P-cresol), BHA (butylhydroxyanisole), α-tocopherol and other antioxidants, preservatives and fungicides, pigments, and fragrances.

Ultraviolet absorbers and the like can also be added.
