Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a liquid cleaning composition for household use,
Therefore, it has the viscosity and cleaning power that makes it especially suitable for cleaning stubborn stains on walls or ceilings in bathrooms or kitchens, or on vertical surfaces such as toilet bowls, and it does not come with an unpleasant solvent odor. No liquid cleaning composition.

Liquid cleaning agents used for removing stains in kitchens, bathrooms, toilets, etc. are conventionally known to contain surfactants, acids or alkalis, and alkyl ethers such as monoethylene glycol or diethylene glycol as solvents. It is being However, these conventional liquid cleaning agents have almost no viscosity, so when removing stains from walls in the kitchen or bathroom, the sides of the microwave, the door of the refrigerator, etc., the cleaning liquid is applied to areas other than the stained areas. Not only does it drip down, making cleanup troublesome, but the contact time between the cleaning solution and the dirt is also short, which has the disadvantage that the full potential of the cleaning solution cannot be utilized. In addition, conventional liquid cleaning agents have a drawback in that they have a strong solvent odor that is unpleasant to users because they use alkyl ethers such as monoethylene glycol or diethylene glycol as solvents.

As a result of repeated research to solve the conventional problems pointed out above and to develop a liquid cleaning composition for home use that has appropriate viscosity and does not have a solvent odor, the present inventor has identified a surfactant. The present invention was completed based on the discovery that a cleaning agent suitable for the purpose can be obtained by combining a terpene-based hydrocarbon solvent with a viscosity modifier.

Therefore, the viscous liquid cleaning composition of the present invention contains (A) surfactant: 1 to 20 wt%
(B) Viscosity modifier: 0.1-10
wt% (C) A terpene-based hydrocarbon solvent selected from monoterpenes and sesquiterpenes: characterized by containing 1 wt% or more.

In the present invention, the surfactant used as the body component) is not particularly limited, and it emulsifies or solubilizes the component (C) in the composition and has a wetting and dispersing effect on dirt and grime. Any of anionic, nonionic and amphoteric surfactants can be used as long as they promote the reaction.

Typical examples of surfactants that can be used in component (A) are as follows.

(B) Anionic surfactant (1) Sulfonate-based straight or branched alkyl (Csyt) benzenesulfonate, long-chain alkyl (Ca1) sulfonate, etc. (2) Sulfate-based long-chain monoalkyl (Csyt) sulfuric acid Ester salt, polyoxyethylene (1-6 mol) long chain alkyl (Ci5t)
Ni”til sulfate, polyoxyethylene (1~
6 mol) alkyl (Caya) phenyl ether sulfate, (8) phosphate long chain monoalkyl, dialkyl or sesquialkyl (Caya)
syt) phosphate, polyoxyethylene (1-6 mol)
The counter ions (cations) of each of the above anionic surfactants, such as monoalkyl, dialkyl or sesquialkyl (Ca) phosphates, are alkali metal or alkaline earth metal ions such as sodium, potassium, magnesium, etc. It may be any alkanolamine ion such as monoethanolamine, diethanolamine, or triethanolamine.

(C) Nonionic surfactant polyoxyethylene (1-2'0 mol) long chain alkyl (Oaz*) ether, polyoxyethylene (1-20
mole) alkyl (Os, s) phenyl ether, polyoxyethylene polyoxypropylene block polymer, higher fatty acid alkanolamide or its alkylene oxide adduct, long chain tertiary amine oxide (C1, ~
14) etc. (c) Amphoteric surfactant - amino acid type amphoteric surfactant, alkyl sulfobetaine,
Each surfactant, including the typical examples exemplified above, such as tine-type amphoteric surfactants such as alkyl acetate betaine and imidacillin-type amphoteric surfactants, can be used alone as component (A), or as a component (A). It is also possible to combine more than one species to form a captive ingredient. The amount of surfactant to be blended is in the range of 1 to 20 wt%, preferably 3 to 15 wt% of the detergent composition. If this amount is less than 1 wt%, the emulsifying and dispersing effect and solubilizing effect of the surfactant will not be sufficient. On the other hand, if the surfactant is blended in an amount exceeding 20 wt%, it is expected that the cleaning power will be significantly improved. In fact, it is not preferable because it causes the foam to run out and the rinsing properties to deteriorate.

Component (B) of the present invention is a viscosity modifier for imparting viscosity to the composition, and any conventionally known thickener can be used for this. Typical examples include smectite-type clay minerals whose main components are montmorillonite, nontronite, hectorite, vermiculite, attapulgite, ceviolact, and mixtures thereof, which are known as swelling clay minerals, sodium polyacrylate,
Acrylic homopolymer or copolymer such as cross-linked acrylic acid, polyacrylic acid alkyl ester,
Examples include polyvinyl afrecol, hydroxyethylcellulose, carboxymethylcellulose, polyvinylpyrrolidone, maleic anhydride polymer, and the like.

These thickeners can be used alone or in combination of two or more. The amount of clay modifier is in the range of 0.1 to 10 wt., preferably 0.5 to S wt. of the composition. 0.1 wt%
If it is less than that, it will not be possible to impart the necessary viscosity to the composition,
Addition of more than 10 wt% is not desirable as it will excessively thicken the composition.

Monoterpene hydrocarbons or sesquiterpene hydrocarbons contained in plant aromatic oils are used as component (C) of the present invention. Examples of monoterpene hydrocarbons include D- or L-limonene contained in orange oil, lemon oil, etc., and a- or p-pinene contained in turpentine oil. can be exemplified by caryophyllene, cedrene, etc., which are abundantly contained in fern oil, clover oil, and cananga oil.Each terpene hydrocarbon selected from monoterpenes and sesquiterpenes can be used alone in the present invention ( Not only can it be used as component C), but it can also be used as a mixture of two or more types, and furthermore, 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 (C) is as follows:
It is necessary that the amount be 1 wt% or more, and if it is less than 1 wt%, a satisfactory effect in removing oil stains cannot be obtained.

The liquid cleaning composition of the present invention comprises the above-mentioned (4) to (C).
The following three components are essential components, but water can be added to these if necessary, as well as caustic soda, caustic potash, aliphatic amine, morpholine, ammonia, monoethanolamine, jetanolamine, and triethanol. Alkaline substances such as amines or citric acid, malic acid,
Acidic substances such as glycolic acid, sulfamic acid, tartaric acid, and oxalic acid can be added. Furthermore, in order to maintain the liquid properties of the composition at low or high temperatures, lower alcohols such as ethanol, lower alkylbenzenesulfonates such as sodium p-toluenesulfonate, hydrotrosols such as ethylene glycol, propylene glycol, etc. Antioxidants such as BHT (2,6-di-tert-butyl-p-cresol), BHA (butylhuman 0-1-cy7disol), and a'-tocopherol nato, as well as preservatives and preservatives. Mold agents, pigments, fragrances, ultraviolet absorbers, etc. can also be added.
