Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a liquid cleaning composition that exhibits excellent cleaning power for removing scale deposits on bathroom fixtures such as bathtubs and washbasins, or bathtubs, and is free from solvent odor.

Dirt in the bathroom is generally composed of organic or inorganic substances such as fatty acid metal salts (mainly polyvalent metal salts such as calcium salts), free fatty acids, glycerides, nitrogen-containing compounds, etc. To remove these stains, acid Acidic detergents containing substances, surfactants, and solvents as main components are said to be effective.

However, conventional bathroom cleaners have a strong solvent odor because they use ethylene glycol or diethylene glycol monoalkyl ether as a solvent, and a large amount of fragrance must be added to mask this odor. was there.

As a result of extensive research in order to develop a bathroom cleaning composition that has no solvent odor and has excellent cleaning power,
It was discovered that the desired object could be achieved by blending a terpene-based hydrocarbon solvent selected from monoterpenes and sesquiterpenes as a solvent into a mixture of a surfactant and a hydroxy polyhydric carboxylic acid or a salt thereof, and the present invention was realized. completed.

Therefore, the bathroom liquid cleaning composition according to the present invention includes: (4) Surfactant: 1 to 20 wt%; Terpene-based hydrocarbon solvent selected from monoterpenes and sesquiterpenes; containing 1 to 70 wt% t41! ! It is assumed to be an F sign.

In the present invention, the surfactant used as the (f) component is not particularly limited, and as long as it emulsifies and disperses or solubilizes the component (0) and promotes the wetting and dispersing effects on dirt, Any of anionic, nonionic and amphoteric surfactants can be used. Typical examples of surfactants that can be used as component (1) are as follows.

(B) Anionic surfactant (1) Sulfonate-based linear or branched alkyl (C, ~) benzenesulfonate, long-chain alkyl (C, ~□) sulfonate, etc. (2) Sulfate-based long chain Monoalkyl (Ca~□) sulfate ester salt, polyoxyethylene (1~6 mol) long chain alkyl (C, -xt

~, ) phosphates, etc. 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 Luaone.

(b) Nonionic surfactant polyoxyethylene (1 to 20 mol) long chain alkyl A/(

~20 mol) alkyl (''s, 18) phenyl ether, polyoxyethylene, t? ~, 4) etc., f9 amphoteric surfactant, amino acid type amphoteric surfactant, alkyl sulfo 4-tine,
Each of the surfactants, including those exemplified above, such as betaine-type amphoteric surfactants such as alkyl acetate betaine and imidacilline-type amphoteric surfactants, can be used alone as component (4), or can be used as two or more types. Can also be used in combination. The blending amount of the surfactant is 1 to 20 wt%, preferably 3 to 15 wt% of the cleaning composition.
It is in the range of wt%. If the amount of surfactant is less than 1 wt%, the effect of moistening the dirt and promoting the reaction between the components (to be described later) and the dirt will not be sufficient. On the other hand, blending the surfactant in an amount exceeding 2 Qwt% is not preferable since not only no particular improvement in detergency can be expected, but also deterioration of foaming and rinsing performance.

As the Φ) component of the present invention, a hydroxy polycarzenic acid or a salt thereof represented by the following formula is used.

HOCXYCOOH (wherein, X ij H, CH,, CH, OH, CHlC
OOH or qHOCHCOOHte, Y is H or hacH1
Among the human-hydroxy polycarzenic acids that can be used in the present invention, malic acid and citric acid are particularly preferred. Alkali metal salts such as salts and alkanolamine salts such as monoethanolamine salts, jetanolamine salts, triethanolamine salts are preferred. The blending amount of the active ingredients can range from 1 to 1Qwt% of the detergent composition. l
This is because if the amount is less than 1% by weight, the detergency will be insufficient, and if the amount exceeds 1Qwt%, no particular effect will be brought about in improving the detergency.

Monoterpene hydrocarbons or sesquiterpene hydrocarbons contained in plant aromatic oils are used as the zero component of the present invention.

Examples of monoterpene hydrocarbons include D- or L-limonene contained in orange oil and lemon oil, and α- or β-pinene contained in turpentine oil. , fern oil,
Examples include caryophyllene and cedrene, which are abundantly contained in krono oil and cananga oil. Each terpene hydrocarbon selected from monoterpenes and sesquiterpenes can not only be used alone as the zero component of the present invention, but also can be used as a mixture of two or more types. , pine oil as it is can be incorporated into the composition of the present invention. The appropriate amount of component r) is in the range of 1 to 7 Qwt% of the detergent composition; if it is less than lvt, a satisfactory effect in removing dirt will not be obtained, and if it is more than 80wt%, This has the disadvantage that the stability of the system is impaired.

The liquid cleaning composition of the present invention has the above-mentioned (to) to 0-3
Although these components are essential components, optional components can be added to the composition as necessary. Such optional components include lower alcohols blended to maintain liquid properties at low or high temperatures, hydrotroso agents such as lower alkylbenzenesulfonic acids or salts thereof, polyzolopyrene glycol with a low degree of polymerization, and BHT. (2゜61G 3rd
class zotyl-p-cresol), BHA (butylhydroΦ
Antioxidants such as cyanineol), α-tocopherol, bactericides, preservatives and antifungal agents, pigments, fragrances, and ultraviolet absorbers can be mentioned.

The content of the present invention will be specifically explained below with reference to Examples, but prior to that, a method for evaluating the cleaning agent in the Examples will be described below.

1. Cleaning power for scale stains Sprinkle cleaning solution (undiluted solution) on the scale stains (used for one month) on the bath tub (made of polypropylene) that cannot be easily removed by rubbing, and rub the surface of the tub with a sponge under a load of approximately 50θg. (made of urethane) back and forth 10 times, and visually evaluate the state of dirt removal.
