Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a gel-like cleaning composition. More specifically, the present invention relates to a gel-like cleaning composition containing a lanolin fatty acid alkali metal salt, a terpene hydrocarbon and/or isoparaffin hydrocarbon, and a surfactant.

<Prior art> Conventionally, terpene hydrocarbons and/or isoparaffin hydrocarbons are mixed with natural wax esters and/or as gelling agents in the presence of glycols and/or glycol monoethers and/or ethyl alcohol. A gel-like detergent composition obtained by reacting lanolin fatty acid with a caustic aqueous solution and then cooling is known (Japanese Patent Laid-Open No. 19797/1983).

<Problems to be Solved by the Invention> However, when such known gel-like cleaning compositions adhere to hands or substrates during cleaning, they cannot be washed away with water, resulting in discomfort. Furthermore, there was a problem that it was easily recontaminated, making it inconvenient for actual use.

<Object of the Invention> Therefore, an object of the present invention is to provide a gel-like cleaning composition containing a water-soluble terpene hydrocarbon and/or isoparaffin hydrocarbon.

Means for Achieving the Object In order to achieve the above object, the present inventor investigated various additives and found that by adding a specific surfactant, the composition of the cleaning agent can be improved without affecting the gel composition. succeeded in making a substance water-soluble. That is, according to the present invention, a gel-like product containing 2 to 30% by weight of a lanolin fatty acid alkali metal salt, 30% by weight or more of a terpene hydrocarbon and/or isoparaffinic hydrocarbon, and 1.0 to 40% by weight of a surfactant. A cleaning composition is provided.

<Structure of the invention> The present invention will be explained in more detail below.

Surfactants that can be used in the present invention include nonionic surfactants and anionic surfactants. Nonionic surfactants include higher alcohol ethylene oxide adducts, natural alcohols such as coconut oil reduced alcohol, beef tallow reduced alcohol, or Ziegler alcohol;

An adduct containing 30 moles (e.g., product name “Amizet”)
Fatty acid amides of alkanolamides, such as coconut fatty acid or jetanolamide or monoethalamide such as lauric acid or stearic acid (for example, product name "Amizol" manufactured by Yoken Fine Chemical Co., Ltd.), etc. Yes, and polyhydric alcohol type surfactants such as polyethylene glycol type surfactants of higher alkylamine ethylene oxide adducts, fatty acid esters of glycerol, pentaerythritol fatty acid esters, sorbitol and sorbitan fatty acid esters, sucrose esters, and alkyl ethers of polyhydric alcohols. Surfactants can be preferably used in the present invention.

Examples of anionic surfactants that can be used in the present invention include higher alcohol sulfates.

For example, sodium salts or triethanolamine salts of sulfate esters of natural alcohols such as coconut oil reduced alcohol and beef tallow reduced alcohol, or synthetic alcohols such as Ziegler alcohol, oxo alcohol, and secondary alcohols (for example, product name "Emar series" Kao soap) higher alcohol ether (higher alcohol polyethylene glycol ether), for example, a reaction product of the above-mentioned alcohol sulfate ester with polyethylene glycol, such as the product name ``Sanded Series'' manufactured by Sanyo Kasei@), etc.; α-olefin sulfonate, etc. Soda (for example, product name ``Liporan Series'' or ``Soft Detergent'', etc.; sulfonic acid salts such as sulfosuccinic acid diester type, for example, C as an alkyl group)
8912914, single or mixed dialkyl or monoalkyl sulfosuccinate, salts such as jetanolamine or triethanolamine (for example, trade name "Perex series" manufactured by Kao Soap@), etc. can be preferably used, and Sulfated oils, sulfated fatty acid esters and sulfated fatty acids, sulfated ester salts such as sulfated olefins, sulfonates such as sodium alkylbenzenesulfonate, phosphate ester salts, etc. can be used. Any of the above surfactants may be used in combination.

The surfactant can be made water-soluble without affecting the composition of the gel by adding 1 to 40% by weight, preferably 5 to 20% by weight. If the amount of the surfactant is less than 1.0% by weight, the gel-like cleaning composition cannot be made water-soluble, and if it is more than 40% by weight, the stability of the gel will be impaired, which is not preferable.

In the present invention, terpene hydrocarbons and/or isoparaffin hydrocarbons are used in an amount of 30% by weight or more. Preferred terpene hydrocarbons include:

α-pinene, β-pinene, limonene, dipentene, p-
Cymene, 3-carene, γ-terpinene, α-terpinene, myrcene, ocimene, alloocymene.

p-menthane, pinane, terpinolene, 1-p-menthene, camphene, phelandrene, cedrene, caryopylene, humulene, farnesene, limonene dimer, dipentene dimer or their hydrogenated products, or mixtures thereof, or mixtures thereof as main ingredients For example, natural essential oils such as turpentine oil containing α-pinene and β-pinene as a main component, orange oil containing d-limonene as a main component, and lemon oil can be mentioned.

These natural terpene hydrocarbons contain small amounts of oxygen-containing compounds such as alcohols, ketones, aldehydes, etc., but since they do not affect gel formation, mixing of oxygen-containing compounds is not a problem. The isoparaffinic hydrocarbon that can be used in the present invention is represented by the general formula CnH2n+2 (n is an integer from 8 to 20), and is itself non-toxic, has very little odor, has moderate volatility, and is inexpensive. Therefore, it is very preferable as a solvent. Among isoparaffinic hydrocarbons, the characteristic formula is C3H1, ~C, H1゜,
More preferably, C process. H,, -C engineering GH! No. 4 is particularly suitable for the present invention. It is also possible to use a mixture of isoparaffinic hydrocarbons and terpene hydrocarbons. The use of such mixed hydrocarbons is also included in the gel-like cleaning composition of the present invention.

If the terpene hydrocarbon and/or isoparaffin hydrocarbon is contained in an amount less than 30% by weight, a gel-like cleaning composition having the desired cleaning effect cannot be prepared.

If the amount of the above-mentioned terpene hydrocarbon and/or isoparaffin hydrocarbon is less than 30% by weight, the lanolin fatty acid alkali metal salt becomes difficult to dissolve, which is not preferable.

The alkali metal salt of lanolin fatty acid that can be used as a gel agent in the present invention is obtained by adding lanolin fatty acid to a mixture of volatile terpene hydrocarbons, isoparaffinic hydrocarbons, and surfactants, dissolving it under heating, and then adding the alkali metal salt to the mixture. can be formed into the final tissue by dropping an aqueous solution such as caustic soda or caustic potash (preferably such that the amount of water in the final composition is between 0.2 and 15% by weight). . For the cutting blade, lanolin fatty acid alkali metal salt is prepared in advance.

It may be added to a mixture of volatile irpene hydrocarbons and/or isoparaffinic hydrocarbons (surfactants) and dissolved by heating. Furthermore, a lanolin fatty acid alkali metal salt can also be obtained by heating and dissolving lanolin fatty acid in an alcohol such as ethanol, reacting it with an aqueous solution of an alkali metal salt such as caustic soda or caustic potash, and then removing the ethanol and water by evaporation. Lanolin fatty acids contain many isofatty acids and hydroxy fatty acids in addition to straight chain fatty acids. The number of carbon atoms in lanolin fatty acids is widely distributed from 9 to 34, with straight chain fatty acids (cl, -C32) accounting for approximately 7%, isofatty acids (even numbers) accounting for approximately 60%, and antiiso fatty acids (odd numbers). acid) is approximately 30%
Contains. Preferred lanolin fatty acids are those obtained by hydrolyzing lanolin and purified by solvent extraction, molecular distillation, etc. to reduce the characteristic odor. These fatty acids can be produced industrially and are commercially available.

For example, lanolin fatty acid SDO (molecularly distilled) (
Yoshikawa Oil Co., Ltd.■) and others.

In the present invention, in addition to the above components, up to 30% by weight of solvents such as glycols, glycol monoethers, and ethyl alcohol may be mixed and used. Preferred glycols include hexylene glycol,
Propylene glycol, 1,3-butylene glycol,
Dipropylene glycol, diethylene glycol, 1,
6-hexanediol, 1,5-bentanediol, 2
Examples include, but are not limited to, 2-dimethyl-1,3-propanediol and mixtures thereof. The glycol monoethers are preferably glycol monomethyl ether, monoethyl ether, 3-methyl-3-methoxybutanol, or a mixture thereof, but are not necessarily limited to such ethers.

In the present invention, known additives such as metal soaps and antioxidants may be added in addition to the above components.

The gel-like cleaning composition according to the present invention is prepared by placing a lanolin fatty acid alkali metal salt, a terpene hydrocarbon and/or isoparaffin hydrocarbon, and a surfactant in a beaker and heating it until the lanolin fatty acid salt is completely dissolved. Afterwards, a caustic soda aqueous solution is added dropwise to react.

<Effects of the Invention> The gel-like cleaning composition of the present invention has a high ability to dissolve oil stains, and therefore, even though it has a high cleaning power, if it gets on your hands or fingers, it can be easily washed off. .
