Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a liquid detergent composition that can be widely used as a laundry detergent, a dishwashing detergent, a household detergent, a hair detergent, a human body detergent, etc. The present invention relates to a liquid cleaning composition with improved properties.

[Conventional technology and problems]

Conventionally, detergent surfactants have been consistently selected for liquid detergents, such as dishwashing detergents and hair detergents, from the viewpoints of fighting power, foaming power, skin gentleness, and storage stability. There is.

Usually, anionic, nonionic and amphoteric surfactants are used alone or in combination of two or more. In general, anionic surfactants have superior detergency and foaming power compared to nonionic surfactants and amphoteric surfactants, but on the other hand, they tend to be more irritating to the skin and have poor rinsing properties, so they are not satisfactory. It wasn't possible. On the other hand, nonionic surfactants and amphoteric surfactants have low skin irritation, but have insufficient cleaning power, foaming power, and rinsing performance.
Each had advantages and disadvantages. In order to improve these drawbacks, methods of combining anionic surfactants and nonionic surfactants, or anionic surfactants and amphoteric surfactants, etc., have been extensively studied. For example, in Japanese Patent Publication No. 38-3264, a method was proposed in which higher alcohol ether sulfate was used in combination with tertiary amine oxide to improve its fighting power and foaming power while suppressing skin irritation.
It is disclosed in Japanese Patent Publication No. 38-17467.

However, liquid detergents containing dodecyldimethylamine oxide, which has been commonly used as a tertiary amine oxide, are not fully satisfactory in terms of lather palatability and feel on hands, and have poor rinsability after cleaning. The drawback was that it got worse. Furthermore, it can be used as a coactivator for tertiary amine oxides having 50% or more of straight chain alkyl groups having 14 carbon atoms, higher fatty alkanolamides, and secondary alcohol ethoxylates (t-, 1%M alcohol ether sulfate). Can be used together (Unexamined Japanese Patent Publication No. 5
6-112999), and a combination of a tertiary amine oxide with a linear chain ratio of 40 to 70% and a specific alkyl chain distribution and a higher fatty dark alkanolamide as a co-activator for higher alcohol ether sulfate. (Japanese Unexamined Patent Publication No. 141400/1983) was proposed.

However, in either case, the problem of poor rinsing performance after cleaning could not be avoided.

[Means for solving problems]

Under such circumstances, the present inventors conducted intensive research to overcome the above problems and found that anionic surfactants,
By blending a specific dicarboxylic acid surfactant and a terpene hydrocarbon with at least one non-soap synthetic surfactant selected from nonionic surfactants and amphoteric surfactants, excellent The present invention was completed based on the discovery that it is possible to obtain a liquid detergent composition that has good cleaning and foaming power, good rinsing properties after washing, and less roughness on hands.

That is, the present invention uses the following components (A), (B) and 0 (A
) 5 to 60% by weight of at least one non-soap synthetic surfactant selected from anionic surfactants, nonionic surfactants and amphoteric surfactants (B) 0.05 to 5% of dicarboxylic acid surfactants Weight % C) A liquid cleaning composition characterized by containing 0.01 to 3 weight % of a terpene hydrocarbon selected from monoterpenes and sesquiterpenes.

Surfactants that can be used as component (A) in the present invention include the following.

(1) Anionic surfactant (1) Sulfonate-based straight chain or branched alkyl (C+~Cu) benzenesulfonate, straight chain or branched alkyl (Cm~C!) sulfonate, long chain olefin (C8~Co ) Sulfonates, etc. (II) Sulfate-based long chain monoalkyl (C8-Cs5) sulfate ester salts, ?

The counter ions (cations) of the above anionic surfactants, such as acyl (Ca~Co) glutamates and long chain N-acyl (C~Czx) sarcosinates, are alkali metals or alkaline earths such as sodium, potassium, and magnesium. It may be any of similar metal ions and alkanolamine ions such as monoethanolamine, jetanolamine, and triethanolamine.

Each of the surfactants, including the typical examples exemplified above, such as betaine amphoteric surfactants such as betaine alkyl acetates and imidacillin amphoteric surfactants, can also be used alone as the component (g); The above may also be combined to form component (5). The surfactant content ranges from 5 to 60% by weight, preferably from 10 to 401% by weight of the detergent composition. If this amount is less than 5% by weight, the detergency and foaming power of the surfactant will not be sufficient;
On the other hand, if a surfactant is added in an amount exceeding 60% by weight, no particular improvement in detergency can be expected; rather, it may cause foam breakage, deteriorated rinsability, and high viscosity, making it difficult to handle during manufacturing. This is not desirable because it makes it difficult.

The zocarboxylic R-type surfactant as component (B) of the present invention has the following general formula CI)% (Cl)% (Cl) or (E) [wherein R1 is a straight or branched alkyl group or alkenyl having 8 to 16 carbon atoms] represents a group, R3 may have a branched chain, -(C)I, -CH, -(B)n-(CM, ), a group (m
= 1 to 5, n = o to 5), and yen and dove represent hydrogen, alkali metals, alkaline earth metals, or alkanolamines] Any of the compounds represented by these can be used, but the stability of the composition From these points of view, dicarboxylic acid surfactants represented by general formula (1) are particularly preferred.

Φ) component is 0.05 to 5% by weight based on the composition, sometimes 0
．． It is preferably added in a range of 1 to 3%.

If it is outside this range, the desired effect of improving layer color properties and rinsability cannot be expected.

Examples of the zero component used in the present invention include monoterpene hydrocarbons or sesquiterpene hydrocarbons contained in plant aromatic oils. Examples of monoterpene hydrocarbons include D- or L-limone contained in orange oil, lemon oil, etc., α- or I-pinene contained in terpine oil, etc., and sesquiterpene hydrocarbons include Examples include caryophyllene and cedrene, which are abundantly contained in fern oil, clover 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. , Noqin oil can be incorporated into the composition of the present invention as it is. The blending amount of component 0 is 0.01 to 3% by weight of the cleaning composition.
, preferably in the range of 0.1 to 2% by weight. If the amount is less than 0.01% by weight, the desired improvement in rinsability will be insufficient, while if it exceeds 3% by weight, the coloring properties and low-temperature stability of the cleaning composition will deteriorate, which is not preferred.

The pH range of the stock solution of the liquid detergent composition of the present invention is preferably 4 to 9, and more preferably 5 to 8.

Further, other optional components can be added to the cleaning composition of the present invention within a range that does not impair the separation stability, cleaning performance, and foaming performance of the composition. For example, lower aliphatic alcohols such as ethyl alcohol, solubilizers such as sodium salts and potassium salts of toluenesulfonic acid and xylenesulfonic acid, and urea, viscosity aMJ moderating agents such as clay minerals and water-soluble polymer substances, calcite, Silica stone, calcium phosphate, zeolite, polyethylene, nylon, ? Water-insoluble abrasives such as Listerene, humectants such as glycerin and nlubitol,
Feel-enhancing agents such as cationized cellulose, other enzymes, fragrances, pigments, preservatives and antifungal agents, etc. can be added.

The liquid detergent composition of the present invention can be used in laundry detergents, dishwashing detergents, household detergents, hair detergents, human body detergents, etc.
This is a liquid detergent composition of high practical value, which has excellent rinsing properties after cleaning and less roughness on hands, without impairing its original functions, ie, cleaning power and foaming power.
