Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a novel aromatic liquid detergent composition, and more particularly, to a novel aromatic liquid detergent composition, which has excellent detergency and good storage stability, and which is suitable for use as a product. This invention relates to a zeolite-containing aromatic liquid detergent composition for clothing, which not only has a good fragrance, but also leaves a good fragrance during washing, and can impart an excellent residual fragrance to items to be washed, such as clothing, after washing. be.

BACKGROUND OF THE INVENTION In recent years, liquid detergents have been increasingly used as detergents for clothing due to their ease of measurement and space saving. This liquid detergent usually has a composition in which the ingredients are uniformly dissolved from the viewpoint of storage stability, and does not contain water-insoluble zeolite, which is used in granular detergents to improve detergency. Not yet.

Therefore, liquid detergents that do not contain zeolite tend to have lower detergency than granular detergents that contain zeolite, and various attempts have been made to improve their detergency. There is. For example, attempts have been made to utilize soluble calcium-trapping compounds such as sodium citrate and polycarboxylic acids (Japanese Unexamined Patent Publication No. 56-127
696, 60-106892), it has also been proposed to mix a large amount of electrolyte to salt out the surfactant, form a suspension with a rough three-dimensional structure, and increase the amount of builder blended. (Japanese Unexamined Patent Publication No. 145794/1983). However, although these methods improve the cleaning power to some extent, it is still not sufficient.

Therefore, progress is being made in the development of a liquid detergent for clothing that has good storage stability and excellent detergency, in which zeolite is homogeneously dispersed using a polymeric thickener.

However, in liquid detergents in which zeolite is suspended, if fragrances are used in liquid detergents, which are normally used to impart scents to the product or to impart a residual fragrance to washed clothes, etc. Due to the adsorption effect of zeolite, problems arise such as fragrances being trapped in products, making it difficult to emit fragrances during washing, and making it difficult to leave a lingering fragrance on clothes after washing.

Problems to be Solved by the Invention Under these circumstances, the present invention provides a product that has good detergency and storage stability, and has a good fragrance when made into a product.
The purpose of this invention is to provide an aromatic liquid detergent composition that leaves a good fragrance even during washing and can impart an excellent residual fragrance to items to be washed, such as clothes, after washing.

Means for Solving the Problems The present inventors have conducted intensive research to develop a zeolite-containing liquid detergent composition having the above-mentioned preferable properties. Based on this knowledge, they discovered that the objective could be achieved by including a fragrance having a specific molecular weight and a specific boiling point in a composition in a predetermined ratio. Based on this, the present invention has been completed.

That is, the present invention uses 5 to 50% by weight of a surfactant, 1 to 30% by weight of a zeolite builder, and 0.3 to 0.3% by weight of a polymer thickener.
Perfume mixture containing 5% by weight or more of a perfume component with a molecular weight of 220 or more and 7% by weight or more of a perfume component with a boiling point of 240'O or less based on the total perfume, relative to a liquid detergent base containing 20% by weight. The present invention provides an aromatic liquid detergent composition containing 5% by weight.

The present invention will be explained in detail below.

There are no particular restrictions on the surfactant used as part of the detergent base of the composition of the present invention, and any surfactant may be selected from those commonly used in conventional liquid detergents for clothing. can. Examples of such substances include linear alkylbenzene sulfonates having an alkyl group having 8 to 16 carbon atoms, alkyl sulfates having 10 to 20 carbon atoms, olefin sulfonates having 10 to 20 carbon atoms, and olefin sulfonates having 10 to 20 carbon atoms. 20 alkanesulfonate, carbon & 10~2
Anionic surfactants such as sulfates of alkyl ethers or alkenyl ethers having 0 linear or branched alkyl or alkenyl groups and added with an average of 0.5 to 8 moles of ethylene oxide, and carbon atoms of 8 ~18 primary or secondary alcohols with ethylene oxide (EO)
The surfactant is an EO-added nonionic surfactant containing an average of 7 to 18 moles of
It is blended in an amount of 15 to 30% by weight, preferably 15 to 30% by weight. If the amount is less than 5% by weight, sufficient cleaning power cannot be obtained;
If it exceeds 0% by weight, the liquid properties will become unstable.

Zeolites used as builders are generally x(M,
O or IJ'O) ・k(hos ・y(SiOz)
@z(HzO)''・(I) (In the formula, M is an alkali metal atom, M' is an alkaline earth metal atom exchangeable with calcium, xS'i and 2 are the number of moles of each component, - For boat fishing, X is 0.7~5, y is 1~3.
Crystalline or amorphous aluminosilicates represented by 2 (2 is an arbitrary number), or mixtures thereof are suitable.

The average particle diameter of this zeolite is desirably 5 μm or less, preferably 2 μm or less, from the viewpoint of detergency and dispersion stability, and the amount thereof is 1 to 30% by weight based on the total amount of the composition. It is preferably selected in a range of 5 to 25% by weight. If the amount is less than 1% by weight, sufficient detergency cannot be obtained, and if it exceeds 30% by weight, the viscosity of the composition increases, which is not preferable.

In addition, the polymer thickener used in combination with the surfactant and zeolite-based virgoo is for stably dispersing the zeolite, and is particularly suitable as long as it can be uniformly dissolved in the above-mentioned concentrated surfactant aqueous solution system. Although not limited, preferred examples include acrylic ester/methacrylic ester copolymer, methacrylic acid/acrylic ester copolymer or salt thereof, cationized cellulose, polystyrene sulfonate, polycarboxylate, methyl vinyl ether/ Examples include maleic anhydride monobutyl ester copolymer. One type of these polymer thickeners may be used, or two types may be used.
You may use combinations of more than one species.

The blending amount is 0.3 to 20% by weight based on the total amount of the composition,
It is preferably selected within the range of 0.5 to 10% by weight. If this amount is less than 0.3% by weight, a sufficient dispersion stabilizing effect will not be exhibited, and if it exceeds 20% by weight, no improvement in the effect will be recognized for the amount.

In the composition of the present invention, the fragrance mixture blended to impart aromatic properties contains 5% by weight or more of a fragrance with a molecular weight of 220 or more and 7% by weight or more of a fragrance with a boiling point of 240° C. or less, based on the total fragrance. However, it is also possible to include fragrances with a molecular weight of less than 220 or fragrances with a boiling point of more than 240'O. Also, if desired,
Non-aromatic organic compounds such as solvents and extenders having molecular weights up to about 400 can also be included.

Normally, low-molecular-weight fragrances make up the fragrance, but if the molecular weight is small, the adsorption ability of zeolite will make the fragrance extremely weak in the product. Therefore, when a fragrance with a molecular weight of 220 or more is used, it is difficult to be adsorbed to zeolite, and therefore, when made into a product, it has a strong fragrance. However, this fragrance with a large molecular weight is difficult to evaporate, so it is difficult to leave a scent during washing. On the other hand, low boiling point fragrances with a boiling point of 240°C or less are well adsorbed by zeolite, but are easily desorbed by water during washing. Moreover, a residual fragrance is effectively imparted to clothes etc. after washing.

If the content of the fragrance with a molecular weight of 220 or more in the fragrance mixture is less than 5% by weight, the fragrance will be insufficient when used as a product, and the content of the fragrance with a boiling point of 240°C or less is 7% by weight.
If it is less than that, the fragrance during washing will not be sufficient.

Further, in the composition of the present invention, the content of the fragrance mixture is selected in the range of 0.05 to 5% by weight based on the total amount of the composition. If this amount is less than 5% by weight of O,OS, the effect of the present invention will not be fully exhibited, and it is not necessary to contain more than 5% by weight.In fact, if it exceeds 5% by weight, the odor of the product will be reduced during cleaning. This is not preferable because the scent of the product or the residual scent of the items to be cleaned is too strong and is economically disadvantageous.
