Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to colored liquid cleaning compositions.

More specifically, the present invention relates to a colored liquid cleaning composition having excellent light resistance and heat resistance of 20. In liquid cleaning agents,
The hue is an important component of the product because it greatly affects the consumer's image of the product. Regarding kitchen liquid detergents, transparent liquid products packaged in transparent containers have recently become commercially available, and their fresh images have been well received by consumers. It is becoming increasingly important. However, the coloring of liquid kitchen cleaners involves some technical difficulties. First, from a safety perspective, the types of coloring additives that are permitted to be used in kitchen liquid detergents are legally limited, but most of them discolor or discolor due to light or heat in the presence of surfactants. Easy to fade. In addition, from the commercial value point of view, it is desirable that the color is not poisonous, but if the amount of coloring additive is kept small, the color will change and fade even more easily. Due to this situation, the coloring additives that have conventionally been used in kitchen detergents have been limited to red and yellow color additives. However, when we showed 100 housewives various coloring liquids and asked them how they thought about colors when using them as kitchen detergents, it was clear from the results shown in the table below that red and yellow were consumed. Therefore, it is necessary to search for liquid kitchen cleaners colored in hues other than red and yellow that match consumer preferences. The inventors believed that the cause of discoloration and fading was due to the surfactant system, and as a result of intensive research on various coloring additives approved by JIS and food additives other than red and yellow, we found that We discovered that if a specific surfactant mixture system is selected as an additive, a green-colored liquid cleaning composition with excellent light resistance and heat resistance can be obtained even with a small amount of coloring additive. The present invention has now been completed.

That is, in the present invention, as an essential component, (A) one or more anionic surfactants selected from the group consisting of higher alcohol ether sulfates, alkylbenzene sulfonates, α-olefin sulfonates, and alkanesulfonates (10 to 40); weight%,
(1-10% by weight of higher fatty acid alkanolamide,
(00.2 to 5% by weight of tertiary amine oxide represented by the following general formula (1) (in formula (1), R1 has 10 carbon atoms)
(9) Green No. 3 (Color Index Boiled 42053) and Indan Tremble RS
This is a green-colored liquid cleaning composition characterized by containing 0.000001 to 0.005% by weight of one or two coloring additives selected from (Color Index Boiled 69800).

The liquid cleaning composition according to the present invention is colored in a preferable green color by a small amount of coloring additive, does not discolor or fade even when placed in a transparent container as a transparent liquid, and has extremely good heat resistance and light resistance. Therefore, consumer preference will be very high.

Moreover, it has extremely excellent basic performance as a kitchen liquid detergent, such as detergency, roughness prevention properties, and rinsability.
Further, the kitchen liquid cleaning composition according to the present invention is obtained only by combining the above-mentioned specific coloring additive and a specific surfactant mixture system, and it is obtained by combining the above-mentioned specific coloring additive and specific surfactant mixture system, and does not contain any other green coloring additive or However, other surfactant mixture systems cannot satisfy both the stable green coloring and the basic performance as a kitchen detergent. The anionic surfactant in the surfactant mixture system used in the present invention is selected from higher alcohol ether sulfates, alkylbenzene sulfonates, α-olefin sulfonates, and alkanesulfonates, and among these, higher alcohols are selected from the viewpoint of skin mildness. Ether sulfates are preferred, and those represented by the following general formula (river) are particularly preferred.

R4O(CH2CH2O)NSO3M() (in the formula, R4
is a hydrocarbon group having 10 to 18 carbon atoms, and n is 1 on average.
The number ˜6, M is an alkali metal, ammonium or alkanolamine.

) Also, higher fatty acid alkanolamide has 10 to 1 carbon atoms.
It is obtained from one type or a mixture of two or more types of saturated or unsaturated fatty acids (8) and monoethanolamine or diethanolamine, such as coconut fatty acid diethanolamide. Furthermore, the tertiary amine oxide is selected from the compounds represented by the general formula (1).

The blending ratio of these essential components in the colored liquid cleaning composition is 10 to 40% by weight of anionic surfactant;
1 to 10% by weight of higher fatty acid alkanolamide, 0.2 to 5% by weight of tertiary amine oxide, and 0.000001 of one or two coloring additives selected from Green No. 3 and Indan Tremble-RS. ~0.005% by weight.

The cleaning agent according to the present invention can contain an inorganic electrolyte or a solvent (ethanol, glycerin, etc.), but preferable inorganic electrolytes include MgCl2, MgSO4, Na2s, etc.
There are O4 and Na2cO3, and it is desirable to blend them in a range of 0.2 to 5% by weight. Outside this range, the effect of addition may be reduced or the liquid stability at low temperatures may deteriorate.
Organic acids can also be blended, and preferred organic acids include gluconic acid, malic acid, lactic acid, glycolic acid, citric acid, and tartaric acid. However, citric acid and tartaric acid should be treated with an oxidizing agent such as hydrogen peroxide.
The degree of oxidation is preferably such that trace components in both are oxidized and denatured. The blending amount of these organic acids is preferably within the range of 0.005 to 0.5% by weight. Moreover, a hydrolobe agent can also be blended. Desirable hydrodrobe agents include paratoluene sulfonate, metaxylene sulfonate, cumene sulfonate, etc., and the blending amount thereof is 0.
．． It is preferably within the range of 2 to 5% by weight. In addition to these, fragrances, colorants (but with good stability), antioxidants, amphoteric surfactants, nonionic surfactants, ultraviolet absorbers, and preservatives in amounts that do not impair the effects of the present invention. , an appearance changing agent (for example, a pearlizing agent), etc. can be added as necessary.
