Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to colored liquid cleaning compositions. More specifically, the present invention relates to a colored round liquid cleaning composition having excellent light resistance and heat resistance.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, products containing nine transparent liquids in transparent containers have recently been put on the market, and their fresh image has been well received by consumers. It is becoming increasingly important. However, the coloring of liquid kitchen cleaners involves several technical difficulties. First, from a safety perspective, the types of coloring additives that are allowed to be used in kitchen liquid detergents are legally limited, but most of them discolor or fade due to heat in light in the presence of surfactants. Crystal clear. In addition, from the commercial value point of view, it is desirable that the color is not a poisonous green color, but if a small amount of coloring additive is added, the color will further change and fade, resulting in islands. Due to this situation, the coloring additives that have been practically used in kitchen detergents have been limited to red and yellow colors. However, when showing various colored liquids to 100 people,
We conducted a survey to find out what people thought about colors when used as kitchen detergents, and as is clear from the results shown in the table below, red-medium-yellow did not necessarily meet consumers' tastes. It is necessary to search for nine kitchen liquid detergents that are colored in consumer preference KtikL nine hues other than red and yellow. As a result of extensive research into food additives other than yellow and various coloring additives approved by J-Technology 8,
If a specific surfactant mixture system is selected for a specific coloring 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. They discovered this and completed the present invention.

That is, the present invention includes (A) high Wk alcohol ether sulfate, alkylbenzene sulfonate, α-olefin sulfonate as essential components.
10 to 40% by weight of one or more anionic surfactants selected from the group consisting of 1 to 10% by weight of higher fatty acid alkanolamide (0) The following general formula (5-class carbon oxide represented by RI 0.2~S weight - R layer R knee summer → 0 (I) 5 (In formula (1), R is a carbon number of 10 to 18 The alkyl group, and R3 each represent a methyl group or an ethyl group.
) and Inodantrene Blue US (Color Index Muro 9800) A liquid cleaning agent colored green containing one or two coloring additives selected from O, 00001 to 0.005% by weight, and Inodantrene Blue US (Color Index Muro 9800). It is coated with an agent composition.

The liquid cleaning composition according to the present invention is colored with a preferable green color by a small amount of coloring additive, does not change color or fade even when placed in a transparent container as a transparent liquid, and has extremely good heat resistance and light resistance. , consumer preference is also very high K11
l, become. Moreover, it has extremely excellent basic performance as a kitchen liquid detergent, such as detergency, roughness prevention properties, and rinsability.

Furthermore, the kitchen liquid cleaning composition according to the present invention is obtained for the first time by combining the above-mentioned specific color additive and a specific surfactant mixture system, and other green color additives. or other surfactant mixtures, it is not possible to satisfy both stable green coloration and basic performance as a kitchen detergent.

The ionic surfactant in the surfactant group 1 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 sluaates are preferred, and those represented by the following general formula (10) are particularly preferred.

It is obtained from one or a mixture of two or more saturated or unsaturated fatty acids and monoethanolamine or jetanolamine, such as coconut fatty acid jetanolamide.

It can be blended within the range of 0.2 to 5 weight! tL. Outside this range, the effect of addition may be reduced and the liquid stability at low temperatures may deteriorate. Organic acids can also be blended, and examples of suitable organic acids include gluconic acid, fluoric acid, lactic acid, gelcolic acid, citric acid, and tartaric acid. However, citric acid and tartaric acid are best salted with an oxidizing agent such as hydrogen peroxide, so that S*, in which trace components in both are oxidized and denatured, is lost. The amount of these organic acids to be sewn is desirably within the range of o.oos to 0.5% by weight. or,
Hydrotropes can also be included. Desirable hydrotropic agents include paratoluene sulfonate, metaxine/sulfonate, cumene sulfonate, etc., and the blending amount thereof is preferably within the range of 0.2 to 5% by weight. In addition to these, fragrances, colorants (but with good stability), antioxidants, amphoteric surfactants in amounts that do not affect the effects of the present invention, nonionic surfactants, ultraviolet absorbers,
Preservatives, extrinsic agents (for example, pearlizing agents), etc. can be added as necessary.
