Description

本発明は、油汚れに対して優れた洗浄力を有する、硬質表面用として好適な液体洗浄剤組成物に関する。   The present invention relates to a liquid detergent composition suitable for hard surfaces, which has excellent detergency against oil stains.

一般に洗浄剤は、浴室、台所、床等の処理対象の異なる汚れを除去するため、それぞれに適した組成のものが用いられている。例えば、レンジ、オーブン、レンジまわりの壁や床、換気扇といった台所まわりに用いられる台所まわり用洗浄剤としては、熱、日光、空気中の酸素等の作用により変質した油汚れを除去するため、界面活性剤、溶剤及びアルカリ剤等を含む洗浄剤が用いられている。また、浴槽、浴室の壁及び床といった浴室に用いられる浴室用洗浄剤としては、金属石鹸、特に脂肪酸のカルシウム塩の汚れを除去するため、界面活性剤、溶剤、金属イオン封鎖剤等を含む洗浄剤が用いられている。かかる洗浄剤は、高い洗浄性能を発揮するためpH10以上のアルカリ性に調整される場合が多い。   In general, cleaning agents having a composition suitable for each of them are used in order to remove different stains to be treated, such as bathrooms, kitchens, and floors. For example, kitchen cleaners used around kitchens such as ovens, ovens, walls and floors around the range, and exhaust fans are used to remove oil stains that have been altered by the action of heat, sunlight, oxygen in the air, etc. A cleaning agent containing an activator, a solvent, an alkali agent and the like is used. Also, as bathroom cleaners used in bathrooms such as bathtubs, bathroom walls and floors, metal soaps, especially detergents containing detergents, metal ion sequestering agents, etc., are used to remove dirt from fatty acid calcium salts. The agent is used. Such detergents are often adjusted to be alkaline with a pH of 10 or higher in order to exhibit high cleaning performance.

また、液体洗浄剤の魅力の一つとして洗浄剤の液色が挙げられる。洗浄剤の液色は無色であっても洗浄性能には影響を及ぼさないが、液色があることによって消費者に対する印象を向上させることができる。ところが、pH10以上のアルカリ性条件下において、熱や光等の影響を受けても長期間退色しない色素は少なく、特に鮮明かつ長期間の保存安定性に優れた緑色に着色することは非常に困難であった。特許文献1や特許文献2に記載されているように、水不溶性の顔料を顔料分散剤を用いて分散させる着色方法が従来より知られているが、この方法では高価な顔料分散剤を必要とするため配合コストが高くなるという欠点がある。また、顔料を用いる場合には組成物の凍結と融解が繰り返されることで顔料が沈殿し、美観が損なわれる場合がある。   Moreover, the liquid color of a cleaning agent is mentioned as one of the charms of a liquid cleaning agent. Even if the liquid color of the cleaning agent is colorless, it does not affect the cleaning performance, but the presence of the liquid color can improve the consumer's impression. However, under alkaline conditions of pH 10 or higher, there are few pigments that do not fade for a long time even under the influence of heat, light, etc., and it is very difficult to color green that is particularly clear and excellent in long-term storage stability. there were. As described in Patent Document 1 and Patent Document 2, a coloring method in which a water-insoluble pigment is dispersed using a pigment dispersant has been conventionally known. However, this method requires an expensive pigment dispersant. Therefore, there is a disadvantage that the blending cost becomes high. In the case of using a pigment, the pigment may precipitate due to repeated freezing and thawing of the composition, which may impair the aesthetic appearance.

そこで本発明は、鮮明な緑色に着色されており、かつ各種汚れ、特に変性油汚れに対して高い洗浄力を発揮できるアルカリ性の液体洗浄剤組成物を提供することを課題とする。   Accordingly, an object of the present invention is to provide an alkaline liquid detergent composition that is colored in a clear green color and that can exhibit high detergency against various types of dirt, particularly modified oil dirt.

本発明者らが鋭意検討した結果、洗浄性能を発揮するために最低限必要となる、アミンオキサイド類とアルカリ剤の組み合わせに対し、銅フタロシアニン系青色色素とアゾ系黄色染料を添加することで鮮明な緑色が得られることを見出した。また、銅フタロシアニン系青色色素を用いた場合には色素の沈殿が起こらず、緑色の外観が長時間にわたる高温保存や紫外線照射を行っても目視では変化が見られないことを確認し、本発明を完成した。   As a result of intensive studies by the present inventors, it is clear that a copper phthalocyanine blue dye and an azo yellow dye are added to the combination of amine oxides and an alkali agent, which is the minimum necessary for exhibiting cleaning performance. Found that a green color could be obtained. In addition, when copper phthalocyanine-based blue pigment is used, pigment precipitation does not occur, and it is confirmed that the green appearance does not change visually even after high-temperature storage or ultraviolet irradiation over a long period of time. Was completed.

即ち本発明は、

(b)アルカリ剤 0.01〜30質量%、
(c)銅フタロシアニン系青色色素、

本発明の液体洗浄剤組成物は、油汚れ洗浄力に優れ、鮮明な緑色の外観を有しているだけでなく、液性がアルカリ性であるにもかかわらず、熱や光等の影響を受けても長期間退色しない。このため、製品の美観が長期間にわたって損なわれないという効果を有している。本発明の液体洗浄剤組成物は、特に台所まわり用洗浄剤として適している。   The liquid detergent composition of the present invention is not only excellent in oil stain cleaning power, has a clear green appearance, but is also affected by heat, light, etc., even though the liquid property is alkaline. But it won't fade for a long time. For this reason, it has the effect that the aesthetics of a product are not impaired over a long period of time. The liquid detergent composition of the present invention is particularly suitable as a kitchen detergent.

本発明で用いる(a)成分のアミンオキサイド類は、洗浄力のみならず、染料の色相安定性にも効果がある。アミンオキサイド類としては、例えば炭素数1〜24の直鎖又は分岐鎖アルキル基又はアルケニル基を有するアルキル又はアルケニルアミンオキサイドを挙げることができる。より好ましいアミンオキサイドとしては、下記の一般式(I)で表されるアルキルアミンオキサイドを挙げることができる。   The amine oxides (a) used in the present invention are effective not only in detergency but also in dye hue stability.

C 32 H (16-n) X n N 8 Cu (VI)
(In the formula, n is an average number of 0 to 10, and X is a halogen atom)

一般式(VI)中、Xで示されるハロゲン原子としては、塩素原子、臭素原子、ヨウ素原子等が挙げられ、その中でも塩素原子が好ましい。銅フタロシアニン系青色顔料は、骨格中の塩素付加数の増加に伴って色相が青色から緑色に変化する傾向にある。例えば、緑色顔料である平均塩素付加数が14個であるPigment Green 7は、アルカリ洗浄剤中での長期分散安定性が十分ではない。この理由は、塩素付加数が多いと銅フタロシアニン自体の水分散性を低下させるか、もしくは粒子同士の合一傾向が大きくなるためと考えられる。また塩素原子により化合物の比重が増加することもその理由として推測することができる。従って青色色素としての銅フタロシアニン系顔料において、塩素基の付加数は少ない方が好ましく、本発明では1つの化合物に対する平均塩素付加数〔式(VI)中のn〕は0〜10個のものが使用され、更には0〜5個、特には0〜1個が好ましい。具体的な銅フタロシアニン系青色顔料としては、Color Index(C.I.)nameで表記するとPigment Blue 15〔式(VI)中のn=0〕、Pigment Blue 15:1〔式(VI)中のn=0〕、Pigment Blue 15:2〔式(VI)中のn=0〕、Pigment Blue 15:3〔式(VI)中のn=0〕、Pigment Blue 15:4〔式(VI)中のn=0〕、Pigment Blue 76〔式(VI)中のn=10〕等の色素、またこれ以外にもCAS−RNで12239−87−1〔式(VI)中のn=1〕、147−13−7〔式(VI)中のn=1〕、15975−60−7〔式(VI)中のn=1〕、35254−77−4〔式(VI)中のn=2〕、29719−96−8〔式(VI)中のn=3〕、27614−71−7〔式(VI)中のn=4〕、16040−69−0〔式(VI)中のn=4〕、62726−15−2〔式(VI)中のn=5〕、85650−74−4〔式(VI)中のn=6〕、85665−46−9〔式(VI)中のn=7〕として登録されている化合物が挙げられる。これら化合物のうち好ましいものは、平均塩素付加数nが0〜1の化合物であるPigment Blue 15、Pigment Blue 15:1、Pigment Blue 15:2、Pigment Blue 15:3、Pigment Blue 15:4であり、特に好ましいものはPigment Blue 15:3およびPigment Blue 15:4から選ばれる顔料である。   In the general formula (VI), examples of the halogen atom represented by X include a chlorine atom, a bromine atom, and an iodine atom, and among them, a chlorine atom is preferable. Copper phthalocyanine-based blue pigments tend to change in hue from blue to green as the number of added chlorine in the skeleton increases. For example, Pigment Green 7 having an average chlorine addition number of 14 as a green pigment does not have sufficient long-term dispersion stability in an alkaline detergent. The reason for this is considered that when the number of added chlorine is large, the water dispersibility of the copper phthalocyanine itself is lowered, or the coalescence tendency of the particles increases. It can also be assumed that the specific gravity of the compound increases due to chlorine atoms. Therefore, in the copper phthalocyanine pigment as a blue pigment, it is preferable that the number of added chlorine groups is smaller. In the present invention, the average number of added chlorine [n in the formula (VI)] for one compound is 0-10. More preferably 0 to 5, particularly 0 to 1. Specific examples of the copper phthalocyanine-based blue pigment include Pigment Blue 15 [n = 0 in Formula (VI)] and Pigment Blue 15: 1 [Formula (VI) in Color Index (CI) name). n = 0], Pigment Blue 15: 2 [n = 0 in formula (VI)], Pigment Blue 15: 3 [n = 0 in formula (VI)], Pigment Blue 15: 4 [in formula (VI) N = 0], Pigment Blue 76 [n = 10 in the formula (VI)] and the like, and in addition, CAS-RN 12239-87-1 [n = 1 in the formula (VI)], 147-13-7 [n = 1 in formula (VI)], 15975-60-7 [n = 1 in formula (VI)], 35254-77-4 [n = 2 in formula (VI)] 29719-96-8 [in the formula (VI) n = 3], 27614-71-7 [n = 4 in formula (VI)], 16040-69-0 [n = 4 in formula (VI)], 62726-15-2 [in formula (VI) N = 5], 85650-74-4 [n = 6 in formula (VI)], 85665-46-9 [n = 7 in formula (VI)]. Among these compounds, Pigment Blue 15, Pigment Blue 15: 1, Pigment Blue 15: 2, Pigment Blue 15: 3, and Pigment Blue 15: 4 are compounds having an average chlorine addition number n of 0 to 1. Particularly preferred are pigments selected from Pigment Blue 15: 3 and Pigment Blue 15: 4.
