Description
본 발명은 액체 세정제 조성물에 관한 것으로 , 더욱 상세하게는 자연분해가 가능하고, 중공업분야 특히 철강분야에서 철제품을 가공하는 과정에서 연마시 사용하는 연마유와 먼지 등을 포함하는 오염을 제거하기 위해 사용되는 수용성 세정제 조성물에 관한 것이다.The present invention relates to a liquid detergent composition, and more particularly, it is possible to decompose naturally, and to remove contamination including abrasive oil and dust used during polishing in the processing of iron products in heavy industry, especially steel. It relates to a water-soluble detergent composition used.
종래의 세정제는 주로 디클로로메탄(Dichloromethane) 또는 퍼클로로 에틸렌(Perchloroethylene)등과 같이 세정력은 뛰어나지만 환경규제의 대상이 되는유기용제를 주로 포함고 있다. 이와 같은 유기용제는 주로 환경규제의 대상이 되는 VOC(Volatile Organic Compound, 휘발성 유기 화합물)들이 많아 대기오염, 광화학 반응을 통한 스모그의 형성, 도시 오존농도의 상승등의 원인이 되고 있다.Conventional cleaners mainly include organic solvents that are subject to environmental regulation, although they have excellent cleaning power, such as dichloromethane or perchloroethylene. Such organic solvents are mainly VOCs (Volatile Organic Compounds) that are subject to environmental regulations, causing air pollution, the formation of smog through photochemical reactions, and the increase of urban ozone concentration.
또한 종래의 세정제에는 인산류와 옥틸페놀이 포함되어 있어 부영양화를 일으키며, 또한 페놀유도체로 인한 인체 유해 요소를 포함하고 있다.In addition, the conventional cleaning agent contains phosphoric acid and octyl phenol, causing eutrophication, and also contains human harmful elements caused by phenol derivatives.
더구나 기존의 세정제는 자연분해가 되지 않거나 자연분해가 되더라도 분해속도가 아주 느려서 수질의 오염을 야기하고 있다.In addition, conventional detergents are not decomposed naturally or even if decomposed very slowly, causing water pollution.
이에 본 발명자들은 상기와 같은 문제점을 해결하기 위해 수많은 연구와 실험을 행한 결과, 환경규제의 대상이 되는 VOC(Volatile Organic Compound, 휘발성 유기 화합물)를 포함하지 않고, 세정력도 우수하며 자연분해가 가능한 액체 수용성 세정제를 개발하였다.Accordingly, the present inventors have conducted numerous studies and experiments to solve the above problems, and as a result, they do not include VOC (Volatile Organic Compound) which is the subject of environmental regulation, and have excellent cleaning power and are naturally degradable. A water soluble cleaner was developed.
도 1은 본 발명에 의한 액체 세정제 조성물의 세정도 실험 결과를 나타낸 막대그래프이다.1 is a bar graph showing the results of the degree of cleansing experiment of the liquid detergent composition according to the present invention.
도 2는 본 발명에 의한 액체 세정제 조성물과 기존 세정제의 세정도를 비교한 실험 결과를 나타낸 막대그래프이다.Figure 2 is a bar graph showing the results of the experiment comparing the cleaning degree of the liquid detergent composition and the conventional detergent according to the present invention.
본 발명은 팜유 5 내지 10 중량%, 트리에탄올아민 3 내지 10 중량%, 알킬폴리옥시에틸렌 에테르와 직쇄형 알킬벤젠설폰산염의 일종 이상을 7 내지 15 중량%, 시트르산 2 내지 4 중량%, 시트르산 나트륨 2 내지 5 중량%, 폴리규산나트륨 2 내지 3 중량%, 황산나트륨 1 내지 3 중량% 및 잔여량의 물로 구성되는 것을 특징으로 하는 수용성 세제 조성물에 관한 것이다.The present invention is 5 to 10% by weight of palm oil, 3 to 10% by weight of triethanolamine, 7 to 15% by weight of at least one kind of alkyl polyoxyethylene ether and linear alkylbenzenesulfonate, 2 to 4% by weight citric acid, sodium citrate 2 To 5% by weight, 2-3% by weight of sodium polysilicate, 1-3% by weight of sodium sulfate and a residual amount of water.
본 발명의 세정제 조성물에는 자연분해가 가능한 식물성 유지인 팜유를 5 내지10 중량% 사용한다. 팜유를 10 중량% 이상으로 사용하면 세정기능이 떨어지고 탁도가 증가하며, 5 중량% 이하로 사용하면 트리에탄올아민과 반응하여 생성되는 염기성 에스테르의 계면활성제의 양이 적게 생성된다.In the detergent composition of the present invention, palm oil, which is a vegetable oil that can be decomposed naturally, is used in an amount of 5 to 10% by weight. When palm oil is used in an amount of 10% by weight or more, the washing function is reduced and turbidity is increased. When palm oil is used in an amount of 5% by weight or less, the amount of surfactant of the basic ester produced by reaction with triethanolamine is generated.
트리에탄올아민{N[(CH2CH2O)xH]3}은 약염기성이며 물과 매우 잘 혼합되는 점성이 큰 비휘발성물질로서 본 발명에서는 3 내지 10 중량%를 사용한다. 트리에탄올아민을 3 중량% 이하로 사용하면 세정도가 저하되고, 10 중량% 이상을 사용하면 세정도에는 영향이 없으나 질소화합물의 양이 증가하게 되므로 필요 이상 많이 사용하는 것은 비경제적이다.Triethanolamine {N [(CH 2 CH 2 O) x H] 3 } is a weakly basic, highly viscous non-volatile material that is very well mixed with water, and 3 to 10% by weight is used in the present invention. If the triethanolamine is used in an amount of 3% by weight or less, the detergency is lowered. If 10% by weight or more is used, the detergency is not affected, but the amount of the nitrogen compound is increased.
식물성 유지인 상기한 팜유와 독성이 적은 비휘발성 물질로 공지되어 있는 (참고문헌: Inoue등(1982) Mutat.Res., Mortelmans등(1986) Environ.Mutagen, Yoon등(1982) Environ.Mutagen, Hoshino등(1982) Can.Res., Galloway등(1987) Environ.MoLMutagen 등) 상기한 트리에탄올아민을 산촉매하에 반응시키면 모노알킬 에스테르, 디알킬 에스테르, 트리알킬 에스테르가 생성되어 염기성 에스테르의 계면활성제가 된다. 상기 반응에서 사용되는 산촉매는 톨루엔설폰산을 사용한다.Palm oil, a vegetable oil, is known as a non-toxic substance with low toxicity (Ref. Inoue et al. (1982) Mutat. Res., Mortelmans et al. (1986) Environ. Mutagen, Yoon et al. (1982) Environ. (1982) Can. Res., Galloway et al. (1987) Environ. Molmutagen et al.) The reaction of the above-described triethanolamine under an acid catalyst produces a monoalkyl ester, a dialkyl ester, a trialkyl ester, and becomes a surfactant of the basic ester. As the acid catalyst used in the reaction, toluenesulfonic acid is used.
이에 대한 반응식은 다음과 같다.The reaction scheme is as follows.
RCO2R′+ N[(CH2CH2O)XH]3→ N{[(CH2CH2O)XH]2(CH2CH2O)XCOR} +RCO 2 R ′ + N [(CH 2 CH 2 O) X H] 3 → N {[(CH 2 CH 2 O) X H] 2 (CH 2 CH 2 O) X COR} +
N{[(CH2CH2O)XH](CH2CH2O)XCOR}2+ N[(CH2CH2O)XCOR]3 N {[(CH 2 CH 2 O) X H] (CH 2 CH 2 O) X COR} 2 + N [(CH 2 CH 2 O) X COR] 3
(x= 1 내지 12)(x = 1 to 12)
상기한 반응에서 생성된 염기성 에스테르의 계면활성제는 세정작용뿐만 아니라 전자공여체인 질소를 포함하고 있으므로 항산화작용도 겸비된다.Since the surfactant of the basic ester produced | generated by said reaction contains nitrogen which is an electron donor as well as a washing | cleaning action, it also has antioxidant activity.
또한 천연유지인 팜유와 독성이 적은 트리에탄올아민을 반응시켜 생성된 것이므로 독성이 거의 없고 자연분해가 가능하여 환경친화적이다. 그러므로 철강제품의 세정제 이외에 주방용 세정제로도 사용될 수 있다.In addition, since it is produced by reacting palm oil, which is a natural fat, with triethanolamine, which is less toxic, there is little toxicity and it is environmentally friendly because it can be naturally decomposed. Therefore, it can be used as a kitchen cleaner in addition to the steel product cleaner.
