Description

【0001】
【発明の属する技術分野】
本発明は洗浄剤組成物に関し、さらに詳しくは特定の脂肪酸組成を有する脂肪酸モノエタノールアミドを含むことを特徴とする増粘性、起泡性、洗浄力および低温安定性に優れた洗浄剤組成物に関するものである。
【0002】
【従来の技術】
従来、シャンプーや台所洗剤などの主成分として、直鎖アルキルベンゼンスルホン酸塩、アルキルサルフェートやアルキルエーテルサルフェートなどの界面活性剤が用いられており、更にこれらの主成分を補助する目的で脂肪酸モノエタノールアミドが広く用いられている。
【0004】
上記脂肪酸モノエタノールアミドを構成する脂肪酸としては、天然のヤシ油から得られるヤシ油脂肪酸が最も多く用いられている。ところが、ヤシ油脂肪酸モノエタノールアミドは、起泡性、洗浄力、低温安定性には優れているが、かならずしも増粘性が十分でなく、希望する粘度を有する製品を得るのが難しい場合がある。そこで、当業者間では、炭素数が12,14,16,18を主留とする脂肪酸を得て、これらの分別脂肪酸からのモノエタノールアミドを利用するなどしているが、前記の全ての条件を満たすことはできない。
【0005】
すなわち、炭素数12の脂肪酸を主留とする脂肪酸モノエタノールアミドは、起泡力、洗浄力に優れているが低温安定性が十分でない。一方、炭素数14以上の脂肪酸を主留とする脂肪酸モノエタノールアミドは、増粘性は強いが、起泡力、洗浄力、低温安定性が悪くなる。
【0006】
【発明が解決しようとする課題】
本発明の目的は、増粘性、起泡性、洗浄力、低温安定性の優れた脂肪酸モノエタノールアミドを含有する剤形が液状、ペースト状の洗浄剤組成物を提供することである。
【0007】
【課題を解決するための手段】
上記課題を解決するため、本発明者等が鋭意検討の結果、ある特定範囲の脂肪酸組成を有する脂肪酸モノエタノールアミドのみが上記課題解決に有効であることを見い出し本発明を解決するに至った。
【0008】
すなわち、本発明は脂肪酸モノエタノールアミドを構成する脂肪酸として
炭素数12未満の飽和脂肪酸:15%以下
炭素数12の飽和脂肪酸 :45〜55%
炭素数14の飽和脂肪酸 :12〜17%
炭素数18の不飽和脂肪酸
(不飽和数:1) :12〜17%
(ただし、パーム核脂肪酸は除く)
の組成を有する脂肪酸モノエタノールアミドを含有することを特徴とする剤形が液状、ペースト状の洗浄剤組成物である。
【0009】
【発明の実施の形態】
本発明における脂肪酸モノエタノールアミドの脂肪酸組成は、上記割合の混合脂肪酸系のものを用いることが好ましく、この割合を外れると以下のような不都合が生じる。
すなわち、
炭素数12未満の脂肪酸が15%を超えると増粘性が悪くなる。
炭素数12の脂肪酸が45%未満では増粘性が劣り、55%を超えると低温安定性が低下してしまう。
炭素数14の飽和脂肪酸が12%未満では増粘性が劣り、17%を超えると低温安定性が悪くなる。
炭素数18の不飽和脂肪酸が12%未満では増粘性が劣り、17%以上では低温安定性が悪くなる。
【0010】
本発明に用いられる脂肪酸モノエタノールアミドを製造するには油や脂肪酸からの直接反応法、あるいは脂肪酸の低級アルコールエステル法等、どのような方法でも良い。
脂肪酸の調製は、単一組成の脂肪酸を本発明の範囲に混合してもよく、また天然の油を用いてこの範囲内にしてもよい。また、脂肪酸とモノエタノールアミンの反応モル比は、1:1または1:2のいずれでもよい。
本発明の洗浄剤組成物には、その目的によりどのようなアニオン界面活性剤、ノニオン界面活性剤、両性界面活性剤を用いることが出来る。
また、必要に応じて、エタノール、尿素、多価アルコール類、エデト酸等のキレート剤、クエン酸等のpH調整剤、香料、着色剤、アラントイン、グリチルリチン酸等の抗炎症剤、殺菌剤、防腐剤等を用いることが出来る。
本発明の洗浄剤組成物の剤型は液体又は、ペースト状の形状に用いることが出来る。

本発明によって提供される特定の脂肪酸組成を持つ脂肪酸モノエタノールアミドを用いることにより、増粘性、起泡力、洗浄力、低温安定性のいずれにも優れた剤形が液状、ペースト状の洗浄剤組成物を得ることが出来る。[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a detergent composition, and more particularly to a detergent composition excellent in viscosity increase, foamability, detergency and low-temperature stability, characterized by containing fatty acid monoethanolamide having a specific fatty acid composition. Is.
[0002]
[Prior art]
Conventionally, surfactants such as linear alkylbenzene sulfonates, alkyl sulfates and alkyl ether sulfates have been used as the main components of shampoos and kitchen detergents, and fatty acid monoethanolamides for the purpose of assisting these main components. Is widely used.
[0004]
As the fatty acid constituting the fatty acid monoethanolamide, coconut oil fatty acid obtained from natural coconut oil is most frequently used. However, coconut oil fatty acid monoethanolamide is excellent in foamability, detergency, and low-temperature stability, but it is not always thick enough and it may be difficult to obtain a product having a desired viscosity. Therefore, among those skilled in the art, fatty acids mainly having 12, 14, 16, 18 carbon atoms are obtained, and monoethanolamides from these fractionated fatty acids are used. Cannot be satisfied.
[0005]
That is, fatty acid monoethanolamide having a C12 fatty acid as a main fraction is excellent in foaming power and detergency, but is not sufficiently stable at low temperatures. On the other hand, fatty acid monoethanolamide containing a fatty acid having 14 or more carbon atoms as a main fraction is strong in viscosity, but has poor foaming power, detergency, and low-temperature stability.
[0006]
[Problems to be solved by the invention]
An object of the present invention is to provide a detergent composition in which the dosage form containing fatty acid monoethanolamide having excellent viscosity increase, foamability, detergency, and low-temperature stability is liquid and pasty .
[0007]
[Means for Solving the Problems]
As a result of intensive studies by the present inventors in order to solve the above-mentioned problems, the present inventors have found that only fatty acid monoethanolamides having a certain range of fatty acid composition are effective for solving the above-mentioned problems.
[0008]
That is, in the present invention, the fatty acid constituting the fatty acid monoethanolamide is a saturated fatty acid having less than 12 carbon atoms: 15% or less, a saturated fatty acid having 12 carbon atoms: 45-55%
C14 saturated fatty acid: 12-17%
C18 unsaturated fatty acid (unsaturated number: 1): 12-17%
(However, palm kernel fatty acids are excluded)
A dosage form characterized by containing a fatty acid monoethanolamide having the following composition is a liquid, paste-like cleaning composition.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
As the fatty acid composition of the fatty acid monoethanolamide in the present invention, it is preferable to use a mixed fatty acid of the above-mentioned ratio.
That is,
If the fatty acid having less than 12 carbon atoms exceeds 15%, the viscosity increases.
If the fatty acid having 12 carbon atoms is less than 45%, the viscosity is inferior, and if it exceeds 55%, the low temperature stability is lowered.
If the saturated fatty acid having 14 carbon atoms is less than 12%, the viscosity increase is inferior. If it exceeds 17%, the low-temperature stability is deteriorated.
If the unsaturated fatty acid having 18 carbon atoms is less than 12%, the thickening property is poor, and if it is 17% or more, the low temperature stability is deteriorated.
[0010]
The fatty acid monoethanolamide used in the present invention may be produced by any method such as a direct reaction method from oil or fatty acid, or a lower alcohol ester method of fatty acid.
The preparation of the fatty acids may include a single composition of fatty acids within the scope of the present invention or may be within this range using natural oils. The reaction molar ratio of fatty acid and monoethanolamine may be 1: 1 or 1: 2.
Any anionic surfactant, nonionic surfactant, and amphoteric surfactant can be used in the cleaning composition of the present invention depending on the purpose.
In addition, as necessary, chelating agents such as ethanol, urea, polyhydric alcohols, edetic acid, pH adjusters such as citric acid, fragrances, colorants, anti-inflammatory agents such as allantoin and glycyrrhizic acid, bactericides, antiseptic An agent or the like can be used.
The dosage form of the cleaning composition of the present invention can be used in a liquid or paste form .
[0011]
【Example】
Hereinafter, the present invention will be described in more detail with reference to examples.
A kitchen detergent was prepared for each of the fatty acid monoethanolamides synthesized from the fatty acids shown in Table 1 and monoethanolamine (molar ratio of fatty acid to monoethanolamine is 1: 1) according to the test formulation shown below, and its foaming Strength, detergency, viscosity and low temperature stability were measured. The results are shown in Table 1. In addition, the following method was employ | adopted for the test method.
