【発明の属する技術分野】
本発明は、汚れ放出剤及び洗浄剤組成物に関する。
【0002】
【従来の技術及び発明が解決しようとする課題】
繊維の洗濯時に繊維に予め汚れ放出効果(ソイルリリース効果)を付与することは、通常の洗浄方法に比べて極めて優れた洗浄効果をもたらす可能性を有する。ポリエステル混紡布等の疎水性の合成繊維の洗浄において効果的な汚れ放出剤としては、テレフタレートを主体とする化合物が知られている(US 3416952、US 3557039、US 4795584等)。しかしながら、これらの汚れ放出剤はポリエステルを混紡させた疎水性の合成繊維の布に対しては極めて優れた効果を示すが、比較的親水性の高い木綿繊維に対しては充分な効果が発現されないことが問題視されていた。
【0003】
木綿繊維に対する汚れ放出剤としては、例えばポリアミン誘導体(WO 9742285)、窒素を含有するポリマー(DE 19649288)等が知られている。しかしながらこれらの化合物も繊維への吸着効率が、界面活性剤や温度、pH等の影響を強く受け、充分な効果が得られない場合が多い。
【0004】
本発明の課題は、木綿布に対して優れた汚れ放出効果を示し、高い洗浄効果を発現できる汚れ放出剤及び洗浄剤組成物を提供することである。
【0005】
【課題を解決するための手段】
本発明は、下記一般式(1)で示される化合物及び/又は下記一般式(2)で示される化合物からなる汚れ放出剤、並びに該化合物0.01〜50重量%を含有する洗浄剤組成物に関する。

【発明の実施の形態】
本発明の汚れ放出剤は、布類の洗濯時に汚れの除去をより効果的に行えるという機能を布に与えることができるものである。即ち、木綿繊維の布を本発明の化合物を含む洗浄剤等を用いて通常の洗浄を行うことによって、繊維表面に汚れ放出機能を付与させることができる。例えば木綿繊維を洗濯機中又は手洗いによって約3分〜2時間、本発明の化合物を含有する洗浄剤組成物に浸漬又は洗浄し、水で充分すすいだ後、脱水乾燥させるという通常の洗浄サイクルを繰り返すことによって汚れ放出機能が布に付与され、高い洗浄効果が発現される。好ましい浸漬又は洗浄時間は5分以上1時間以内であり、より好ましくは8分以上20分以内である。特に本発明の特徴としては洗浄回数が多くなる程より優れた効果を得ることができることである。

As an effective soil release agent for cleaning hydrophobic synthetic fibers such as polyester blended fabrics, compounds based on terephthalate are known (US 3416952, US 3557039, US 4795584, etc.). However, these soil release agents have an extremely excellent effect on a hydrophobic synthetic fiber cloth blended with polyester, but do not exhibit a sufficient effect on relatively hydrophilic cotton fibers.

After deaeration for 30 minutes under reduced pressure, the reaction product was extracted from the autoclave to obtain 1980 g of a reaction product. 500 g of this reaction product, 300 g of isopropyl alcohol and 107 g of methyl chloride were charged into an autoclave and reacted at 90 ° C. for 7 hours. After completion of the reaction, unreacted methyl chloride was removed under reduced pressure, and the filtrate was collected by filtration and dried to obtain 607 g of the desired product.

Synthesis Example 3 [Synthesis of POE (10) dimethylamine oxide]
An autoclave was charged with 500 g of N, N-dimethylethanolamine and 3.15 g of potassium hydroxide, 2269 g of EO was gradually blown at 180 ° C., and the whole amount was injected, followed by aging at 160 ° C. for 3 hours. After deaeration for 30 minutes under reduced pressure, the product was extracted from the autoclave to obtain 2770 g of a reaction product. 500 g of this reaction product was put into a four-necked flask equipped with a stirrer, a condenser, a thermometer, and a dropping funnel, 850 g of water and 1.02 g of citric acid were added, and the temperature was raised to 85 ° C. While maintaining at 85 ° C., 108.2 g of 35% aqueous hydrogen peroxide was slowly added dropwise, and after completion of the addition, aging was performed for 3 hours. 2.12 g of caustic soda was added, and the mixture was further aged for 2 hours and then cooled. The pH was adjusted to neutral with an aqueous hydrochloric acid solution to obtain 1460 g of the desired product.

Example 1
(1) Repeated washing of cotton fiber cloth and creation of contaminated cloth
A 10 cm × 10 cm cotton cloth is dissolved in a 4 ° DH hard water with a powder detergent composition comprising the ingredients shown in Table 1 to prepare a 0.06% aqueous solution, and the pH is adjusted to 10.5 with NaOH or HCl. Add 5 pieces of the above cotton cloth to the detergent aqueous solution and stir and wash with a turgotometer at 20 ° C. for 10 minutes at 100 rpm. After rinsing under running water, it is dried in a room at 25 ° C. and 50% RH for 1 hour or more after removing water sufficiently by a centrifugal dehydrator. After repeating this washing process three times, model sebum soil consisting of 60% cotton seed oil, 10% cholesterol, 10% oleic acid, 10% palmitic acid and 10% solid paraffin is applied to the washed cotton cloth 10cm × 2 g per 10 cm was uniformly applied to prepare a sebum-stained cloth. Contaminated cloth which performed this process about each composition of Table 1 was produced.
[0024]
(2) Cleaning conditions, cleaning methods and evaluation methods A detergent composition comprising the ingredients listed in Comparative Product 1 in Table 1 was dissolved in 4 ° DH hard water to prepare a 0.06% aqueous solution, and NaOH or HCl. Use to adjust the pH to 10.5. Five cotton-stained cloths corresponding to the respective compositions are added to the cleaning composition aqueous solution, and the mixture is washed with stirring by a tartometer at 20 ° C. for 10 minutes at 100 rpm. After rinsing under running water, an iron press treatment was performed.
[0025]
Next, the reflectance at 460 nm of the raw cloth before washing, the contaminated cloth prepared after repeated washing, and the contaminated cloth after final washing was measured with a self-recording colorimeter (Shimadzu Corporation). Was calculated.
Washing rate (%) = [(reflectance after final cleaning−reflectance after preparation of contaminated cloth) / (reflectance of raw cloth−reflectance after preparation of contaminated cloth) × 100
Table 1 shows the average values for the five contaminated cloths.
