Description
本発明は新規な洗浄剤組成物、更に詳細には、
ビルダーとしてアクリル酸−メタクリル酸共重合
体を含むポリエステル−綿混紡繊維に対する再汚
染性の少ない液体洗浄剤組成物に関する。
従来から、リン酸塩、特にトリポリリン酸ナト
リウム、ピロリン酸ナトリウム等の縮合リン酸塩
は良好なビルダー効果を有するので種々の洗剤に
配合して用いられて来た。しかしながら、最近リ
ン化合物の豊栄養化の問題が提起されるようにな
り、これに代わるビルダーの研究がなされ、ポリ
アクリル酸又はその塩が提案された。
このポリアクリル酸及びその塩はビルダーとし
て有効で、液体洗剤及び重質粉末洗剤に配合して
使用できるものである。そこで、本発明者は、ポ
リアクリル酸及びその塩を洗剤ビルダーとして利
用することを検討していたところ、はからずも、
特定のアクリル酸−メタクリル酸の共重合体が優
れたビルダー作用を有すること、そしてこれは特
にポリエステル−綿混紡繊維に対する再汚染性が
アクリル酸のホモポリマーに比較して少ないこと
を見出し、本発明を完成した。
すなわち、本発明は、(a)界面活性剤0.5〜40重
量％、並びに(b)アクリル酸とメタクリル酸が95：
５〜50：50のモル比で共重合したアクリル酸−メ
タクリル酸共重合体又はその塩0.5〜20重量％を
含有することを特徴とする液体洗浄剤組成物を提
供するものである。
本発明でビルダーとして使用されるアクリル酸
−メタクリル酸共重合体のアクリル酸とメタクリ
ル酸のモル比は95：５〜50：50の範囲内であるこ
とが必要であり、就中90：10〜70：30が特に好ま
しい。また、当該共重合体の分子量は2000〜
100000、特に3000〜20000のものが好ましい。ア
クリル酸−メタクリル酸共重合体は酸の形で使用
することもできるが、一般にはアルカリ剤で中和
した塩の形で用いられる。中和に使用されるアル
カリ剤としては、例えば水酸化ナトリウム、水酸
化カリウム、アンモニア、モノー、ジーもしくは
トリーエタノールアミン等が好ましく、場合によ
り水酸化カルシウム、水酸化マグネシウム等を一
部用いてもよい。
本発明において、アクリル酸−メタクリル酸共
重合体又はその塩が配合される洗浄剤成分は一般
に用いられているものの何れでもよい。その中

The present invention relates to a novel cleaning composition, more specifically,
The present invention relates to a liquid detergent composition containing an acrylic acid-methacrylic acid copolymer as a builder and having little re-staining property on polyester-cotton blend fibers. BACKGROUND ART Phosphates, particularly condensed phosphates such as sodium tripolyphosphate and sodium pyrophosphate, have been used in various detergents since they have a good builder effect. However, recently the problem of enrichment of phosphorus compounds has been raised, research has been conducted on alternative builders, and polyacrylic acid or its salts have been proposed. This polyacrylic acid and its salts are effective as builders and can be used in combination with liquid detergents and heavy powder detergents. Therefore, while considering the use of polyacrylic acid and its salts as a detergent builder, the inventor unexpectedly found that
It has been discovered that a specific acrylic acid-methacrylic acid copolymer has an excellent builder effect, and that it has less re-staining property, especially for polyester-cotton blend fibers, than an acrylic acid homopolymer, and the present invention has been made. completed. That is, the present invention provides (a) 0.5 to 40% by weight of a surfactant, and (b) 95% of acrylic acid and methacrylic acid.
The present invention provides a liquid cleaning composition characterized by containing 0.5 to 20% by weight of an acrylic acid-methacrylic acid copolymer or a salt thereof copolymerized in a molar ratio of 5 to 50:50. The molar ratio of acrylic acid to methacrylic acid in the acrylic acid-methacrylic acid copolymer used as a builder in the present invention must be within the range of 95:5 to 50:50, particularly 90:10 to 50:50. Particularly preferred is 70:30. In addition, the molecular weight of the copolymer is 2000~
100000, especially preferably 3000 to 20000. Although the acrylic acid-methacrylic acid copolymer can be used in the form of an acid, it is generally used in the form of a salt neutralized with an alkaline agent. As the alkaline agent used for neutralization, for example, sodium hydroxide, potassium hydroxide, ammonia, mono-, di- or tri-ethanolamine, etc. are preferable, and calcium hydroxide, magnesium hydroxide, etc. may be partially used depending on the case. . In the present invention, the cleaning agent component to which the acrylic acid-methacrylic acid copolymer or its salt is blended may be any commonly used cleaning agent component. Among these, surfactants are usually anionic surfactants,
Non-ionic activators are used. Examples of anionic activators include alkyl ( C8 - C22 ) sulfates, alkyl ( C8 - C22 ) benzenesulfonates, poly(1-100) ethylene glycol alkyl ( C8 - C22 ) ether sulfates, poly(1
~100) Ethylene glycol alkyl ( C8 ~
C22 ) phenyl ether sulfate, alkane ( C8 ~ C22 ) sulfonate, α-olefin ( C8 ~
C 22 ) sulfonates, C 10 to C 22 fatty acid salts, etc. Nonionic surfactants include, for example, poly(1-100) ethylene glycol alkyl (C 8 to
C22 ) ether, poly(1-100) ethylene glycol alkyl ( C8 - C22 ) phenyl ether, C10
~ C22 fatty acid alkylolamide, polyethylene (1-100) glycol fatty acid ( C8 - C22 ) ester, and the like. In addition, a cationic activator or amphoteric activator such as long-chain alkyldimethylamine oxide may be used if necessary. The liquid cleaning composition of the present invention may contain other builders, such as carbonates such as sodium carbonate, potassium carbonate, and sodium sesquicarbonate; sulfuric acid salts such as sodium sulfate, potassium sulfate, and magnesium sulfate. Salts; halides such as potassium chloride and sodium chloride; nitrates such as sodium nitrate; phosphates such as primary sodium phosphate, dibasic sodium phosphate, and tertiary sodium phosphate; silicates such as sodium silicate, etc. inorganic builder or polyethylene glycol,
Examples include organic builders such as polyvinylpyrrolidone, polypropylene glycol, carboxymethyl cellulose, carboxymethyl starch, and citrate. In addition, the liquid cleaning agent of the present invention includes lower alkyl (C 1 - C 4 ) benzenesulfonate, benzoate,
Solubilizers such as urea; methyl alcohol, ethyl alcohol, propyl alcohol, ethylene glycol, propylene glycol, glycerin, etc.
Solvents such as C 1 to C 4 monohydric or polyhydric alcohols; dyes, pigments, fragrances, bactericides, preservatives, etc. can also be blended. As mentioned above, the preferred composition of the liquid cleaning composition of the present invention containing the acrylic acid-methacrylic acid copolymer is as follows. In this specification, unless otherwise specified, % is expressed as % by weight. Acrylic acid-methacrylic acid copolymer 0.5-20% (preferably 1-10%) Surfactant 0.5-40% (preferably 2-20%) Inorganic builder 0-90% Organic builder 0-30% Solvent 0 -20% Solubilizer 0-10% (preferably 2-10%) Other additives 0-5% Of the above composition, 1-10% acrylic acid-methacrylic acid copolymer (a) and (5-20) Oxyethylene alkyl ( C8 - C22 ) ether (b) from 2 to
20%, and further (a) 1-10%, (b) 2-20%
Particularly preferred are those containing 2 to 10% of lower alkyl (C 1 -C 4 )benzenesulfonate (c). Next, an example will be given and explained. Example 1 (1) A cleaning agent having the following composition was prepared. Acrylic acid-methacrylic acid copolymer (molar ratio and molecular weight are shown in Table 1) 5% Dodecyl alcohol ethylene oxide (10
Mol) Adduct 15% Sodium benzoate 5% Ethyl alcohol 3% Polyethylene glycol 200 3% Water Balance (2) The re-staining property of the cleaning agent prepared in (1) on polyester-cotton blend fabric was measured. The recontamination property was measured as follows. Cottonseed oil 150g, cholesterol 30g, cetyl alcohol 6g, oleic acid 30g, palmitic acid 20g, liquid paraffin 10g, solid paraffin
10g, carbon black 7g, ethylene tetrachloride
No. 15 ultrasonic dispersion was soaked in No. 40 cotton broadcloth to make a contaminated cloth. 10cm of this contaminated cloth
5 pieces cut into 10cm x 10cm pieces and 5 pieces of 10cm x 10cm polyester-cotton blend fabric were mixed with 0.25% of the detergent from (1).
% tap aqueous solution and test with a tergotometer.
After washing for 10 minutes, I rinsed it under running tap water, dried it, and then ironed it. The reflectance at 550 mμ of the polyester-cotton blend fabric thus obtained was measured, and the recontamination rate was determined according to the following formula. Recontamination rate (%) = (Reflectance of original fabric) - (Reflectance of treated fabric) / (Reflectance of original fabric) x 100 (3) Results are as shown in Table 1, and the product of the present invention was not recontaminated. low gender.
