Description
本発明は、衣料用粉末洗浄剤組成物、及び衣料の洗浄方法に関する。 The present invention relates to a powder cleaning composition for clothing and a method for washing clothing.
粉末洗浄剤組成物では、洗浄液のｐＨをアルカリ性にすることで洗浄力が高まることから、一般的にアルカリ成分が配合されている。近年では、アジア地域の洗濯機の普及が増加する傾向にあるが、洗浄力、経済性の観点、文化的背景、洗濯意識などから、手洗い洗濯が依然として広く行われている。手洗い洗濯は、洗濯機による洗濯と比較した場合、汚れの落ち具合、衣料の種類など、状況に応じたきめ細かい洗浄に適している。
しかし、手洗い洗濯は、肉体的、精神的疲労感が伴う作業である。また、洗浄剤を計量する場合や溶解する場合に手で粉末洗浄剤をつかみ水の中で撹拌するため、洗浄剤中の成分の影響により刺激を感じる場合がある。さらに洗濯中は、長時間洗濯液の中に手を入れているため、洗浄成分の影響で手にぬるつきや刺激を感じ、また洗濯後にも手の乾燥や洗浄成分の残留によるべたつきが発生するために不快感を伴い、ハンドクリームなどでケアしなければならない場合がある。そのために、衣料用洗浄剤に関しても洗浄成分のマイルド性を訴求した商品が求められている。
In the powder detergent composition, since the cleaning power is increased by making the pH of the cleaning liquid alkaline, an alkali component is generally blended. In recent years, there has been a tendency for the spread of washing machines in the Asian region to increase, but hand-washing is still widely practiced from the standpoints of detergency, economy, cultural background, and washing awareness. Hand-washing is suitable for fine cleaning according to the situation, such as how soil is removed and the type of clothing, compared to washing with a washing machine.
However, hand-washing is a work accompanied by physical and mental fatigue. In addition, when measuring or dissolving the cleaning agent, the powder cleaning agent is grasped by hand and stirred in water, so that irritation may be felt due to the influence of the components in the cleaning agent. In addition, during washing, hands are put in the washing solution for a long time, so the hands feel wet and irritating due to the effects of the cleaning ingredients, and stickiness due to dry hands and residual cleaning ingredients occurs even after washing. Because of this, it may be uncomfortable and must be treated with hand cream. For this reason, there is a demand for products that appeal to the mildness of the cleaning ingredients for clothing cleaners.
特許文献１には、酸源と炭酸源とカリウムイオンを組み合わせることにより、冷水での溶解性を改善した顆粒状洗剤組成物に関する技術が開示されている。
特許文献２には、陰イオン界面活性剤、非イオン界面活性剤、過炭酸塩を含む炭酸源を組み合わせることにより、衣類に付着した食物のシミや黄ばみなどの汚れを効果的に落とすことができる粉末洗浄剤組成物に関する技術が開示されている。
特許文献３には、特定のアニオン界面活性剤と、プロテアーゼと、（ａ）蛋白脱水作用を有する物質、（ｂ）渋味を有する物質、（ｃ）皮膜形成機能を有する物質、（ｄ）血管収縮作用を有する物質のいずれかと、を組み合わせることにより、皮膚または粘膜に対する化学物質の刺激を低減させること及びこれらの物質を配合して低刺激性でかつ良好な洗浄力を有する洗浄剤組成物に関する技術が開示されている。
Patent Document 1 discloses a technique related to a granular detergent composition having improved solubility in cold water by combining an acid source, a carbonate source, and potassium ions.
Patent Document 2 can effectively remove stains such as stains and yellowing of food adhering to clothing by combining an anionic surfactant, a nonionic surfactant, and a carbonate source containing a percarbonate. Techniques relating to powder cleaning compositions are disclosed.
Patent Document 3 discloses a specific anionic surfactant, a protease, (a) a substance having a protein dehydrating action, (b) a substance having astringency, (c) a substance having a film forming function, and (d) a blood vessel. The present invention relates to a detergent composition that reduces the irritation of a chemical substance on the skin or mucous membrane by combining with any of substances having a contractile action and has a low deterrence and good detergency by blending these substances. Technology is disclosed.
手洗い洗濯では、手肌への影響やぬるつきが少ないことが望まれるが、特許文献１、特許文献２は、衣料を手洗いする際の感触に関して言及していない。
特許文献３は、手の刺激低減を記してはいるが、アルカリ源となる無機炭酸塩、ケイ酸塩を多く含むため、洗濯時の手の感触は改善されていない。また、洗濯後も手のぬるつきが取れにくく、すすぎにくい。
In hand-washing washing, it is desired that there is little influence on hand skin and sliminess, but Patent Document 1 and Patent Document 2 do not mention the touch when washing clothes.

洗浄液の調製のため組成物と混合する水のアルカリ度は１０ｍｇＬ以上３００ｍｇ／Ｌ以下が好ましい。また、組成物と混合する水のドイツ硬度は１゜ｄＨ以上５０゜ｄＨ以下が好ましい。よって、組成物と混合する水は、アルカリ度１０ｍｇ／Ｌ以上３００ｍｇ／Ｌ以下、ドイツ硬度１゜ｄＨ以上５０゜ｄＨ以下の水が挙げられる。
本発明の洗浄液のｐＨは実施例に記載のｐＨの測定法で求められたｐＨであり、ガラス電極を用いて測定されたｐＨである。

Therefore, the water mixed with the composition includes water having an alkalinity of 10 mg / L to 300 mg / L and a German hardness of 1 ° dH to 50 ° dH.
The pH of the cleaning liquid of the present invention is a pH determined by the pH measurement method described in the examples, and is a pH measured using a glass electrode.
洗浄に使用される水は、地質の影響や微生物の存在により、炭酸、炭酸イオン、炭酸水素イオンを含有することが知られており、これらのイオン量の指標としてアルカリ度が用いられている。水中での炭酸イオンと炭酸水素イオンのｐＫａはそれぞれ１０．３及び６．３（２０℃）であることから、ｐＨ１０．３並びに６．３近傍でｐＨ緩衝能を持つため、洗浄液のｐＨが各ｐＫａに近づくと少量の酸成分やアルカリ成分ではｐＨの変化が起きにくくなる。 The water used for washing is known to contain carbonic acid, carbonate ion, and hydrogen carbonate ion due to the influence of geology and the presence of microorganisms, and alkalinity is used as an index of the amount of these ions. Since the pKa of carbonate ion and hydrogen carbonate ion in water is 10.3 and 6.3 (20 ° C.), respectively, the pH of the cleaning solution is different because the pH buffer capacity is around pH 10.3 and 6.3. As pKa is approached, changes in pH are less likely to occur with small amounts of acid and alkali components.
一般的な洗浄に使用される水のｐＨが６以上８以下であることを考慮すると、アルカリ度の主因子は炭酸水素イオンであり、洗浄ｐＨを水よりも低下させる場合にｐＨ６．３付近で緩衝作用を発現する。アジア地域におけるアルカリ度は総じて高く、５０ｍｇ／Ｌ以上２００ｍｇ／Ｌ以下であるため、酸性成分を添加してもｐＨが変化しにくい水である。 Considering that the pH of water used for general washing is 6 or more and 8 or less, the main factor of alkalinity is bicarbonate ion, and when the washing pH is lowered than water, the pH is around 6.3. Expresses buffering action. Since the alkalinity in the Asian region is generally high and is 50 mg / L or more and 200 mg / L or less, it is water whose pH hardly changes even when an acidic component is added.
洗浄に使用される水のドイツ硬度は、１°ｄＨ以上、更に２°ｄＨ以上、更に３°ｄＨ以上、更に５°ｄＨ以上であっても使用できる。一方、洗浄に使用される水のドイツ硬度は、洗浄力の観点から５０°ｄＨ以下、好ましくは４０°ｄＨ以下、より好ましくは３０°ｄＨ以下、より好ましくは２５°ｄＨ以下である。 The German hardness of water used for washing can be 1 ° dH or higher, 2 ° dH or higher, 3 ° dH or higher, or 5 ° dH or higher. On the other hand, the German hardness of water used for cleaning is 50 ° dH or less, preferably 40 ° dH or less, more preferably 30 ° dH or less, more preferably 25 ° dH or less from the viewpoint of cleaning power.
本明細書におけるドイツ硬度（°ｄＨ）とは、水中におけるカルシウム及びマグネシウムの濃度を、ＣａＣＯ３換算濃度で１ｍｇ／Ｌ（ｐｐｍ）＝約０．０５６°ｄＨ（１°ｄＨ＝１７．８ｐｐｍ）で表したものを指す。洗浄に使用される水のドイツ硬度の調整は、例えば、本明細書の実施例に記載の方法のように、硬度成分の種類や添加量から計算される値に基づいて行うことができる。また、洗浄に使用される水として、水道水等の硬度が不明の水を用いる場合には、水のドイツ硬度は、下記に記載のエチレンジアミン四酢酸二ナトリウム塩を使用したキレート滴定法で求められる。

洗浄及びすすぎに用いる水は、次のように調製した。塩化カルシウム・２水和物７８．５０ｇ及び塩化マグネシウム・６水和物７３．５８ｇを１Ｌのイオン交換水で溶解させた濃厚原液を調製した。この濃厚原液は、カルシウム／マグネシウム＝６／４（モル比）であった。得られた濃厚原液を、アルカリ度１００ｍｇ／Ｌ（ＣａＣＯ３換算）、ｐＨ７．５の希釈用水で希釈し、１０゜ｄＨに調整して洗浄及びすすぎに用いる水とした。前記希釈用水は、イオン交換水に炭酸水素ナトリウムを添加してアルカリ度を調整し、塩酸を添加してｐＨを調整して得た。
洗浄率（％）＝［（洗浄後の反射率−洗浄前の反射率）／（白布の反射率−洗浄前の反射率）］×１００
白布は、ラー油汚染布の調製に用いた綿メリヤス布（綿ニット未シル、綿１００％、谷頭商店）の未汚染状態の布である。
反射率は日本電色工業（株）製ＮＤＲ−１０ＤＰで４６０ｎｍフィルターを使用して測定した。洗浄率は、７０％以上が合格であり、数値が高い程より好ましい。
[3] Evaluation method of detergency 9 g of a powder detergent composition for clothing shown in the table with respect to 3 L of water having a German hardness of 10 ° dH, an alkalinity of 100 mg / L (calculated as CaCO 3 ), pH 7.5 and 20 ° C. Diluted and dissolved in a tub. Thereafter, one undergarment sewn with five litter oil-contaminated cloths prepared as described below and two underwears of the same size for adjusting the bath ratio were put, and the whole was stirred. The bath ratio was 8. The underwear used was Gunze YG (round neck T-shirt, M size, 100% cotton). Thereafter, the contaminated cloth was uniformly rubbed by hand for 10 minutes. After rinsing twice with 3 L of water similar to the water used to dilute the composition, it was squeezed by hand to dehydrate and dried. The cleaning rate was measured by the following formula.
The water used for washing and rinsing was prepared as follows. A concentrated stock solution was prepared by dissolving 78.50 g of calcium chloride dihydrate and 73.58 g of magnesium chloride hexahydrate with 1 L of ion exchange water. This concentrated stock solution was calcium / magnesium = 6/4 (molar ratio). The obtained concentrated stock solution was diluted with water for dilution having an alkalinity of 100 mg / L (calculated as CaCO 3 ) and pH 7.5, adjusted to 10 ° dH, and used as water for washing and rinsing. The dilution water was obtained by adding sodium bicarbonate to ion exchange water to adjust the alkalinity, and adding hydrochloric acid to adjust the pH.
Washing rate (%) = [(reflectance after washing−reflectivity before washing) / (reflectance of white cloth−reflectivity before washing)] × 100
The white cloth is a non-contaminated cloth of a cotton knitted cloth (cotton knit not sill, 100% cotton, Yagami Shoten) used for the preparation of the ra oil-contaminated cloth.
The reflectance was measured using NDR-10DP manufactured by Nippon Denshoku Industries Co., Ltd. using a 460 nm filter. The cleaning rate is 70% or more, and the higher the value, the more preferable.
