Description
[第1の実施形態]
本発明の第1の実施形態は、油脂分解酵素、吸湿剤、酵素安定化剤、溶剤及び調整水を含有する防汚洗浄剤である。油脂分解酵素とは、前述のように、Enzyme Classification 番号E.C.3.1.1(カルボン酸エステルヒドロラーゼ)下で分類された酵素を示す。従って、油脂分解酵素は、「モノ−、ジ−及びトリグリセリド、リン脂質(すべての種類)、チオエステル、コレステロールエステル、ワックス−エステル、クチン、スベリン、合成エステル等、脂質に存在するエステル結合の少なくとも1つのタイプに対して加水分解活性を示すもの」である。脂肪分解酵素は、リパーゼ、ホスホリパーゼ、エステラーゼ又はクチナーゼとして称せられて来たものである。
ΔA405=A405(検体の吸光度)−B405(ブランクの吸光度)
X軸側を標準酵素溶液の活性値LU/mlとし、Y軸にΔA405をプロットして標準酵素溶液の測定結果から検量線の直線式を導出する。検量線の直線式を用いて酵素サンプル溶液のΔA405から活性値LU/mlを見積もる。更に、以下の式から、酵素サンプル溶液1g中の活性値を算出する。
活性値=A×B/C
ここで、Aは前記直線式から見積もられた1ml当たりの活性値、Bは酵素サンプル溶液の希釈倍率、Cはサンプル重量(g)である。本発明に係る防汚洗浄剤は、酵素活性が1LU/g以上の油脂分解酵素を用いている。
酵素の不安定性を解消するため、酵素安定化剤を配合される。酵素安定化剤としては、グリシン、リジン等のアミノ酸類、ソルビット、マルチトール、キシリトール等の多糖類、グリセリン(ジ・トリ・ペンタ・ポリ)、プロピレングリコールや1,3-ブチレングリコール等の多価アルコールが用いられる。更に、溶剤としては、エチレングリコールモノメチルエーテル、エチレングリコールモノエチルエーテル、ジエチレングリコールモノブチルエーテル等のグリコール系溶剤やイソプロピルアルコール等のアルコール系溶剤が用いられる。調整水としては、イオン交換樹脂、蒸留、逆浸透等により得られた精製水を用いることが好ましい。
また、リパーゼの配合量が10mass%を越えると、配合量の増加に伴う防汚・洗浄効果の増強が抑制される傾向にあることが確認されている。即ち、リパーゼの配合量が10mass%を越えると酵素活性が効率的に発現することが困難となってくると考えられ、吸湿剤や酵素安定化剤の配合量を適宜に調整することにより水分や酵素の安定性を付与する必要がある。前述のように、表に示す試料では、酵素活性が100KLU/gのリパーゼが用いられており、リパーゼの配合量が10mass%である場合、酵素活性の失活が無ければ、防汚洗浄剤の酵素活性は10KLU/gとなる。同様に、酵素活性の失活が無ければ、リパーゼの配合量が0.001mass%である場合、防汚洗浄剤の酵素活性は10LU/gとなり、防汚洗浄剤として利用可能な酵素活性が保持されることになる。
本発明に第2の実施形態は、第1の実施形態に含まれる油脂分解酵素、吸湿剤、酵素安定化剤、溶剤及び調整水と共に、界面活性剤、アルカリ剤が配合される防汚洗浄剤である。表5に示すように、油脂分解酵素としてはリパーゼ (novozymes社製、LIPEX)、吸湿剤にはグリセリンとピロリドンカルボン酸ナトリウム(PCA−Na)、酵素安定化剤にはアガロース、溶剤には3−メトキシ−3−メチルブタノ−ル、調整剤として精製水、界面活性剤には、モノオレイン酸ポリオキシエチレンソルビタン(日本油脂(株)製、商品名:ノニオンOT−221)、アルカリ剤として重炭酸ソーダが配合されている。尚、安定化剤として配合されたアガロースには固定化剤としての機能も有し、対象物にリパーゼを固定化することができる。界面活性剤によって油脂成分を均一に分散させ、リパーゼにより分解し、この過程で生成された脂肪酸をアルカリ剤で中和し石鹸化することにより、高効率に油脂成分からなる汚れを除去することができる。
