　結果は表１に示す通りである。比較例１，２，６では、リン酸エステル（Ａ）を用いているが、アルカリ金属の炭酸塩（Ｂ）を配合せずに、アルカリ剤として水酸化ナトリウムやケイ酸ナトリウム（Ｂ’）を配合している。比較例１，２，６では、ｐＨが高いため血液汚れに対する洗浄性には優れているものの、洗浄後に布ダメージがみられた。比較例３，４では、比較例１，２，６に対して、アルカリ剤を減量してｐＨを下げたため、洗浄後の布ダメージは改善されたが、血液汚れに対する洗浄性に劣っていた。また、比較例１～４，６では、いずれも赤ワイン汚れに対する洗浄性に劣っており、また、アルカリ剤としてケイ酸ナトリウムを用いた比較例２，４では皮脂汚れに対する洗浄性にも劣っていた。 The results are shown in Table 1. In Comparative Examples 1, 2 and 6, the phosphoric acid ester (A) is used, but sodium hydroxide or sodium silicate (B') is used as an alkaline agent without blending the alkali metal carbonate (B). It is compounded. In Comparative Examples 1, 2 and 6, although the cleaning property against blood stains was excellent due to the high pH, cloth damage was observed after cleaning. In Comparative Examples 3 and 4, since the amount of the alkaline agent was reduced to lower the pH as compared with Comparative Examples 1, 2 and 6, the cloth damage after washing was improved, but the cleaning property against blood stains was inferior. Further, in Comparative Examples 1 to 4 and 6, the detergency against red wine stains was inferior, and in Comparative Examples 2 and 4 using sodium silicate as an alkaline agent, the detergency against sebum stains was also inferior. ..
　比較例５では、リン酸エステル（Ａ）とアルカリ金属の炭酸塩（Ｂ）を併用しているが、アルカリ金属の炭酸塩（Ｂ）の配合量が少なく、ｐＨが低かったため、血液汚れおよび皮脂汚れに対する洗浄性に劣っていた。比較例７では、リン酸エステル（Ａ）とアルカリ金属の炭酸塩（Ｂ）を併用しているが、水酸化ナトリウム（Ｂ’）を配合しｐＨが高かったため、洗浄後に布ダメージがみられた。 In Comparative Example 5, the phosphate ester (A) and the alkali metal carbonate (B) were used in combination, but the amount of the alkali metal carbonate (B) was small and the pH was low, so that blood stains and sebum It was inferior in cleanability against dirt. In Comparative Example 7, the phosphoric acid ester (A) and the alkali metal carbonate (B) were used in combination, but since the pH was high due to the addition of sodium hydroxide (B'), cloth damage was observed after washing. ..
　これに対し、リン酸エステル（Ａ）とアルカリ金属の炭酸塩（Ｂ）を併用し、かつｐＨを９．５～１１．５の範囲とした実施例１～１５であると、洗浄後の布ダメージを抑えながら、血液汚れを落とすことができ、血液汚れ洗浄性に優れていた。また実施例１～１５であると、赤ワイン汚れに対する洗浄性にも優れていた。更に、リン酸エステル（Ａ）およびアルカリ金属の炭酸塩（Ｂ）に加えてポリオキシアルキレンアルキルエーテル硫酸エステル塩（Ｃ）を配合した実施例１～１４であると、皮脂汚れに対する洗浄性にも優れていた。 On the other hand, in Examples 1 to 15 in which the phosphoric acid ester (A) and the alkali metal carbonate (B) were used in combination and the pH was in the range of 9.5 to 11.5, the cloth after washing was used. It was able to remove blood stains while suppressing damage, and was excellent in cleaning blood stains. Further, in Examples 1 to 15, the detergency against red wine stains was also excellent. Further, in Examples 1 to 14 in which the polyoxyalkylene alkyl ether sulfate ester salt (C) is blended in addition to the phosphoric acid ester (A) and the alkali metal carbonate (B), the cleanability against sebum stains is also improved. It was excellent.
