Description

【0001】
【発明の属する技術分野】
本発明は、液体洗浄剤組成物の製造方法に関する。
【0002】
【従来の技術】
一般家庭で通常行われる水道水を用いた洗浄において、水道水中の殺菌を目的とした残留塩素による被洗浄物の変褪色が問題となっている。特に衣料等の洗濯のようにすすぎ工程に水道水を用い、乾燥まで含めて水道水との接触時間が長いものに変褪色が問題となっている。
【0003】
塩素捕捉剤を用い、水道水中の残留塩素を低下させて被洗浄物の変褪色を防止する試みは種種の先行技術において記載されている。例えば、特許文献1〜3等には塩素捕捉剤を用いる液体洗浄剤組成物が記載されているが、これらは洗浄工程では十分な塩素捕捉効果を有していても、すすぎ工程においては残留量が低く効果が不十分であったり、保存により組成物が変色するといった問題があった。
【0004】
すすぎ工程への残留性が高く、被洗浄物の変褪色防止性に優れる剤として、イミノ基(−NH−)、アミド基(−CONH−)、エステル基(−COO−)、エーテル基(−O−)を有するアミン化合物が知られているが、融点が高いため、生産性良く液体洗浄剤組成物に配合することが困難であった。

In particular, tap water is used in a rinsing step like washing clothes, and the contact time with tap water including drying is long, and discoloration is a problem.
[0003]
Attempts to use chlorine scavengers to reduce residual chlorine in tap water to prevent discoloration of the object to be cleaned have been described in various prior arts. For example, Patent Literatures 1 to 3 and the like describe liquid detergent compositions using a chlorine scavenger, but these have a sufficient chlorine scavenging effect in the washing step, but have a residual amount in the rinsing step. And the effect is insufficient, or the composition discolors upon storage.
