초록

오염물질을 세탁하는 과정에 있어서 보다 효과적으로 오염물질을 제거하고 표백효과를 부여하기 위해서는 기존의 계면활성제만으로는 한계가 있어 추가적으로 표백과정을 거친다. 본 논문에서는 가장 일반적으로 사용되는 표백활성화제인 TAED (tetraacetylethylenediamine)와 신규로 합성한 표백활성화제(OBA, organic bleach activator, decanoyloxyethoxycarbonyloxybenzenesulfonate)를 비교 평가하였다. 합성한 OBA의 안정성을 개선하고자 제오라이트와 폴리옥시에틸렌 글리콜을 사용하여 코팅처리 한 결과 우수한 안정성을 보였다. OBA는 저온(20 ℃)에서도 우수한 표백효과를 나타냈으며 TAED에 비하여 미생물 분해율이 88%인 물질로 OECD기준(60%) 대비 쉽게 생분해되었다. 세탁과정 중에서 무좀균이나 황색포도상구균에 대해서도 우수한 살균력을 나타내었다.

Not all types of soil occurring on household fabrics can be removed by simple washing with normal surfactants. In order to achieve a satisfactory cleaning effect, an additional treatment step, called bleaching, is required in such cases. Currently, the best known bleach activator is tetraacetylethylenediamine (TAED). In this study, we synthesized a novel organic bleachactivator (OBA), decanoyloxyethoxycarbonyloxybenzenesulfonate. For stabilizing the OBA, it was coated with zeolite and polyethylene glycol. It is found that the stability was enhanced and OBA shows good cleansing and bleaching effects even in cold water (20 ℃). OBA also shows easy biodegradability with 88% in the condition of OECD standard. During the cleansing process, OBA shows excellent microbiological effect against T. mentagrophytes and S. aureus.
