  • Publication number: 20250089707
    Abstract: An eco-friendly quarantine composition has a function of killing phospholipid enveloped viruses, The eco-friendly quarantine composition includes: 10 to 40 wt. % of polyoxyethylene lauryl ether, 0.01 to 10 wt. % of polyoxyethylene 2-ethylhexyl ether, 0.01 to 10 wt. % of polyoxyethylene polyoxypropylene alkyl ether, and a balance of solvent, based on the total 100 wt. % of the composition. The eco-friendly quarantine composition may have 100% of SARS-CoV-2 virus removal rate in 1 minute and an effect of killing 100% of highly pathogenic avian influenza virus in 1 to 10 minutes. The composition has low cytotoxicity such that IC50 value (%) for human epithelial keratinocyte cells (HaCaT), human bronchial epithelial cells (BEAS-2B), and human monocyte cells (THP-1) is in a range of 0.003 to 0.0045, and effects of having antibacterial activity against non-pathogenic strains, and pathogenic strains.

  • Patent number: 5614564
    Abstract: The present invention relates to a lignocellulose solution and its production method, further to a degradable foam and its production method. The degradable foam of the present invention is produced by foaming and hardening with an ordinary foaming agent and hardening agent the lignocellulose solution which is obtained by dissolving lignocellulose and/or its derivatives in aliphatic polyester polyol, or else such solution with photodegradation promoters added thereto; and is also produced by foaming and hardening with an ordinary foaming agent and an ordinary hardening agent the lignocellulose solution which is obtained by dissolving lignocellulose and/or its derivatives in the bio-/photo-degradable aliphatic polyester polyol which is obtained by a polycondensation of the dicarboxylic acid composed of aliphatic dicarboxylic acid and keto containing dicarboxylic acid or its ester and aliphatic diol.
