PURPOSE:To improve the stability of an inorg. acid salt compd. and to greatly improve the deodorization performance for ammonia and mercaptan, etc., by using in combination with the inorg. acid salt compd. of Al and/or Zn, ascorbic acid compd., and copper compd. CONSTITUTION:Aluminum salt such as aluminum chloride and aluminum nitrate and zinc salts such as zinc sulfate and zinc chloride are exemplified as the inorg. acid salt compd. of the component (A). The ascorbic acid compd. of the component (B) is exemplified by L-ascorbic acid, erysorbic acid, etc. The copper compd. of the component (C) may be any of an inorg. acid salt, org. acid salt, complex, or oxide. This ascorbic acid compd. improves the stability of the inorg. acid salt compd. and the copper compd. improves the deodorizability. The compsn. contg. such components (A), (B), (C) are useful for a deodorizer, freshness maintaining agent, germicide mildewproofing agent, etc. |
