	(please include <alt.tanaka-tomoyuki> in the followup,
	if you want me to read it.  it is my personal newsgroup.)


i just read some scientific journalism (by tachibana takashi) on
the technology/science behind this laundry detergent "Attack".

1. i got the impression that the main innovation behind "Attack"
	was the bacteria used in it.  is this not true?

2. do non-Japanese laundry detergents use similar
	micro-biological technology?

  Kao wins big with concentrated Attack
  ...
   Introduced in 1987, Attack was a concentrated detergent that
   promised the same cleaning power at a quarter the scoop size
   of other products. ...

   Ninety percent of the domestic detergent market is now held
   by Attack and similar concentrated products. ...
   concentrated powders hold large shares of the laundry
   detergent markets in the United States and Europe. ...

   The research breakthrough that led to the concentrated powder
   was a rarity for Japan as U.S. manufacturers are usually the
   most innovative in the household products industry. ...

   Detergents contain three major elements: surfactants that
   remove dirt, builders that assist the surfactants, and
   enzymes that remove particular kinds of stains. Traditional
   detergents were large in volume because they added air to the
   agents to make them more solvent.  This was to make the
   detergent dissolve rapidly in water. ...

   The company applied for more than 160 patents during the
   decade of development. ...
