Disaggregating shales; "Quarternary-O"

[CHESNUT@xxxxxxxxxxxxxxx]

Greetings,
	The commercial product, "Quarternary-O" was a super detergent in
paste form.  This product was sold in the US to clean machinery, etc.  It 
was also an EXCELLENT product to disaggregate shale for microfossils.  The
product was discontinued several years ago.  I have had a difficult time
finding any similar product or method to break down shales that is (1)
inexpensive, (2) nontoxic, (3) easy to use, and (4) fast.  I have been 
spoiled by Quarternary-O (sp.).  Does anyone have an alternative product
or method that matches the above criteria?  There are probably a number of
people on paleonet that would like to know.  Thanks for your help,
	Don Chesnut   chesnut@kgs.mm.uky.edu     [not chestnut@...]
