Abstract

Cleaning formulations suitable for use as cleaning solutions for magnetic recording devices, heads, cables and other uses which benefit from reduced residue deposition consist primarily of water. The shipment of water world wide is expensive and unnecessary if a concentrate can be formulated for appropriate dilution to the final product. To be effective, the concentrate should permit as much dilution as possible so as to produce the maximum amount of the final product in its diluted form as possible. In addition, the concentrate should be in a form which minimizes health and safety hazards while remaining stable and well mixed for a reasonable time.

Preparation of a Water-Based Cleaner From a Concentrate

      Cleaning formulations suitable for use as cleaning solutions
for magnetic recording devices, heads, cables and other uses which
benefit from reduced residue deposition consist primarily of water.
The shipment of water world wide is expensive and unnecessary if a
concentrate can be formulated for appropriate dilution to the final
product.  To be effective, the concentrate should permit as much
dilution as possible so as to produce the maximum amount of the final
product in its diluted form as possible.  In addition, the
concentrate should be in a form which minimizes health and safety
hazards while remaining stable and well mixed for a reasonable time.

      A concentrate can thus be formulated in any dilution but
preferably into round numbers of units per unit concentrate.
Practically the concentrate should yield at least hundreds of units
of the final dilution per unit concentrate.  The upper limit
practical would vary for each formulation depending on the
miscibility of the components and their health and safety properties.
The inclusion of a significant amount of water in the concentrate
(60-95%) is likely to remain desirable so as to minimize the
flammability of the mixture and maintain a fluid consistency.

      A useful water-based cleaner concentrate could thus be produced
using 15.0 grams of a tridecyl ether of polyoxyethylene and 25.0
grams of ammonium carbonate in 96.0 grams of distille...
