PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Washing Powders.
ARTHUR WARWICK, of 6 Watford Villas, Battersea, Analytical Chemist,
JONATHAN SMITH, of 146 Disraeli Road, Putney, Merchant, and PHILIP
WINTER NICOLLE, of 46 Bridge Road West, Battersea, Merchant do hereby
declare the nature of this invention to be as follows:-
Our invention has for its object the introduction into washing powders of a
powerful antiseptic and germicide, which shall at the same time be detersive in its
action, and also non-poisonous. (Such an improvement is the more necessary, at
the present time, when washing in public laundries has become general, and the
danger of disseminating infection has thereby increased.) For this purpose we
use sodium benzoate, which fulfils most exactly the desired conditions: it is more
effective as a germ-destroyer than any other agent, except corrosive sublimate
which is extremely poisonous: its action extends over a wider field than most
germicides, and it is more useful and effectual in destroying (for example) scarlet
fever germs, which defy the action of most antiseptics except in strong solutions:
while sodium benzoate, in such dilute solutions as are ordinarily made in using
washing powders, is quite effective: it is detersive; and, lastly, non-poisonous.
In applying sodium benzoate to the purpose specified, we proceed to make a
washing powder in the usual way, (or, by preference, as set forth in our Patent
No. 1088 of 1894) to which we then add from to 1 per cent., by weight, of sodium
benzoate, and intimately incorporate it therewith.
Dated this Fourth day of February 1905.

Improvements in the Manufacture of Washing Powders.
ARTHUR WARWICK, of the Minah Mine, Wickes, Montana, United States of
America (and late of 6 Watford Villas, Battersea, London), Analytical Chemist,
JONATHAN SMITH, of 146 Disraeli Road, Putney, Merchant, and PHILIP
WINTER NICOLLE, of 46 Bridge Road West, Battersea, Merchant do hereby
declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement :-
Our invention has for its object the introduction into washing powders of a
powerful antiseptic and germicide, which shall at the same time be detersive in its
action, and also non-poisonous. Such an improvement is the more necessary at
the present time, when washing in public laundries has become general, and the
danger of disseminating infection has thereby increased. For this purpose we use
sodium benzoate, which fulfils most exactly the desired conditions: it is more
effective as a germ-destroyer than any other agent (except corrosive sublimate,
which is extremely poisonous): its action extends over a wider field than most

fever germs, which defy the action of most antiseptics, except in strong solutions:
while sodium benzoate, in such dilute solutions as are ordinarily made in using
washing powders, is quite effective; it is detersive; an 1, lastly, non-poisonous.
In applying sodium benzoate to the purpose specified, we proceed to make a
washing powder in the usual way (or, by preference, as set forth in our Patent
No. 1088 of 1894) to which we then add from one-fourth to one per cent., by weight,
of sodium benzoate and intimately incorporate it therewith.
Although we prefer to use sodium benzoate for the purpose here specified, the
other benzoates of the alkalis, and the benzoates of the alkaline earths, have
similar properties, and we use them for the same purpose.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :
1. The use of sodium benzoate in the manufacture of washing powders,
essentially as here set forth.
2. And, generally, the use of the benzoates of the alkalis and alkaline earths
for the same purpose.
Dated this Fourth day of November 1895.
