Year: 1861

page_text: City of London, Merchant, for the Invention of "AN IMPROVED COM-
POSITION FOR CLEANING AND REVIVIFYING WOOLLEN CLOTHS AND OTHER
FABRICS, AND THE COLORS THEREOF."-A communication from abroad by
Alfred Thomas, of Paris, France.
Sealed the 17th June 1862, and dated the 20th December 1861.
PROVISIONAL SPECIFICATION left by the said Eugene Etienne Pereau
at the Office of the Commissioners of Patents, with his Petition, on the
20th December 1861.
I, EUGENE ETIENNE PEREAU, of Moorgate Street, in the City of London,
Merchant, do hereby declare the nature of the. said Invention for "AN IM-
PROVED COMPOSITION FOR CLEANING AND REVIVIFYING WOOLLEN CLOTHS AND OTHER
FABRICS, AND THE COLORS THEREOF," (communicated to me from abroad by Alfred
Thomas, of Paris, France) to be as follows:-
This composition is made either white or colored, and in either case I give
it the trade name of "eau écarlate." It cleans, removes the stain from and
revivifies the color of woollen and other fabrics, as well as the fabrics them-
selves. It is formed of citric acid, carbonate of potash, alum, alcohol, and
water, to which coloring matter, say, for instance, cochineal, may be added to

page_text: impart the color required. Other acids or acid salts, such as oxalic acid,
tartaric acid, cream of tartar, nitric acid, sulphuric acid, salt of sorrel, or other
acid salt capable of producing the same effect may be substituted for the citric
acid in the composition of the "eau écarlate."
I do not confine myself to any particular proportions of the ingredients of
which my improved composition is formed; but I have found the following to
answer well
