Improvements in or relating to Cleansing or Washing Agents.
I, AMALIA GROSs, of Szederjes Siebenbürgen, 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 :-
This invention relates to au inodorous cleansing agent for washing purposes,
which has for its object to effect a more thorough cleansing of soiled linen, and on
the subsequent ironing thereof to impart to the surface a perfect and regular
gloss.
The novelty in the manufacture of this cleansing agent comprises the addition,
to a solution of the best soda-soap, of petroleum-ether in the proportion of
120 grammes per kilogramme of soap. With this solution, while being continually
stirred, is mixed vinegar-essence in the proportion of 32 grammes per kilogramme
of soap, for the purpose of neutralising any free alkali which may be present in
the soup.
To the mass thus prepared, finely powdered stearine is then added, for the
purpose of accelerating its drying and solidifying, and of imparting a fine and
regular gloss during the ironing process.
After the entire mass has been thoroughly stirred for about half an hour, over a
suitable fire, it is poured out into mould and left to cool.
It will be understood that the above named proportions may be varied without
departure from the principle and scope of the invention.
By the use of petroleum-ether, the cleansing power of the mass is materially
enhanced, and the further advantage is obtained that the linen is rendered
absolutely inodorous, so that the use of ether-essences to get rid of the bad smell. is
rendered superfluous.
The washing is cleansed with this soap-compound in the following manner;
;-
A portion of the dirty linen is first steeped in cold water. A diluted solution of
the detergent compound is then prepared by mixing 80 decagrammes thereof with
20 litres of water, which quantity would suffice for the washing of 60 to 80 pieces.
The soap-compound is at once dissolved in the water which thereby acquires the
aspect of milk. Then the steeped articles are placed in the prepared water, and
boiled over a fire for about 1 hours. The wash is then rinsed twice in clean
water. Coloured articles, however, must not be boiled; but it will be sufficient to
wash them in the first rinsing water, without using any soap whatever.
It may be remarked that the cleansing of the wash may also be effected by
washing or boiling the articles in soapy water with the addition of petroleum-ether
and vinegar-essence, and subsequently rinsing them out in clean water.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is ;-
1. A cleansing agent for washing purposes characterised by the addition of
petroleum-ether to a solution of soda-soap in water and the mixing of the resulting
mass with vinegar-essence for the purpose of neutralising any free alkali therein
contained.
2. A cleansing agent for washing purposes characterised by the addition to the
mass described in Claim 1 of finely pulverised stearine for the purpose of accelerating
the desiccation and solidification of the mass and of imparting a fine regular gloss
during the ironing process.

and vinegar essence with soapy water in which the articles are washed or
boiled.
