Manufacture of Detergent.
We SALO WOHLE of No. 237 Shaftesbury Avenue in the County of London,
Chemist, and ANDREW CLARKE IRWIN of Ivy House, Highgate, in the County of
Middlesex, Merchant, do hereby declare the nature of this invention to be as
follows:-
This invention relates to the manufacture of a detergent especially applicable for
washing wool and other animal fibres and separating grease therefrom.
For this purpose we use as the base of our detergent, certain fruits of plants of
the sapindus genus, of acacia concinna, entada scandens, and of horse chesnut, and
the bark of cordia augustifolia. We agitate these fruits preferably stripped or the said
bark in water to which we preferably add infusion of leaves of albizzia amara, heated
not quite to boiling point and mixed with a small proportion of glycerine oleiene,
sperm oil, spirits of turpentine, paraffin spirits of ammonia, citric or tartaric acids
according to the nature of the plant treated. Or instead of agitating these substances
in water we sometimes prefer to use the spent wash from distilleries. After sufficient
extraction, we filter press the material, and to the liquor we preferably add chalk or
prepared chalk to neutralise the injurious acids.
Dated this 28th day of January 1896.

We, SALO WOHLE of 237 Shaftesbury Avenue in the County of London, Chemist,
and ANDREW CLARKE IRWIN of Ivy House, Highgate, in the County of Middlesex,
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:-
This invention relates to the manufacture of a detergent specially applicable for
washing wool and other animal fibres and separating grease therefrom. It may also
be used for cleansing purposes generally, except for cotton or linen goods.
For this purpose we steep about 20 lbs. of the leaves of albizzia amara in about
120 gallons of water, hot but not boiling. To the infusion strained we add a little
glycerine, olein, paraffin, spirits of turpentine and citric or tartaric acid or the
equivalent in lime or lemon juice, using from to 1 per cent. of each. We sometimes
add from 5 to 10 per cent. of cane molasses. We skin the fruits of the sapindacia,
sometimes adding the kernels, or instead of these we use beans of the acacia concinna
or dried and skinned horse chesnuts. We thoroughly mix any one or more of the
above products, preferably bruised, with the extract of the albizzia amara and digest
the mixture at a temperature of about 160° Fahr., but not exceeding 180° Fahr.

page_text: We filter press the extract and add liquid ammonia but not enough to discolor red
litmus paper. The glycerine and other chemical substances, instead of being added
in the first instance to the albizzia infusion, may be added after the filter pressing.
Instead of infusing the albizzia with water it may be infused with spent wash from
distilleries. When the detergent is to be used for hair or skin wash the spent wash
or sapindus saponaria or turpentine should not be used, and, instead of the
ammonia, about 10 per cent. of melon, cucumber or rhubarb juice may be added raw.
Also sufficient antiseptic such as sodium or calcium sulphites should be added to
prevent fermentation.
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 :
The manufacture of a detergent by treating the substances mentioned or their
equivalents substantially as herein described.
