PERFECTIONNEMENTS RELATIFS AUX SAVONS ET
A LEUR FABRICATION
La présente invention se rapporte à un procédé de fabrica- tion des savons destinés aux eaux salines telles que l'eau de mer; elle se rapporte aussi aux produits fabriqués suivant ce procédé.
Les inventeurs ont découvert que les savons préparés avec des acides gras à poids moléculaire faible moussaient à l'eau de mer; ils ont donc eu l'idée d'employer comme matière première pour la fabrication du savon, des produits naturels à haute teneur en acides gras à faible poids moléculaire, après avoir au besoin retiré de ces produits les acides gras à poids moléculaire plus élevé.
Dans ces conditions, conformément à l'invention, on fabrique un savon à partir de corps gras composés en majeure partie d'acides @
<Desc/Clms Page number 2>
gras poids moléculaire faibles c'est-à-dire inférieurs à 210 ; ces corps gras comprenant notamment les acides lauriques, capriques, caproïques, capryliques, pourront être obtenus en retirant, par exemple par distillation, les acides myrîstiques, palmitiques, stéariques, oléiques, etc..; on peut aussi partir de corps gras naturels à haute teneur en acides lauriques, capriques, caproïques ou capryliques.
Il est avantageux de fabriquer un tel savon à l'aide de l'huile extraite du Litsea Sebifera ou des plantes des familles si- milaires; cette plante se trouve en Indochine où elle est connue sous le nom de BO I LO I NHOT ou MONHOT,
Dans un exemple de réalisation, on prend de l'huile de coprah que l'on distille de façon à séparer les acides gras à point d'ébullition compris entre 125 et 176 degrés centigrades sous une pression de 10 millimètres de mercure. Puis on saponifie ces acides gras en les faisant passer dans une canalisation sur laquelle est branchée une arrivée de soude mélangée à de la potasse ; lemélange se fait d'une façon continue à l'intérieur de la canalisation et la saponification se poursuit de préférence dans un récipient.
Dans une autre réalisation, on part d'huile de BO I LO I NHOT que l'on saponifie sans distillation préalable.
L'invention couvre aussi le procédé de lavage comprenant l'emploi d'eaux salines telles que l'eau de mer et d'un savon du type indiqué ci-dessus.
Toutefois, ces savons peuvent présenter l'inconvénient d'être hygrométriques et, par suite, de s'user prématurément. Pour éviter cet inconvénient, on additionne aux acides gras à faible poids molé- culaire utilisés pour la fabrication une certaine proportion d'acides gras à poids moléculaire plus élevé, par exemple des acides gras de ricin et lemélange ainsi obtenu est ensuite saponifié.
Les savons obtenus de cette façon se dissolvent et moussent suffisamment dans les eaux salines telles que l'eau de mer sans avoir l'inconvénient d'être hygrométriques et de s'user prématurément.
De plus, un tel savon est plus facile à préparer, à condi-

IMPROVEMENTS RELATING TO SOAPS AND
TO THEIR MANUFACTURING
The present invention relates to a process for manufacturing soaps intended for saline waters such as seawater; it also relates to products produced by this process.
The inventors have discovered that soaps prepared with low molecular weight fatty acids foamed in sea water; they therefore had the idea of using as raw material for the manufacture of soap, natural products with a high content of low molecular weight fatty acids, after having removed from these products the fatty acids with higher molecular weight.
Under these conditions, in accordance with the invention, a soap is produced from fatty substances composed mainly of acids @
<Desc / Clms Page number 2>
fatty low molecular weight, that is to say less than 210; these fatty substances comprising in particular lauric, capric, caproic, caprylic acids, can be obtained by removing, for example by distillation, the myristic, palmitic, stearic, oleic acids, etc .; it is also possible to start from natural fatty substances with a high content of lauric, capric, caproic or caprylic acids.
It is advantageous to make such a soap using oil extracted from Litsea Sebifera or from plants of similar families; this plant is found in Indochina where it is known under the name of BO I LO I NHOT or MONHOT,
In an exemplary embodiment, coconut oil is taken which is distilled so as to separate the fatty acids with a boiling point of between 125 and 176 degrees centigrade under a pressure of 10 millimeters of mercury. Then these fatty acids are saponified by passing them through a pipe to which is connected an inlet of soda mixed with potash; the mixing is carried out continuously inside the pipe and the saponification preferably continues in a container.
In another embodiment, the starting material is BO I LO I NHOT oil which is saponified without prior distillation.
The invention also covers the washing process comprising the use of saline water such as sea water and a soap of the type indicated above.
However, these soaps may have the drawback of being hygrometric and, consequently, of wearing out prematurely. In order to avoid this drawback, a certain proportion of fatty acids with a higher molecular weight, for example castor fatty acids, is added to the low molecular weight fatty acids used for the manufacture, and the mixture thus obtained is then saponified.
The soaps obtained in this way dissolve and foam sufficiently in saline waters such as sea water without having the disadvantage of being hygrometric and of wearing out prematurely.
In addition, such a soap is easier to prepare, provided

ture, store and handling does not require special precautions.
