The subject of fleece scouring or washing the wool while growing on the sheep, with a potash soap made on the spot with the waste tallow generally to be had on every sheep farm, seems recently to have been attracting attention in some quarters, and certainly would be a source of profit to sheep owners by putting their wool on the market in the best condition, and at the same time cleaning the skin of the sheep. It therefore appears to be a move in the right direction.
In concluding this series of articles on practical soap making from a consumer's point of view, the writer hopes that, although the subject has been somewhat imperfectly handled, owing to necessarily limited space and with many unavoidable interruptions, yet that they may have been found of some interest and assistance to consumers of soap who desire easily and readily to make a pure and unadulterated article for their own use.
COTTON SEED OIL.
By S.S. BRADFORD, Ph.G.
Having had occasion during the last six years to manufacture lead plaster in considerable quantities, it occurred to me that cotton seed oil might be used instead of olive oil, at less expense, and with as good results. The making of this plaster with cotton seed oil has been questioned, as, according to some authorities, the product is not of good consistence, and is apt to be soft, sticky, and dark colored; but in my experience such is not the case. If the U. S. P. process is followed in making this plaster, substituting for the olive oil cotton seed oil, and instead of one half-pint of boiling water one and one-half pint are added, the product obtained will be equally as good as that from olive oil. My results with this oil in making lead plaster led me to try it in making the different liniments of the Pharmacopoeia, with the following results:
Linimentum Ammoniæ.--This liniment, made with cotton seed oil, is of much better consistency than when made with olive oil. It is not so thick, will pour easily out of the bottle, and if the ammonia used is of proper strength, will make a perfect liniment.
Linimentum Calcis.--Cotton seed oil is not at all adapted to making this liniment. It does not readily saponify, separates quickly, and it is almost impossible to unite when separated.
Linimentum Camphoræ.--Cotton seed oil is far superior to olive oil in making this liniment, it being a much better solvent of camphor. It has not that disagreeable odor so commonly found in the liniment.
