Patented Feb. 13, 1934 SHAVING SOAP Victor Scheffer, Budapest, Hungary No Drawing.
Application January 26,
Serial No. 511,433, and in Hungary January 1 Claim.
The base of shaving soaps or creams consists of alkali and more especially of potash-soaps or a mixture of potash-and soda soaps owing to their forming a lasting lather. It has been also proposed to use shaving creams containing ammonia soap, especially a cream consisting of ammonium stearate and a high percentage of Water, but with these only a weak lather can be obtained. Besides, all these soaps require a comparatively long lathering and rubbing and even then their effect is.-especially with a strong beard growth-not very satisfactory.
My invention is based on the observation, that alkali soap reacts with ammonia soap in the presence of a sufiicient quantity of water in liberating ammonia, and if the alkali and ammonia soaps are brought into contact with the quantity of water sufficient for the said reaction under circumstances, that is to say on the skin surface to be shaved, that the reaction takes place on the skin itself during lather with a brush, a very slippery though not very rich lather is formed, which possibilitates after comparatively short lathering a perfect and exceeding easy shaving-even with very hard beards and not very keen razor blades-leaving the skin soft and smooth without aching or burning feeling.
The shaving soap according to my invention must contain only low percentage of water, insufiicient to induce the reaction between the alkali and ammonia soaps. For this purpose the percentage of water must be low enough to leave the soap solid and not to form a cream. Besides the percentage of the alkali soap must exceed that one of the ammonia soap but must not be more than the quadruple thereof. It may be understood, that ammonia soaps are subject, even with a very low content of water, even if no alkali soaps are present, to a successive decomposition, but this decomposition is-if the soap is dry enough-so slow, that the durability of the soap is sufiicient for practical purposes. The decomposition can be effectivemonia, such as of tin foil or by enclosing the soap in a tight receptacle.
In order to obtain a mixture of alkali and am monia soaps with the required low water content, the alkali and ammonia soaps are prepared separately and mixed with each other in solid state. This mixing can be effected either by mixing both soaps in dry and pulverized state and by pressing the mixture to sticks or blocks, or by kneading the one of the two soaps, preterably the pulverized ammonia soap into the other soap rendered plastic.
If both soaps can be rendered plastic even with the required low water content, they can be mixed directly.
preferred.
In preparing the ammonium stearate an excess of ammonia should be used. Good results have been obtained by the saponification of 100 g. stearine with 20-25 g. of concentrated ammonia solution. The solid ammonium stearate is finely ground and mixed in the proportion 1: 3 with a solid shaving soap of good quality rendered plastic.
According to another method a fatty acid may be dissolved in ammonia whereupon the solid soap is separated by means of potassiumchloride from the liquid. The separated soap contains still a high percentage of ammonia soap. The salting must be conducted only so far, that the mixture 20% of ammonia soap.
In the claim the term substantially anhy contains not less than drous means that the soap may contain water but the quantity of water is so small that the soap is solid and no decomposition of the am;- monia soap by hydrolytic action of the solution of alkali metal soap may be produced.
What I claim is:
A shaving composition consisting of ammonium stearate and sodium soap, the percentage of sodium soap exceedingv the percentage of ammonium stearate but not exceeding the quadruple and the composition being substantially anhydrous.
