ceous shaving preparations, respectively, inaccordance with the invention are remarkable for their excellent lathering power.

Razors readily produce cuts of the skin and consequently causebleeding. With a view to stop ping said bleeding, in accordance with the present invention there are added to the shaving soaps or saponaceous shaving preparations, respectively, styptic or hemostatic substances.

A number of substances promoting the coagulation of blood are known per se. These substances, however, are not readily suitable as an addition to shaving soaps. In selecting styptic or hemostatic substances which are to be added to shaving soaps, care must be taken that they do not impair the lathering power of said shaving soaps.

This invention then has as an object new shaving soaps or saponaceous shaving preparations, respectively, and methods for their production. A further object is shaving soaps or saponaceous shaving preparations, respectively, possessing excellent lathering power. A still further object is shaving soaps or saponaceous shaving preparations, respectively, containing an addition of styptic or hemostatic substances which will not impair the said lathering power. 7

We have. found that the lipoid soluble substances from soybeans contain agents which act as styptics or hemostatics. The term lipoid soluble substances" is used in the present specification and claims to mean substances which are soluble in the usual solvents for fats, such as ether. The aforementioned lipoid soluble substances from soybeans contain, in addition to compounds acting as styptics or hemostatics, other compounds which are extensively inactive in this respect. Therefore, it is unsuitable to add to the shaving soaps the lipoid soluble substances from soybeans as a. whole, particularly in view of the fact that an excessive amount of lipoid soluble substances from soybeans will unfavourably affect the lathering power of the shaving soap or saponaceous shaving preparations, respectively.

By fractionating the lipoid soluble substances from soybeans we obtain. products which possess considerably increased stypticor hemostatic properties. according to the invention fractionation is effected by treating the said substances with selective solvents. In certain cases, by adding another solvent to the solution of ali the lipoid soluble constituents of soybeans, there he precipitated the less active components. On other hand, fractionation may proceed in the re verse order, i. e., by adding another solvent will be precipitated the styptic or hemostatic substances, while the less active components remain in solution. By adding, e. g., ethyl alcohol to a petroleum ether solution of the lipoid soluble substances from soybeans, there will be precipitated the less active components. 0n. the other hand, by adding acetone to a solution of the lipoid soluble substances from soybeans in ether, petrol, or benzene, precipitation of the styptic or hemostatic substances will be effected.

Fractionation may be carried'out repeatedly if desired, e. g., in such away that thelast mentioned precipitate obtained by adding acetone to ethereal solutions is redissolved in ether and again precipitated with acetone or alcohol.

The concentration of the styptic or hemostatic substances is checked by physiological tests. Fractionation is continued until a. preparation is obtained, .1 cc. of a 1% solution of which will coagulate 1 cc. of rabbit blood which has previously been. admixed with hirudin in the ratio 127500, after one hour. Hirudin blood without addition of the lipoid fraction will coagulate after 48 hours.

The new shaving soaps or saponaceous shaving preparations, respectively, according to the present invention containfrom about 3 to 10% of, the styptic or hemostatic substances obtained from soybeans. An addition of 5% has proved particularly advantageous. These styptic or he- -mostatic substances when added to shaving soaps, without impairing their lathering power, will cause bleeding from small cuts to stop immediately.

Another embodiment of the invention consists in adding to the shaving soaps or saponaceous shaving preparations, respectively, the, styptic or hemostatic substances in the form of adsorption compounds upon carriers, such as calcium carbonate, aluminium oxide, or silica.

These adsorption compounds are obtained by stirring aqueous emulsions, or solutions in organic solvents, of the styptic or hemostatic substances with the said adsorbents, and removing the supernatant liquid as soon as adsorption is complete. As a rule, 2' parts of adsorbent will be used for 1 part of the styptic or hemostatic 'substances. The adsorption compounds show a considerably increased activity, as compared with the'parent material. Although the active substance amounts to one third only of the adsorption compounds, in most cases it will be suflicient to add to the soap 340% of said adsorption compound.

the shaving soaps in accordance with the present invention to contain, in addition, certain amounts of free organic acids. These acids will effect a considerable more intimate combination of the I lipoid soluble substances with the soap mass and, in the case of cream-like products, will prevent separation of the watery constituents. In thisconnection, high molecular fatty acids such as stearic and palmitic acid, and/or aliphatic hydroxy acids such as citric, tartaric, or lactic acid,

may be employed.

Similarly, it is an advantage to add to the shavlug soaps or saponaceous shaving preparations, respectively, according to the invention mucous substances such as tragacanth, and particularly pectin substances which may be obtained, e. g. from unripe fruits.

Preparations which, in lieu of soaps, contain soap-like products, such as the alkali metal sulfates or sulfonates of high molecular fatty alcohols come likewise within the scope of the present invention. As an example of this type of compounds, sodium lauryl sulfonate may be cited.

The shaving soaps or saponaceous shaving preparations, respectively, according to the invention, may contain all the various admixtures mentioned above, alone as well'as in combination. Our invention is illustrated but not limited by the following examples. 80 The fractionating of the lipoid soluble substances can be illustrated as follows:

Example I 100 kg. of soybeans were broken up by means of a crusher and extracted with petroleum ether until exhausted. By concentrating the petroleum ether solution to a strength of 20%, there were obtained 80 litres of this extract. Four times the amount of acetone was added thereto and the 4 whole was subjected to centrifugation. After removal of the solvent the precipitate amounted to 1.7 kg. It was redissolved in 8 litresof petroleum ether and precipitated with 20 litres of alcohol. There were obtained .8 kg. of a-substance soluble in alcohol, and .9 kg. of a substance insoluble in alcohoh The amounts of styptic or hemostat'ic substances contained in the various fractions were determined by means of the following coagulation tests:

Coazulated alter M A. Subdcncc soluble in acetone .1 cc. of 17 ageous solution +1.0 cc. of rabbit blood with irudin 1:1500 10 hours. .1 cc. of 7, a ucous solution +1.0 cc. of rabbit blood th irudin 1:7500 No reaction after 10 hours.

These tests show that the substance soluble in alcohol is the most eflective agent in promoting coagulation.

An example of the preparation of the adsorption compound upon aluminium oxide is as follows:

The following example illustrates the preparation of the adsorption compound upon calcium carbonate:

Example III 25 g. of the'alcohol soluble fraction in accordance with Example I were colloidally dispersed n 100 cc. of water and admixed with g. of calcium carbonate. The adsorption product was separated from the aqueous solution by centrifugation, and dried. When subjected to thecoagulation test it gave results which were in concordance with those of Example II.

The following example illustrates the preparation of the adsorption compoundupon silica:

Example IV 25 g. of the alcohol soluble fraction in accordance with Example I were colloidally dispersed in 100 cc. of water and admixed with '75 g. of silica. The adsorption product was separated from the liquid by centrifugation, and dried. When subcoagulation test it gave results which were in concordance with those of Example II.

As a practical illustration of the production of shaving preparations in accordance with the present invention the following examples, in which the parts are by weight, are given:

Example V together 5 parts of the lipoid fraction obtained in accordance with Example I, and the mixture was added to the saponification mass. The product thus obtained can be worked up to form shaving sticks. Upon addition of 50 parts of water a cream-like product will be obtained theref,

Example VI parts of stearic acid, 10 parts of cocoanut oil fatty acid were saponified by means of 20.6 parts of KOH in 34 parts of mo and exactly neutralized. In the meantime there were melted together 5 parts of stearic acid lipoid adsorption product according to Example II, and the mixture was added to the saponlflca obtained can be worked up to form shaving sticks. Upon addition of 50 parts of water obtained therefrom.

Example VII 92 parts of potassium lauryl sulfate containinr a minimum of electrolytes, 27 parts of cetyl aloe-- and 10 parts of the acream-like product will be hol, and 1 part of lactic acid, were admixed with 100 parts of water. To this mixture there was added, while heating, a mixture comprising parts of the lipoid adsorption product according to Example IV and 5 parts of stcaric acid, until a product of paste-like consistency was formed.

Example VH1 90 parts of stearic acid, parts of cocoanut oil fatty acid were saponified by means of 20.6 parts KOH (dissolved in 34 parts of water), and exactly neutralized. To this mixture there were added 10 parts of the lipoid adsorption produ t according to Example 111 which had previously been melted together with 5- parts of stearic acid. Finally, 100 parts of a 2% paste of tragacanth. pectin, or other vegetable mucous substances were added to the mass.

We employ the word hemostatic in the appended claims to include agents which possess hemostatic or styptic qualities. term saponaceous used to include soap-like material, whether a true soap or another chemical compound having suitable lathering properties. In setting forth particular ingredients of the improved shaving preparations and particular quantities or proportions thereof we recognize that wide variations may be made without sacrificing advantages of our invention, and we therefore desire that the claims be accorded a scope fully commensurate with the spirit of the invention and its departure from the prior art.
