SHAVING PREPARATION 1W0 Drawing. Application filed May 12,

This invention relates to new and improved shaving preparations which contain a styptic in regulated amount incorporated therein.

In my prior application Serial No. 625,414, 5 filed March 15, 1923, I have describedand claimed certain new soap preparations con taining phenol-esters of higher fatty acids containing more than eleven carbon atoms in the fatty acid molecule.

The present invention relates to improved shaving preparations which are free from such phenol-esters of higher fatty acids, but which nevertheless contain a small and regulated amount of a styptic incorporated therein.

The shaving preparations of the present invention may be shaving soaps or shaving soap preparations containlng mainly soap as their basis or they may be other preparations containing only small amounts of soap or free from soap and containing other shaving ingredients. In addition to such usual shaving soap or shaving preparation ingredients I incorporate a small amount of a styptic, such as adrenalin, or other styptic, and I regulate, the amount of adrenalin so that it, will impart to the shaving preparation a mild astringent or styptic action which will be sufficient to prevent or stop bleeding, which may be caused accidentally by a cut or by injury 30 to a sensitive skin. A small amount of adrenalin is sufficient for this purpose, although other styptic materials may be similarly used in small and regulated amount.

The styptic should be compatible with the ingredients of the shaving preparations, that, is, it should not react obj ectionably with them to interfere with the desired action of the preparation, or of the styptic.

Adrenalin can be used in various forms, both natural or synthetic, such as in the form of its salts with either inorganic or organic acids, including salts with fatty acids, which will readily blend with the other ingredients of the shaving preparation.

Salts such as the hydrochloride, borate, benzoate, or salts with fatty acids may be used. In case the soap has apronounced alkaline reaction, this can be overcome, if objectionable, by the incorporation of alkali-neutralizf 60 ing ingredients in the preparation; or any 1926. Serial No. 108,694.

objectionable excess of alkali can be avoided in the manufacture of the shaving preparation. The adrenalin compounds incorporated with the preparation may react to a greater or less extent with certain of the ingredients of the shaving preparation, provi ded the reaction products also posses the desired styptic effect.

In addition to the styptic there may also be incorporated with the shaving preparation antiseptics or other ingredients, including phenolic compounds other than the higher phenol-esters heretofore referred to. Compounds such as lysol or other phenols or phenolic compounds, metacresol acetate, parachlor-metzncresyl acetate, or other medicinal or antiseptic. preparations can be used.

A convenient method of incorporating the adrenalin is inthe form of an aqueous solution, e. a solutioncontaining 1 part adrcnalin to 1,000 parts of water, although a more concentrated solution can be used as well as a solution in some other solvent. Such a solution may be incorporated into the shaving cream, for example, in the proportions of 1 to 5 grams or centimeters of the solution per ounce of shaving cream. a

While variousshaving preparations may be made in various forms, I consider a shaving cream including the styptic as a particularly advantageous form of preparation.

In referring to a shaving preparation free from phenol-esters of higher fatty acids, I, exclude such esters as are claimed in my companion application heretofore referred to,

1. e., phenol-esters of fatty acids containing more than eleven carbon atoms.

Instead of adrenalin other 7 suitable astrlngents or styptics can be used whlch are compatible with the ingredients of the shaving' preparation, or other styptics or astringents canbe used in addition to the adrenalin, etc., for example, tannin or tannin derivatives.

Adrenalin when used may be used in various forms, including both natural and synthetic adrenalin products and including not only adrenalin itself, but adrenalin derivatives ofvarious kinds, or mixtures of adrenalin or combinations of adrenalin with various other substances which do not interfere with the desired styptic action. Other ingredients such as perfumes, coloring material, antiseptics etc. can be added. Also, preservatives or anti-oxidizing ingredients can be added to prevent objectionable oxidation or to improve the keeping qualities. When the shaving preparation is a cream it can be kept in tubes which protect it from oxidation and this is particularly advan tageous with a styptic material which is liable to undergo oxidation unless preserved in some such way. a

I claim:

1. A shaving preparation free from phenol esters of higher fatty acids, and comprising a saponaceous' material and 'an organic styptic compatible therewith.

2. A shaving preparation free from phenolesters of higher fatty acids, and comprising a saponaceous material andadrenalin.

3. A shavlng cream free from phenolesters of higher fatty acids and containing adrenalin.

In testimony whereof I afiix my signature.
