Claims. (01. eta-122) This invention relates toimprovements in soaps or creams which-are intended to produce a lather appropriate for shaving.
One of the purposes of shaving soaps or creams is to produce a lather or foam which is more suitable for shaving than are ordinary soap lathers. This lather must be abundant very fine, creamy, and firm. It must not be watery, yet it must quantity of 'water to permit it to remain moist for an appreciable length of time.
As for the cream or soap, itself, it must not become rancid or change in color when it is stored for a long period of time, and it should carry a gloss, commonly termed sheen, which gives it a pearly and glistening appearance.
Most important, this cream must not be harmful orv irritating to the skin. The ordinary shaving soaps used in the past are composed of a blend of commercial stearic acid soap and cocoanut oil soap, and a small quantity of free stearic acid. When creams are desired, glycerine and water are added. Since stearic acid soap produces astiif, heavy lather, but is differently soluble, while cocoanut oil soap produces a very soft and abundant lather andis readily soluble, the combination of the two soaps dissolves readily and makes a lather of the proper consistency. -The free stearic acid prevents excess alkalinity and produces the desirable sheen. The purpose of glycerine in a shaving cream is to soften the cream further to improve water solubility and to facilitate its extrusion from the tube-the customary packaging vehicle. The following is the average formula for such a cream:
Stearic acid soap Cocoanut oil soap 0'-. 13 Glycerine 1'1 Free stearic acid 3- Water N 35 and yet which is capable of producing the type of lather described in the preceding paragraphs.
Per cent be easily soluble and able to hold a large enough .Another objective of the present inventor is to product a shaving soap or cream, possessing the I desired characteristics, which will be stable in relation to the deteriorating efiects of ageing.
The present inventor has found that by using a major part of palmitic acid soap and a minor part of stearic acid soap and entirely omitting the cocoanut oil soap or similar soaps, a soap which produces the desired lather is obtained. The term, "major part of palmitic acid soap means that the proportion of palmitic acid is substantia lly in excess of the eutectic proportion ordinarily found in commercial stearic acid.
It is advisable that the ratio of the palmitic acid be not toohigh in order to obtain the maximum rate of lathering. The preferred ratio of palmiticto stearic acid soaps is 60 to BOpart-s palmitic acid soap to 40 to 20 parts stearic acid soap. A'70:3( l ratio represents the mixture, composed of these two soaps, which I consider most desirable for shaving soaps and creams.
The use of a 70:30 mixture of saponified, palmitic and stearic acids, instead of a saponified mixture of commercial stearic acid and cocoanut oil, is advantageous'in other ways. The lather of the soap, in which this ratio of acids is found, is fine and creamy and contains more water than do ordinary lathers; thus it "does not dry out on -the face as rapidly as do coarse lathers. Moreover, a suitable consistency 10f the cream as manufactured can be maintained even though less glycerin and more water'b'e used than are used in the present practice in making shaving creams, without danger of disassociation. The economy, in large-scale manufacture, of substituting water for glycerin is substantial. In order to prevent age from causing discoloration and rancidity, the soap or'cream should be relatively free from unsaturated fatty acids.
The following is' a suitable formula for a shaving cream which contains the preferred stearic-palmitic ratio:
. r v a Per cent stearic-palmitic soap Glycerin 10 Water 45 The soap may be potash soap, but a mixture of potash and soda soaps, 5 to 10 parts of potash to improve the "sheen."
The soap of the present invention can be manufactured either as a soap or, preferably, asa cream. If it is manufactured as a soap, it is moulded into a. shaving stick and packaged appropriately. If it is manufactured as a cream, it is softened with glycerin and water and packed in tubes,
Experimentation has proved that the soap or cream containing the specified palmitic-stearic mixture, glycerin, and water, as disclosed in this specification, produces a finer, richer lather', is more readily water soluble, and is capable of holding more Water than are previously known cocoanut oil shaving soaps and creams,-and, most important, it is absolutely harmless and non irritating to the skin.
Having described my invention, I claim:
1; A shaving composition containing soap of the class of sodium and potassium soap, which soap consists of substantially 60% to 80% -by weight of saponified palmitic acid and 40% to by weight of saponified stearic acid, the said shaving composition being devoid of cpcoanut oil soaps ,and being characterized by its latherability and by the stability of the lather produced from it.
2. A shaving composition containing soap of the class consisting of sodium and potassium soaps, the said soap portion comprising, substantially 60% to 80% by weight of saponified palmitic acid and 40% to 20% by weight of saponified stearic acid, the said composition additionally containing glycerin, and water in quantity substantially equal to the soap content.
3. A shaving composition, the saponaceous portion of which comprises substantially 60% to 80% by weight of saponified palmitic acid and to 20% by weight of a saponified stearic acid, said saponified palmitic acid and saponified stearic acid being soaps of the class consisting of sodium and potassium soaps, with from approximately 5 to 10 parts by weight of potassium soap being present in said saponaceous portion to each one part by weight of sodium soap.
4. A shaving cream, the saponaceous portion of which comprises substantially to 80% by weight of saponified palmitic acid and 40% to 20% by weight of saponified stearic acid, the said saponified palmitic and saponified stearic acids being soaps of the class consisting of sodium and potassium soaps, with the potassium soap constituting from 5 to 10 parts by. weight of the saponaceous portion to each one part by weight of sodium soap, the said shaving cream additionally comprising glycerin and water.
5. A shaving cream comprising approximately 45% by weight of soap, 45% by weight of water, and 10% by weight of glycerin, the said soap being a soap of the class consisting of sodium and potassium soaps and being made up of saponified stearic acid and saponified palmitic acid, with 5 to 10 parts by weight of potassium soap being present .in the'soap component to each one part of sodium soap, and with of the soap being palmitic acid soap and 30% being stearic acid soap.
