' Soap making is well known, and comprises saponifying a fat and/or an oil with an alkali metal hydroxide or other basic inorganic material. While there has been substantial literature describing soap making, nevertheless soap making is still essentially empirical, with ad vances made in the art on a trial and error basis. As in the .case of many complex admixtures, the addition of a new ingredient to a soap, while solving one problem, often gives rise to new problems, thereby creating the need for yet further additives. Since soaps must compete with detergents, it is essential that the soap do more than just remove dirt; it must also be capable of washing the clothes to get them as white and bright as the detergents. That is, the soap must not dull the colors of the clothes and other material being washed. Thus far, it has been difficult to provide a soap of simplified formulation that can be used with advantage in automatic washing machines,
It is an object of the invention to provide a novel and improved soap.
It is a further object of the invention to provide a soap powder than can be used to advantage in automatic washing machines,
It is a further object of the invention to provide a soap powder that gives a clean and bright wash when used in an automatic washing machine.
These objects are fulfilled by the present invention, which provides a soap powder consisting essentially of sodium hydroxide, lard, sodium tetraborate and coconut oil.
The present invention also provides a process for making the soap powder, which consists essentially of forming an aqueous solution of sodium hydroxide, dissolving lard in the solution while heating and stirring, dissolving sodium tetraborate and coconut oil in the solution while continuing the heating, heating the mixture for a period of about 2 to about 6 hours to saponify the mixture, allowing the saponifying mixture to cool to room temperature and to stand for a period of from 2 to 4 days, and crushing the dried soap into powder.
The soap of the present invention is thus a mixture of only four active ingredients, instead of the complex mixtures previously encountered in the art. Because of the high quality of the ingredients, a high quality soap is formed without the need for a large number of additives.
A preferred recipe is as follows:
sodium hydroxide 10-16 Ounces water 2-4 quarts lard 80-105 ounces sodium tetraborate 8-30 ounces coconut oil 1-5 ounces Because of the empirical nature of soap, the four active ingredients set forth above (i.e. excluding the water) are essential. For example, substitution of lard with beef tallow results in a soap of not as high purity. The use of oils other than coconut oil have proved to be unsuccessful. Omission of the sodium tetraborate results in too harsh a soap. The use of larger quantities of coconut oil results in a disagreeable oily feel to the soap and leaves an oily film on the wash. v i
To obtain the finest soap according to the invention, it is necessary to use the best quality ingredients. Thus, the lard should be as pure as possible, white and nearly odorless and tasteless. The coconut oil should likewise be as pure as possible, the best variety of coconut oil being Cochin China oil.
The soap of the present invention is white and has an agreeable odor. If desired, however. perfumes and/or coloring agents may be added.
If the soap is to be colored, then it is preferred to add between about l8 and about l 19 grams of coloring agent per lOO pounds of soap. the amount of color to be used depending upon the desired shade and the strength of the coloring agent used. The coloring agent may be addedas an aqueous solution along with the coconut oil.
Perfume, if used, is also added along with the coconut oil. Any perfume used in soaps may be used in the soap of the present invention, such as a perfume oil formed by admixing 5 ounces of geranium oil, 1 ounce of clove oil and 1 ounce of musk ketone. The perfume oil thus formed must stand for at least 1 week before use.
The following Example illustrates a preferred embodiment of the invention.
EXAMPLE A large pot was charged with 3 quarts of water, to which was slowly added 13 ounces of commercial lye (96 percent sodium hydroxide, 2 percent sodium carbonate, 2 percent inerts, all by weight). The mixture was stirred to dissolve the sodium hydroxide and form a solution. The solution was then heated over a low flame and 6 pounds of lard was added, while stirring. The heating and stirring was continued until the lard was fully dissolved, and then 24 ounces of sodium tetraborate and 3 ounces of coconut oil were added. The mixture thus formed was heated over a low flame, with stirring, for four hours, to assist in the saponification. The glycerine formed during the saponification was not removed, but rather was allowed to remain in the soap.
At the end of four hours, the heating was discontinued and the soap allowed to cool to room temperature and to stand at room temperature for three days, after which it was crushed into small particles.
The soap powder was then tested in top-loading automatic washing machines using one cup of soap powder per l6-pound load. Dirt was thoroughly removed from both white and colored clothes, and a distinct softness of the washed material was noted. The wash was clean and bright.
What is claimed is:
