HAND WASHING POWDER.

N0 Drawing.

This invention relates to detergents in eneral and particularly to the kind adapted 'or cleansing parts of the body and soiled parts of apparel.

The prime object of my invention is to provide a detergent which will readily emulsify with greases or oils and remove other kind of dirt, the moment not only warm, but cold water is mixed with the detergent.

A further object of my invention is to provide a detergent which will dissolve paint and remove same from skin and fabrics, while leaving both skin and fabric soft and smooth.

I am aware of many kinds of washing or cleansing compounds having abrasing functions caused by the mixture therewith of sand, kieselguhr, pulverized stone, etc, which abrasives however, are detrimental, and sometimes even injurious.

My invention combines the good qualities of a detergent without being injurious to either skin or fabric. Primarily, my detergent, comprises in its finished form a relatively dry powder which will readily, but invisibly, emulsify grease or oily substances.

It contains a mild mineral combined with an absorbent vegetable abrasive, which latter, performs the function of a carrier for the mild mineral abrasive, and at the same time, serves in a similar capacity to that of a sponge. The two combined abrasives are particularly useful in reaching the furrows of the skin, and particularly of the hand, which furrows are diiii cult to reach by a soap emulsion itself. The abrasives, so to speak, wipe clean the furrows of the skin.

I accomplish the foregoing objects and results by compounding finely ground dry wood pulp with sodium carbonate, NaflO lOH O, commonly known as sal soda, non-acetic or neutral. fat as for instance petrolatum, green, soft, alkaline or potash soap, finely pulverized pumice, and varnish made of resinous matter dissolved in oil of turpentine (G H preferably a turpentine varnish. The last mentioned ingredient serves not only for the purpose of dissolving Application filed July 5, 1927. Serial No. 203,684.

and breaking up of paints of like impurities, but also performs the function of a binder for the above composition because of its resinous matter dissolved in the turpentine. The best results I have obtained by compounding the followingquantities of the above mentioned substances:

Fifteen parts of finely ground dry wood pulp, twelve parts of sal soda, three parts of non-acetic or neutral fat (petrolatum), seven parts of green, soft or potash soap, one and one-half parts of finely ground pumice powder, one part of turpentine varnish.

l first combine the S211 soda, the fat, and the green soap, forming an intimate mixture of these constituents, then T admix pumice powder and gradually add wood pulp until the latter aborbs the pasty mixture which eventually assumes the form of a powder. I then add turpentine varnish to the combined ingredients and thoroughly mix the composition.

in use, it is preferable to wet the skin or the material to be cleansed. Then a half teaspoonful of my compound is sprinkled upon the wettcd surface and rubbed in thoroughly. Thereafter, the cleansed surface is rinsed with water, nomatter whether warm or cold.

It will be observed, that the emulsion talcing place between the grease on the hand and my detergent, is not visible. Nevertheless, all grease and even paint removed and the hands are smooth and soft after rinsing.

The coloring of my detergent depends upon the coloring of the wood pulp mostly, but artificial coloring may be added without injury to the product, or perfumes may be combined therewith, if desired.

l/Vhile I have mentioned particular quantities of the different ingredients used, be it understood that deviations may be made without departing from the broad scope of my invention, for which I claim:

1. A detergent in powder form, consisting of a mixture of fifteen parts of dry finely ground wood pulp, twelve parts of sa l soda1 three parts of neutral fat, seven parts of green soap, one and one-half parts of finely pulverized pumice, and one part of turpentine varnish.

2. A detergent in powder form, composed of fifteen parts of finely ground dry Wood pulp, twelve parts of sal soda, three parts of petrolatuni, seven parts of soft soap, one

7 and one-half parts of finely ground pumice powder and one part of turpentine varnish composed of oil of turpentine as a solvent 1 and resinous matter. 7
