COMPOUND FOR PROTECTING TIIE HANDS FROM THE EFFECTS OF CONTACT WITH OIL, GREASE, 'AND DIRTY SUBSTANCES.

No Drawing.

To all whom it may concern:

Be it known that I, DAvn) R. KELLoeo,

a citizen of the United States, and a resident of the borough of Edgewood, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in a Compound for Protecting the Hands from the Effects of Contact with Oil, Grease, and Dirty Substances, of which the following is a specification.

It is a common experience with all those who have to subject their hands to contact with oil, grease, rime and dirt in general, that the pores 0 their skin soon become filled with particles which are very difiicult, if not actually impossible, to remove without serious injury to the skin. Such particles greatly disfigure the hands. 'This experience is frequently had by the motorist who finds it necessary to make some adjustment or repair to his motor.

It is the object of my invention to supply a means for minimizing the labor of removing su'ch foreign substances from the skin upon the completion of such work. It is essential that such result be accomplished without injury to the skin of the user. In employing the material of my invention, which will be described more fully herein,

the hands are first covered with athin layer which is then rubbed well into the cracks and pores of the skin and'under and around the nails. It is thn allowed to dry, which action takes place in a few moments, and then the hands can be used in oily dirty work without this foreign matter working into the openings of the skin. My new compound is insoluble in oils and greases and, by scaling up the cracks and-pores, prevents the oil, grease and dirty particles from reaching those parts. It is characteristic of my compound that when it has dried on the hands the user is scarcely conscious of its being there and no inconvenience is experienced from it in doing even the most delicate work.

While I am aware that other preparations have been used to obtain the same object as that of my invention, these have proven defective in one or more of the following respects:-

(1) Failure to keep the oil and dirt from reaching the cracks and pores.

Application filed January 3, 1924: Serial no. cisaisn' (2) I nj urious to the skin and Y (3) Make the hands unsuitablefor doing the work, i. e., too sticky or oily.

I have found'that a mixture of clay, such as bentonite, which forms a gelatinous mixture with water, when mixed in proper proportion with a mild soap, such as Ivory soap, and water, forms a paste which can be applied to the hands in the manner above described and which, when dried, protects against the effect of contact with oil, grease and grime. When the hands are so treated they can be exposed to contact with oils, greases and other dirty foreign matter without damage to the skin, as all of the pores a'ndcracks are thoroughly filled and these foreign matters prevented from lodging-in these openings. When theuser has completed the dirty work the entire substance, i. e., the paste and the foreign matter can 'be washed off in water, generally without the use of any soap other than that contained in the paste.

As will be apparent to those skilled in this art this material will not injure the skin.

The proportions that I have found best are bentonite 17%, Ivory soap L and distilled water 78%%. I have generally pre ferred to add some odorous material to make the use of the compound still more pleasant. For this purpose I have found an extremely small amount of oil of peppermint or sassafras very satisfactory.

I have found it best in preparing my new compound to make separate mixtures of- (a) Bentonite and water and (b) Soap and water.

*Thesetwo mixtures are allowed to age for a period of'at least 24 hours so as to insure a thorough penetration of the water. The two pastes then formed can then be mixed and the perfuming element added. The proportions employed in each of the separate mixtures, when a paste having the consistency of that described above is desired, are bentonite 21%, water 79%, Ivory soap flakes 23.1%, hot water 76.9%. Each of these should be thoroughly stirred to insure complete mixture. The compounding-of these two pastes to give the final product is in the proportion of 80.7% of the bentonite paste and 19.3% of the soap paste. After this mixture has been made the perfuming element is added in sufiicient amount to give the desired strength of scent.

It will be found that the paste will be too fluid and will not dry to a condition which will make its presence, on the hands of the user, unnoticed, if more than 80% of Water or more than 12% of soap, or less than 10% of bentonite, is used. Again it will be found to be much less effective, being too dry and not adherent, if less than 75% of Water, or

2%% of soap or more than 20% of bentonite is employed. I

While the proportions given above are the preferred ones and while the materials mentioned are the ones found most suitable by me, it is not to be understood that my invention is limited to the use of them as both the proportions and the materials may be varied in ways well known to those skilled in the art without departing from the novel features of my invention. 1

What I claim is:

1. A compound for protecting the skin from the effects of contact with oil, grease and dirty substances consisting of a mixture of gelatinous forming clay, pure soap and water.

2. A compound for protecting the skinv a mild soap and water in proportions within the following limits :Bentonite 10 to 20%, soap 2 to 12%, water 75 to 85%.

5. A compound consisting of a mixture made up of 17 bentonite, 4.5% soap and 78.5% water.

In testimony whereof, I sign my name.

DAVID R. KELLOGG.
