UNITED STATES ABRAHAM E. 'LINDY, O]? WEBSTER, MASSACHUSETTS.
This invention relates to a hand soap particularly designed for removing oils or greases. Such soaps are largely used by painters, mechanics, garage men, electric ans and other workmen, and are of great utility for any person Whose hands are soiled by paint or grease.
It is the general object of my invention to provide a hand soap of a new and im proved composition, which is particularly effective and satisfactory for the purposes defined.
Many such soaps contain a sand-like or gritty substance which is eifectlve in dislodging dirt or grease, but which has a tendency to irritate the skin.
Accordingly, it is a further ob ect of my invention to provide a hand soap in which all such sand-like or grltty substances are.
omitted or replaced by other substances, without impairing the effectiveness of the composition.
The invention further relates more specifically to the provision of a hand soap of the novel and improved composition which will be hereinafter described and more particularly pointed out in the appended claims.
\Vhile the proportions of the several substances in my improved soap may be varied more or less without seriously altering the effectiveness of the compound,'I find that a satisfactory formula for my improved soap is substantially as follows:
- Per cent. Soap (preferably in the form of dry chips) 110 Calcium carbonate precipitate 10 Soda ash or sodium carbonate 3 Very fine wood saw-dust 2% Sassafras or other perfume 8 Water 73% It will be understood that the Sassafras or other perfume is provided merely for givin a pleasant odor to the compound and that it has no particular functmn as a cleansing element.
Application man 27, 1926. Serial n. 112,143.
The fine saw-dust gives body to the composition and also has a scouring efi'ect similar to the gritty substances previously employed, but without producing any irritating effect upon the skin. The composition, when carefully made and having its parts thoroughly mixed and commingled, forms a thick paste, which if put up in tin boxes,
will retain its moisture for a long time and IZvill not become hardened or caked in the The soda-ash and calcium carbonate cooperate with the soap chips in producing an effective cleaning compound and in loosening and removing such substances'a s paint, grease or oil.
The hand soap composition above described inay be easily manufactured at a reasonable cost and may be used indefinitely Without injurious effects to the skin.
As previously stated, the exact proportions' given in the formula may be substantially varied Without destroying the efliciency of the soap in many respects. Accordlngly, do not Wish to be limited to the exact details and proportions herein disclosed, otherwise than as set forth in the seventy-three and half percent of a mixture of water and perfume.
In testimony whereof I have hereunto aflixed my signature.
