DETERGENT.

I No Drawing.

5 of Michigan, have invented certain new and useful Im )rovenients in Detergents, of which the ollowingz is a specification.

This invention relates to detergents; and it comprises as a new detergent material an 1 intimate mixture of neutral soap-and mechanical wood pulp: all as more fully here- Jnalter set forth and as claimed.

[ungine grease. used lubricating oil and the like are virtually oily suspensions withv extremely fine. carbon, metal. etc, as the suspensoid; the dirt being, so to speak, colloided by the oil and being enclosed and protected thereby. In removing dirty greasy matter from the skin with soap and water the oil is converted into an emulsion and removed as such; and as it clings firmly, more or less frictionis' necessary to detach it from its wetting contact and substitute the soapy solution in its place. For this reason in making soapycompositions for removing greasy dirt, it is usual to employ a filler of a more or less granular material o1 some kind; usually Sand, kieselguhr or something of that sort having an" abrading function. An arbradant is used since thesurface-ct the skin is not smooth and it is necessary to reach the greaseinthe furrows. Su; 11 compositions however are disagreeable to use; and particularly it" the use he repeatedwithin short time intervals.

In the present invention I'ac'complish the result of detaching tlfe grease fromthefurrows and rugzosities of the skin by the use,

in conjunction with the soap, of an ex tremel fine, purified, wood fiber of the of that known as mechanical pulp and used for making lowgra-de paper. These fibers can be obtained fine enough to enter the tiny skin furrows and, so to speak, mop up the greasy matter so it will emulsify.

' while they are'too soft to have any of the objectioi' able abrading action. The pulp, moreover, has a wonderful emulsifying power of its own in promoting the suspension of .oil in soap solutions. Mechanical pulp is made by'presenting wood end-on .to a rapidly rotating grindstone in the presence of a flow otwater and the fibers so made Application filed May 31, 1921. Serial No. 473,823.

are not'sharp ended or slivery and are very fine. Moreover, most of the resins and glucosidep are thereby removed. ,Chemical pulps and sawdust do not have these desirable properties and are not adapted for the present purpose. Mechanical Wood pulp *fibers neither abrade nor pierce the skin.

I find that a mixture of a good neutral soap with a small proportion of mechanical wood pulp fibers quickly removes used lubricating oils and similar matters from theskin, without substantial abrasion or these woods the fiber is of such a character that it cannot-act in any way like a sliver.

In, connection with soap and Water the fibers act, so to speak, as a series of wash rags or towels which go into the irregularities of the skin and mop up the dirt.

Mechanical wood pulp may be used in connection with any of the usual soaps of the usual compositions provided they are free from included abradants, sawdust, etc. A formula which gives excellent results is made with 300 parts of run soap taken directly from the kettle, '800 parts of Water and 100 parts of mechanical wood pulp (best poplar .or aspen); .Suflicient dye or colorin}; matter may be used to give the desired color. Perfume may be used if desired.

hat I claim is 1. As a detergent, a composition substantially consisting of mechanical wood pulp and neutral soap rm from abradants.

2. As a detergent, a composition substantially'consis-ting of mechanical poplar Wood pulp and neutral soap free from abradants.

3. As a detergent,a composition substan- .tially consisting of 300 parts of run soap,

800 parts of water and 100 parts of wood n11. p1 In testimony whereof, I have hereunto affixed mysignature.
