Description

Patented Oct. 11,- 1932 UNITED STATES PATENT OFFICE mam meen'rr GRAY, or LARGHMONT, NEW YORK DETERGENT! Ho Drawing.

with water and cakes there; and tends to cling to the surface of the article to be cleaned I (marble, tile, terazzo, concrete) thus making it diflicult to remove such' volcanic ash from the container and from the article to be cleaned and also reducing the initial proportion of the abrasive to the chemicalconstituent.

I have found that finely ground soapstone, when added to such abrasive detergent. mixture, will prevent the close adhesion between the volcanic ash and any material with which it is brought into contact, and will cause it to settle with less compactness so that it may be more easily stirred back again into suspension in the water, and also permit the article to be cleaned to be more easily rinsed. Ihave found also that the presence of the soapstone reduces the severity of the abrasive action of the volcanic ash, and for some reason not clear to me, results in a more thorough emulsification of the oil, greaseorother fat prescut on the article to be cleaned.

The amount of soapstone to be added to the volcanic ash is preferably such as will I produce the possible optimum of the intended result without preventing the desired abrasive action of the ash. The degree of fineness of the volcanic ash is determined by the uses to which thedetergent is to be put, other things being equal the finer the ash the less harsh its abrasive action. I have found that the finer the soapstone particles the more effective is their action in preventing compacting of the volcanic ash. I prefer to use both soapstone and ash of a de ee of fineness which will permit passage tIi i'ough a 200 mesh screen. With the materials of Application filed January 8, 1929. Serial No. 330,148.

this degree of fineness, I prefer to use one part by weight of soapstone to two parts by weight of volcanic ash, although these proportions may obviously be varied within wide limits. v

A specific example of an improved detergent embodying my invention is the followng= a Parts Volcanic ash (200 mesh) 53 Soapstone (200 mesh) 27 Soda ash 4; Tri-sodium phosphate. 16

all the parts being by weight.

For the tri-sodium phosphate and soda ash I may substituteany other non-fatty detergent material suitable for use with a large proportion of Water.

In place. of volcanic ash I may use any other suitable abrasive material, for instance, comminuted pumice, quartz, or feldspar.

I do not claim to be the first to use volcanic ash or equivalent material as theabrasive ingredient of a detergent mixture, nor do I claim to be the'first to use "soapstone as such an ingredient. I am aware that it has been suggested to add to soapstone when used as a polishing material, a very small proportion of pumice as an abrasive ingredient-in connection with acid for-cleaning marble. My invention, however, is based upon the discovery that when soapstone and volcanic ash are mixed with a comparatively large amount of water, the ash will not compact as readily as when used without soapstone and will not cling to the container and to the article to be cleaned, as when used without soapstone, and that therefore both such container and such article can more readily be rinsed and the cleaning operation as a whole is facilitated.

I claim:

A composition of matter suitable for use as a detergent when admixed with water, consisting of 53 parts of volcanic ash, 27 partsof soapstone, 41- parts of soda ash and. 16 parts of trisodium phosphate.
