WASHING COMPOUND.

. pound formed of a minimum number of ingredients most effective for the cleaning of clothes, especially for the removal of grease and stains therefrom. I

Another object concerns the provision of means whereby clothes can be thoroughly cleaned, sterilized and bleached in one continuous, simple process involving in general merely placing the clothes in a solution and, under some conditions, applying a moderate degree of heat.

In general, the invention comprises a washing compound which can be easily mixed and when dissolved in water at ordinary or moderate temperatures will thor oughly effect the cleansing in the manner above referred to when the clothing is placed therein.

This compound in general includes three general types of ingredients. One ingredient accomplishes the sterilizing of the goods; another, acts as a detergent or scouring agent to release the dirt from the clothing; and the third, acts in the manner of a soap or an emulsifier to carry oil the dirt.

As a general rule I prefer to use an oxygen yielding salt for the bleaching and sterilizing agent preferably one in which the oxygen is held in a dorment state until the compound is placed in water; to use an alkali detergent for the scouring agent; and to use a soap for the emulsifier.

More specifically, I prefer to use a sodium oxygen yielding salt, of which class sodium perborateand sodium percarbonate are examples. I prefer to use an alkali detergent toefl'ect the scouring action, an example of this type of ingredient being spfdlugmgie As an example 0 the soap, I Prefer to use alhi lgrfl li P f erably, to use it in the form 0 e flakes so that it will quickly and easily become thoroughly mixed with the other ingredients.

To produce the proper combination between the soap and the other ingredients, I prefer to use a neutral soap, that is, a soap containin no free alkali and which is sliced and dehy rated to as high a degree as possible or until it crumples into small flakes, and

when in such form is mixed with a compound bearing available oxygen in powdered form. The main reason for employing a dehydrated soap in flake form in combination with the powdered oxygen-bearing compound is so that when the mixture is packed it will not lose its available oxygen norform any gas or adhere to the walls of the container, which has been proved by experiment to be the case where soap and oxygen-bearing compounds were both in powdered form.

More specifically, a preferred example of my compound comprises sp diung per bpra te, sgdiant asiiz nhesnlnte' and anhydrous.

soap, respectively in the proportions of 25 parts to 10 parts to 65 parts. These ingredients in these general proportions arepreferably mixed together and sold in desired quantities. The compound can be used by dissolving any desired quantity of it in water and then placing the clothes to be cleaned therein. The cleansing action can take place very quickly under the influence of heat applied to the container, or more slowly over a longer period of time in cold water. action of water on the sodium perborate achieves the release of oxygen from said composition, and it is this oxygen released in intimate association with the clothes which causes the sterilizing and bleaching action to take place. The sodium tribasic phosphate acts as a detergent to clean, scour and release thedirt from the goods. Itjs, of course, understood that other ingredients may be used astliis 'det'ergenh for instance, sodium car;

bonate.

What I claim is 1. A laundry washing compound composed of material adapted to be poured from its package into the washing water in loose granular form and including a major proportion of a solid oxygen bearing sterilizing and bleaching salt and anhydrous soap thoroughly mixed with said sterilizing and bleaching salt, said anhydrous soap being dehydrated to a high degree so that it is inv crumpled flake form.

2. A laundry washing compound adapted to be poured from its package into the washing water in loose granular form and composed of an alkaline salt, a solid oxygen bearing sterilizing and bleaching salt and an hyyrous soap dehydrated to a high degree so that it is in crumpled flake form.

3. A laundry washing compound adapted bearing sterilizing and bleaching salt and anhydrous soap dehydrated so as to be crumpled into small flakes, said sterilizing 15 and bleaching salt and said soap being in the form of small particles throughout said compound.

5. A powdered washing compound, which includes approximately twenty-five parts of 20 sodium perborate, ten parts of powdered sodium tribasic phosphate, and sixty-five parts of powdered anhydrous soap.
