Description

Soap wash for scouring pads

The invention relates to soap mixes for scrubbing balls and the like and to a method for their production. The well-known soap mixes of this type contain considerable amounts of Kalumselfe as an important and necessary ingredient. Potassium soaps are essential, however more expensive than the corresponding sodium soaps. With the present invention, soap mixes for scouring balls and the like are now to be proposed, which one contain potassium compound other than soap and all soap as sodium soap. It has been found that the addition of a potassium compound reduces the flowability of the soap mass in the molten state when applied to the Regulates scrubbing ball threads and the like.

The soap mixes according to the invention for the impregnation of hay bales can be made from the following components in exist in the following quantity ranges:

In the following, the invention will be described primarily in relation to impregnation of steel wool balls described, but of course also balls made of all other metal threads or Plastic shutters are impregnated with the soapy water.

If larger amounts of 6% by weight are used, it has been found that the foam improvers make processing of the soap mass more difficult and impair its appearance. With the shorter chain fatty alcohols, eg those with 6 to 10 carbon atoms, good results are achieved with regard to the properties of the skin, but they are less suitable for various purposes because of their possibly unpleasant odor. When using petroleum alcohols with a longer chain, eg with 12 to 18 carbon atoms, it has proven to be expedient to use combinations of these fatty alcohols in order to achieve the optimum foam effect. Fatty alcohols suitable for the purposes according to the invention are, for example, ootanol, deoanol, tetradecanol, hexadecanol, octadecanol, dodecanol and the like, of which dodecanol is preferred. When using saturated fatty alcohols containing 15 to 18 carbon atoms, particularly good results were achieved with mixtures of C ₁₂ , C, 4- and C, g-alcohols. It has also been found that the foam improvers extend the useful life of the scouring pads compared to the same balls without the addition of foam improvers.

The soap mixes according to the invention can, as prepared It has been said "can be applied to the scouring pads in any conventional manner, but the mixed soap of the present invention is particularly useful for Spray on. On the other hand, the well-known soap mixes are due to their physical properties to spray on scouring pads unsuitable. Thus, in attempts to spray the known soap mixtures onto scouring balls, products of poor appearance with uneven distribution of the soap mass were generally obtained, and in addition, large soap losses occurred during spraying.

Particularly satisfactory products are made with the soap preparations according to the invention or other sprayable soaps or synthetic detergents

a procedure obtained »in which you get a flat Strips of scouring pad wool or fibers of a thickness suitable for the shape of the finished scouring pad and width sprayed on at least one side with a detergent. The detergent is made from one Reservoir sprayed on by means of a pump duroh a spray nozzle. On the strips are then in certain Semi-solid, plastic, paste-like lumps of soap or detergent measured at intervals or cores applied, which remain at the application site and retain their shape. The one used for this Detergent can be the same as that used to spray or a different detergent compatible therewith. The delivery sequence of the semi-solid core mass and the feed speed of the strip are thus one on top of the other coordinated that separate bodies are formed from the core mass on the strip. The strip will then cut at regular intervals so that each section is a single delimited soap body having. The strip can in another embodiment of the process also torn into pieces of the desired length or prior to the application of the soap mass get cut. The individual sections of the stiff are rolled into a cylinder so that the wasoh-

central core is located in the center of the cylinder, and then pressed into the finished scouring balls. "Cutting" here means cutting or tearing the strip understood from steel wool or other scouring pad material to pieces of the desired length.

In a preferred embodiment of the invention, steel wool is used as the scourpad fiber. It has been found that the type of steel wool can be varied within a wide range depending on the desired texture and structure of the finished scouring pads. Commercially available steel wool of the quality ^{classes from about n} l ^w to ¹¹ OO "are preferably used. Long-fiber steel wool is preferably used * which gives the finished scouring pads the desired elasticity and resilience and at the same time has fewer short ends which can make the consumer's hands rough .

For spraying the scouring pad wool or »fibers any spray system suitable for soap masses can be used.

When using steel wool strips, ssum is sprayed preferably a soap mixture used.

For most soap masses, spray nozzles with opening widths of 0.0125 to 0.06-5 cm are suitable. The soap mixture to be sprayed is kept at a temperature above which the soap is liquid and can be sprayed and below which the sprayed soap dries too quickly to adhere satisfactorily to the steel wool. At very high temperatures, the similar water from the soap is rapidly vaporized so that the soap partially dries and is not liable enough. Satisfactory results are generally achieved at temperatures of the soap mixes of about 43 to 99.degree. Preferably, the soap mixtures are used having a temperature of about 65 to 88 ⁰ C. The soap mixture is sprayed onto the steel wool tape in an amount of 3 to 7 g of soap solids per 6 g of steel wool. The soap can either be sprayed onto one or both sides of the flat steel wool strip, but preferably only one side of the strip is sprayed. '

The detergent used as the core mass can consist of any detergent that is compatible with the sprayed detergent and as a semi-solid, plastic, paste-like mass can be sprayed on and after
