I-lypochlorites, especially lithium hypochlorite, is preferred.
6 Claims, No Drawings BACKGROUND OF THE INVENTION The accumulation of hair on hair brushes and the like used for conditioning hair, and the difficulty of thereafter cleaning the brushes is a quite common experience in life. The hair and dust and dirt carried along with it when brushing become entangled in the bristles of the brushes as well as finding their way to the internal portions thereof. When one tries to clean the brushes it requires a considerable effort to attempt to individually remove strands of hair and occluded material from their entangled stage within the bristles and brush structure; an effort which is both time consuming and invariably considerably short of complete success in cleaning and removal of hair. Mere conventional soaking in soapy water, ammonia or the like does not overcome this problem and indeed, may make it more difficult to remove hairs.
The problem is aggravated in the case of professional beautician and barber shops and the like, when due to means for cleaning hair brushes of matted hair and the like in a manner which is capable of being used by the average housewife in her home as well as being of utility to the professional beautician and barbering trades. More particularly, means are taught whereby hair brushes, particularly those having synthetic bristles such as nylon bristles on a plastic base, e.g., typically acrylic, polystyrene, polypropylene and polystyrene/acrylonitrile are cleaned by immersing the brushes in a solution having the properties indicated below.
SUMMARY OF THE INVENTION More particularly, in accordance with the present invention, hair brushes, particularly those having synthetic (non-protein) bristles such as nylon, are cleaned of occluded hair by soaking said brushes in a solution containing an oxidizing agent capable of dissolving the hair strands. The solution of oxidizing agent must be capable of dissolving the hair in periods of less than 24, preferably less than 12 hours (overnight) and must not be so toxic or strong as to constitute a danger within the home. The solution must permit the homemaker to be able'to place her hands briefly in it to put the brushes in solution as well as to remove them after the brush treating step. It should be noted, however, that the user should avoid excessive contact with the skin and follow any such contact by flushing the skin with water. Additionally, the oxidizing compound used in making the solution must be available in sufficiently concentrated form so as to not require extremely largeamounts in order to dissolve the hair particles. In other words, the oxidizing agent in amounts of no more than 50 grams of pure compound per liter of tap water should be capable of dissolving the hair without attacking the synthetic bristles.
More particularly, it has been found that oxidizing agents containing available chlorine are especially suitable for the practice of the present invention. For typical home use such chlorine supplying oxidizing agents, when added in relatively minor amounts to tap water, should be capable of providing available chlorine in solution in an amount of about 0.1 to 20, preferably 0.5 to 10, especially 0.5 to 5 grams per liter of solution. The hypochlorites are particularly suitable in this regard since they are capable of providing substantial amounts of available chlorine per gram of compound added to water. The alkali hypochlorites, e. g., a lithium hypochlorite, potassium hypochlorite and sodium hypochlorites are especially useful, although alkaline earth hypochlorites such as calcium and magnesium can be used although they tend to give some precipitation in hard water. Lithium hypochlorite is particularly preferred due to its ready solubility, good stability characteristics as a powder and high available chlorine content.
Although not necessary, in some cases it may be desirable to add a second agent to the oxidizing agent containing available chlorine to modify its characteristics in one way or another. Though not necessary for lithium hypochlorite, by way of example, when employing sodium hypochlorite various materials such as alkalies, alkali silicates, alkali polyphosphates, potassium carbonates, etc., may beadded in suitable amounts, e.g., of about 10 to 50 wt. percent of the hypochlorite in order to further stabilize same.
Similarly, it may be desirable to add a second material as a means of reducing the amount of chlorine supplying oxidizing agent required by providing a pH value in solution which will tend to liberate chlorine faster and therefore reduce the necessary time period for treatment. Typical of such materials might be the addition of sodium bisulfate to lithium hypochlorite in amounts of 15 to 40 wt. percent thereof as a means of giving a pH of 7 to 8.5 to the solution which enhances the liberation of available chlorine from solution and reduces either the time period for treatment with a given amount of hypochlorite, or reducing the amount of hypochlorite for a given time period treatment.
In addition to the hypochlorites, other chlorinated oxidizing agents such as chlorinated isocyanurates, chlorinated trisodium phosphate and the like can be used as a source of available chlorine.
While oxidizing agents giving off available chlorine are particularly preferred in terms of requiring a reduced amount of material and/or shorter time periods for treatment, other oxidizing agents such as potassium monopersulfate, potassium persulfate and sodium percarbonate can be used but at relatively high concentrations and lower effective rates as compared to hypochlorites.
As used in the present specification, the term available chlorine serves as a measure of the oxidizing potential of a chlorine-containing compound, and generally reflects the proportion of chlorine in its molecule. it is determined by titration with thiosulfate or arsenious acid, as described in Technical Methods of Analysis, pg 44, Griffen, Second Edition (McGraw-Hill, New York).

In its most preferred form the packets would comprise an aluminum foil package having a polyethylene inner liner having contained therein measured quantities of the oxidizing agent in a powder or solid form. The solid, of course, could comprise a pill or molded solid which dissolves readily in water.
By way of specific example, the package could contain five to thirty grams of lithium hypochlorite, which when added to a typical volume of water sufficient to cover the hair brushes to be treated in a bathroom sink would give a 0.5 to 1.5 weight percent solution of lithium hypochlorite. These pre-packaged containers containing oxidizing agents in relatively small amounts are a unique article of commerce and would take the form of the type of package used for hand washing towellettes or the like M V I WW It should be notedthat the present invention is concerned with the cleaning of hair and associated foreign matter which has been matted and/or dispersed in hair brushes although it can, of course, be similarly used to dissolve hair from combs and the like. It is thus clearly distinguished from the use of oxidizing agents as a means of bleaching or sanitizing various articles such as milk tanks, processing of textiles, etc. Similarly, it is distinguished from the use of oxidizing agents for removal of food or tobacco stains as well as food particles since obviously this is not the type of problem faced when cleaning hair from hair brushes. The latter presents some unique problems due to the intertwining of the strands of hair and bristles as well as imbedding within an entangled mass.
Various modifications can be made to the present invention. For example, the solution can be made from a liquid source of oxidizing agent, such as a bottled concentrate. However, a powder or tablet form is preferred.
