Definitions
- the present invention relates to an improved method of laundering and to a shelf stable laundering composition therefor.
- the type of detergent presently employed in laundering consists almost universally of the so-called synthetic detergent type wherein the main surface active agent is an alkyl aryl sulfonate.
- the synthetic type of laundering powder or liquid contains additional water softeners and so-called builders, carboxy methyl cellulose, all of which aid in controlling the foaming qualities of the product, in controlling the removal of soil from the goods to be laundered, and in preventing redeposition of the soil uniformly on the goods once the soil is removed therefrom.
- the usual synthetic detergent is compounded with soluble perborate, preferably sodium perborate, in any suitable amount.
- the amount of sodium perborate compounded with the detergent will be from about 5 to about 30% by weight.
- a catalyst is introduced for speeding up this particular reaction.
- the catalyst is present in extremely small amounts in the final laundering solution and may be present and effective in quantities so little as 0.25 to 5 parts per million of solution.
- the sodium perborate under the influence of the catalyst, decomposes and provides eifective bleaching action for the purpose of whitening white goods, brightening colored goods, and removing the usual stains encountered in laundering operations such as vegetable juice, ink,
- the catalyst preferred for accelerating the decomposition of the sodium perborate and liberating the active oxygen therefrom is a copper-containing soluble salt and is useful by reason of the fact that it may be used in such small quantities and any deposition of copper upon the goods is so slight as not to be subsequently noticeable.
- a typical formulation of a detergent composition of the present invention would include:
- Alkyl aryl sulfonate 140 Sodium tripolyphosphate 140 Tetrasodium pyrophosphate 60 Carboxymethyl cellulose (CMC) 4 Sodium metasilicate 22.8 Sodium perborate tetrahydrate 64 Copper sulfate pentahydrate 2.84
- the copper content should be from about A part per million to not more than 10 parts per million, with a preferred concentration of from 2 to 4 parts per million, a concentration best adapted for use in domestic laundering procedures.
- any soluble copper salt will serve, as for instance highly soluble salts such as the nitrate or acetate or slightly soluble salts such as the phosphate, among others.
- the dissolved copper compound is the catalyst and the salt chosen should provide a copper concentration in the laundering solution of from about 0.5 to parts per million.
- a compound detergent and oxidant of 4 oz. of such composition in 15 gallons of water will produce a concentration of copper of approximately 3 parts per million of the laundering solution, while the soluble copper salt should be present in dry mix in an amount sufficient to produce from 0.04% to 0.4% copper.
- a stable dry-mixed detergent composition comprising, an alkyl aryl sulfonate synthetic detergent, a water-soluble perborate, and a water-soluble inorganic copper salt, wherein all the components of said composition are admixed and in intimate contact with each other, the perborate being present in an amount sufficient to produce an active oxygen content in the range of 0.8% to 2.4% by weight, and the inorganic copper salt being present in an amount sufficient to produce a copper content within the range of 0.04% to 0.4% by weight and being substantially free of surface coatings.
- a method of laundering which comprises heating the goods to be laundered in an aqueous bath at a temperature between about F. to F. until the laundering is completed, said aqueous bath containing an alkyl aryl sulfonate synthetic detergent, a watersoluble perborate, and a water-soluble inorganic copper salt, the amount of perborate being sufficient to produce an active oxygen content in the composition of from 0.8% to 2.4% by weight, the amount of copper salt being sufiicient to produce a copper concentration in the range of 0.5 part per million to 10 parts per million by weight of the laundering solution, and wherein said synthetic detergent, said water-soluble perborate, and said water-soluble inorganic copper salt are introduced into said aqueous bath in the form of a dry-mixed composition wherein all the components of said composition are admixed and in intimate contact with each other, and said inorganic copper salt being substantially free of surface coatings.
