Definitions

  • This invention relates to the stabilization and regulation of per-salts and otherper-compounds constituting one component of treating agents of a diverse nature such as used in bleaching,
  • the invention relates to a new class of stabilizing and regulating agents for bleaching compositions or washing, cleaning, soaking, rinsing, penetrating, scouring and the like compositions containing bleaching constituents and their resulting compositions of matter.
  • thetreated materials such, for example, as textiles, clothing, and the like, and exercises a bleaching and disinfecting function at one and the same time. Furthermore this exceedingly fine dispersion of gaseous oxygen loosens soil particles adhering to the surfaces of the goods, thereby making their emulsification and removal by the other cleaning constituents much easier.
  • per-compound bleaching agents alone or in combination with detergents and cleaning agents, it is essential that these compositions be absolutely stable during storage or transportation even if the period of storage or transportation be an extended one, The demands of the trades are not satisfied simply by the provision of a stable composition, but it is necessary that the per-compounds, when put in solution for use, deliver the oxygen uniformly throughout the whole period of the washing and bleaching operation. If regulating agents controlling the speed and uniformity of the delivery of oxygen from compositions using per-compounds are not present, all of the oxygen is delivered almost instantaneously or very quickly upon placing the compositions in solution.
  • This instantaneous delivery of oxygen has great disadvantages, as more oxygen is given ofi per unit bleaching ,or cleaning, since the cleaning fluid does not have sufllcient time to perform its emulsifying function and more oxygen is present than can be used effectively to contact the material either to bleach it or loosen the dirt from 55 other hand, it is easily possible to use compounds which retard the evolution of ornrgen from the I per-compounds to such aldegree that not enough.
  • oxygen is delivered per unit of time to attain maximum efliciency during the washing, cleaning, bleaching, or like operations, or the com- I pounds may retard the evolution of oxygen to such an extent that oxygen remains in the percompounds after the cleaning or bleaching operations have been completed.
  • the great problem is to find a stabilizing and regulating agent for compositions containing per-compounds that may, by a variation in its proportion, efiectively stabilize the per-compound during storage and' transportation and at the same time regulate the speed and the uniformity of the delivery of the oxygen when placed in solution to that which will assure maximum utilization of the oxygen present and produce cleaning and bleaching effects desired.
  • Another'object of the instant invention is to provide compositions containing per-compounds which are stable in storage and during transportation.
  • Yet another object of the invention is to control the speed and uniformity of the liberation of oxygen from compositions containing per compounds.
  • a further object of the invention is to produce a class of bleaching agents containing per-compounds which are stable in storage and during, transportation and which uniformly deliver oxygen when placed in solution.
  • Still another object of the invention is to produce a new class of compositions for cleaning, washing, rinsing, bleaching, and like operations which are stable in storage and during tra'n's-. portation and which control the liberation of oxygen even in hard waters.
  • the present invention relates to stabilization agents composed of combinations of magnesium silicate with any one or more of a number of water-soluble salts of organic amino acids having at least two carboxyl groups in the alpha positions for every basic nitrogen atom present, which agents render compositions containing per-compounds stable during storage and transportation and also produce a uniform and complete oxygen liberation from such compositions during rinsing, bleaching, cleaning or other operations.
  • compositions containing per-compounds makes it possible to procure complete utilization of the oxygen present and to obtain uniform delivery of the oxygen, thereby assuring a uniform bleaching, disinfecting, cleaning, or the like action.
  • the magnesium silicate used must be preformed or exist as such in the composition before use, for the desired effect is not obtainable with mixtures of the organic amino acids and. compounds .capable of producing magnesium silicate in the treating solution. It may be procured, in known manner through the reaction of magnesium sulfates with water glass.
  • water-soluble salts of various organic amino acids may be used, such, for instance, as the sodium and potassium salts of imino-diacetic acid, imino-disuccinic acid, nitrilotriacetic acid and the like.
  • Numerous other amino acid salts of the type disclosed are procuredby substituting alkyl, aryl, aralkyl, oxyalkyl and likeradicals or their substitution products for the; hydrogen atoms of the imino acids.
  • Other suitable compounds can be procured by substituting the alkyl, aryl, aralkyl, oxyalkyl and the :like'radicals or. their substitution products for the-.hydrogen atoms of the methylene radical of the, amino" acids 'esulting in compounds such as the salts of C dimethyl-nitrilotriacetic acid.
  • the amount of magnesium silicate needed for the purpose-of this inve'ntion is very small, frequently ranging from .0.5-'-l .5% by weight of the total composition.- -The organic amino acid salts, however, must be present in; excess of the magnesium silicate.
  • the preferred ratio requires five or more times as much amino acid salt as magnesium silicate but the ratio may vary from 2-20 or 3.5-20 or more times as much of the amino-acid salt as of the silicate.
  • the aforementioned stabilizing and' regulating agents may be used with a wide variety of per-compounds and compositions containing percompounds. Excellent disinfecting, rinsing, bleaching, and the like agents are procured when the stabilizing agents are used with oxygen producing per-compounds alone, such as with sodium perborate and other perborates, percarbonates, perphosphates, perpyrophosphates, h y d r o g e n peroxide, and like peroxides and similar compounds.
  • washing and cleaning compositions are obtained in accordance with the present invention by adding detergents such assoaps, sodium and other water-soluble salts of sulfuric acid esters of higher molecular fatty alcohols; or salts of sulfonated fatty alkyl compounds-g er mixtures thereof, salts of methyl ta'urinesacylates by means of higher fatty acid fradicals or other saponaceous compounds.
  • detergents such assoaps, sodium and other water-soluble salts of sulfuric acid esters of higher molecular fatty alcohols; or salts of sulfonated fatty alkyl compounds-g er mixtures thereof, salts of methyl ta'urinesacylates by means of higher fatty acid fradicals or other saponaceous compounds.
  • compositions of the instant inven-' tion havethe unexpected quality of delivering oxygen uniformly and completely even in hard wateri' Nevertheless, alkaline agents such as were ;'Jglajss, sodium metasilicate, borax, soda, phosphates, such as alkali orthoor pyro phospha't'es' and like alkalinity-imparting compounds may 'used wherever they serve to aid in the washing, cleaning, bleaching or rinsing operations without in any way affecting the utility of th zstabilizing and regulating agents, and the resulting compositions are considered a specific embodiment of the instant invention.
  • detergent compositions of the instant invention are marketed in the form of powders, lumps, flakes, strips, chips, granules, solutions or pastes.
  • One particular advantage of the detergent compositions of the instant invention is that the per-compounds do not decompose when in the solid or powder form.
  • the new products of the instant invention find use in many branches of industry as well as-in the household. They are especially valuable as detergent, bleaching, cleaning, and washing agents in the treatment of textiles, clothing, and the like, although they find use wherever bleaching, washing, cleaning, soaking,
  • Example 1 Ten parts of sodium perborate are thoroughly mixed in a suitable mixing apparatus with 32 parts of soap, 12 parts of soda, 14 parts of the sodium salt of nitrilotriacetic acid and 1 part of magnesium silicate. An excellent detergent is obtained which is useful in many branches of industry and in the household for washing tex tiles, clothes and the like.
  • Example 2 Twelve parts of sodium perborate, 8 parts of soda, 20 parts of sodium salt of imino-diacetic acid and 1 part of magnesium silicate are mixed with each other in an edging mill. A bleaching agent is obtained which is excellently suitable for bleaching a wide variety of textiles in the textile industry.
  • Example 3 Ten parts of sodium perborate, 30 parts of the commercial mixture of the sodium salt of sulfonated higher .fatty alcohols, 10 parts'of soda, '7 parts of sodium pyrophosphate, '7. parts of the sodium salt of nitrilo-triacetic acid and 2 parts of magnesium silicate are well mixed with each other.
  • the product is an especially valuable detergent, solutionsof which deliver oxygen slowly and uniformly.
