Definitions

  • the present invention relates to a process for the preparation of particulate detergents or cleaners.
  • Particulate detergents and cleaners usually consist of a variety of ingredients, which are usually incorporated into a plurality of particulate components in the entire agent because of mutual incompatibilities.
  • examples of such mutually incompatible ingredients are bleach and bleach activator, which are to react with each other under conditions of use in aqueous solution and then give a desired increased bleaching performance, but not allowed to react with each other during storage, since they are no longer available for the desired application stand.
  • a less striking example of the non-optimal interaction of individual ingredients of detergents and cleaners results from their pH-dependent performance.
  • anionic surfactants and builders for example, require an alkaline pH to fully develop their performance.
  • both dirt particles as well as most textile fibers form an increasing number of negative charges with increasing pH, which leads to increasing repulsion among them and is therefore beneficial to the desired washing result.
  • textile washing has been carried out with more or less alkaline wash liquors since ancient times. The same applies analogously to aqueous solutions for cleaning hard surfaces, for example in the context of machine cleaning methods for dishes.
  • Detergent ingredient is understood to mean a substance whose addition to water, which has a pH of 7, leads to an acidic or alkaline pH.
  • mp is the total mass of the particles to be treated and r is their mean particle radius.
  • a particle to be treated according to the invention may optionally contain all ingredients of a detergent or cleaning agent, ie it is possible with the method according to the invention to coat a finished washing or cleaning agent.
  • a detergent or cleaning agent ie it is possible with the method according to the invention to coat a finished washing or cleaning agent.
  • Such alkaline ingredients are preferably alkali silicates, alkali aluminosilicates, alkali phosphates, alkali carbonates, alkali metal perborates and alkali percarbonates, and mixtures thereof, with sodium being the preferred alkali metal.
  • liquid or pasty acidic component preference is given to applying the liquid or pasty acidic component, optionally in molten form, in a mixer or granulator to the optionally heated particles consisting at least proportionally of an alkaline detergent or cleaning agent ingredient.
  • Particularly good coatings are achieved by applying the acidic component to the particle over a period of 5 minutes to 20 minutes.
  • the inventive method is, presumably - without this theory To be bound by the neutralization reaction of the acidic coating material with the alkaline particle on its surface and to a certain extent under its surface, a particularly dense and comparatively little or slowly water-soluble coating marafffen having a reliable tightness after entry into an aqueous system and thus enables the production of detergents and cleaners with a step-shaped pH profile.
  • the particles obtainable according to the invention contain in their core almost exclusively the constituents of the particle originally used. This core is surrounded by a layer in which increasingly higher concentrations of acidic coating material or its salt formed with the alkaline component occur from the inside to the outside, wherein the outer surface can be formed entirely of acidic coating material.
  • Components of the particle of alkaline material, in addition to the alkali component may be all customary with this compatible ingredients of detergents and cleaners, as long as they are solid or ready to confection.
  • these include, in particular, other builders, surface-active surfactants, other peroxygen compounds, peroxygen activators, sequestering agents, electrolytes and other auxiliaries, such as dye transfer inhibitors, silver corrosion inhibitors, foam regulators and dyes and perfumes, wherein the presence of peroxygen activators in the particle of alkaline material less preferred is when this particle also contains peroxygen compound.
  • the particles produced by the process according to the invention are, preferably after mixing with at least one further particulate component, as Detergents or cleaning agents used, which may be agents for manual or machine washing or cleaning in particular.
  • the at least one further component contains at least one active ingredient whose washing or cleaning action at a lower pH than that resulting from the dissolution of the alkali component contained in the particles produced by the method according to the invention is higher than at the pH at dissolution of said particle.
  • this active ingredient is selected from enzymes or Enzytrmnischenoder, wherein in the case of the mixtures, the individual active ingredients may also be contained in a plurality of different composite particulate components.
  • the at least one further component of such a solubility that it releases as much of the active substance contained in it under the initially lower pH conditions, but essentially only after pH increase by the then higher alkalinity of him surrounding aqueous Systms unfolds its full effect, or otherwise reacts with the then liberated alkali component.
  • An example of the last-mentioned variant is a bleach activator which is soluble or formulated in a lower pH and which reacts with a bleaching agent released from the coated particle according to the invention and which, by being already dissolved, can rapidly develop a strong bleaching action.
  • 1 kg spheronized sodium percarbonate having an average particle diameter of 400 microns were premixed with 25 g of stearic acid (dandruff) in a cold state. This premix was placed in a commercial ploughshare mixer with stud shovel preheated to 90 ° C (jacket temperature). At speed level 2 and a measured product temperature of 80 ° C was compounded reactive for 20 min. The hot product was removed and can be used after cooling in the usual way, for example for the production of detergents or cleaners.
  • Each 100 g of spheronized sodium percarbonate having an average particle diameter of 1400 microns were added in a beaker with 2.5 g or 1.5 g of stearic acid and heated to a product temperature of about 80 ° C with stirring. After the molten stearic acid had been absorbed into the alkaline particles, the mixture was further reactive compounded at about 80 ° C. for a further 20 minutes.
  • Fig. 1 the pH curve is reproduced after incorporation into water of the product prepared by application of 1.5 g of stearic acid.
  • Fig. 1 also contains the pH curve of the uncoated percarbonate.
