Definitions

  • the present invention relates to a detergent tablet with controlled release of the active component, comprising at least one active component with a detergent action and at least one hydrophobic substance, such as a fat or a wax for example.
  • the tablets currently manufactured in the detergent sector are very fast-dissolving and base the separation of immiscible components on the compression in layers
  • the rapid solubility of the tablet may constitute a serious problem since it does not allow a homogeneous distribution of the active component within the washing environment, with the consequent risk of damaging the fabrics owing to an excessive local concentration of the active component; moreover, the need to use a dual layer system in the case of active components which are immiscible with each other constitutes a disadvantage during production.
  • the object of the present invention is to provide a detergent tablet which allows not only a controlled release of the active component but also, where necessary, the mixing, in a single phase, of active components which are normally immiscible with each other.
  • the invention may be implemented more effectively using hydrophobic substances having a melting point of between 30 and 80° C, preferably between 55 and 75° C.
  • the tablet comprises 50 to 99% by weight of at least one active component with a detergent action and 1 to 50% by weight of at least one hydrophobic substance (the percentages are to be regarded as being relative to the weight of the tablet) .
  • the active component with a detergent action is present in an amount equal to 60-99% by weight, even more preferably in an amount equal to 65- 95% by weight; the hydrophobic substance is present in an amount equal to 1-30% by weight, even more preferably in amount equal to 1-15% by weight.
  • the method of preparing the tablets according to the invention is based on the following principles:
  • tablets having, mixed therein, active components which may interact if placed in close contact such as, for example, sodium percarbonate, sodium perborate and TAED (tetra acetyl ethylene diamine) ;
  • the active components which may be used with the present technology are:
  • detergents and softener phosphates, polyphosphates, EDTA, citric acid, sodium bicarbonate, sodium carbonate, alkyl sulphonates, trichloroisocyanuric acid, potassium dichloroisocyanurate, chloramine-T, phosphates, pyrophosphates, tripolyphosphates, potassium silicate, sodium silicate, xylene sulphonate, toluene sulphonate, cetrimide, sodium sulphonate, alkylaryl sulphonate, monoisopropanolamide, sodium metasilicate, sodium lauryl sulphate, non-ionic surfactants, anionic surfactants, cationic surfactants, protease, lipase, ⁇ -amylase, ⁇ - amylase, borax and sodium sulphate.
  • the hydrophobic retarding agents may be:
  • the tablet may contain filler excipients such as, for example, carbonates, phosphates, sulphates and the like, cellulose and cellulose derivatives, sugars, amides and proteins. These excipients are normally contained in amounts of between 0.1 and 20% by weight of the tablet, preferably between 0.5 and 15% by weight, even more preferably between 1.1 and 10% by weight .
  • filler excipients such as, for example, carbonates, phosphates, sulphates and the like, cellulose and cellulose derivatives, sugars, amides and proteins.
  • the term "essentially consisting of” is understood as meaning that the tablet, in addition to the active component and the hydrophobic substance, may contain minimum amounts (and in any case not more than 20% of the weight of the tablet) of the abovementioned filler excipients, such that active components, hydrophobic substances and any excipients form 100% of the tablet.
  • the following examples are given below in order to illustrate more fully the present invention without, however, limiting the scope thereof.
  • EXAMPLE 1 DISINFECTANT FOR LAUNDRY
  • Production method Mix the perfume with the melted paraffin and mix the TAED into the mixture, cool and granulate.
  • the granulate is mixed inside a screw mixer with the substances 4, 5, 6, 7, 8, 9 and the mixture thus obtained is compressed, forming tablets of 7.2 g.
  • EXAMPLE 2 DISINFECTANT TABLETS FOR DISHWASHERS
  • EXAMPLE 7 DISINFECTANT TABLETS FOR DISHWASHERS
  • EXAMPLE 8 MILD BLEACH FOR WASHING MACHINES
  • Production method mix the percarbonate with 2% of hydrogenated vegetable fat, compress and dry-granulate the tablets obtained.
  • Tablet decomposition test performed in a temperature- regulated dissolver.

Abstract

L'invention se rapporte à une tablette de détergent à libération progressive, qui contient de 50 à 99 % en poids d'au moins un composant actif à action détergente, et de 1 à 50 % en poids d'au moins une substance hydrophobe. La substance hydrophobe possède un point de fusion compris entre 30 et 80 °C, de préférence entre 55 et 75 °C. Ces tablettes peuvent se présenter sous forme d'un noyau enrobé, le noyau étant principalement constitué par le composant actif et l'enrobage étant principalement constitué par la substance hydrophobe ou, dans une forme de réalisation différente, ces tablettes peuvent se présenter sous forme de granulés compressés, constitués par un mélange du composant actif et de la substance hydrophobe.
