Definitions

  • the present invention relates to detergents or cleaning agents, in particular detergent or cleaning agent combination products, which in addition to one or more solid constituents also comprises liquids.
  • Detergents and cleaning agents and processes for their preparation are well known and are therefore widely described in the prior art. They are usually made available to the consumer in the form of spray-dried or granulated powder products or as liquid goods. Following the consumer's desire for simple dosing, in addition to these two classic variants, products in pre-portioned form have become established on the market and are also described comprehensively in the prior art, in particular pressed molded articles, i.e. tablets, blocks, briquettes and the like, as well as packaged in bags Portions of solid or liquid detergents and cleaning agents are described.
  • bags made of water-soluble film have again become established, making the tearing of the packaging by the consumer unnecessary.

  • Detergents and cleaning agents packed in bags made of water-soluble film are therefore described in large numbers in the prior art.
  • German patent application DE 11 30 547 discloses packages made of water-soluble polyvinyl alcohol films which are filled with non-liquid synthetic detergents. This document does not comment on the particle sizes of the packaged detergents.

  • Solid, in particular compressed washing or cleaning agents are often characterized by a delayed release of their ingredients as a result of the pressing. This disadvantageous property is contrasted by the high density and thus low dosage volume of this form of offer as well as its high active ingredient content.
  • Liquid detergents or cleaning agents dissolve comparatively quickly, but as a rule they cannot be assembled without the addition of solvents without washing or cleaning activity.
  • a goal of the development of modern detergents or cleaning agents is therefore the provision of supply forms which combine the advantages of solid detergents or cleaning agents with those of the liquid forms of supply.

  • Acid treatment in the context of the invention means that a sample of the clay (for example 1 g / l) in a 1 N HCl solution is exposed to a temperature of 80 ° C. for 15 hours. It must be mentioned that most clays can be destroyed by acid treatment with, for example, fluoride. In the context of the present invention, however, acid treatment means HCI treatment. Montmorillonites (magnesium saturated / air dried) usually have a maximum diffraction distance of 14-15 in the 001 plane when treated with X-rays. This maximum diffraction distance usually does not change by treating the clay with HCI.
  • acid-sensitive montmorillonites are preferred, for example montmorillonites, the crystalline structure of which is destroyed when they are treated with HCl.
  • montmorillonites the crystalline structure of which is destroyed when they are treated with HCl.
  • the use of such clay minerals has a soft touch-improving effect and ensures also for better dispersibility in the aqueous wash liquor or the aqueous textile treatment liquid.
  • the destruction of the crystalline structure can be determined by measuring the diffraction distance, so that the maximum diffraction distance to be expected in the 001 plane of 14-15 does not appear for the destroyed montmorillonites in the case of crystalline montmorilonites.
  • acid sensitivity is related to an increased exchange of aluminum for magnesium in the octahedral layer of the montmorillonite clay.
  • the above-mentioned acid-sensitive montmorillonites have the advantage that they enable a reduced tendency to gel and an improved dispersibility in the wash liquor. In addition, it has been observed that such clay minerals produce an improved soft feel.

Abstract

L'invention concerne des produits combinés comprenant au moins un corps moulé détergent ou nettoyant et au moins un corps creux rempli de liquide, qui est une pièce de moulage par injection et/ou de moulage par soufflage et/ou d'emboutissage profond et se compose au moins en partie d'un ou de plusieurs polymères solubles dans l'eau ou dispersibles dans l'eau. Lesdits produits combinés se caractérisent en ce que le(s) corps creux rempli(s) de liquide est(sont) lié(s) au corps moulé détergent ou nettoyant, en ce qu'ils permettent de préparer des produits combinés solide/liquide avec une complexité technique minimisée en matière d'emballage. Les produits combinés de ce type se caractérisent par une meilleure stabilité au moment de la production, du stockage et du transport.
