Definitions

  • the invention relates to a detergent or cleaning agent from at least two of a different shape having particle types.
  • Detergents are often not differentiable for the consumer. As far as they are particulate agents, they usually consist of white or more or less bright particles, which at least seem to leave behind the impression that it is a uniform-uniform product. In order to give the user, who may or may not have been sufficiently careful with the instructions for using the product, hints about which type of detergent is involved, some manufacturers have recently begun to stain portions of the particulate agent, such as one otherwise white universal detergent to add a blue or green colored particle fraction, a so-called color detergent composed of a plurality of different colored particles, or a detergent, which is to indicate particularly laundry-care properties to attach particles in muted reds or yellows. The same applies to hard surface cleaners.
  • the present invention is also based on the object of enabling an optical-aesthetic differentiation of particulate detergents or cleaning agents.
  • detergents should also include aftertreatment agents for the laundry, for example fabric softeners, as well as universal or heavy-duty detergents, mild detergents, color detergents, wool detergents, curtain detergents, modular detergents, stain salts, laundry starches and stiffeners and optionally ironing aids.
  • the invention is therefore a particulate or washing or cleaning agent comprising particulate prefabricated detergent ingredients, containing a first type of particles having a form factor of at least 0.80, and a second type of particles having a form factor of less than 0.80, preferably at least 0 , 02 is below the shape factor of the first species particle.
  • the washing or cleaning agent according to the invention thus has at least two types of particulate constituents.
  • the term "type" in the sense of this invention means that the particles do not necessarily have to differ in their composition, but that they have a different shape from each other:
  • the first kind to the unbiased viewer substantially round, that is largely spherical, and the
  • the second type differs identifiable from the spherical shape, for example, this second type may be ellipsoidal, hemispherical, or - and this is particularly preferred - be shaped quite irregularly, for example as a so-called "fracture”.
  • particles of the first and second types differ, apart from their shape, also by their ingredients.
  • the first type of particles may well comprise several different and / or composed of different ingredients particles, for example builder particles, surfactant compound particles, bleach particles, bleach activator particles, foam regulator particles or granular formulated enzymes, which are optionally different in size but are all substantially round or spherical , It is essential to the invention that at least one further particle type which is not round is present next to it.
  • the property "not round”, that is, a deviation of the shape of the particles of the ideal sphericity designated here as the second type, can be made tangible and quantified with the aid of the shape factor explained in more detail below.

  • the particulate particles of the first type present in the washing or cleaning agent are present in a narrow particle size distribution, ie the ratio of d50 to d90 is as high as possible.
  • the ratio of d50 to d90 is at least 0.78, preferably at least 0.8, more preferably at least 0.83, and most preferably at least 0.85.
