Definitions

  • the present invention is in the field of detergent preparations and relates to active ingredient capsules with stably incorporated dyes.
  • Core-shell capsules containing microcrystalline cellulose in the core are well known from the prior art, namely, for example
  • WO 2017 107628 A1 also discloses chitosan capsules which contain microcrystalline cellulose in the capsule shell.
  • the object of the present invention was therefore to provide capsules loaded with active ingredients and dyes, in which the active ingredients and dyes are stably incorporated, so that no bleeding takes place.
  • the capsules should be resistant to breakage, so that a sufficiently large or prolonged mechanical force is required before they break open and release both the dye and the active ingredient.
  • the capsules should be surfactant-stable, i.e. the shell should not disintegrate even in an environment containing a high level of surfactants, such as a soap base or a cream.
  • a first object of the invention relates to active ingredient capsules that can be obtained or obtained by
  • Another subject of the invention relates to an analogous production process, comprising or consisting of the following steps:
  • microcrystalline fibers specifically microcrystalline cellulose
  • the fiber is sealed with the dye in the second step.
  • the capsules are produced by coacervation in a hardening or precipitation bath and are not only extremely break-resistant, but also surfactant-stable.
  • the active substance capsules according to the invention can be obtained as described above by providing an emulsion comprising fibers, active substances, dyes and gel formers and dripping the emulsion into a hardening or precipitation bath.
  • the capsules are intensely colored after production. However, since they are only added to the end products in small amounts, they only affect their color when they are mechanically broken up and then primarily color the foam.
  • microcrystalline is understood to mean fibers or fiber fragments that have dimensions of about 100 to about 1,500 ⁇ m, preferably from about 200 to about 1,200 ⁇ m and in particular in their longest extent (“length”) from about 500 to about 1000 ⁇ m.
  • these fibers are spherical in shape.
  • MCC microcrystalline cellulose
  • MKZ microcrystalline cellulose
  • E460i microcrystalline cellulose
  • Microcrystalline cellulose is used in particular in direct tabletting. MCC is made from woody parts of plants, not from waste paper. Here, the vegetable cellulose is freed from non-crystalline cellulose parts with diluted hydrochloric acid at temperatures above 100 °C. Thereafter, optional carboxylation can occur to increase hydrophilicity. Thus, a microcrystalline carboxy- or carboxymethyl cellulose is also included in the present invention.
  • component (b) the selection of the active ingredients that form component (b) is not critical since it depends only on the intended use. However, perfumes and/or antimicrobial agents are particularly preferred.

  • chitosans In contrast to most hydrocolloids, which are negatively charged at biological pH values, chitosans are cationic biopolymers under these conditions. The positively charged chitosans are able to interact with oppositely charged surfaces and are therefore used in cosmetic hair and body care products and pharmaceutical preparations. emulsifiers
