Definitions
- the present invention relates to a process for the preparation of granules containing organic peroxycarboxylic acid and the granules produced in this way. Moreover, the present invention relates to the use of these granules as a bleaching or bleaching component, in particular for their use in particular particulate detergents and cleaners, and for their preparation.
- particulate bleaching components such as alkali metal perborates or percarbonates
- alkali metal perborates or percarbonates are very sensitive to moisture, that is they lose, as well as solid detergents and makes ⁇ medium always have a certain water content or water from the air during their storage not is avoidable due to the loss of Aktiv ⁇ oxygen often within a short time their bleaching effect, if the bleaching component is not protected by enveloping against moisture.
- Peroxycarboxylic acids in particular imidoperoxycarboxylic acids whose most important representative is phthalimidoperoxycaproic acid (PAP), are likewise known as bleaching components for detergents and cleaners; Although these are less susceptible to hydrolysis, their storage stability is also insufficient to ensure long-term applicability of the corresponding washing or cleaning agent without accompanying loss of activity.
- PAP phthalimidoperoxycaproic acid
- a wax whose melting point is between 40 ° C and 50 0 C.
- the wax-coated particles are produced by spraying on the molten wax. In this case, the wax must first be heated to temperatures above its melting point, which may be disadvantageous with respect to thermally sensitive substances to be encapsulated.
- This method also has the disadvantage that the active substance is released only at temperatures above the melting point of the wax used - ie only above temperatures between 40 ° C and 50 0 C - which is not fair today's Self ⁇ or user requirements, since - against the background of the development of efficient washing and cleaning agent formulations and the saving of energy costs - often at lower temperatures, especially at about 30 ° C, to be washed. Furthermore, a wax with a high melting point has the disadvantage that it causes residues on the laundry, especially at low temperatures, since it is not completely emulsified at these temperatures.
- European patent application EP 0 653 485 A1 relates to active ingredient-containing capsule compositions which contain bleaching agents, such as, for example, bleaches.
- B. may contain PAP and in which the active ingredient is present in the capsule interior as a dispersion in oil.
- the preparation of these capsules, the shell of which is formed from hydrophilic polymers which become soluble only during the washing process or the application, requires a complicated emulsifying process, which is not easy to carry out technically.
- European Patent Application EP 0 816 481 A2 discloses a bleach granule which contains a peracid such as, for example, PAP and an agglomeration aid in a weight ratio of 1: 2 to 1:50, and citric acid monohydrate as the exotherm-controlling active ingredient.
- European Patent EP 0 695 343 B1 relates to amido peroxycarboxylic acid particles which have been coated by spraying a water-soluble salt in a fluidized bed and contain less than 2% by weight of water.

- Preferred imidoperoxycarboxylic acid is phthalimidoperoxycaproic acid. This is known, for example, from the European patents EP 0 349 940 and EP 0 325 328. It is commercially available in hydrous form as a so-called "wet cake", as is usually obtained in the context of their production from aqueous systems in relatively large crystals that can cake together. It can serve in this form or in any other particle form, for example as finely ground powder, from starting material for the process according to the invention. Amounts of imidoperoxycarboxylic acid of up to 80 wt .-%, in particular 50 wt .-% to 70 wt .-%, each based on the total particle, are preferred. Due to the production, minor amounts of the corresponding imidocarboxylic acid may also be present in the imidoperoxycarboxylic acid used which need not be removed in order to carry out the process according to the invention.
- the phlegmatizer which may be anhydrous or hydrate, is preferably selected from aluminum sulfate, alumina, boric acid, citric acid, the alkali borates, the alkali citrates and mixtures thereof. Mixtures of boric acid and citric acid and mixtures of citric acid and aluminum sulfate and / or aluminum oxide and optionally alkali citrate are particularly preferred. Sodium is the preferred alkali metal.
- the phlegmatizer is preferably used in powder or particle form of conventional grain size.
- the optionally used granulation aid is preferably selected from nonionic surfactants, anionic surfactants, polymeric glycols, polymers and copolymers of acrylic acid, methacrylic acid and / or maleic acid, which may also be in the form of their sodium, potassium or ammonium salts, and mixtures thereof.
