  • Such a form of delivery also guarantees easiest handling and application for the consumer.
  • EP 339 702 relates to encapsulated, non-aqueous, liquid detergent compositions, in which a structure-forming connection, a so-called "structurant", the deposition of organic Solvent-dispersed solid particles prevented.
  • the "structurant” is according to Reference to EP 466 199 an acid. The optimal pH for washing processes from 7 to 9 can thus cannot be set satisfactorily.
  • the detergent composition further contains proteolytic Enzymes. The presence of solids continues to make up corresponding amounts Solvents or dispersants necessary, so that the content of detergent substances in the Detergent composition can be very low.
  • DE 43 01 358 is directed to a gelatin capsule, which is a pasty body and / or textile detergent includes.

  • the branching of the alcohol also reduces the mobility of the entire surfactant.
  • Fatty alcohol (C 12 -C 14 ) polyethylene glycol (2 EO) ether sulfate mono-, di- or triisopropanolammonium salts are ideal for encapsulation due to their rheological properties.
  • the flow curve corresponds to that of a Newtonian liquid, ie the viscosity is independent of the shear rate. This is advantageous for every encapsulation process, but especially for the rotary die process. Due to the high molar mass, which is 438 g / mol for the monoisopropanolammonium salt and 558g / mol for the trisopropanolammonium salt, these surfactants are inert to the capsule material.
