Process for producing contact lens cleaning tablets with a disinfecting action for one-step cleaning

A method for producing a contact lens one-step cleaning and disinfecting tablet designed to be dissolved in water comprising:

• (A) preparing a tablettable neutralizing core mixture consisting essentially of at least one biocompatible reducing agent, and/or at least one biocompatible catalyst, and at least one first buffering agent;
• (B) forming a core tablet from the mixture of step (A);
• (C) preparing a jacket mixture consisting essentially of a biocompatible cleaning and disinfecting agent which is a hydrogen peroxide generating compound and at least one alkylglucoside of the general formula R.sub.1 O(C.sub.n H.sub.2n O).sub.y (Z).sub.x wherein
• R.sub.1 is a C.sub.8-18 alkyl,
• n is 2 or 3,
• y is 0-10,
• Z is glucose, and
• x is 1-10,
• and a second buffering agent;
• and
• (D) enveloping the core tablet of step (B) with the jacket mixture of step (C) so that it is completely surrounded by a stable outer layer thereof.
