• the liquid detergents in their cleaning properties could not reach the level of cleaning of a heavy-duty detergent (ie a solid mixture) until today. This is based on the limitation of a liquid detergent to liquid or water-soluble components.
• the key missing substance in a liquid detergent is the group of zeolites. These support the soil adsorption, as well as the gloss formation / color fastness during use.
• a current product trend is the way in which the detergent is portioned. This can be done firstly by the packaging of a liquid detergent in small polymer bags. Here all detergent substances are released at the time of dissolution of the polymer bag.
• Another physical modification of the detergent is to mix a detergent with a fatty alcohol so that desired shapes can be achieved.
• the release of the washing-active substances takes place via the dissolution of the structure of the detergent / fatty alcohol mixture.
• the laundry detergent disclosed therein is characterized by the combination of a carrier substrate with a liquid impregnation solution (two-phase product). Due to the preferred use of hydrophilic carrier substrates and impregnation solutions, there is a washout process which is comparable to the resolution of the polymer bags mentioned above in connection with the liquid detergents packaged in small polymer bags. Only the activation could be detected earlier.

• both liquid and powder detergents always contain at least one neutralized fatty acid which has a sodium carboxylate (from the exothermic reaction of sodium hydroxide solution with fatty acid) as a functional group.
• the liquid detergents always have a basic pH and powder detergents as soon as they are dissolved in water (ie in the wash cycle).
• the basic pH causes, inter alia, a greater swelling of the fibers.
• Further detergent components which are generally present in detergents are the cleansing surfactants and the enzymes, bleaching agents being additionally present in a powdered heavy-duty detergent and builder systems (zeolites) that can not be used in liquid detergents since
• a liquid fabric softener substantially contains ingredients to coat the fiber to provide a soft feel and ease of ironing, so surfactants are included in fabric softeners to alter fiber feel, such as esterquats, silicone quats, etc., while soil release surfactants , Water softeners, enzymes, bleach and neutralized fatty acids are not included (since it is not just about the dirt removal). For this reason, the pH of the fabric softener - in contrast to the liquid or powder detergent - located in the acidic range. Due to this incompatibility of the pH values of detergent and softener, the softener must always be separated, i.
• the dosage is therefore usually via a filling chamber for the detergent (pre- and / or main wash) and a separate filling chamber for the softener (after washing and between the rinses).
• the object of the present invention is thus to realize a fabric conditioner which does not have to be added in a separate washing cycle or fabric conditioning cycle. Another object is to provide a softener that can improve the fabric softening performance of a conventional softener. Summary of the invention

• the prior art is confronted with the inventive finding that the components of the fabric softener, which are incompatible with the actual detergent, are applied simultaneously to the detergent, in particular a liquid detergent, by application to a solid carrier material or cloth which can be added to laundry, in which case additionally the combination of the fabric softener components (A) with further solid washing-active substances (C), such as optical brighteners, zeolites, phyllosilicates, etc., in the dispersion applied to the carrier material or cloth (B) is applied - leads to a three-phase fabric softener, which just has the necessary for the cleaning performance of a heavy duty detergent substances, which lacks a liquid detergent.
