Definitions

• WO 2010/076803 A2 describes a topical multicomponent system in which at least one component comprises an active substance which is coated with a metal oxide. Detergents or cleaning agents are not described.
• a solution or dispersion of the starting materials is preferably first prepared, and this mixture is advantageously stirred for a period of at least 1 minute at room temperature (21 ° C).
• thermal energy may also be supplied, e.g. by heating to 60 ° C.
• the particle size of the metal oxides used is basically freely selectable. However, it is preferred that the metal oxides particle sizes ⁇ 1000 ⁇ , advantageously ⁇ 500 ⁇ , in a further advantageous manner ⁇ 100 ⁇ , preferably ⁇ 1 ⁇ , in particular ⁇ 0.1 ⁇ . A possible lower limit of the particle size may e.g. at 1 nm or 10 nm.

• a significant advantage is that the invention allows a fragrant effect by Wederbefeuchten.
• objects treated with the washing or cleaning agent according to the invention e.g. Textiles, after which they surprisingly exude a particularly intense fragrance when they are moistened again.
• This effect is beneficial for many processes of daily life.
• a towel washed with the detergent of the invention unfolds on drying e.g. of crockery or the human body, by the absorbed moisture a fragrance effect.
• appropriate underwear e.g. Undershirt, by the body moisture a renewed fragrance effect are triggered.
• This effect ie a re-flow of fragrance after the Wederbetwoeren, does not occur in the application of ordinary detergents or cleaning agents, i. It is usually not expected that a towel exudes fragrance as soon as it is moistened again.
• Another advantage lies in the improvement of the absorption of fragrances from aqueous, preferably surfactant-containing solutions on the treated objects, in particular textiles. This not only affects the fragrances introduced via the reaction products according to the invention, but also benefits the other fragrances which are not introduced into the system via the reaction products according to the invention. This allows for improved efficiency in fragrance use.
• Another advantage lies in the improved fixation of fragrances on soft and hard surfaces, such as textiles, skin and hair or hard surfaces. With improved fixation here is meant an improved, so strong adhesion of the already scented on the objects fragrances.
• Bad-odor components are volatile compounds with kakosmophoren groups, eg. As amine derivatives and sulfur derivatives.
• the present invention can afford not only a targeted release of fragrances, but also a recording and thus reduction of malodors.
