Definitions
- the invention relates to an active chlorine-releasing toilet cleaning block, in particular a toilet cleaning block to be attached to the edge of the bowl and a method for manufacturing the toilet cleaning block.
- Perfume oils are solutions of various essential oils. In order to meet the ideas of consumers, the well-known active chlorine-releasing cleaning blocks perfume oils in concentrations of approx 10% used.
- EP 0462 643 B1 describes a formulation with 8% by weight of a hydrophobic, liquid perfume oil in an active chlorine-releasing toilet cleaning block suggested.
- Perfume oils are relatively expensive. When using active chlorine releasing agents together Oxidation is also common for substances and perfume oils and / or chlorination of individual or all components of the perfume oils, which is natural is undesirable.
- the object of the invention is a new active chlorine-releasing cleaning block To provide that smells nice and inexpensive to manufacture and a Specify procedures for manufacturing the cleaning and disinfection block.
- the solid fragrances are also much cheaper than perfume oils and as a result
- concentration of fragrance and / or of the synergetic smell effect can active chlorine-releasing agents compared to the known recipes for the same Odor intensity can be reduced.
- concentration of the Fragrance of the desired smell and the desired odor intensity from.
- Solid fragrance substances are understood to mean all substances that have a more or less strong smell and a melting point above 20 ° C.
- oxygen-containing fragrances are the substances which at least one aromatic together with an ester and / or ether and / or Contain carboxylic acid and / or carbonyl group, such as 4'-methoxyacetophenone (Acetanisole), benzophenone, cinnamyl cinnamate (cinnamic alcohol cinnamic acid ester), 4-acetyl-6-tert-butyl-1,1-dimethylindane, Coumarin, para-cresylphenyl acetate, methyl naphthyl ketone, Phenylacetic acid, ⁇ -trichloromethylbenzyl acetate, acetylisoeugenol, Benzyl isoeugenol, piperonylacetone, ethyl vanillin, p-hydroxyphenyl-butan-2-one, Hydroquinone dimethyl ether, ⁇ -naphthyl methyl ether, phenyle
- oxygen-containing fragrances with a cyclic aliphatic group or an aliphatic heterocycle for example maltol, ethyl maltol, 4-tert-butyl-cyclohexanol or 4-tert-butylcyclohexan-2-one can be used.
- a cyclic aliphatic group or one solid fragrances containing aliphatic heterocycle possible.
- solid fragrances containing oxygen or nitrogen are also organic degradable. Another advantage of the solid containing oxygen or nitrogen Fragrance is also that they are often non-irritating and not harmful to health are.
- the fragrances are 4'-methoxyacetophenone (acetanisole), borneol, Camphor, cedrol, isoborneol and 4-tert. Butyl cyclohexanol preferred.
- fragrances are borneol, cedrol, isobomeol and 4th.
- Butyl-cyclohexanol also as non-irritant and not harmful to health Fragrances.
- oxidation inhibitors are generally understood to mean all the substances that cause oxidation or reduce or even prevent chlorination of the solid fragrance.
- Such substances are advantageously selected as oxidation inhibitors which are used in the toilet cleaning block anyway.
- So can be used as an extrusion aid such substances can be selected that act as oxidation inhibitors Act.
- it can also act as an oxidation inhibitor Castor ethoxylate, especially castor ethoxylate with less than 80 EO, than Extrusion aids are used.
- fragrance When using the less stable against the active chlorine-releasing substance solid fragrances, it is also possible to coat the fragrance by coating or microencapsulating to protect.
- B. polyvinyl alcohol be used.

- the synergetic odor effect occurs particularly strongly when the concentration ratio between the active chlorine releasing agent and the solid fragrance between 5: 1 and 3: 1, preferably between 4.5: 1 and 3.3: 1 and in particular between 3.5: 1 and 4: 1.
- Suitable, preferred and particularly preferred ranges [% by weight] of the individual substance classes are listed in the table below: Range [wt%] Preferred range [% by weight] Particularly preferred range [% by weight] Substance class a.) 10-60 10-50 10-50 anionic surfactant b.) 0-20 0-20 0-20 nonionic surfactant c.) 0-10 0-5 0-5 amphoteric surfactant d.) 0-5 0-5 0-5 Lactobionic acid or lactobionic acid derivative e.) 20-80 40-75 40-75 inorganic salt f.) 0.5-10 1-7 3-6 solid fragrance G.) 0-5 0-5 0.5-5 colour H.) 1-30 5-25 10-20 active chlorine-releasing substance i.) 0-5 0-5 0-5 Complexing agent j.) 0-20 0-20 0-20 Rinse regulator k.) 0-40 0-40 0-40 Acid that dissolves limescale and urine l.) 0-20 0-20 0
- the block according to the invention consists of approximately 10 to 60% by weight, preferably 10 to 50% by weight, of anionic surfactant (a).
- anionic surfactant (a) those selected from the groups consisting of alkyl sulfate, fatty alcohol sulfate, fatty alcohol ether sulfate and alkylbenzenesulfonate or mixtures thereof are used.
- Alkyl chain lengths of the alkyl radicals of the fatty acid constituents of C 8 -C 18 are preferred.
- Nonionic surfactants (b) can optionally be used.
- adducts of 3 to 80 moles of ethylene oxide with 1 mole of one aliphatic compound having essentially 8 to 20 carbon atoms selected are from the group of alcohols and fatty acids.
- alkyl aromatic Compounds such as alkylphenols are suitable here.
- the proportion of non-ionic Surfactants in the agent according to the invention can be up to 20% by weight.
- amphoteric surfactants (c) use 0 to 10% by weight, preferably 0 to 5% by weight of a fatty acid amidopropyl betaine with a C 5 -C 21 fatty acid content.
- Betaine coconut fatty acid is preferably used as the fatty acid. It is advantageous that this amphoteric surfactant can be combined as desired with the anionic and optionally nonionic surfactant used in each case or the anionic and optionally nonionic surfactants.
- the cleaning block can contain 0 to 5% by weight of lactobionic acid or at least one lactobionic acid derivative (d) included.
- the total proportion of components (c) and (d) 0.5 to 10% by weight.
- Components (c) and / or (d) essentially serve as a foaming agent.
- lactobionic acid or lactobionic acid derivative as a foaming agent, the amount added can be achieved with the same foaming effect of foaming agents compared to conventional formulations by about half or reduce more.
- the agent according to this preferred embodiment can be 20 to 80% by weight inorganic Salt (s), preferably 40 to 75% by weight of an inorganic salt which is selected from the group consisting of the alkali and / or alkaline earth salts of sulfuric acid, phosphoric acids, nitrogen acids, carbonic acid or hydrochloric acid or contain mixtures thereof. This allows the consistency and rinsing behavior of the cleaning block favorably.

- rinse regulators (j) can be used. Suitable for this especially the salts of aromatic sulfonic acids, for example sodium cumene sulfonate or sodium toluenesulfonate. Dipropylene glycol can also be used for the same purpose be used. If the latter connection is used, their share of the cleaning block can even be kept extremely low. In As a rule, a proportion of up to 5% by weight is sufficient. In the field of salts the proportion of aromatic sulfonic acids is up to 20% by weight finished funds.
- aromatic sulfonic acids for example sodium cumene sulfonate or sodium toluenesulfonate.
- Dipropylene glycol can also be used for the same purpose be used. If the latter connection is used, their share of the cleaning block can even be kept extremely low. In As a rule, a proportion of up to 5% by weight is sufficient. In the field of salts the proportion of aromatic sulfonic acids is up to 20% by weight finished funds.
