Definitions

  • the present invention relates to the use of certain fragrances in hypochlorite-containing bleaches to avoid the unpleasant odor of such agents on human skin, particularly on the hands which has come in contact with the agent.
  • Efficient cleaning is one of the requirements that influences the acceptance of such agents by the consumer. This requires providing agents with a wide stain removal potential which can remove, for example, oily and greasy soils from fabrics or hard surfaces such as tiles or tiles.
  • hypochlorite bleach containing agents have been developed, among others, in which hypochlorite, as a strong oxidant, contributes to the chemical degradation, destruction and removal of soils.
  • Another advantage of using hypochlorite is that it acts as an effective disinfectant.
  • a disadvantage is felt that after contact with human skin, which inevitably results in the use of such agents with bare hands and otherwise, for example, when using gloves, can not always avoid a sticking to the skin smell, which can not always be removed even after repeated washing with water.
  • EP 0 606 707 describes agents which contain a polymer component together with a hypochlorite compound and lead to a reduction of malodors of the actual agent as well as the surfaces cleaned therewith. This could be due to the high viscosity of these agents, so that compounds responsible for the offensive odor may be trapped in vesicles.
  • EP 0 812 909 A1 describes the use of polycarboxylate polymer in hypochlorite-containing bleaches to avoid unpleasant odors resulting from the contact of such agents with skin surfaces.
  • EP 0 622 451 deals with the task of odor formation during and after applying chlorine-containing agents and suggests to use a perfume.
  • Hypochlorite-containing bleaches containing diphenyloxide and other fragrances are made EP 0 867 503 A2 .
  • the present invention is the use of fragrances to reduce the odor of chlorine bleach on human skin, which has come into contact with said chlorine bleach, the fragrance is selected from the group comprising mixtures of diphenylmethane with diphenyl oxide and mixtures of diphenylmethane with diphenyl oxide and with 2-methyl-naphthyl ether, wherein the weight ratio of diphenylmethane to diphenyl oxide is from 1: 1 to 1:50.
  • the skin is on a human hand.
  • the fragrance preferably has a combination of diphenylmethane and diphenyl oxide in a weight ratio of 1:10 to 1: 5. It furthermore preferably has a combination of diphenylmethane and 2-methylnaphthyl ether in a weight ratio of 50: 1 to 1:10, in particular from 5: 1 to 1: 1. It is also preferred if the fragrance has a combination of diphenyl oxide and 2-methyl-naphthyl ether in a weight ratio of from 250: 1 to 1: 1, in particular from 50: 1 to 5: 1.
  • Said fragrance as such or in the form of a preparation containing it, may be applied after the use of the chlorine-containing agent on the skin areas which have come into contact with said agent.
  • the fragrance is already part of the composition containing the chlorine bleach.
  • the composition is preferably an aqueous liquid which is used undiluted or, if appropriate, after mixing with water on a textile or hard surface and which contains from 0.5% by weight to 10% by weight, in particular from 1% by weight to 6% by weight .-%, of alkali metal hypochlorite, especially sodium hypochlorite contains.
  • a liquid hydrous bleach containing alkali metal hypochlorite and fragrance said fragrance being selected from the group consisting of mixtures of diphenylmethane with diphenyloxide and mixtures of diphenylmethane with diphenyloxide and with 2-methyl-naphthyl ether, wherein the weight ratio of diphenylmethane to diphenyloxide is from 1: 1 to 1:50, is selected, is a further object of the invention.
  • Another object of the invention is a method for bleaching stains on textiles and / or hard surfaces, in which one uses a composition according to the invention.
  • An agent of the invention preferably contains from 0.0005% to 0.005% by weight of diphenylmethane, from 0.005% to 0.025% by weight of diphenyloxide, and / or from 0.0001% to 0.005% by weight of 2 methyl-naphthyl ether.
  • a composition according to the invention which may also be used in the context of the use according to the invention, preferably contains 0.1% by weight to 2% by weight of alkali metal hydroxide and up to 5% by weight of palladium-stable surfactant, in particular betaine and / or alkyl ether sulfate.
  • R 1 is an alkyl or alkenyl group having 6 to 22 carbon atoms or a group R 4 is CO-NH- (CH 2 ) n -
  • R 2 is hydrogen or an alkyl group having 1 to 4 carbon atoms
  • R 3 is hydrogen or an alkyl group with 1 to 4 carbon atoms
  • R 4 is an alkyl or alkenyl group having 6 to 22 carbon atoms
  • m is a number from 1 to 6 and n is a number from 1 to 3.
  • surfactants examples include C 12-18 alkyl dimethyl betaine, commercially available as coconut betaine, and C 10-16 alkyl dimethyl betaine, commercially available as lauryl betaine.
  • Another class of particularly preferred surfactants are the alkyl ether sulfates obtainable by reacting alcohols (preferably having 6 to 22 carbon atoms) with alkylene oxides, especially ethylene oxide, followed by sulfation and neutralization, especially a C 12-14 fatty alcohol ether sulfate alkoxylated with 2 equivalents of ethylene oxide , In the ether sulfates, the corresponding cation is preferably sodium.
  • Surfactants are, if present, preferably in amounts of up to 5 wt .-%, in particular from 0.01 wt .-% to 3 wt .-% in inventive compositions.
  • the preparations may additionally comprise sequestering agents, preferably alkylphosphonic acids, and among these in particular those having at least one amine oxide substituent on the alkyl group, referred to herein as amine oxide phosphonic acids, polyacrylic acids and / or polyoxyacids containing phosphono groups, which may also be in the form of their alkali metal salts.
  • sequestering agents preferably alkylphosphonic acids, and among these in particular those having at least one amine oxide substituent on the alkyl group, referred to herein as amine oxide phosphonic acids, polyacrylic acids and / or polyoxyacids containing phosphono groups, which may also be in the form of their alkali metal salts.
  • amine oxide phosphonic acids are the amine oxide based on aminotrimethylene phosphonic acid. Preferably, from 0.01% to 2% by weight of such sequestering agents are present.
  • compositions preferably contain 0.5% by weight to 2% by weight of silicate, in particular alkali metal silicate, and / or 0.1% by weight to 2% by weight of carbonate, in particular alkali metal carbonate.
