Definitions
- the present invention relates to the stabilization of hypochlorite-containing liquid detergents and / or cleaning agents for hard surfaces in households, for example for cleaning tiles.
- Sodium hypochlorite is known as a highly effective bleaching agent and has been used for a long time, optionally together with soaps and / or synthetic surfactants, to remove stains and all types of soiling when washing textiles and when cleaning hard surfaces. It is usually sold in concentrations of about 2% to 10% by weight in water for household use.
- Liquid detergent preparations or corresponding preparations of cleaning agents for hard surfaces which contain hypochlorite as the bleaching component, are susceptible to loss of activity in the case of prolonged storage, in particular because of the degradation of the hypochlorite which then takes place.
- the ingredients that are desirable in washing and cleaning agents from the point of view of use or for aesthetic reasons include, in addition to the active ingredients that decisively influence the performance of such agents, in particular hypochlorite in this case, also coloring agents which are intended to give liquid preparations in particular a pleasant visual appearance.
- Dyes in particular are usually slightly oxidatively attacked by hypochlorite, so that in addition to the loss of the bleaching agent, the color impression of hypochlorite-containing liquid agents also changes rapidly during storage.
- fragrances which are attacked by the strong oxidizing agent hypochlorite in a large number of cases so that the fragrance impression of perfumed agents changes in an unacceptable manner when stored.
- the invention therefore relates to the use of p-methoxybenzyl alcohol for stabilizing hypochlorite-containing aqueous liquid compositions which contain colored metal pigment.
- a second subject of the invention is therefore the joint use of p-methoxybenzyl alcohol and an alkali iodide for stabilizing hypochlorite-containing aqueous liquid compositions which contain colored metal pigment.
- Another object of the invention is an aqueous liquid bleaching agent containing alkali hypochlorite and colored metal pigment, which is characterized in that it additionally contains p-methoxybenzyl alcohol, optionally in combination with akali iodide.
- p-Methoxybenzyl alcohol is also known as anise alcohol. It is commercially available and has so far been used, for example, as a component of fragrance.
- the liquid agent stabilized according to the invention contains 0.5% by weight to 5% by weight of alkali hypochlorite, in particular sodium hypochlorite.
- compositions are particularly suitable and very effective as cleaning agents for hard surfaces, for example for use on walls, work surfaces, floors and the like.
- the compositions particularly because of their hypochlorite content, are particularly suitable for removing soiling that occurs in kitchens or bathrooms, including the greasy soiling that can occur after the use of bathtubs, shower cubicles and wash basins.
- a bleaching agent in the form of hypochlorite is an essential component of the agents according to the invention.
- Bleaching agents in themselves are well known components of detergent compositions and are particularly successful in combating mildew and mold, soiling that can often be found in soap deposits or in association with them.
- alkali hypochlorites such as, for example, potassium hypochlorite
- chloride salts there are often considerable amounts of chloride salts contain. These can easily be used to produce agents according to the invention, so that one does not necessarily have to rely on the use of high-purity NaOCl.
- the compositions contain 0.5% by weight to 4.5% by weight, in particular 1% by weight to 4% by weight, of alkali hypochlorite.
- compositions preferably contain more than 0% by weight to approximately 0.01% by weight, in particular approximately 0.001% by weight to approximately 0.008% by weight, of colored, in particular blue and / or green, metal pigment.
- complex compounds of nickel, cobalt, cupfer, iron and / or manganese are preferred; copper phthalocyanine dyes are particularly preferred.
- the stability of both the colored metal pigment and the alkali hypochlorite is increased by the presence of alkali iodide.
- alkali iodide There is preferably more than 0% by weight up to about 0.01% by weight, in particular about 0.001% by weight to about 0.006% by weight, of alkali iodide, in particular potassium iodide.
- the agents stabilized according to the invention are normally alkaline and for this purpose can contain about 0.1% by weight to 2% by weight, in particular 0.1% by weight to 1.1% by weight, of alkali metal hydroxide.
- the preferred alkali hydroxide is sodium hydroxide, and the alkali salts, which are mentioned in connection with the other ingredients of the compositions, are preferably the sodium salts.
- the preparations can contain surfactants which are stable in the presence of the hypochlorite.
- Betaines in particular of the general formula I, are preferred,
- Examples of particularly suitable representatives of this class of surfactants include Ci 2- ig alkyl dimethyl betaine, commercially available as coconut betaine, and Ci 0- i 6 alkyl dimethyl betaine, commercially available as lauryl betaine.
- alkyl ether sulfates which can be obtained by reacting alcohols (preferably having 6 to 22 carbon atoms) with alkylene oxides, in particular ethylene oxide, and subsequent sulfation and neutralization, in particular a C 1 -C 4 -fatty alcohol ether sulfate alkoxylated with 2 equivalents of ethylene oxide .
- the corresponding cation is preferably sodium.
- surfactants are preferably present in amounts up to 5% by weight, in particular from 0.01% by weight to 3% by weight, in agents stabilized according to the invention.
- the preparations can additionally contain sequestering agents, preferably alkylphosphonic acids and among them in particular those with at least one amine oxide substituent on the alkyl group, here referred to as amine oxidephosphonic acids, polyacrylic acids and / or polyacrylic acids having phosphono groups, which may also be present in the form of their alkali metal salts.
- sequestering agents preferably alkylphosphonic acids and among them in particular those with at least one amine oxide substituent on the alkyl group, here referred to as amine oxidephosphonic acids, polyacrylic acids and / or polyacrylic acids having phosphono groups, which may also be present in the form of their alkali metal salts.
- amine oxidephosphonic acids preferably alkylphosphonic acids and among them in particular those with at least one amine oxide substituent on the alkyl group
- polyacrylic acids and / or polyacrylic acids having phosphono groups which may also be present in the form of their alkali metal salts.
- R 5 is hydrogen, a group - (CH 2 ) x (CHCH 3 ) y -NH 2 -> 0 or an alkali metal, x is a number from 1 to 4 and y is 0 or 1.
- the amine oxide is based on aminotrimethylene phosphonic acid. Preferably 0.01 wt% to 2 wt% of such sequestering agents are present.
- the preparations stabilized according to the invention can contain small amounts of one or more bleach-stable fragrances.
- the fragrance component optionally contained in addition to the anise alcohol is preferably of higher relative volatility than the constituents which are possibly responsible for a smell of bleach.
- the agents stabilized according to the invention can be prepared in a simple manner by mixing the above-mentioned ingredients in the stated amounts.
- Preparations according to the invention (II, 12) with different pigment contents and, for comparison purposes, preparations of the same composition without anise alcohol and potassium iodide (Cl, C2) were prepared by mixing the ingredients with water.
- the means were composed as follows [% by weight]:
