Definitions

  • the present invention relates to a washing composition
  • a washing composition comprising a surface-active agent and a builder as basic components, and at least one compound selected from specific compounds added to the basic components, which washing composition serves to improve washing performance particularly when acting at lower temperatures and excluding phosphate from the builder for energy- saving and anti-pollution, and is mainly used for industrial purposes.
  • washing agents generally comprises surface-active agents from at least one of anionic, non-ionic, cationic or amphoteric agents and a builder (including chelating agents) including inorganic or organic salts with an alkaline property, and enzymes, bleaching agents, fluorescent agents, anti-corrosive agents, solubilization agents, solvents or the like are added thereto if desired.
  • a builder including chelating agents
  • enzymes, bleaching agents, fluorescent agents, anti-corrosive agents, solubilization agents, solvents or the like are added thereto if desired.
  • washing agents are selected according to their intended use at a washing concentration of 1 to 100 g/l and a washing temperature of 10 to 80°C.
  • high-temperature washing 70 to 80°C or extension of washing time may be required.
  • Customary builders including sodium tripolyphosphate are used on account of their excellent performance.
  • sodium tripolyphosphate contained in waste water is discharged into a river, lake of sea region, extraordinary breeding of plankton results in contamination by over-nourishment in the river, lake or sea region. Accordingly, the development of a washing agent having a strong washing performance using a builder which does not include sodium tripolyphosphate has been desired, but not yet realized.
  • a washing agent according to the present invention comprises basic components including a surface-active agent and a builder together with at least one compound selected from dithionites, compounds having a sulfino group or salts thereof, hydrazine compounds, dihydroxy phenols, diketones and derivatives of-sugars.
  • a washing composition according to the present invention can provide a strong washing effect in a low temperature region (10 to 50°C) even if the builder does not contain sodium tripolyphosphate, and thereby it contributes to energy- saving and anti-pollution.
  • a preferred washing composition according to the present invention is usually composed of the following components : (wherein wt% is inner percentage) (in the case of hydrosulfite (Sodium dithionite) 1 to 20 wt%).
  • the above mentioned surface-active agent is selected from one or more surface-active agents generally used such as anionic, non-ionic, cationic and amphoteric agents as hereinafter described. Not only the surface-active agents shown as examples but also other various agents acting similarly may be used.
  • the surface-active agent is incorporated in the composition in the above mentioned amount. If the amount is less than 0.5 wt%, the washing effect cannot be substantially obtained; if it is more than 40 wt%, an excessive amount of surface-active agent in aqueous solution may cause salting out, with resultant decrease in the cleaning effect.
  • the amount of surface-active agent incorporated is 1 to 35 wt%.
  • the builder is formed as a combination of agents selected from common inorganic salts, caustic alkalis and salts of organic acids as exemplified hereinafter and adjusted so that the aqueous solution of the builder as a whole becomes alkaline.
  • the builder is incorporated in the above mentioned amount. If the amount is less than 45 wt%, the washing agent cannot be prevented from coagulating; if it is more than 98.5 wt%, the relative amount of the surface-active agent becomes too small for performance of the washing agent.
  • the preferred amount of builder incorporated is 50 to 95 wt%.
  • the specific additive compound is selected from (1) dithionites, (2) compounds having a sulfino group or salts thereof, (3) hydrazine compounds, (4) dihydroxy phenols, (5) diketones, (6) compounds derived from sugars.
  • Any specific additive compound serves to improve significantly the effect of the cashing agent consisting of surface-active agent and builder, dissolved in water and to extend the peak of the washing effect towards a lower temperature region as hereinafter described by way of examples.
  • the harmless material means molecules or ions of builder, surface-active agent, and water in the washing liquid.
  • a specific additive compound according to the present invention co-operates with the builder and surface-active agent. At first, it strongly supports the function of emulsification, solubilization dispersion or the like as washing factors, whereby oily contamination is liable to be washed away and the oil layer adhered on the metal surface gradually becomes thin.
  • the metal surface has a layer of soil adhered by means of chemical or physical adsorption as hereinbefore described. It often occurred with conventional washing agents that the adsorption layer could not be removed well.
  • the specific additive compound, builder and-surface-active agent which newly cover the surface of the substance to be cleaned in the abovementioned manner, make the substance surface hydrophilic and prevent the soil particles from adhering again. Thus the washing is completed.
  • the amount of the specific additive incorporated depends on the washing object (the sort of soil) and the washing temperature, and generally has a value ranging from 0.5 to 30 wt% (1 to 20 wt% for hydrosulfite(sodium dithionite)). If the amount is less than the lower limit value, improvement of the required washing effect is not obtained in comparison to non-addition; if it is more than the upper limit value, improvement is scarcely obtained and, on the contrary, reduction of the washing effect may occur on account of problem in solubility or the like.
  • the total amount incorporated of additive compounds consisting of two or more components is 1 to 40 wt%.
  • the reason for the numerical limitation is similar to that for the abovementioned one-component specific additive compound.
  • a specimen is prepared by cleaning cold rolled steel sheet (100mm x 50mm x 0.6mm t) with trichloroethylene solvent, applying various sorts of oil to be washed away from the steel sheet surface, and heating the oil at 60°C for 36 hours (at room temperature for 10 days in embodiments 6 to 9 and comparing examples 6 to 7).
  • Each specimen in the embodiments and comparing examples is immersed in an aqueous solution containing a washing agent of concentration 40g/litre at a prescribed temperature for a prescribed time. After rinsing with water, it is further immersed in an aqueous solution of dilute sulfuric acid of 0.5 wt% and allowed to stand at room temperature for 30 minutes whereby the washed portion is rusted.
  • the ratio of area of th 3 rusted portion versus the total area of the specimen is visually inspected and designated as the washing ratio in %.
  • Each value of the washing ratio (%) in the tables is a mean value of the test results of the washing ability measurement performed 5 times.
  • washing agent for shown in Table 1 washing condition ... 45°C for 2 minutes oil to be washed away ... press working oil No.620 for plastic machining (tradename, manufactured by Nihon Kosakuyu Co., Ltd.)
  • Test results are shown in the graph of Fig. 1. It is seen from the figure that the washing effect of comparing example 3 (high-temperature type A) at 80°C can be equally achieved by embodiment 5 at 30°C, and that embodiment 5 is significantly excellent in washing performance in comparison with comparing example 5 (low-temperature type C) and permits practicable washing in a low temperature region.
  • the washing temperature can be decreased from 80°C to 30°C by using embodiment 5 in place of comparing example 3, it is estimated that the heating cost is reduced by about 69 x 10 3 yens per month or 830 x 10 3 yens per year when a washing vessel of 1,000 liters is used and the cost of a heavy oil is 80 yens/liter.
  • the washing agent comprises the following basic constitution and the specific additive compound shown in Table 3 is added in a prescribed incorporating amount. Washing conditions and oil to be washed away are also shown in Table 3.
  • Comparing example 8 is a conventional washing composition (high-temperature type) and constituted as follows:
  • a washing temperature ranging from 70 to 80°C is required in order to attain a washing effect similar to embodiments 10 to 66 at 30 to 50°C.
  • the washing agent is constituted as hereinafter described.
  • Table 4 shows types of specific additive compounds (1) and (2) or other compounds. Washing conditions and oil to be washed away are also shown in Table 4.
  • composition of washing agent Embodiment 5 composition of washing agent Embodiment 5;
  • a washing temperature ranging from 70 to 80°C is required in order to attain a washing effect similar to embodiments 10 to 66 at 30 to 50°C.
  • the washing agent is constituted as hereinafter described.
  • Table 4 shows types of specific additive compounds and (2) or other compounds. Washing conditions and oil to be washed away are also shown in Table 4.
