Summary of the invention
The present invention is intended to overcome above-mentioned the deficiencies in the prior art, provide a kind of safe, nontoxic, non-stimulated, having no side effect does not have corrosion substantially to the washing machine stainless steel inner bag; Washing is outstanding, strong detergency, easy to use, can also kill disinfecting detergent powder of streptococcus aureus, intestinal bacteria and poliovirus and preparation method thereof.
According to disinfecting detergent powder provided by the invention, its weight percent content is:
A. tensio-active agent: 5%-50%
B. washing assistant: 5%-80%
C. additive: 0.01%-10%
D. sterilizing agent: 5%-25%
The present invention also has following additional technical feature:
Described tensio-active agent comprises anion surfactant and nonionogenic tenside.
Described anion surfactant is Sodium dodecylbenzene sulfonate or sodium alkyl sulfate or fatty alcohol-polyoxyethylene ether or its two above mixing.
Described nonionogenic tenside is fatty alcohol-polyoxyethylene ether (n=9) or nonyl phenol polyethenoxy ether.
Described washing assistant is SPC-D or Sodium peroxoborate or yellow soda ash or water glass or sodium sulfate or tripoly phosphate sodium STPP or its two above mixing.
Described additive is Xylo-Mucine or Sumizyme MP or amylase or essence or its two above mixing.
Described sterilizing agent is trichloroisocyanuric acid or Surchlor GR 60 or its both combination.
A kind of method for preparing disinfecting detergent powder, at first with the riddler screening respectively of solid material in tensio-active agent, washing assistant, the additive, the block raw material that will sift out is then sent into pulverizer and is pulverized; Secondly, take by weighing each raw material for standby successively by formula ratio; Once more standby anion surfactant, washing assistant, additive are mixed and stir; At last, through aging, more standby nonionogenic tenside added stirrer mixing stirring and get final product.
Since adopted washing powder safety that technique scheme, the present invention make, nontoxic, non-stimulated, have no side effect, the washing machine stainless steel inner bag do not had corrosion substantially; Washing is outstanding, strong detergency, easy to use, can also kill streptococcus aureus, intestinal bacteria and poliovirus.Disinfectant detergent powder of the present invention can be widely used in family, hotel, hospital, railway, airport, passenger steamer, school and almost all trades and professions washing, decontamination and sterilization and disinfection, for preventing disease infects, play immeasurable effect.

The preparation method of embodiment one to four
At first with the riddler screening respectively of solid material in tensio-active agent, washing assistant, the additive, the block raw material that will sift out is then sent into pulverizer and is pulverized; Press formula ratio and manufacturing technique requirent, with Sodium dodecylbenzene sulfonate, tripoly phosphate sodium STPP, trichloroisocyanuric acid and/or Surchlor GR 60, add successively to mix in the stirrer and stirred 10 minutes, and then add yellow soda ash, SPC-D, sodium sulfate, Xylo-Mucine successively and mix and stirred 20 minutes, add fatty polyoxyethylenated alcohol (n=9) after aging again and add stirrer, mix and stirred 10 minutes.
The washing powder that the present invention makes is through the Guangdong Prov. Disease Prevention-control Center verification test, and its experimental result is as follows:
1, poliovirus inactivating efficacy
Show through 3 revision tests: when 20 ℃~22 ℃ of test temperatures, this sterilizing agent available chlorine content is 294.1mg/L (0.34% diluent), and effect 5min, 10min, 15min are to average deactivation logarithmic value>4.00 of ridge ash virus.(seeing following table for details).
Cell contrast: cell well-grown.
2, to staphylococcus aureus and colibacillary killing effect
Negative control: diluent, the equal asepsis growth of substratum.
Conclusion: under test conditions, this disinfectant detergent powder available chlorine content is 294.1mg/L (0.34% diluent), and effect 10min is to staphylococcus aureus and colibacillaryly on average kill logarithmic value all>5.00.
3, to the corrosion of metal degree
This disinfectant detergent powder available chlorine content 294.1mg/L (0.34% diluent), erosion rate to stainless steel, carbon steel, aluminium, copper is 0.0064mm/a, 0.3454mm/a, 0.0138mm/a, 0.0127mm/a, and extent of corrosion is respectively does not have burn into moderate burn into mild corrosion, mild corrosion substantially.
4, acute oral toxicity test
After the contamination, do not find that in the observation period mouse has poisoning manifestations and death, observations sees the following form.
This disinfectant detergent powder is to acute oral toxicity LD50>5000mg/kg BW of female male NIH mouse, the nontoxic level in true border.
5, to clothing cloth sterilisation effect test in place conclusion
This disinfectant detergent powder available chlorine content is 294.1mg/L (0.34% diluent), and effect 10min is 2.68 to the logarithmic value of on average killing of the cloth of clothing surface natural bacteria, the killing logarithmic value and be of each test>1.00.
6, intact skin irritant test
In observation period, tried the not abnormal response such as show spot oedema of new zealand rabbit skin, also do not found other symptom, the highest stimulation index=0.0 (seeing the following form).
These disinfectant detergent powder working instructions 5 times of concentration solution of high working concentration stimulate the once contact intact skin of new zealand rabbit and belong to nonirritant.
7, to the mouse polychromatic erythrocytes micronucleus test
Annotate: compare with negative control group
*Expression P<0.01
The result is negative for this disinfectant detergent powder mouse polychromatic erythrocytes micronucleus test, does not find that this given the test agent has mutagenesis to somatocyte.
Above-mentioned experimental data and result show, the disinfectant detergent powder safety that the present invention makes, nontoxic, non-stimulated, have no side effect, the washing machine stainless steel inner bag do not had corrosion substantially; Washing is outstanding, strong detergency, easy to use, can also kill streptococcus aureus, intestinal bacteria and poliovirus.Disinfectant detergent powder of the present invention can be widely used in family, hotel, hospital, railway, airport, passenger steamer, school and almost all trades and professions washing, decontamination and sterilization and disinfection, for preventing disease infects, play immeasurable effect.
The foregoing description is only for the usefulness that the present invention is described; and be not be to the invention restriction; the those of ordinary skill in relevant technologies field; under the situation that does not break away from the spirit and scope of the present invention; can also make various variations and modification; therefore all technical schemes that are equal to also should belong to the category of invention, and scope of patent protection of the present invention should be limited by each claim.
