Effects of Platinum nanoparticles

 

Safety of Platinum nanoparticles

 

Test results

1. Excellent anti-bacterial/Anti-viral effects

 

After 18 hours of treatment with the platinum nanoparticle solution, most of bacteria and viruses were eliminated.

 

Testing institution: Kitasato Research Center for Environmental Science

Subject Test results
Influenza virus 99.80%
Norovirus 99.90%
O-157 E. coli 99.90%
O-111 E. coli 99.90%
Foot-and-mouth disease virus (FMDV) 99.80%

[Anti-bacterial]
Platinum nanoparticle is proved to have anti-bacterial effect against E. coli, Staphylococcus aureus, Klebsiella pneumoniae, MRSA in the test.

[Anti-viral] 
Effective against viruses. Not only prevents virus invasion, but also supress the activities of virus themselves to inactivate them.
Highly effective against norovirus and influenza A that have currently been spread.

 

2. Excellent deodorizing potential

   

Testing institution: BOKEN Quality Evaluation Institute

  PT nano  Acceptance criteria for distribution of products with deodorant treatment
Formaldehyde 97 70
Acetic acid 99 80
Hydrogen sulfide 99 70
Pyridine 90 70
Trimethylamine 99 70
Ammonia 99 70
Isovaleric acid 99 85
Indole 95 70

 

[Deodorizing]
Not hiding odors with a flavor, the platinum nanoparticle solution radically decomposes odors with platinum, does not contains flavor, and is odorless.

 

3. Excellent anti-oxidative potential

 

[Antioxidative potential for foodstuff (verified with fruits and vegetable)] Dpph Unit/g
Platinum nanoparticle 58000
Catechinic acid 16000
Vitamin C 5400
Black tea 1700
Roasted tea 1300
Instant coffee 650
Lemon 5

 

[Keeping freshness and antioxidative performance]
The catalytic property of platinum eliminates active oxygen.
Unlike other existing antioxidative materials, platinum is highly effective against all active oxygen spieces and eliminates active oxygen semipermanently as long as it is in the body.
Used for cosmetics and supplements.

 

4. Excellent safety profile

 

   

Testing institution: Life Science Laboratories, Ltd.

Test name Results (Whether or not to meet the criteria)
Cytotoxicity study Meets the criteria
Oral toxicity test Meets the criteria
Skin primary irritation test Meets the criteria
Skin sensitization test Meets the criteria
Skin patch test Meets the criteria
Bacterial Reverse Mutation Assay (Ames assay) Meets the criteria

 

[Safety]
The safety of platinum nanoparticles has already been confirmed in toxicity studies including oral toxicity test, patch test, skin primary irritation test, skin sensitization test, cytotoxicity test, and Bacterial Reverse Mutation Assay (Ames assay).
Platinum itself is approved as a food additive by the Japanese authorities, which is also an advantage.
