| (1)Safety of chemical |
Safety of chemical is confirmed based on the SEK standard(Oral toxicity,
Mutagenicity, Skin irritation).
SEK: Japan Textile Evaluation Technology Council |

(2)Safety of carpet after deodorization of formaldehyde |
| A quantity of free formaldehyde of the carpet after deodorization of formaldehyde
was less than the regulated index(75 μg). |
| Sample |
Quantity of free formaldehyde |
| TripleFresh Non-treated carpet |
less than limit of detection(20μg/g) |
| TripleFresh treated carpet |
less than limit of detection(20μg/g) |
|
The above chart shows that TripleFresh non-treated carpet does not contain
any material which generates formaldehyde and that we cannot detect formaldehyde,
as formaldehyde was changed into other safe chemicals by chemical reaction
of the TripleFresh treated carpet.
