Mothpaper

IUPAC Name:

Mothpaper

Test material form:

other: Paper

Details on test material:

Batch No.: LOT 07.15
Active Substance (a.s.): 0.233 % Transfluthrin
Mode of product: Paper
Packaging material: PET/PE-foil
Manufacturer: Reckhaus GmbH & Co. KG
Industriestraße 53
33689 Bielefeld, Germany
Production date: 2015-05-26
Expiry date: 2019-05-25

Specific details on test material used for the study:

The purpose of the study is to generate stability data for the test item after 48 months at 20 °C, 18 weeks at 30 °C and 8 weeks at 40 °C.

The appearance (visual), pH (CIPAC MT 75.3), weight loss, active substance content (MV122) and density (EU method A.3) will be determined before and after storage.

The stability of the packaging will be assessed before and after storage according to SOP-PR-029.

Results and discussion

Results:

The results obtained before storage are tabulated below. The study is currently ongoing and results are expected in December 2015 for the accelerated study and October 2017 for the ambient study. Study plan attached.
