FAIN SPECIAL TENSIDE MIXTURE RESEARCH AND TEST RESULTS
The acute toxicity was researched by Van den Varden-method and mouses of CBWA-line (60 mouses). Fain tenside was dosed to mouth and internally to stomach. Average lethal dose via mouth (LD50) was 6700 mg / weight kilogram of tested animal. The test was made by using 3 different mixtures to 30 test animals.
A test of allergizing effect (active skin anaphylaxis) was made by Overt test to 500 g weight guinea pigs. The number of test subjects was 50. The test showed that Fain tenside had no allergizing effect on used dosages, which were 2,5 g, 1,2 g and 2,5 g/weight kilogram.
The result from the test was following: in the sinking test, the mass loss for pure tap water (pH 7,3) was 2,9 mg/dm and 2 for ion exchanged water. The result for undiluted (100%) Fain tenside mixture was 1,6 – in other words better than the values for tap and ion exchanged water. For diluted (50%) Fain tenside mixture, the result was 1,9 which was also better than the values for tap and ion exchanged water.
Technical Research centre of Finland (VTT) metallurgy laboratory made a test for Fain washing agent in May 1992, where the capability of Fain washing agent solutions to remove grease was measured. Fain special tenside mixture (30%) washed the material completely clear. This means in practice that Fain special tenside is very good at grease removal. It will also cause no problems on painting after cleaning.
Technical Research centre of Finland (VTT) Textile laboratory made a stain removal ability test in June 1992. Test results showed that Fain special tenside mixture had a better than average ability to remove grease and dirt.
Test method OECD-Test Guideline 301E/ 93.
Biodegradability of Fain tenside was measured between 13 January to 19 March, 1993. The method was OECD-Test Guideline 301 E. The control substance was sodium benzoate (C7H5NaO2). The results showed that Fain tenside, both undiluted, and diluted with two different sewer water, is biodegradable.
Multinational Hickson-Manro -companies tested the amount of anionic and nonionic tensides in Fain tenside mixture during year 1993. The result showed a 40-40 ratio as was predicted earlier.
The test showed that Fain 3 had no significant aquatic toxicity.
The test showed that Fain Tenside had no significant effect on the TIC-concentration.
As a result of the research, SFS commented that Fain tenside is a biologically easily and quickly biodegradable product.
Clinical tests showed that Fain 1 and Fain 3 are non-irritating according to Association internationale de la Savonnerie et de la Détergence’s guidelines (AIS guidelines for irritancy assessment, page 6) and EC classifications (Annex VI to Directive no 67/548EEC, O.J. L110, 57, 4 May 1993).
Tests were made with a liquid chromatographic determination from Fain special tenside mixture and from samples taken from washing agents manufactured from Fain tenside between 1998–2002. The tests showed that at all researched samples the amount of formaldehyde was under < 0,001 %.
An eye irritation test was made with Fain special tenside in Turku University central hospital (TYKS) according to OECD 405. The test showed that Fain special tenside is not an eye irritant.
