Fain special tenside mixture research and test results
The patented Fain technology used in producing the special surfactant mixture does not cause emissions, effluents, noise or smell. It is eco-friendly and consumes only a small amount of energy. Fain technology is the basis for a whole range of diverse Fain products.
Faintend cherishes green values and is committed to protecting them. This means producing eco-friendly and in all respects safe, high quality products. Faintend technology is noise-free and odour-free, and it does not pollute the ground, air or water. Fain products do not cause irritation to the skin or other discomfort to users, and the products are biodegradeable and water-soluble. All our products are manufactured following a strictly controlled development and production process.
The easily and rapidly biodegradable Fain special surfactant mixture is achieved through dedicated and thorough basic research and product development. During the product development we have cooperated with the Tampere University of Technology, the Department of Materials Science of the University of Turku, the Lappeenranta University of Technology, and with a number of private and authorized laboratories. Several different test and analysis reports on the patented Fain technology and Fain products are available on request (COST, OECD 301E, ISO862, AISE/EC, OECD405, VTT, REACH).
The anionic surface active agent in Fain tenside mixture is secondaric triethanolamine salt of alkyl sulfonates. Its formula is [RSO3H·N(C2H4OH)3 and/or RSO3H·N(C2H4OH)2] and possibly various amont of nonionic tensides (triethanolamines and alkyl ether sulphate). At the final manufacturing stage, it is possible to add water improvement substances, biologically active substances, fragrances, preservatives, colours and clarificants, etc. Fain tenside, Fain special tenside mixture and Fain special tenside are synonyms. Fain 1 and Fain 3 are two main manufactured Fain special tenside mixtures.
1. Research: Acute toxicity/1990 number 322
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.
2. Research: Allergizing effect/1990 number 322
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.
3. Research: Sinking test. VTT (Technical Research centre of Finland) MRG52/92
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.
4. Research: Grease removing properties. MRG314/92
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.
5. Research: Stain removal ability. VTT Textile laboratory. TEX203/92
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.
6. Research: Biological degradability. Institut Fresenius, Saksa, IF-92/20179-01/93.
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.
7. Research: HPLC analysis Fain surfactant mixture, Hickson Manro Ltd, England 1993
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.
8. Test: Acute aquatic toxicity, Daphnia magna, (SFS-EN ISO 6341) result from tenside sample "Fain 3". Ekolab Environmental Oy, 1998
The test showed that Fain 3 had no significant aquatic toxicity.
9. Test: Prevention of algae growth with "Clean algae culture" ISO 8692, "Fain 3". Selenastrum capricornutum. Ekolab Environmental Oy, 1998
The test showed that Fain Tenside had no significant effect on the TIC-concentration.
10. Research: (Biodegradability of Fain tenside, SFS-Environmental label, 1998)
As a result of the research, SFS commented that Fain tenside is a biologically easily and quickly biodegradable product.
11. Test: Skin irritation test, Oy Ars Pathologiae Inc December 1999
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).
12. Test: Formaldehyde research, Customs laboratory February 2003
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 %.
13. Eye irritation test 2006
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.
14. REACH (EU-legislation)
Oy Faintend Ltd has completed the pre-registration for manufactured Fain special tenside in October 2008 required by to REACH.
