Auction Description

I am looking to conduct eco toxicity testing on 10-20 cosmetic ingredients for R&D purposes. Could you please provide costs for certified and uncertified laboratories for the following analyses: OECD 203 (fish toxicity) SPEC ATTACHED


The fish are exposed to the test substance preferably for a period of 96 hours. Mortalities are recorded at 24, 48, 72 and 96 hours and the concentrations which kill 50 per cent of the fish (LC50) are determined where possible.

One or more species may be used, the choice being at the discretion of the testing laboratory. At least seven fishes must be used at each test concentration and in the controls. The test substance should be administered to, at least, five concentrations in a geometric series with a factor preferably not exceeding 2.2. The limit test corresponds to one dose level of 100 mg/L. This study includes the observations of fish at least after 24, 48, 72 and 96 hours. The cumulative percentage mortality for each exposure period is plotted against concentration on logarithmic probability paper.

Please quote per cosmetic ingredient.

"I was searching for labs in the States who tested consumer products. I was unsure of where to go and how to get started. So many labs! The field was vast and overwhelming. I spoke to NameYourTestPrice.com and they understood what I needed and made excellent suggestions and provided me with helpful contacts. Thanks Name Your Test Price!"

-Maggie Gilmour, Researcher, Discovery Channel - Toronto Ontario

"When we had a need to conduct some external testing, we started by contacting local testing labs and got quotes of $500 per sample. Then we found testing partners and they were able to get the job done for $200 per sample, saving us thousands! We have been working with them for our external testing and certification needs ever since."
