Animal Experiments For Cosmetics And Household Products

Better Essays

Almost every type of human or animal cell can be grown in the laboratory. Animal experiments for cosmetics and household products continue even though non-animal tests are widely available. Instead of measuring how long it takes a chemical to burn the cornea of a rabbit’s eye, manufacturers can now drop that chemical onto cornea-like 3D tissue structures produced from human cells. Likewise, human skin cultures can be grown and purchased for skin irritation testing. Scientists have managed to coax the cells to grow into 3D structures, such as miniature human organs, which can provide a more realistic way to test new therapies.
Testing cosmetic products on animals is not effective and is dangerous to the animals. There are more effective alternatives to the tests that are performed on animals. In Vitro International’s Corrositex (synthetic skin) can provide a chemical corrosivity determination in as little as three minutes to four hours, unlike the experiments on animals which often takes two to four weeks.
Crude skin allergy tests in guinea pigs only predict human reactions 72% of the time. But a combination of chemistry and cell-based alternative methods has been shown to accurately predict human reactions 90% of the time. The standard test on pregnant rats to find out if chemical or drugs may harm the developing baby can only detect 60% of dangerous substances. But a cell-based alternative (EST) has 100% accuracy at detecting toxic chemicals.
