Now we have nail polish that smells of cheese! Not just any cheese, but Velveeta! If you want to call that cheese.</p> Tue, 09 Aug 2022 21:44:59 +0000 K. Coco Zhang, Student Contributor 9196 at /oss /oss/article/student-contributors-did-you-know-general-science/what-makes-perfect-polish <p>I got my nails done for my convocation ceremony. My friends and I were greeted with a number of options: basic, shellac, acrylic… not to mention the selection of colours we had to choose from as well. But the quest for a perfect manicure has far preceded last Wednesday afternoon.</p> Fri, 15 Jul 2022 11:00:00 +0000 Cat Wang 9175 at /oss /oss/article/technology/chemistry-fake-nails <p><span>Fake nails come in two major varieties:</span><a href="http://www.nailsmag.com/article/92533/secret-ingredient-acrylic-liquid"> acrylic</a><span> and</span><a href="http://www.nailsmag.com/article/91808/the-science-of-gels"> gel</a><span>. Even this distinction, though, creates an element of confusion since both of these systems actually use acrylic products. All fake nail systems require certain compounds: monomers which, when activated by an initiator molecule, combine to form polymers, as well as catalysts to make the reaction go faster.</span></p> Thu, 22 Mar 2018 19:30:00 +0000 Ada McVean B.Sc. 6966 at /oss /oss/article/did-you-know/acetone-free-nail-polish-removers <p>Some nail polish removers are advertised as containing no acetone. These products use ethyl acetate as the solvent because it has less of a tendency to dehydrate and discolour nails. Dehydration is a problem because when nails lose moisture they become brittle. The disadvantage of non-acetone nail polish removers is that they take more time to remove the polish. But investing the time pays dividends.</p> Sat, 20 May 2017 22:49:49 +0000 OSS 2460 at /oss /oss/article/health-you-asked/what-can-you-tell-appearance-our-nails <p>Nail discolouration can signal disease. Abnormally white fingernails may be due to anemia or kidney problems, deep blue nail beds signal pulmonary obstruction or emphysema, and yellow nails, while often a result of tobacco staining, may suggest liver problems, diabetes, respiratory disorders, problems with the lymphatic system, renal disease, syphilis, cancer or exposure to toxins.</p> Tue, 06 Nov 2012 18:11:19 +0000 Joe Schwarcz PhD 1761 at /oss
