Petroleum jelly aid in the removal of petroleum jelly from hair and skin. In 2015 German consumer watchdog Stiftung Warentest analyzed cosmetics containing mineral oils. After developing a new detection method they found high concentrations of Mineral Oil Aromatic Hydrocarbons (MOHA) and even polyaromatics in products containing mineral oils with Vaseline products containing the most MOHA of all tested cosmetics (up to 9%). The European Food Safety Authority sees MOHA and polyaromatics as possibly carcinogenic. Based on the results, Stiftung Warentest warns not to use Vaseline for lip care or any product that is based on mineral oils. Petroleum jelly Petroleum jelly,
Egg jelly Egg jelly Egg jelly(extracellular layer", "jelly coat) is a gelatinous layer that surrounds the oocytes of many organisms and releases species-specific chemoattractants that activate and guide sperm to the oocyte. The egg jelly is located immediately surrounding the vitelline envelope and consists primarily of a network of short peptides and sulfated fucan glycoproteins. These short peptides diffuse into the surrounding area and stimulate respiration and movement of the sperm to the egg. An example of such a peptide is resact which has been studied as the primary means of attracting and orientating sperm to the eggs in sea urchins. The
