Therefore most of the ingredients are strictly controlled. Be careful when choosing as sunscreens. If they contain benzophenone-3 and benzophenone-4, which are more dangerous. In particular, it must contain Octyl dimethyl PABAas research has shown that this substance has a carcinogenic effect. b) UV Blocking: Sun protection by the application of physical security, but nofacil to produce, it clot.
Blockers of the safest and most effective are zinc oxide and titanium dioxide. 3. Ingredients: good sunscreen products should contain antioxidants and free radical scavengers.

Figure 78 shows the outline of the absorption process in which the gas is in contact with a countercurrent in light oil through an absorber tower. The contact in the tower can be through food or packaging. The gas entering the cold tower to report an improved removal of the components of interest. The oil used to make the removal of the tower comes from the top and is known as oil-poor, out of the tower, on the bottom carries the components removed and the gas is known as a rich oil. The gas leaving the absorber tower is basically methane and is known as residual gas. The rich oil that comes from the absorber passes a column stabilization in this case, releasing the oil-rich ethane and methane, which was unable to leave the absorber, in this case is not seeking ethane. When ethane is needed, the oil becomes a rich desmetanizadora and the fluid that comes out of it goes to a desetanizadora. Reflux in desentanizadora is to improve the separation of methane and ethane.
