Polymeric esters |
| abstract |
The present invention is drawn to a process for improving the efficiency of sunscreens using a series of polyesters based upon sorbeth ethoxylates esterified with fatty acids, then crosslinked with dimer acid. These polyesters exhibit a synergistic interaction with sunscreen actives improving the efficiency providing a “shield” for the body from the harmful effects of the sun. These sorbitol alkoxylates are then reacted with dimer acid, resulting in a series of novel polyesters. The linking of the two spider esters together with dimer provide an amphilic macromolecule possessing both hydrophilic and hydrophobic portions covalently bonded to the same molecule, this provides both a boost in sun protection factor (SPF) and the ability for the sunscreen actives to be applied to wet skin. |
