  why do you need BHT in sunscreen?

  I understand that you need BHT in retinol cream because retinol degrades. but why sunscreen?

  For example, Merck’s Eusolex® 2292 contains BHT with its UVB filter, ethylhexyl methoxycinnamate.  Ethylhexyl methoxycinnamate is a derivative of cinnamate acid  which is an unsaturated fatty acid so the BHT’s purpose is as an antioxidant to help stability.

  @ sandydijon as an antioxidant but the current trend is no BHT
