Until recently it was believed that blocking UVB radiation and sunburn were the only measures needed to prevent sun damage. The SPF rating was developed to measure the ability of a sunscreen to block UVB radiation. Now we know that UVA radiation also contributes significantly to damaging the skin. But if that's what you want....
PABA
PABA, or para-aminobenzoic acid, came on the market in in the early 1970's and was the first true sunscreen to be generally available. It provides effective protection in the range of 260-313 nm. It is not used much in sunscreen formulations now because it frequently caused allergic reactions.
PABA Esters
The PABA esters are padimate O, padimate A, and glyceryl aminobenzoate.These compounds are chemically similar to PABA and provide effective protection in the range of 260-315 nm. The use of these formulations has declined with the popularity of the "PABA-free" claim.
Cinnamates - as you alreday know....
Octyl methoxycinnamate and cinoxate are cinnamates, derivatives of cinnamon that provide protection in the range of 280-310 nm.
Salicylates
The salicylates are homomenthyl salicylate, octyl salicylate, and triethanolamine salicylate. Salicylates have been used for a long time, even before PABA, and provide effective protection in the range of 290-315. They are weaker UVB absorbers than PABA and are generally added to other formulations to boost the SPF.
