Generic name: homosalate

Brand(s): Coppertone and many others

Stability:
When exposed to sunlight homosalate undergoes some degradation. There is not enough data to judge the impact of degradation on the UVB blocking ability.

Homosalate is a salycilate (a deriative of salycilic acid). It is used to augment the UVB protection in a sunscreen. Salicylates are weak UVB absorbers and they are generally used in combination with other UV filters. It appears to have comparatively good safety profile.
