Common Name(s): Neo heliopan e1000,isoamyl methoxycinnamate
DESCRIPTION
What It Does: Provides uvb cinnamate filtration as an alternative to octinoxate with different aesthetic properties.
Why It's Used: Cinnamate alternative to omc for formulations seeking different aesthetics or regulatory differentiation within the cinnamate uv filter class.
How It Works: Cinnamate chromophore absorbs uvb (λmax 308nm) via same pi-pi* mechanism as omc. isoamyl ester provides different viscosity and spreadability vs ethylhexyl ester. requires photostabilisation as with omc.
Typically Found In: European sunscreens

SCIENTIFIC NOTE
The structural isomery between isoamyl (3-methylbutyl) and 2-ethylhexyl esters of the same cinnamate chromophore provides formulation property differentiation: isoamyl's more linear chain vs ethylhexyl's branched chain provides different molecular packing and viscosity, enabling different aesthetic formulation opportunities while maintaining equivalent uvb filter activity from identical chromophore chemistry.
