Ah ok, maybe what I need to research is the whole "cross linking" polymer subject. Sounds like that's what you're talking about.
I'm also in the process of getting an ingredient from Mayzo that is a UV absorber. Can anyone shed some light on what the Dr. was talking about in this paragraph?
"Solid BLS-531 at 0.2-0.5% loadings is a typical UVA Liquid BLS-1130 at the same loading is also good.
BLS-292 is a good HALS free radical trap the would be synergistic with the above..."
I get the UVA part, but then he went on to talk about a good "HALS free radical trap". I have no idea what that is but sounds cool
