Placeholder. Story frame: BASF's Tinosorb / Uvinul / Tinomax CC portfolio and L'Oréal's Mexoryl / Netlock family are the two supply-side engines behind most of what shows up as a "proprietary filter system" on brand packaging. Consumer brands compete on formulation elegance and marketing — the underlying UV chemistry is largely a two-horse race. Map the licensing tree and the branding fog thins fast.
