Frankly as a retired chemist I'd be more likely to believe this if they explained what miracle additive they are using. Otherwise it sounds like marketing BS. DEF is plain and simple 35% Urea
I'm with you, if there was some super special ingredient it would have to be cited in the SDS......and there is no mention of any components in the mixture other than 33% Urea and 67% water. There can be no additives that create the "Advanced System Shield" because by law they would have to appear in the SDS.
The ONLY thing that might make sense is if they have simply reduced impurities in the mixture :h I haven't seen an elemental analysis of DEF deposits, but I suppose it's possible if there are mineral salts present in cheap DEF that they could crystalize and build up over time. Or there could be a reaction with trace metals and the urea that occurs under heat that forms crystals. IF I had to guess I'd say the Platinum product just uses a higher purity water source like double distilled water instead of reverse osmosis water. Or, maybe they use a higher purity urea when making the DEF solution.
The description says "prevents future deposits" so if you already have chunks in your exhaust this new product will not dissolve them.
As for the production of urea, as you stated, it's a synthetic process and is described here: Urea Production Process
