This invention discloses a sustainable fuel digital tracer system, comprising at least two chemical tracers added at predetermined concentration ratios, which constitute a unique identification code for each batch of fuel. The at least two chemical tracers are selected from methoxyacrylate compounds, or at least one is selected from methoxyacrylate compounds, with the remainder selected from at least one of benzoate compounds, p-hydroxybenzoate compounds, and sorbate compounds. The tracers of this invention are all pure organic small molecules free of metals and halogens, achieving "harmless passage" to the engine after combustion. This system can accurately decode fuel at low concentrations, possesses excellent cross-fuel versatility, and cleverly meets the shelf-life requirements of marine fuels, achieving low-cost, high-precision fuel authenticity verification and accurate traceability.

The present invention relates to a solid oral pharmaceutical composition that includes: (a) an active pharmaceutical ingredient; (b) a nitrosamine inhibitor that includes linear or branched C1-C10 alkyl 3,4,5-trihydroxybenzoate; and (c) a pharmaceutically acceptable excipient. At least one of: (i) the active pharmaceutical ingredient includes at least one covalently bonded amine group that is subject to conversion to nitrosamine; or (ii) the solid oral pharmaceutical composition includes at least one amine, that is other than the amine group covalently bonded to / within the active pharmaceutical ingredient, and which is subject to conversion to nitrosamine. The nitrosamine inhibitor is present in an amount at least sufficient to reduce the amount of nitrosamine formed in the solid oral pharmaceutical composition, compared to the amount of nitrosamine formed in a comparative solid oral pharmaceutical composition that is free of the nitrosamine inhibitor.

A stabilized polymeric composition is disclosed comprising an organic polymeric material to be stabilized and a stabilizer composition comprising: at least one inorganic UV blocker, at least one hindered amine light stabilizer compound, at least one hindered phenol antioxidant compound, at least one phosphite or phosphonite compound, at least one thioester, and at least one flame retardant, wherein the stabilizer composition provides effective ultraviolet (UV) light stability, thermal stability, and gas fade resistance to the stabilized polymer even when hindered hydroxybenzoic acid esters, organic UV absorbers, acid scavengers, and / or dialkylhydroxylamines are not present.
