Alkanes, C10–C20, Branched and Linear

Alkanes C10–C20 branched and linear (CAS 928771-01-1) is a refined aliphatic petroleum cut — essentially a cleaner-burning, lower-aromatic kerosene fraction. At 1–3% in a formulation it serves as a viscosity and solvency modifier, not a primary cleaning active. The ingredient is REACH-registered and considered relatively benign at the ingredient level when stripped of aromatic content. The classification profile depends on the specific cut. Highly refined versions with very low aromatic content may avoid the H304 aspiration classification that applies to the broader petroleum-distillate family. The version used in mainstream consumer degreasers typically defaults to the same H304 classification as its sibling distillates because regulatory caution treats the family conservatively. For users: not a meaningful health driver at the 1–3% level seen in this product. The chemistry of concern in solvent degreasers is the dominant aromatic-and-aliphatic fractions, not these refined alkane co-solvents.
