Aminoalkyl substituted alkylphenol

  • Nonionic surfactants
  • CAS proprietary-mixture

Aminoalkyl substituted alkylphenol (CAS proprietary-mixture) appears in 1 of the 2,122 car-care products CarCareTruth tracks (as of August 2026).

Proprietary CAS; classified at the ingredient level in SDS §3 as STOT SE 3 (H335, respiratory irritation) at 1–5%wt. In the STP Complete Fuel System Cleaner mixture this H335 appears only at ingredient level, not in the §2 mixture-level classification, so it does not drive a mixture-level respiratory PPE tier. Not independently evaluated in public toxicological literature under this generic class name.

Aminoalkyl substituted alkylphenol is a proprietary detergent/dispersant class used as a co-active in fuel system cleaner concentrates. Alkylphenols reacted with an aminoalkyl group produce fuel-soluble, nitrogen-bearing surfactants that help keep loosened deposits suspended in the fuel and assist deposit control on fuel lines and tank surfaces.

In the STP Complete Fuel System Cleaner SDS (Energizer ENR 5569 v7.0), this component appears at 1–<5%wt with an ingredient-level classification of STOT SE 3 (H335, respiratory irritation). That H335 is an ingredient-level classification only — it does not appear in the SDS §2 mixture-level hazard classification for the finished product, so it does not by itself force a mixture-level respiratory-PPE tier. The CAS number is held proprietary in the US SDS, and no independent toxicological literature exists for this generic class name.
