2-Aminoisobutanol

  • Bases
  • CAS 124-68-5
  • IUPAC: 2-amino-2-methylpropan-1-ol

2-Aminoisobutanol (CAS 124-68-5) appears in 1 of the 1,812 car-care products CarCareTruth tracks (as of June 2026). It is readily biodegradable.

Classified as Reproductive Toxin Cat 2 (H361) and Skin Sensitizer Cat 1A (H317) at ingredient level. Also classified as Acute Toxicity (Oral, Dermal) and Skin/Eye Irritant. At concentrations below 0.5% in consumer emulsions, the reproductive toxicity classification is carried through to the product mixture per GHS rules, triggering H361 at product level. Not currently on California Proposition 65 list.

2-Aminoisobutanol (AMP — 2-amino-2-methyl-1-propanol, CAS 124-68-5) is an amine alcohol commonly used as a pH adjuster and neutralizer in alkaline emulsion formulations. It buffers the formula to the desired pH range (typically 8.5–11.0) and stabilizes emulsion systems.

The GHS Cat 2 reproductive toxin classification (H361) at the ingredient level carries through to product mixture-level SDS §2 classification even at low concentrations per CLP/GHS mixture rules. This classification is the basis for the published_flag lifecycle state in products containing this ingredient. Not currently listed on the California Proposition 65 list. Common in Meguiar's G-series consumer products (G147, G15816).
