About

3-amino-2-butanol is a cosmetic ingredient used in product formulations. Exercise caution due to limited available safety data.

This aliphatic amino alcohol lacks aromatic ring structures and nitro groups that characterize more concerning cosmetic intermediates. It is not listed in EU Annex II or III restrictions and has a favorable toxicity profile with no reported sensitization. Available data support its safe use at current cosmetic concentrations.

Skin benefits

  • May function as pH adjuster
  • Buffering agent potential

Known concerns

  • Limited cosmetic use history
  • May contribute to nitrosamine formation if combined with nitrosating agents
