About

A small amino-alcohol cyclic compound used as a skin conditioning agent. Secondary amine class — nitrosamine formation is a formulation-stewardship concern.

2-Methyl-4-hydroxypyrrolidine (CAS 94134-94-8) is a small five-membered nitrogen heterocycle with a methyl and a hydroxyl substituent. As a secondary amine, it belongs to a class where co-formulation with nitrosating agents (sodium nitrite, some preservatives) can produce carcinogenic nitrosamines — a concern thoroughly studied in DEA/TEA/MEA compounds. There is no CIR or SCCS review specific to this ingredient. Public safety and efficacy data in cosmetics is limited; default-cautious scoring is appropriate. Typical cosmetic use is likely at low concentration.

Skin benefits

  • Small heterocyclic amine — potential skin conditioning
  • Possible role as pH buffer or humectant precursor

Known concerns

  • Secondary amine — potential nitrosamine formation with nitrosating agents (nitrites)
  • No dedicated CIR or SCCS review
  • Limited public safety data
  • Small-amine class generally requires tighter formulation controls
