About

A specialty ingredient derived from imidazoline and isostearic acid. There's not much public info on this one, so it's scored conservatively.

Bis-Ethyl(isostearylimidazoline) Isostearamide is a dimeric imidazoline amide listed on EU CosIng with skin- and hair-conditioning functions. Imidazoline derivatives are known for their mild-to-moderate skin sensitisation potential. The bis-structural design reduces volatility but may increase molecular weight and skin retention. It is not listed on EU Annex II or III, but the SCCS has flagged imidazoline compounds for surveillance. The isostearic acid moiety improves skin compatibility compared to oleic acid-based alternatives.

Skin benefits

  • Effective hair and skin conditioning
  • Provides lubricity and soft after-feel
  • Antistatic properties

Known concerns

  • Skin sensitisation concern for imidazoline derivatives
  • Eye irritation potential
  • Limited long-term safety data in cosmetic literature
