2-HEXYL-1,3-DIOXOLANE.

Optional CAS 1708-34-5 / PERFUMING

A synthetic fragrance molecule that delivers fresh, green, and fruity scent notes to skincare formulations. This dioxolane compound serves primarily as a perfuming agent and solvent, with limited direct skin benefits beyond sensory enhancement.

perfuming solvent stabilizer

Science

Functions as a perfuming agent and formulation solvent without recognized biological activity for skin improvement. Acts as a pro-fragrance component in controlled-release systems and provides stability in alkaline formulations.


Research

High confidence
Effective range 0.0026–0.32%
Optimal

0.0026%

Key findings

  1. 01 Maximum safe concentration in fine fragrances based on sensitization risk assessment
  2. 02 Safety threshold for leave-on facial products to prevent sensitization

Transparency

Not commonly dusted

Primarily used for fragrance purposes with strict concentration limits based on sensitization potential rather than efficacy dusting


The Formula

Solubility
Oil
Optimal pH 10.5 – 13.5
0 7 14

Stability

Exceptionally stable in alkaline conditions but susceptible to acid-catalyzed hydrolysis below pH 5.0 which can break the acetal ring structure

Synergies

  • cyclodextrin complexes for controlled fragrance release

Conflicts

  • strong oxidizing agents
  • acidic conditions below pH 5.0
  • Brønsted acid catalysts
