BENZALDEHYDE GLYCERYL 1,3-CYCLIC ACETAL.

Optional CAS 1319-88-6 / PERFUMING

A sophisticated aromatic acetal that functions as a pro-fragrance, delivering a subtle cherry-almond scent profile. It is engineered to remain stable in formulation while gradually releasing skin-beneficial components upon contact with the skin's natural acidic environment.

Perfuming Pro-fragrance Delivery Precursor to Humectants

Science

Upon application, the molecule undergoes acid-catalyzed hydrolysis triggered by the skin's acidic mantle (typically pH 4.5–5.5). This controlled breakdown releases Benzaldehyde, which provides secondary antimicrobial support, and Glycerol, a primary humectant that enhances stratum corneum hydration and barrier resilience.

Key findings

  1. 01 Human patch testing confirmed zero instances of irritation or sensitization over repeated applications in petrolatum-based vehicles.
  2. 02 Threshold of Toxicological Concern (TTC) modeling indicates no safety risks regarding skin sensitization at standard industry usage levels.

As a fragrance component, it is naturally used at low concentrations. However, if a brand claims active 'hydration' or 'antimicrobial' benefits from this specific ingredient at levels below 0.05%, it is likely being used for marketing purposes rather than physiological impact.

Stability

Highly sensitive to acidic environments; formulations with a pH below 5.5 will trigger premature hydrolysis, compromising the fragrance profile and stability. It is most stable in neutral to alkaline systems like bar soaps or specific cream bases.
