General description

Propylene glycol is an aliphatic dihydric alcohol with a wide range of applications in the food industry such as an anticaking agent, antioxidant, humectant, flavoring agent, emulsifier, stabilizer, thickener etc.

Application


  • Fatally impaired glucose digestion by propylene glycol in Aedes aegypti (Diptera: Culicidae) and co-formulation with terpenoids for enhancing attractive toxic sugar baits.: This study explores the application of propylene glycol in impairing glucose digestion in mosquitoes, offering a novel approach to vector control through enhanced toxic sugar baits. The synergy with terpenoids broadens its impact, marking significant progress in pest management strategies (Maes et al., 2024).

  • Null cross-modal effects of olfactory training on visual, auditory or olfactory working memory in 6- to 9-year-old children.: This neuroscientific study utilizes propylene glycol in olfactory training exercises, investigating its potential to influence cross-modal sensory processing. Despite null findings, it provides a critical assessment of sensory integration therapies (Pieniak et al., 2024).

  • Propylene glycol toxicity in an adolescent secondary to chronic cornstarch ingestion.: This medical case study addresses the risks associated with excessive propylene glycol intake, highlighting its potential toxic effects. The study serves as a crucial reminder of the need for regulatory scrutiny and public awareness regarding chemical additives in food products (Downey et al., 2024).
