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).

Molecular chaperones such as Hsp40 and Hsp70 hold the androgen receptor (AR) in an inactive conformation. They are released in the presence of androgens, enabling transactivation and causing the receptor to become aggregation-prone. Here we show that these molecular chaperones
