Propylene glycol is an aliphatic alcohol that functions as a skin conditioning agent, viscosity decreasing agent, solvent, and fragrance ingredient in cosmetics. Tripropylene glycol functions as a humectant, antioxidant, and emulsion stabilizer. Polypropylene glycols (PPGs), including PPG-3, PPG-7, PPG-9, PPG-12, PPG-13, PPG-15, PPG-16, PPG-17, PPG-20, PPG-26, PPG-30, PPG-33, PPG-34, PPG-51, PPG-52, and PPG-69, function primarily as skin conditioning agents, with some solvent use. The majority…

The larger data set indicates that these compounds have low sensitization potential in animal studies, and therefore are unlikely to represent human allergens, and the existing safety evaluations of the FDA, USEPA, NTP and ATSDR for these compounds are consistent and point to the conclusion that the propylene glycols present a very low risk to human health.

The in vitro model presented here is its immediate availability and reproducibility, which allows for the comparison of a large series of topical agents with respect to their cell toxicity under standardized conditions, but this single-cell model lacks some of the properties found in intact skin, such as the stratum corneum barrier, and interactions between keratinocytes and other cells,such as Langerhans cells.
