Mechanistic Description of Photochemical Oligomer Formation from Aqueous Pyruvic Acid [PDF]

Journal of Physical Chemistry A, 2017
The aqueous phase photochemistry of pyruvic acid, an important oxidation product of isoprene, is known to generate larger oligomeric species that may contribute to the formation of secondary organic aerosol in the atmosphere.

Size-Dependent Sigmoidal Reaction Kinetics for Pyruvic Acid Condensation at the Air-Water Interface in Aqueous Microdroplets. [PDF]

J Am Chem Soc, 2023
The chemistry of pyruvic acid (PA) under thermal dark conditions is limited in bulk solutions, but in microdroplets it is shown to readily occur. Utilizing in situ micro-Raman spectroscopy as a probe, we investigated the chemistry of PA within aqueous ...

Pyruvic Acid Peels for the Treatment of Photoaging

Dermatologic Surgery, 2004
Pyruvic acid (CH3-CO-COOH), an alpha-keto-acid, has been recently used as a medium chemical peeling agent in subjects with inflammatory acne, moderate acne scars, greasy skin, actinic keratosis, and warts.The aim of our study was to evaluate the efficacy and tolerability of 50% pyruvic acid on moderately photodamaged facial skin.We treated 20 patients ...
