The effect of 2% niacinamide on facial sebum production
Journal of Cosmetic and Laser Therapy, 2006The presence of sebum on the face is responsible for both facial shine and the formation of comedonal and inflammatory acne lesions. Sebum control is a goal of many OTC skin care products; however, most currently available products function by absorbing sebum from the face rather than modulating its production.To demonstrate the effect of topical 2 ...

Metabolism of Niacin and Niacinamide in Perfused Rat Intestine
The Journal of Nutrition, 1979The metabolism of [14C]nicotinic acid and [14C]nicotinamide by perfused rat intestine was studied by analyzing the 14C-products formed at various time intervals after these substrates were administered intravascularly or intralumenally. Intermediates in the Preiss-Handler pathway contained isotope when [14C]nicotinic acid was administered by either ...

Use of column switching for the determination of niacinamide in compound feed
Journal of Chromatography A, 1990A high-performance liquid chromatographic method is described for the determination of niacinamide in compound feed. The niacinamide is extracted with 0.2 M hydrochloric acid in order to suppress the hydrolysis of the niacinamide to nicotinic acid. The chromatography is carried out with the aid of column switching.

Niacinamide transport through the blood-brain barrier
Neurochemical Research, 1987The unidirectional influx of niacinamide across cerebral capillaries, the anatomical locus of the blood-brain barrier, was measured with an in situ rat brain perfusion technique employing [14C]niacinamide. Niacinamide was transported rapidly across the blood-brain barrier by a system that was not saturable with 10 mM niacinamide in the perfusate ...
