The hidden science of haptics: A pedagogical review of tactile evaluation in cosmetics

International Journal of Cosmetic Science, EarlyView.
This review explores the physiological basis of tactile perception and critically examines classical and emerging sensory methods used in cosmetics, advocating for broader methodological integration and recognition of sensory analysis in the field. Abstract Sensory analysis is a cornerstone of cosmetic development, yet remains underrepresented in peer ...

Volatile fatty acids from axenic Ascaris lumbricoides

Archives of Biochemistry and Biophysics, 1960
Abstract 1. 1. The investigations in this study have been concerned with the separation and identification by gas-liquid chromatography of the methyl esters of volatile fatty acids excreted from axenic Ascaris lumbricoides. 2. 2. Ten methyl ester peaks, of which three were major components and seven minor components, were detected.

Human Vaginal Secretions: Volatile Fatty Acid Content

Science, 1974
Vaginal samples (682) were collected by a tampon method from 50 healthy young women. Samples were analyzed by gas chromatography. The volatile aliphatic acids increased during the late follicular phase of the menstrual cycle and declined progressively during the luteal phase.

Pseudo catalytic transformation of volatile fatty acids into fatty acid methyl esters

Bioresource Technology, 2016
Instead of anaerobic digestion of biodegradable wastes for producing methane, this work introduced the transformation of acidogenesis products (VFAs) into fatty acid methyl esters (FAMEs) to validate the feasible production of short-chained fatty alcohols via hydrogenation of FAMEs.

Simplified automated volatile fatty acids analysis

Water Research, 1968
Abstract A method is proposed for the automated determination of the total volatile fatty acid content of aqueous samples. The manifold is simpler and the method quicker than existing procedures. No special preparation of the reagents is required. Improved accuracy results by taking into consideration the colour contributed by the sample itself.

Volatile Cuprous and Silver Salts of Fatty Acids

Nature, 1948
IN a communication in Nature1, one of us (F. K.) reported on a volatile copper compound obtained by thermal decomposition of cupriformate. J. G. Maltby2 directed attention to the work of A. Angel and A. V. Harcourt3, according to whom cuprous acetate forms as a white sublimate when cupriacetate is heated.

Volatile fatty acids, “copulins”, in human vaginal secretions

Psychoneuroendocrinology, 1975
Abstract (1) In a double-blind study using a new tampon method, 682 samples of vaginal secretions were collected from 50 healthy young women attending a university. (2) Samples were analyzed by gas chromatography for the volatile fatty acids (C2-C6) that have sex-attractant properties in infra-human primates.
