Mouthwash is a liquid, aqueous composition that primarily used to treat oral conditions, as well maintain health. The purpose of this study was prove the antibacterial efficacy citronella essential oil against Streptococcus mutans bacteria made in mouthwash formulations. Citronella analyzed using GC-MS and then formulated into with concentrations 1.5%, 3% 4.5% at cold temperatures (2-8°C) room ...

Plant essential oils are widely used as fragrances and flavours in the cosmetic, perfume, drug and food industries. Oxygenated monoterpenes are widespread components of the essential oils, usually occurring in high amount. In this paper, the antibacterial activities of twenty-one oxygenated monoterpenes (borneol, borneol acetate, camphor, carvone, 1,8-cineole, citronellal, beta-citronellol, dih...

We tested the ability of human subjects to distinguish between enantiomers, i.e. odorants which are identical except for chirality. In a forced-choice triangular test procedure 20 subjects were repeatedly presented with 10 enantiomeric odor pairs and asked to identify the bottle containing the odd stimulus. We found (i) that as a group, the subjects were only able to significantly discriminate ...

With use of a conditioning paradigm, the ability of six squirrel monkeys to distinguish between 10 pairs of enantiomers, i.e., odorants that are identical except for chirality, was investigated. As a group, the animals were only able to discriminate between the optical isomers of α-pinene, carvone, limonene, and fenchone, whereas they failed to distinguish between the (+) and (-) forms of β-cit...

A valid quantitative method for the analysis of chiral monoterpenes in white wine using head-space solid phase micro-extraction-MDGC-MS (HS-SPME-MDGC-MS) with stable isotope dilution analysis was established. Fifteen compounds: (S)-(-)-limonene, (R)-(+)-limonene, (+)-(2R,4S)-cis-rose oxide, (-)-(2S,4R)-cis-rose oxide, (-)-(2R,4R)-trans-rose oxide, (+)-(2S,4S)-cis-rose oxide, furanoid (+)-trans-...

Case Report A 50-year-old woman developed a pruritic rash on her hands and forearms, spreading to the trunkwhile sparing the upper arms, after applying an ointment (Totes Meer Pflegebalsam®) and a skin aerosol (Panthenol Spray®) to treat irritant hand eczema caused by intensive gardening. Patch tests with the original products and several test series of the German Contact Dermatitis Research Gr...

Clove buds and lemongrass leaves were collected from three different locations of India and the essential oil was separated by hydrodistillation procedure. The essential oils were studied for its variation in physical properties and chemical composition. Chemical analysis by GC-MS evidenced that the main components of clove oil (CLV) were eugenol (78.5-87.7%) and caryophyllene (12.3-20.2%) and ...

Background Since the available anti-inflammatory drugs exert an extensive variety of side effects, the search for new anti-inflammatory agents has been a priority of pharmaceutical industries. Aims The aim of the present study was to assess the anti-inflammatory activities of the essential oil of rose geranium (RGEO). Methods The chemical composition of the RGEO was investigated by gas chromato...

BACKGROUND The fragrance mix (FM I), established in 1977, detects the majority, but not all cases of contact allergy to fragrances. Based on European research 2002/2003, fragrance mix II (FM II) was developed to supplement FM I. In 2005, the German Contact Dermatitis Research Group (DKG) added FM II to their baseline series. OBJECTIVES To evaluate reactions to FM II and its constituents in ro...

The genus Cymbopogon (Poaceae) is most important from the point of view of their essential oils. Essential oils from these species are widely used in flavours, fragrances, cosmetics, soaps, detergents and perfumery owing to their typical lemon and rose-like aroma. Cymbopogon essential oils and constituents present therein e.g. citral, geraniol, citronellol, citronellal and piperitone, have been...
