The rhodinol content is an essential component in determining the citronella oil qualities. This study aimed to develop a model calibrated predict using near-infrared (NIR) spectroscopy. research initial stage developing spectral smart sensor system that predicts of distillation and fractionating process. Citronella samples were scanned by NIRFlex liquid N-500 with wavelength 1 000–2 500 nm hav...

This study aims to observe customer's responses toward car fragrance products, examine the volatility and properness of essential oil-based product. Essential oil is a group vegetable in form liquid that easily evaporated at room temperature. Hence it gives unique scents. research carried out with descriptive method using qualitative approach. The data analysis technique this SWOT (Strength, We...

The essential oil extracted from Piper betle L. leaf using pilot plant steam distillation was tested against the adult housefly, Musca domestica, for insecticidal activity. LC50 values at the end of 24 and 48 h exposure periods were 10.3 and 8.7 mg/dm, respectively. Ceylon citronella oil (Cymbopogon nardus) used as a standard showed LC50s of 26.5 and 24.2 mg/dm for the same exposure periods. Bi...

Laboratory tests of commercial repellent formulations were conducted against Anopheles farauti Laveran, Culex annulirostris Skuse, Ochlerotatus vigilax (Skuse) and Stegomyia aegypti (L.). The majority of repellent formulations tested contain N,N,-diethyl-3-methylbenzamide (also known as diethyl-m-toluamide, commonly called deet). Two formulations containing picaridin (1-piperidinecarboxylate ac...

One of the problems that reduce a person's confidence is pediculosis. Natural ingredients used as anti-lice are citronella oil (Citronella oil), contains citronellal compounds. This study aims to obtain shampoo preparation has anti-head lice activity. Citronella formulated in several concentrations, namely 5% (FI), 7.5% (FII) and 10% (FIII). Evaluation preparations included organoleptic examina...

BACKGROUND & OBJECTIVES Many essential oils have been reported as natural sources of insect repellents; however, due to high volatility, they present low repellent effect. Formulation technique by using microencapsulation enables to control the volatility of essential oil and thereby extends the duration of repellency. In this study, the effectiveness of microencapsulated essential oils of Alpi...
