BACKGROUND & OBJECTIVES Repellents are commonly used personal protection measures to avoid mosquito bites. In the present study, Advanced Odomos cream (12% N, N-diethyl-benzamide) was tested for its efficacy against mosquitoes in comparison to DEET (N,N-diethyl-3-methyl benzamide). METHODS Bioassays were conducted to assess the repellency of Advanced Odomos and DEET creams against Anopheles s...

Abstract Poly(butylene succinate) (PBS) is used to produce micro-/nanoporous biodegradable scaffolds, suitable for the release of mosquito repellent N , -diethyl-3-methylbenzamide (DEET), based on thermally induced phase separation. For solvent-rich compositions up 30 m% PBS, it was found that PBS dissolves in DEET at elevated temperatures. During cooling, spherulitic crystallization occurs, wi...

Oxidative scrubbing is used to remove H2S from gas streams. A key problem in regeneration of the absorbent is the removal of fine particles of sulphur from the suspension of the scrubbing liquid. Dispersions of ultra-fine bubbles have been called "colloidal gas aphrons" or aphrons for short. These dispersions have interesting properties and it was found that they have particular advantages in t...

In this work attempts were made to evaluate K+-SDS and hydrocolloid polymer-SDS interactions in flocculation of megestrol acetate dispersions to enhancetheir stability as a part of suspension formulation. Different dispersions of micronized megestrol acetate and SDS were prepared. KCl and KH2PO4 and their corresponding sodium salts were added to the dispersions and the preparations were evaluat...

D EET ([N-N]-diethyl-mtoluamide) is widely used around the world as a repellent for mosquitoes and other biting insects. It was originally identified by a structure–activity study using synthetic compounds (1). Recently, a number of new compounds with similar activity [e.g., picaridine (2)] have been identified, but DEET remains the gold standard. Despite a tremendous number of studies (3), how...

Two new field bioassay methods were developed to compare the repellent activity of BioUD(®) (containing 7.75% 2-undecanone), 98.1% DEET and 0.5% permethrin against natural populations of nymphal Amblyomma americanum (L.) (Acari: Ixodidae). In a cloth sheet assay, pieces of material measuring 41 × 58 cm, separately treated with one of the test materials or the appropriate solvent carrier, were p...

Objective: The purpose of this research is to prepare a cinnamon bark essential oil gel preparation, determines the physical characteristic and stability during storage, examines activity mosquito repellent from best preparation. Methods: formulations were made with variations in concentration Carbopol 940 (0.5%, 1.5%, 2%) contain 1% oil. evaluated characteristics stability. parameters organole...
