Introduction Vegetable oils are liquid vegetable fats that remain in the liquid form at room temperature. These lipids are most commonly extracted from various parts of plants such as seeds, fruits, or plant seedlings. Under the chemical terms they are a combination of triglycerides of higher saturated and unsaturated fatty acids. In other words, these compounds are esters of glycerol and highe...

BACKGROUND Topical application of oils and oil-based formulations is common practice in skin care for both adults and infants. Only limited knowledge however is available regarding skin penetration and occlusive potential of oils and common methods for measuring skin moisturization fall short when it comes to the moisturizing effect of oils. OBJECTIVE In this study we used in vivo confocal Ra...

Triacylglycerols from plants, familiar to most people as vegetable oils, supply 25% of dietary calories to the developed world and are increasingly a source for renewable biomaterials and fuels. Demand for vegetable oils will double by 2030, which can be met only by increased oil production. Triacylglycerol synthesis is accomplished through the coordinate action of multiple pathways in multiple...

in order to compare the impact of vegetable oils to improve the efficacy of mesosulfuron-methyl + iodososulfuron - methyl + mefenpyr (atlantis)®, a greenhouse experiment of dose-response as factorial experiment in a completely randomized design including concentration 0, 3/75, 7/5, 15, 22/5, and second factor 30 g a.i. ha-1 of atlantis at 13 levels of with and without vegetable oils (each of tw...

Using urban household-level survey data from 1992 to 1998, we provide estimates of final demand for edible vegetable oils and animal fats in three regions of China based on the LinQuad incomplete demand system. For each region, the demand for the major “staple” oil is price inelastic. The demand for “condiment” or flavoring oils is more price responsive. All edible oils and fats have positive i...

In this study, three different vegetable-based cutting fluids developed from raw and refined sunflower oil and two commercial types (vegetable and mineral based cutting oils), were carried out to determine for thrust force and surface roughness during drilling of AISI 304 austenitic stainless steel with HSSE tool. The uses of vegetable cutting oils was investigated in reducing thrust force and ...

Vegetable oils present important pharmacological properties, which gained ground in the pharmaceutical field. Its encapsulation in nanoemulsions is considered a promising strategy to facilitate the applicability of these natural compounds and to potentiate the actions. These formulations offer several advantages for topical and systemic delivery of cosmetic and pharmaceutical agents including c...

This work describes the tribochemical evaluation of vegetable oil based antiwear additive obtained through chemical modification. The Sulfur was incorporated using a chemical reaction of epoxidized vegetable oil and common thiols, resulting in formation of a hydroxy thioether derivative of vegetable oils. The synthesis retains the vegetable oil structure, eliminates poly-unsaturation in the mol...

BACKGROUND The skin represents a potent barrier to the environment, which can be enhanced by the topical application of skin care products, such as oil and oil-based formulations by moisturizing the skin. METHODS The aim of this study was the investigation of the penetration behaviour of four vegetable oils and of paraffin oil into the stratum corneum by laser scanning microscopy. In addition...

Most fatty acids, vegetable oils and fatty esters, especially those with long carbon chains, do not have all pure component physical properties described in the literature, relevant for design and analysis of chemical processes. One way to obtain these properties is to use estimation methods such as group contribution methods which need only the structural information of the molecule. In this s...
