Vegetable oils cosmetics applications

Based on these considerations, it appears that the best calculation approach for the prediction of the solubility of fullerenes in free fatty acids and in fatty acids derivatives is granted by equation (13.18), but simply because we are reasoning a posteriori. It is evident from our calculations that the surprising solubility of fullerenes in free fatty acids and glyceryl esters of fatty acids, or which is the same in vegetable oils, was not easily predictable and expected on the basis of theoretical considerations. Only the intuition of Braun et al. (2007) (see also Cataldo and Braun, 2007) has led to this important discovery, which may have implications and applications in medicine, cosmetics and possibly also in other fields. 

Highly concentrated emulsions are also evident in everyday applications. A classic example is mayonnaise, in which a large volume of vegetable oil is emulsified in a small amount of vinegar, using lecithin from egg-yolk as the emulsifier. In addition, HIPEs are most probably found in many cosmetic products, especially gels and creams. However, little information is available on products of commercial importance, so one can only speculate on their exact nature and composition. 

Sorbitan oleate and the monolaurate are pale yellow liquids. Palmitates and stearates are light tan solids. Sorbitan esters are not soluble in water but dissolve in a wide range of mineral and vegetable oils. They are lipophilic emulsifiers, solubilizers, softeners, and fiber lubricants that find application in synthetic fiber manufacture, textile processing, and cosmetic products. Sorbitan esters have been approved for human ingestion and are widely used as emulsifiers and solubilizers in foods, beverages, and pharmaceuticals. 

A wide range of vegetable and animal oils and fats are currently being used as bases and bioactive ingredients in many cosmetic applications. Typical applications of lipids in cosmetics include emollients and specific ingredients for skin care and treatment, hair care, and make-up/decorative products. The type of lipids commonly used in cosmetics include TAGs, emulsifiers, waxes, and structured lipids. The cosmetics industry was more than 25 billion in 2000, and new products are continually introduced in the market. 

Solvent extraction is used extensively to recover chemicals from natural products. Solvents are used to extract and concentrate natural oils and products in the bioprocessing industries (nutraceu-tical, food, pharmaceutical, feed, cosmetic, biotechnology) in quantities from grams to metric tons. Biotechnology applications include the recovery of primary and secondary metabolites [4]. Extraction is used to recover vegetable oils and food products. It is used to process a variety of materials including groundnut, mustard seed, soybean, pahn kemal, sunflower, rice bran, copra, cottonseed, and minor oil seeds like neem, mahua, watermelon seed, castor seed, and so on. 

Oleic acid is a monounsaturated fatly acid found in high concentrations in vegetable oils, presenting a broad number of applications in many industrial areas, such as food, pharmaceutical, cosmetic, oleochemical and biodiesel industries. Due to the lipophilicity, unsaturation and acidic characteristics that this compound presents, oleic acid can be effectively ttsed in esterification and acidolysis, among other reactions. Recent studies have used oleic acid as an efficient substrate for synthesis of trimethylolpropane esters by esterification using lipase from Candida Antarctica, since this polyol ester is widely applied in hydraulic... 

Some processes are already applied in commercial industrial production plants, but others are still in need of development to reach commercialization. The production of vegetable oils for food has been a commercial process since a long time ago. The same is true for the traditional use of fatty acid esters in cosmetics and detergents. However, the microbial production of fatty acids (natural and unnatural) is stiU in its infancy. New applications for vegetable triglyceride oils and crude tall oil (CTO) are also at a laboratory... 

Animal and Vegetable Oils. Animal and vegetable oils, as the terms indicate, are oils derived from those sources. They can be used where food contact is likely to occur and the lubricant must be edible. Their main disadvantage is that most of them tend to deteriorate rapidly in the presence of heat. Petroleum oils, on the other hand, can be refined to such a degree that all undesirable components can be removed and thus be labeled USP or white oil, suitable for medicinal, cosmetic, or incidental food-contact applications.
