Tocophersolan (Vedrop, tocofersolan) or d-alpha-Tocopheryl Polyethylene Glycol 1000 Succinate (TPGS) is a watersoluble derivative of the natural active (d-alpha) isomer of vitamin E. The active constituent of the medicinal product is essentially vitamin E (alpha tocopherol). Chronic congenital or hereditary cholestasis is a clinical condition where vitamin E deficiency results from an impaired bile secretion. Decreased intestinal absorption observed in chronic congenital or hereditary cholestatic patients is due to decreased bile secretion and the resulting decrease in intestinal cellular absorption. As a result, fatsoluble vitamins (i.e. vit. E) are not absorbed properly and deficiency can occur. Tocophersolan (Vedrop) is used to treat or prevent vitamin E deficiency (low vitamin E levels). It is used in children up to the age of 18 years who have congenital or hereditary chronic cholestasis and who cannot absorb vitamin E from the gut. Tocophersolan (Tocofersolan) can be absorbed from the gut in children who have difficulty absorbing fats and vitamin E from the diet. This can increase vitamin E levels in the blood and help to prevent neurological deterioration (problems in the nervous system) due to vitamin E deficiency. No treatment-related findings were reported, as all clinical observations and findings at autopsy were similar in treatment and control groups. In many of the studies, the LD50 was not determined as tocofersolan was well tolerated.

Propyl Gallate is the n-propyl ester of gallic acid (3,4,5-trihydroxybenzoic acid). It is soluble in ethanol, ethyl ether, oil, lard, and aqueous solutions of polyethylene glycol (PEG) ethers of cetyl alcohol, but only slightly soluble in water. Propyl Gallate currently is used as an antioxidant in a reported 167 cosmetic products at maximum concentrations of 0.1%. Propyl Gallate is a generally recognized as safe (GRAS) antioxidant to protect fats, oils, and fat-containing food from rancidity that results from the formation of peroxides. The biological activity of Propyl Gallate is consistent with its free-radical scavenging ability, with effects that include antimicrobial activity, enzyme inhibition, inhibition of biosynthetic processes, inhibition of the formation of nitrosamines, anesthesia, inhibition of neuromuscular response to chemicals, ionizing/ultraviolet (UV) radiation protection, chemoprotection, antimutagenesis, anticarcinogenesis and antitumorigenesis, antiteratogenesis, and anticariogenesis. Propyl gallate has being shown to be a hepatoprotector in vitro and in vivo.

Ethylparaben is produced naturally and found in several fruits and insects, where it acts as an antimicrobial agent. Ethylparaben is mainly used as antiseptics in cosmetics, food and medicine (E number E214). It is also can be used as feed preservatives and antiseptic for bacteria. Ethylparaben is readily absorbed from the gastrointestinal tract or through the skin. It is hydrolyzed to p-hydroxybenzoic acid and rapidly excreted in urine without accumulating in the body. Under the Federal Food, Drug, and Cosmetic Act (FD&C Act), cosmetic products and ingredients, other than color additives, do not need FDA approval before they go on the market. Broad concentration ranges reported in each product category in 1981 were < 0.1% and > 0.1% to 1%. Studies show the in vivo estrogenicity of MP and EP at human exposure levels, and indicate that populations exposed to large amounts of MP and EP may have a high burden of estrogenicity-related diseases.

A. W. Van Hoffman was the first to isolate sorbic acid from the berries of the mountain ash tree in the year 1859. The antimicrobial (preservative) properties of sorbic acid were recognized in the 1940's. In the late 1940's and 1950's it became commercially available. Sorbic acid and its potassium salt are now used in many countries in the production of sweet white wines. In the United States, BATF permits the use of sorbic acid and potassium sorbate to preserve wine. The maximum concentration of sorbic acid allowed in finished wine is 300 mg/L, (300 ppm). The antimicrobial action of sorbic acid is primarily against yeasts and molds. It's action against bacteria appears to be selective. The soluble sorbates are preferred when it is desired to use the preservative in liquid form, or when aqueous systems are to be preserved. Sodium sorbate in solid form is unstable and very rapidly undergoes oxidation on exposure to atmospheric oxygen. It is therefore not produced on the industrial scale. Aqueous solutions of sodium sorbate remain stable for some time. Calcium sorbate is used in the manufacture of fungistatic wrappers because it is highly stable to oxidation, but this use is very limited. Sorbic acid and sorbates can be directly added into the product. The products can be dipped or sprayed with aqueous solutions of sorbates. Dusting of food with dry sorbic acid is also possible but less recommended because sorbic acid irritates the skin and mucous membranes. Sorbic acid and particularly calcium sorbate can be used as active substances in fungistatic wrappers. A general survey of the numerous uses of sorbic acid in the food sector will be given. Some fields of application will be discussed that are either unimportant or not permitted in the U.K.

Calcium stearate is a carboxylate of calcium, classified as a calcium soap. Calcium stearate is a component of some lubricants, surfactants, as well as many foodstuffs. It is a white waxy powder. Calcium stearate is a waxy material with low solubility in water, unlike traditional sodium and potassium soaps. Calcium stearate is also easy and cheap to produce and exhibits low toxicity. These attributes are the basis of many of its applications.

Neotame is a derivative of a dipeptide compound of the amino acids - aspartic acid and phenylalanine. Neotame has been developed as a sweetener with a high degree of sweetness and is obtained by N-alkylating aspartame. Its degree of sweetness varies according to the kind of food and blend composition. It is 7000 to 13,000 times and about 30 to 60 times sweeter than sugar and aspartame respectively. Neotame is rapidly metabolized, completely eliminated and does not accumulate in the body. The major metabolic pathway of neotame is hydrolysis of the methyl ester by esterase which is present throughout the body. This yields de-esterified neotame, the major metabolite and a significant amount of methanol. Due to the presence of the 3-3-di-methylbutyl group, peptidases which would typically break the peptide bond between the aspartic acid and phenylalanine moieties are essentially blocked, thus reducing the availability of phenylalanine. Neotame was approved by the USFDA as a general purpose sweetener in July 2002

Malic acid is a tart-tasting organic dicarboxylic acid that contributes to the taste of many sour or tart foods such as apples. Sodium Malate is the sodium salt of Malic Acid. Malic Acid and Sodium Malate can be found in a wide range of cosmetics and personal care products. Sodium Malate functions as a skin conditioning agent-humectant. As a food additive, Sodium Malate has the E number E350. Sodium Malate has demonstrated protective effect on cisplatin-induced toxicity in mice. Sodium malate could become a useful agent for the reduction of CDDP-induced toxicity, particularly nephrotoxicity and hepatotoxicity.

Calcium ferrocyanide is used as anti-caking agent. Known as E-538 food additive. Calcium ferrocyanide, because of the strong chemical bond between iron and the cyanide groups, theses salts have a low toxicity. Sodium ferrocyanide (E 535), potassium ferrocyanide (E 536) and calcium ferrocyanide (E 538) are permitted in salt and its substitutes at the level of 20 mg/kg (calculated as anhydrous potassium ferrocyanide) individually or in combination.
