Ethyl acetate is a widely used synthetic solvent. It is used in cosmetics and considered to be safe. Ethyl acetate is cited as a direct and indirect food additive as detailed in the Code of Federal Regulations. Ethyl acetate is generally recognized as safe (GRAS) for use as a synthetic flavor and/or adjuvant; limitations on concentrations of use were not specified. Ethyl acetate was tested for in vitro in human breast cancer cell line and demonstrated considerable cytotoxicity.

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.

D&C Green No. 5 is an FDA-approved, synthetic dye produced from petroleum or coal tar sources, that used in pharmaceuticals and cosmetics. D&C Green No. 5 may be safely used for coloring drugs and surgical sutures. In cosmetics, it can be used externally and in general cosmetics, including lipsticks, and cosmetics close to the eye.

Ethoxyquin (EQ) has been used as an antioxidant in animal feed for many years, but pharmacological use of EQ has never been evaluated in humans despite that small amounts of EQ exist in certain food items. The level of this antioxidant in animal feeds should not be higher than 150 ppm (U.S. FDA permissions). Ethoxyquin is rapidly absorbed from gastrointestinal tract of laboratory animals like rats and mice. Peak blood concentration of the compound is observed within 1 h. Distribution of EQ in animal body is similar when it is administered orally and intravenously. Small amounts of parent EQ were detected in liver, kidney, and adipose tissue and fish muscles. It is excreted predominantly as metabolites via urine. Ethoxyquin is also registered as an antioxidant to control scald (browning) in apples and pears. EQ-induced DNA damage in human lymphocytes in a dose-dependent manner. According to the studies on dogs and laboratory animals it was shown that ethoxyquin had little acute toxicity, except when it is administered parenterally. Values of LD50 for EQ are 1700 mg kg−1 bw (rats, oral gavage), 2000 mg kg−1 bw (rats, dermal treatment, 24 h), 900 mg kg−1 bw (mice, intraperitoneal administration), and 180 mg kg−1 bw (mice, intravenous administration).

Biebrich scarlet red (scarlet red) an azo dye that has been used to impart color to pharmaceutic preparations. The color produced by the longest waves of the visible spectrum, approximately 630 to 750 nm. In combination with phenol it’s used in veterinary to treat Superficial Wounds, Cuts, Lacerations, Slow Healing Ulcers, Abrasions, Burns, Chafes.

Colchiceine, a metabolite of colchicine, commonly used to treat gout, was studied as an effective compound in the model of liver damage.

D&C RED NO. 40 is an inactive component (color additive) of RYCLORA®, an antihistamine agent with anticholinergic (drying) and sedative side effects, which is effective for the symptomatic relief of perennial and seasonal allergic rhinitis, vasomotor rhinitis, allergic conjunctivitis due to inhalant allergens and foods, mild and uncomplicated allergic skin manifestations of urticaria and angioedema, dermographism, amelioration of allergic reactions to blood or plasma.
