Arbutin, the beta-D-glucopyranoside of hydroquinone, is a skin whitening cosmetic ingredient. Compared with hydroquinone, arbutin is a less potent skin hyperpigmentation agent, but less toxic. Arbutin is found in a number of edible berry-producing plants such as blueberry and cranberry, marjoram, and most pear species. Chinchircoma (Muticia acuminatai) that contains arbutin, has been traditionally used by South American populations internally the fresh juice is used for gastric ulcers and internal tumors; the water of boiled leaves and flowers for illness of the respiratory tract; for hearth disorders or pain. According to pharmacological results in vitro, liver protective effects as well as anti-inflammatory activity were proven. It can also be beneficial for asthma and other anaphylactic reactions. This plant is component of the lsula Rain’s botanical products (Peru): ‘I-Day Digestive Cleanse #2.Herbal Supplement approved by FDA. As a hyperpigmentation agent arbutin inhibits tyrosinase and thus prevents the formation of melanin.

Butylated hydroxytoluene, commonly known as BHT, is an organic compound that is used in the food, cosmetic, and pharmaceutical industry as an antioxidant. BHT is a substituted derivative of phenol. BHT helps to prevent the formation of free radicals and oxidation. When used in food products, it delays oxidative rancidity of fats and oils, and prevents loss of activity of oil-soluble vitamins. It may be found in pharmaceutical gels, creams and liquid or gelatin capsules, tablets and other pharmaceutical dosage forms. The ability of oral BHT to lead to cancer is a controversial topic, but most food industries have replaced it with butylated hydroxyanisole (BHA). BHT was first used as an antioxidant food additive in 1954. BHT does have other commercial uses, as in animal feeds and in the manufacture of synthetic rubber and plastics, where it also acts as an antioxidant. The U.S. Food and Drug Administration has deemed that BHT is safe enough when used in limited concentrations. It currently permits its use in concentrations of about 0.01% to 0.02% in most foods. As an emulsion stabilizer in shortening, it may be used in a somewhat higher concentration, 200 parts per million.

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.

Hydroquinine (Inhibin®) has been approved for marketing in the Netherlands for the treatment of nocturnal cramps when treatment with drugs is considered necessary. It is available in the Netherlands since March 1990 as an over-the-counter drug with a dose of 200 mg with the evening meal and a further 100 mg at bedtime for 14 days. Hydroquinine also has antimalarial and demelanizing activity. It might be used to lightens light brown color patches on skin, age spots, skin discolorations associated with pregnancy, skin trauma or taking birth control pills. Hydroquinine is used in skin lightening creams and lotions because it is an effective bleaching agent, slowing the production of the tyrosinase enzyme and reducing the amount of melanin formed.
