cream
Bleach cream is a mixture of bleach and other chemicals with properties could memucatkan black stain (brown) on the skin. Purpose of its use in a long time in order to eliminate or reduce hyperpigmentation of the skin, but should continue to use it will cause permanent pigmentation of the effect.
a. The active ingredient of bleach cream.
The active ingredient in most modern bleaching preparations are the salt of mercury, the most commonly used materials of this type kloroamida mercury (mercury amide chloride, HgNH2Cl2), mercury chloride (sublimate, HgCl2), merkurous chloride (calomel, Hg2Cl2). All these compounds except Hg2Cl2 are not soluble in water, fat and organic solvent and mixed into the cream in the form of fine dispersion.
b. How a whitening cream
Effects of mercury salts depending on inhibasi tirikinaase enzyme responsible for the first stage of oxidation of tyrosine into melanin, so the early stages of a chain reaction that led to the formation of melanin does not occur and brightened skin or white.
Melanin that there can not be destroyed but prevented the formation of pigment. Additional Seabagai, sublimat have exfoliating effect because melepaskab HCl at the very top layer of skin that attack corneum.
B. Mercury (quicksilver)
a. The characteristics of mercury
Of mercury (hg) the atomic-number 80, atomic weight 200.59 + 0.03, it is a symbol of Hg derived from Greek or Latin Hydrargyros hydrargyrum, "silver water" or "liquid silver". is the third and last member, or group IIB (related) periodic system, the other is the cadmium and zinc. although cadmium and zinc showed many similarities and are often discussed together, but the mercury mercury differ in various aspects of the behavior and its wealth, but still on the class itself.
Mercury is a metal that exists naturally, the only metal liquid at room temperature. The pure metal silvery, odorless liquid, shiny,. When the temperature of 357 oC dipaanaskan mercury will mengauap.
Mercury is often also called mercury, can be in various compounds. When joined with chlorine, sulfur or oxygen, mercury will form a salt which is usually a white solid tangible
Quicksilver (mercury) are known, because; since antiquity Aristotle mentions its use in religious ceremonies; Almaden mine dinegaraSpaindan that described by Theophrastus. is the beginning of its use in connection with the preparation of drugs; its use in the treatment of syphilis has dierkenalkan by Paracelsus in the sixteenth century.
Sperm cells of mercury used in radio equipment, hearing aids, missiles, and many other uses: in a Geiger-Mueller counter, their development in late-1940 eventually led to a significant increase in the consumption of mercury.
Studies on the toxicity of mercury is the most mainstream analysts: metal and most of the volatile mixture of lead, mercury can be absorbed through the skin even
Metallic mercury is a toxicant that unique group. These metals can be found and settled dialam, but its chemical form may change due to the influence fisiokima, biological or due to human activities. Tosksitas may change drastically when changing their chemical form of metals generally bermamfaat for humans because of its use in industrial, agriculture or medicine.
The main work of this metal inhibits the enzyme, these effects usually arise from the interaction between the metal with the enzyme's SH groups. An enzyme can also be inhibited by toxic metals through the eviction essential cofactor of the enzyme.
b. Sources of mercury
as the element mercury (Hg) is a liquid. The metal is removed from the earth's crust through pendegasan. Mercury is also present in the environment as inorganic and organic compounds.
C. Negative Effects of Mercury Metals
1. when ingested, these substances will cause stomach cramps and bloody diarrhea with corrosive ulceration, hemorrhage and necrosis in the gastrointestinal tract and kidney damage.
2. use of mercury makes the skin smooth, but then settle under the skin. after years of blue-black would be even lead to cancer.
