Chemical Depilatory
A chemical depilatory is a Cosmetics, cosmetic preparation used to Hair removal, remove hair from the skin. Common active ingredients are salts of thioglycolic acid and thiolactic acids. These compounds break the disulfide bonds in keratin and also hydrolyze the hair so that it is easily removed. Formerly, sulfides such as strontium sulfide were used, but due to their unpleasant odor, they have been replaced by thiols. The main chemical reaction affected by the thioglycolate is: : Chemical depilatories contain 5–6% calcium thioglycolate in a Cream (pharmaceutical), cream base (to avoid runoff). Calcium, Calcium hydroxide or strontium hydroxide maintain a pH of about 12. Hair destruction requires about 10 minutes. Depilation is followed by careful rinsing with water, and various conditioners are applied to restore the skin's pH to normal. Depilation does not destroy the dermal papilla, and the hair grows back. Chemical depilatories are available in gel, Cream (pharmaceutical) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cosmetics
Cosmetics are substances that are intended for application to the body for cleansing, beautifying, promoting attractiveness, or altering appearance. They are mixtures of chemical compounds derived from either Natural product, natural sources or created synthetically. Cosmetics have various purposes, including personal care, personal and skin care. They can also be used to conceal blemishes and enhance natural features (such as the eyebrows and eyelashes).

Strontium Hydroxide
Strontium hydroxide, Sr(OH)2, is a caustic alkali composed of one strontium ion and two hydroxide ions. It is synthesized by combining a strontium Salt (chemistry), salt with a strong base. Sr(OH)2 exists in anhydrous, hydrate, monohydrate, or octahydrate form. Preparation Because Sr(OH)2 is slightly soluble in cold water, its preparation can be easily carried out by the addition of a strong base such as Sodium hydroxide, NaOH or Potassium hydroxide, KOH, drop by drop to a solution of any soluble strontium salt, most commonly Sr(NO3)2 (strontium nitrate). The Sr(OH)2 will precipitate out as a fine white powder. From here, the solution is filtered, and the Sr(OH)2 is washed with cold water and dried. Applications Strontium hydroxide is used chiefly in the refining of beet sugar and as a stabilizer in plastic. It may be used as a source of strontium ions when the chlorine from strontium chloride is undesirable. Strontium hydroxide absorbs carbon dioxide from the air to form stron ...

Arsenic Trisulfide
Arsenic trisulfide is the inorganic compound with the formula . It is a dark yellow solid that is insoluble in water. It also occurs as the mineral orpiment (Latin: auripigmentum), which has been used as a pigment called King's yellow. It is produced in the analysis of arsenic compounds. It is a group V/VI, intrinsic p-type semiconductor and exhibits photo-induced phase-change properties. Structure occurs both in crystalline and amorphous forms. Both forms feature polymeric structures consisting of trigonal pyramidal As(III) centres linked by sulfide centres. The sulfide centres are two-fold coordinated to two arsenic atoms. In the crystalline form, the compound adopts a ruffled sheet structure. The bonding between the sheets consists of van der Waals forces. The crystalline form is usually found in geological samples. Amorphous does not possess a layered structure but is more highly cross-linked. Like other glasses, there is no medium or long-range order, but the first co-ordi ...

Orpiment
Orpiment, also known as ″yellow arsenic blende″ is a deep-colored, orange-yellow arsenic sulfide mineral with formula . It is found in volcanic fumaroles, low-temperature hydrothermal veins, and hot springs and may be formed through sublimation (phase transition), sublimation. Orpiment takes its name from the Latin ''auripigmentum'' (''aurum'', "gold" + ''pigmentum'', "pigment"), due to its deep-yellow color. Orpiment once was widely used in artworks, medicine, and other applications. Because of its toxicity and instability, its usage has declined. Etymology The Latin ''auripigmentum'' (''aurum'', "gold" + ''pigmentum'', "pigment") referred both to its deep-yellow color and to the historical belief that it was thought to contain gold. The Latin term was used by Pliny the Elder, Pliny in the first century CE. The Greek for orpiment was ''arsenikon'', deriving from the Greek word ''arsenikos'', meaning "male", from the belief that metals were of different sexes. This Greek te ...

King Solomon
King is a royal title given to a male monarch. A king is an absolute monarch if he holds unrestricted governmental power or exercises full sovereignty over a nation. Conversely, he is a constitutional monarch if his power is restrained by fixed laws. Kings are hereditary monarchs when they inherit power by birthright and elective monarchs when chosen to ascend the throne. *In the context of prehistory, antiquity and contemporary indigenous peoples, the title may refer to tribal kingship. Germanic kingship is cognate with Indo-European traditions of tribal rulership (cf. Indic ''rājan'', Gothic ''reiks'', and Old Irish '' rí'', etc.). *In the context of classical antiquity, king may translate in Latin as '' rex'' and in Greek as ''archon'' or ''basileus''. *In classical European feudalism, the title of ''king'' as the ruler of a ''kingdom'' is understood to be the highest rank in the feudal order, potentially subject, at least nominally, only to an emperor (harking back ...

Polycystic Ovary Syndrome
Polycystic ovary syndrome, or polycystic ovarian syndrome, (PCOS) is the most common endocrine disorder in women of reproductive age. The name is a misnomer, as not all women with this condition develop cysts on their ovaries. The name originated from the observation of cysts which form on the ovaries of some women with this condition. However, this is not a universal symptom and is not the underlying cause of the disorder. The primary characteristics of PCOS include hyperandrogenism, anovulation, insulin resistance, and neuroendocrinology, neuroendocrine disruption. Women may also experience Abnormal uterine bleeding, irregular menstrual periods, Menorrhagia, heavy periods, hirsutism, excess hair, acne, pelvic pain, infertility, difficulty getting pregnant, and patches of acanthosis nigricans, darker skin. Beyond its reproductive implications, PCOS is increasingly recognized as a multifactorial metabolic condition with significant long-term health consequences, including an ...

Hirsutism
Hirsutism is excessive body hair on parts of the body where hair is normally absent or minimal. The word is from early 17th century: from Latin ''hirsutus'' meaning "hairy". It usually refers to a male pattern of hair growth in a female that may be a sign of a more serious medical condition, especially if it develops well after puberty. Cultural stigma against hirsutism can cause much psychological distress and social difficulty. Discrimination based on facial hirsutism often leads to the avoidance of social situations and to symptoms of anxiety and depression. Hirsutism is usually the result of an underlying endocrine imbalance, which may be adrenal, ovarian, or central. It can be caused by increased levels of androgen hormones. The amount and location of the hair is measured by a Ferriman–Gallwey score. It is different from hypertrichosis, which is excessive hair growth anywhere on the body. Treatments may include certain birth control pills, antiandrogens, or ins ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Veet
Veet, formerly called Neet and Immac, is a Canadian brand of chemical depilatory products manufactured by the British-Dutch company Reckitt Benckiser. Hair removal cream, lotions, gel, mousse, and wax products are produced under this brand, with differing variants being sold internationally. Previous products produced under the Neet and Immac brands were similar to those produced today. Veet's hair removal products contain thioglycolic acid and potassium hydroxide. These ingredients react to generate the depilatory chemical potassium thioglycolate, which according to the company, increases hair loss. The effect is to break the disulfide bonds of the keratin molecules in hair. This reduces the tensile strength of the keratin so greatly that the hair can be wiped away.

Powder (substance)
A powder is a dry solid composed of many very fine particles that may flow freely when shaken or tilted. Powders are a special sub-class of granular materials, although the terms ''powder'' and ''granular'' are sometimes used to distinguish separate classes of material. In particular, ''powders'' refer to those granular materials that have the finer grain sizes, and that therefore have a greater tendency to form clumps when flowing. ''Granulars'' refer to the coarser granular materials that do not tend to form clumps except when wet. Types Many manufactured goods come in powder form, such as flour, sugar, ground coffee, powdered milk, copy machine toner, gunpowder, cosmetic powders, and some pharmaceuticals. In nature, dust, fine sand and snow, volcanic ash, and the top layer of the lunar regolith are also examples. Because of their importance to industry, medicine and earth science, powders have been studied in great detail by chemical engineers, mechanical engineers ...
