Potassium sorbate is salt of sorbic acid and is prepared by reacting sorbic acid with potassium hydroxide. It is a white or yellowish crystalline powder or granule. Potassium sorbate is soluble in water. Once dissolved in water, it produces sorbic acid. It is effective as a preservative up to a pH of 6.5. Its effectiveness falls off as pH is lowered. It is inexpensive to produce, shelf stable and easy to use as an ingredient in foods and other products requiring antimicrobial activity.
Potassium sorbate(CAS NO:24634-61-5) is used as a preservative ingredient in many food products. It inhibits microbial growth, thereby reducing the risk of disease from and increasing the shelf life of food items. It can be used in a variety of foods including dairy products, baked goods, beverages, cured fish and meats, vegetable and fruit products, and confections.
In most cases, potassium sorbate is considered non-toxic and safe for use in commercial and culinary applications. However, some scientists believe that the addition of synthetic ingredients to foods, especially foods which are consumed quite regularly, can cause long term side effects which can be harmful.
Potassium sorbate is a skin, eye and respiratory irritant. Although some research implies it has a long term safety record, in vitro studies have shown that it is both genotoxic and mutagenic to human blood cells. Potassium sorbate is found to be toxic to human DNA in peripheral blood lymphocytes, and hence found that it negatively affects immunity. It is often used with ascorbic acid and iron salts as they increase its effectiveness but this tends to form mutagenic compounds that damage DNA molecules.
Intravenous feeding of potassium sorbate reduces gastric burden of pathogenic bacteria. It is often used with ascorbic acid and iron salts as they increase its effectiveness but this can form mutagenic compounds that damage DNA molecules.
Potassium sorbate has been generally recognized as safe for use in foods and personal care products.

What is 17-methyltestosterone?
17-methyltestosterone is a white to off-white crystalline powder, it is stable under normal temperatures and pressures, the Density is 112, Boiling Point is 104-116 C, Melting Point is 162-168 C, and Flash Point is 185.3 C. It has the Molecular Formula:C20H30O2, and Molecular Weight:302.451. The CAS Registry Number is 58-18-4.
17-methyltestosterone is a synthetic anabolic steroid used for treating men with testosterone deficiency or similar androgen replacement therapies. Also, has antineoplastic properties and so has been used secondarily in women with advanced breast cancer. In fish culture, used to produce monosex populations of those species which tend to overpopulate
17-methyltestosterone(CAS NO:58-18-4) is a steroid hormone from the androgen group. It is primarily secreted from the testes of males. In females, it is produced in the ovaries, adrenal glands and by conversion of adrostenedione in the periphery. It is the principal male sex hormone and an anabolic steroid.
In both males and females, it plays key roles in health and well-being. Examples include enhanced libido, energy, immune function, and protection against osteoporosis. On average, the adult male body produces about twenty times the amount of testosterone than an adult female's body does.
The effects of 17-methyltestosterone in humans and other vertebrates occur by way of two main mechanisms: by activation of the androgen receptor (directly or as DHT), and by conversion to estradiol and activation of certain estrogen receptors.
Free 17-methyltestosterone is transported into the cytoplasm of target tissue cells, where it can bind to the androgen receptor, or can be reduced to 5α-dihydrotestosterone (DHT) by the cytoplasmic enzyme 5α-reductase. DHT binds to the same androgen receptor even more strongly than T, so that its androgenic potency is about 2.5 times that of T.
The T-receptor or DHT-receptor complex undergoes a structural change that allows it to move into the cell nucleus and bind directly to specific nucleotide sequences of the chromosomal DNA. The areas of binding are called hormone response elements (HREs), and influence transcriptional activity of certain genes, producing the androgen effects.
The Side effects of 17-methyltestosterone include amnesia, anxiety, discolored hair, dizziness, dry skin, hirsutism, hostility, impaired urination, paresthesia, penis disorder, peripheral edema, sweating, and vasodilation.

What is Glyoxal?
Glyoxal is an organic compound with the formula C2H2O2. This white or off-white crystalline is the smallest dialdehyde (two aldehyde groups). Its tautomer acetylenediol is unstable. The Molecular Weight is 58.04, CAS Registry Number is 107-22-2.
Be careful to the Stability Combustible of Glyoxal. It is incompatible with strong oxidizing agents, strong reducing agent. It may polyermize exothermically, and it is incompatible with air, water, oxygen, peroxides, amides, amines, hydroxy-containing materials, nitric acid, aldehydes. Corrodes many metals.
Glyoxal(CAS NO: 107-22-2) practically does not exists as the well-known volatile dialdehyde, but in commercial 40% aqueous solutions, it is predominantly found in non-volatile hydrated and oligomeric forms. Glyoxal is an inflammatory compound formed when cooking oils and fats are heated to high temperatures. It is supplied typically as a 40% aqueous solution. Like other small aldehydes, glyoxal forms hydrates. Furthermore, the hydrates condense to give a series of oligomers, the structures of which remain uncertain. For most applications, the exact nature of the species in solution is inconsequential.
Glyoxal is used as starting material for the synthesis of crosslinking agents, in the textile finishing industry for instance to make urea Glyoxal formaldehyde resins. The paper industry uses large amounts of Glyoxal, where its cellulose crosslinking properties are appreciated to make paper suitable for offset printing and to improve its wet-strength. Through its methylic or ethylic monoacetals or acetals, it is also a key compound in a wide variety of chemistries and applications.
Coated paper and in the textile finishes use large amounts of glyoxal as a crosslinker for starch-based formulations and as a starting material with ureas for wrinkle-resistant chemical treatments. It is used as a solubilizer and cross-linking agent in polymer chemistry: proteins (leather tanning process),collagen,cellulose derivatives (textiles),hydrocolloids,starch (paper coatings)
It is a valuable building block in organic synthesis, especially in the synthesis of heterocycles such as imidazoles. A convenient form of the reagent for use in the laboratory is its bis-hemiacetal with ethylene glycol, 1,4-dioxane-2,3-diol. This compound is commercially available.
The first commercial Glyoxal source was in Lamotte, France, started in 1960 and currently owned by Clariant. The single largest commercial source is BASF in Ludwigshafen, Germany at ~60,000 tons/annum. Until recently only 2 production sites existed in the Americas, however the 45kMT Charlotte facility is closed. Significant capacity has been added recently in China. Commercial bulk Glyoxal is made and reported as a 40%-strength solution.
