Description and usage of Salicylic Acid:
Salicylic Acid is the raw material to produce medicine, perfume, dyestuff, pesticide and rubber cure retarder. Chiefly Salicylic Acid is used to manufacture the medicine of fever-allaying and analgesic for fever, direct dyestuff, insecticide and absorbent of ultraviolet ray.
As a professional China Clotrimazole Raw Material supplier and Manufacturer in China, FENGCHEN GROUP CO., LTD has been supplying and exporting Clotrimazole API from China in China for almost 10 years.
Salicylic acid powder Raw material, API is one of acne's biggest enemies. Salicylic acid belongs to a group of medicines known as keratolytics. It is used in the treatment of scaly skin diseases where the skin has become thickened, scaly and flaky. How exactly does salicylic acid work, and which type of acne is it best for?
Salicylic acid powder Raw material, API is a beta hydroxy acid. It is very useful especially great at attacking pimples.
The structure of salicylic acid a little complicated. It is the very structure which is the very reason why Salicylic acid works so well. The hydroxy part of salicylic acid is separated from the acid part by two carbon atoms, as opposed to an alpha hydroxy acid where they're separated by one carbon atom. This structure of Salicylic Acid is important because it makes it more oil soluble, making it possible to penetrate into the pores of the skin. In other words, Salicylic acid powder Raw material, API works by attacking the skin's "glue".
Once Salicylic acid has penetrated the skin, the acid part will dissolve some of the intercellular 'glue' which holds skin cells together. In contrast, alpha hydroxy acids end up just exfoliating the skin when they touch the surface. This is Salicylic acid powder Raw material, API’s advantage.
The chemical formula for salicyclic acid is C6H4(OH)CO2H.
Salicylic acid is both a caroxylic acid and a phenol. A carboxylic acid is an organic (carbon-containing) acid characterized by the presence of a carboxyl group, with the formula-C(=O)OH, usually written -COOH or -CO2H. A phenol, in the general sense of the term, is any compound which contains a six-membered aromatic ring, bonded directly to a hydroxyl group (-OH).
In salicylic acid, the OH group is adjacent to the carboxyl group.
Solubility: Salicylic acid is only slightly soluble in water, but is soluble in ethanol and ether.
Salicylic acid is commercially prepared from sodium salicylate, which is produced from sodium phenoxide and carbon dioxide at high pressure and temperature in the Kolbe-Schmitt reaction. Sodium salicylate is acidified to give the desired salicylic acid.
To produce aspirin, Salicylic acid powder Raw material, API is then acetylated using acetic anhydride, yielding aspirin and acetic acid as a byproduct. By using a process involving the esterification of the phenolic hydroxyl group of salicylic acid, it retains some of its potency as an analgesic while reducing its acidity.
One of the primary uses of salicylic acid is for the production of aspirin. Aspirin, or acetylsalicylic acid, is a drug often used as an analgesic (against minor pains and aches), antipyretic (against fever), and anti-inflammatory (against localized redness, swelling, heat, and pain). It has also an anticoagulant ("blood-thinning") effect and is used in long-term low-doses to prevent heart attacks.
Topical preparations of salicylic acid, either alone or in combination with other medicines, can be used to treat the following common scaly skin conditions:
-Chronic atopic dermatitis
Salicylic acid powder API Raw Material works by softening keratin, a protein that forms part of the skin structure. The above process helps to loosen dry scaly skin making it easier to remove. When used in conjunction with other drugs, salicylic acid takes off the upper layer of skin allowing the additional medicines to penetrate more effectively.
In acne, topical salicylic acid helps slow down shedding of the cells inside the follicles, preventing clogging. Salicylic acid also helps break down blackheads and whiteheads.
Description and usage of Methyl Salicylate
Methyl Salicylate is Colourless or light yellow oily liquid, with Melting Point-8.6℃,boiling point 223.6℃, relative density 1.1738, refractive index 1.5369. Methyl Salicylate is easily soluble in alcohol, acetic acid, soluble in ether, chloroform, slightly soluble in water.
Methyl Salicylate is the intermediates of medicine. Methyl Salicylate can be used as solvent and intermediate. Methyl Salicylate is widely used to manufacture insecticide, perfume, coating, cosmetics, printing ink, etc.
