salicylic acid

           salicylic acid, also known as salicylic acid, salicylic acid, and o-hydroxybenzoic acid, is a fat-soluble organic acid that is widely found in nature and was originally extracted from willow bark. It is also found in the leaves of white pearl, sweet birch, cohote roots, tulip flowers, hibiscus hibiscus, maple and rabdosia leaves, mulberry fruit, the roots of Yunnan white pearl and other plants. It is also found in fruits, vegetables, nuts, herbs, jams, honey, yeast extracts, tea, coffee, juice, beer and wine. It has the chemical properties of phenl and acid. The reaction of dilute aqueous solution with feric trichloride can produce purple yellow iron complex, which decomposes in strong acid. In case of heavy metal ions such as mercuy, lead and silver, they form water-insoluble salts; It reacts with bromie water to form white precipitate of tribromophenl. Aqueous solution shows acidic reaction, can be neutralized by alkali or carbonate alkali to form sodium salt and soluble in water; When heated above the melting point, carboxylic acid is removed to form phenl

Salicylic acid, is an organic acid, chemical formula for C7H6O3, a white crystalline powder, slightly soluble in cold water, soluble in hot water, ether and acetone, soluble in hot benzene, mainly used as an important raw material for pharmaceuticals, fragrances, dyes, pesticides, rubber additives and other fine chemicals.

Application

Medical field:
Antipyretic, analgesic, anti-rheumatic: salicylic acid has antipyretic, analgesic, anti-rheumatic effect, can be used to relieve fever, headache, joint pain, toothache, neuralgia and other symptoms caused by a variety of reasons. For example, the main component of aspirin tablets is salicylic acid derivative acetylsalicylic acid, which is widely used in clinical practice.
Treatment of skin diseases:
Keratolytic: Different concentrations of salicylic acid preparations have different effects in the treatment of skin diseases. 2%-6% salicylic acid ointment can be used to treat superficial fungal skin diseases; About 10% salicylic acid cream, often used to treat acne, seborrheic dermatitis; Salicylic acid cream with a high concentration of more than 15% can be used to treat corny eyes, callus and some other wart-like lesions.
Antibacterial: Salicylic acid has an inhibitory or killing effect on some bacteria, which helps to treat skin problems caused by excessive bacterial reproduction, such as the treatment of fungal infectious skin diseases such as ringworm on the hands and feet.
Beauty and skin care:
Exfoliation: Salicylic acid has the function of cuticle separation, which can remove the dead skin cells accumulated on the surface of the skin, promote skin metabolism, and make the skin more smooth and delicate.
Improve pore problems: It can penetrate deep into pores and dissolve the oil and dirt that clogs them, thus reducing the formation of pimples and blackheads, while helping to shrink pores.
Fade spots: can inhibit the formation of melanin, the pigmentation formed after the sun or inflammation has a certain improvement effect, to help improve the uneven skin color.
Acne treatment: Reduce the bacteria and inflammation on the skin surface, have a better therapeutic effect on acne, is the main ingredient in many acne products.
In the agricultural sector:
Improve crop quality and yield: most crop plants themselves contain a certain amount of salicylic acid, and external spray of low concentration of salicylic acid solution can promote the transpiration of crops, seed germination, flowering and fruit setting, etc., thus improving the quality and yield of crops.
Prevention and control of diseases, increase crop resistance: salicylic acid can promote the activity of a variety of enzymes in crops, indirectly kill harmful bacteria and some viruses, and improve the ability of crops to resist drought, cold and salt.
Preservation effect: under the right concentration, salicylic acid can prolong the flowering period of flowers, and extend the shelf life of fruits after harvest.
Chemical industry:
Rubber industry: used as anti-scorch agent and production of ultraviolet absorbent.
Electroplating or electroless plating: as an additive in some weakly acidic electrolytes, it can also be used as a complexing agent for electroplating or electroless plating.
Synthetic flavors: can be used to prepare methyl salicylate, salicylate ethyl ester and other synthetic flavors.
Other areas:
Food industry: Trace used in food, as a preservative.
Daily flavor: A small amount for the preparation of animal flavor and other daily flavor.
