Salicylic acid powder is a common ingredient in skincare products due to its ability to exfoliate the skin and treat acne. It is available in powder form for use in various skincare formulations.
Salicylic acid powder is a white crystalline powder, odorless, and tastes slightly bitter before turning pungent. The melting point is 157-159 ℃, and it gradually changes color under light. The relative density is 1.44. The boiling point is about 211 ℃ /2.67kpa. Sublimation at 76 ℃. It is rapidly heated and decomposed into phenol and carbon dioxide under normal pressure. 1g salicylic acid can be dissolved in 460ml water, 15ml boiling water, 2.7ml ethanol, 3ml acetone, 3ml ether, 42ml chloroform, 135ml benzene, 52ml turpentine, about 60ml glycerol and 80ml petroleum ether, respectively. Adding sodium phosphate, borax, etc. can increase the solubility of salicylic acid in water. The pH value of salicylic acid aqueous solution is 2.4. Salicylic acid and ferric chloride aqueous solution form a special purple color.

Efficacy of Salicylic acid powder
Salicylic acid is generally able to resist fungi, keratinization and remove the aged cuticle of the skin.
1. Antifungal: salicylic acid can usually play an anti bacteriostatic role, inhibit fungi, and play a certain auxiliary role in the treatment of skin fungal infection or psoriasis.
2. Anti keratinization: salicylic acid can be directly applied to the affected area, can directly act on the cornea, and can promote the recovery of skin cornea.
3. Remove the aged stratum corneum: salicylic acid can usually soften the corneum after it is applied to the skin, which can remove the aged stratum corneum on the skin surface.
1. Used as a standard, fluorescent indicator, and complex indicator for alkali titration and iodine titration.
2. Used as a scorch retarder and in the rubber industry to produce ultraviolet absorbers and foaming agents.
3. Used as a complexing indicator, complexing masking agent, color developer and preservative for titanium, zirconium, tungsten ions.
4. As an additive in some weakly acidic electrolytes, it can also be used as a complexing agent for electroplating or chemical plating.
5. Used as a cosmetic preservative, mainly used in water-based cosmetics such as floral water, prickly heat water, and quinine head water. In addition to the antiseptic and bactericidal effects, it also has the functions of removing sweat odor, relieving itching and swelling, relieving pain and inflammation.
6. Used as a raw material in the pharmaceutical industry for the preparation of aspirin, sodium salicylate, salicylamide, analgesic, phenyl salicylate, and blood-preventing-67. The dye industry is used to prepare mordant pure yellow, direct brown 3GN, acid chrome yellow, etc. It is also used as a rubber vulcanization retardant and disinfectant preservative.
7. It is used as an accelerator for epoxy resin curing, as a preservative, and can also be used to prepare synthetic fragrances such as methyl salicylate and ethyl salicylate. It can also be used as a raw material for preparing direct dyes and acid dyes in the dye industry, and can also be used as a rubber anti-scorch agent, disinfectant, etc.
8. A small amount is used to prepare daily flavors such as animal flavors, and a trace amount is used in food to act as a preservative.
