Potassium salicylate is the potassium salt of salicylic acid. Potassium
Salicylate is a cosmetic biocide and preservative, not currently in use.
It was used for the treatment of melasma and the daily use of sun protection.
White, odorless powder. Becomes pink on exposure to light. Soluble in water, alcohol. One gram dissolves in 0.85 mL H2O.
- Anti-virus
Potassium salicylate has a certain antiviral effect. Studies have shown that 1.0 M potassium salicylate inactivated 0.2 per cent solution of the pure tobacco mosaic virus at pH 7 and 30 ° C.
- Cosmetics
Potassium salicylate had been used to treat melasma, which is mild and less irritating to the skin. It was also an active ingredient in sunscreen. Other salicylic acid derivatives are now commonly used in cosmetics. Such as 2-Hydroxyethyl salicylate, which is often used in facial cleansers; And 4-methoxysalicylic acid, which can whitening the skin.
- Agriculture
Salinity and cadmium (Cd) contamination of soil are serious environmental issues threatening food security. With the addition of K, separately or in combination, quinoa plants were grown under NaCl and Cd stress. The activities of superoxide dismutase (SOD), catalase (CAT), peroxidase (POD), and ascorbate peroxidase (APX) when SA and K were applied together to the plants subjected to the joint stress of Cd and salinity. Based on the values of the bioconcentration factor (>1), the translocation factor (<1), and the higher tolerance index, it was clear that Cd-contaminated, salty soils could be stabilized with quinoa under the combined supply of SA and K.
