Potassium Acetate is the potassium salt of acetic acid and is represented by the chemical formula C₂H₃KO₂. It is also known as Acetic Acid, Potassium Salt or Potassium Ethanoate. The substance has a molecular weight of 98.14 g/mol and is commonly supplied as a white crystalline powder or colourless, deliquescent crystals.
Potassium Acetate is a water-soluble salt that can be incorporated into aqueous formulation systems. Its chemical characteristics make it useful where controlled formulation conditions, buffering systems and specific functional properties are required. It is also recognized in cosmetic ingredient references, where its documented cosmetic function includes film forming.
Potassium Acetate is identified by CAS Number 127-08-2 and EC Number 204-822-2. Its molecular formula is C₂H₃KO₂, with a molecular weight of 98.14 g/mol.
The material is highly soluble in water and can also be freely soluble in ethanol. Depending on the grade and specification, Potassium Acetate may be supplied as a crystalline powder or deliquescent crystalline material. Because the material is hygroscopic/deliquescent, storage and handling conditions should be considered when maintaining its specified moisture characteristics.
USP-NF defines Potassium Acetate as containing 99.0–100.5% C₂H₃KO₂ on the dried basis. The USP assay is performed by titrimetry, using perchloric acid, rather than HPLC. Therefore, the USP assay range should not be incorrectly entered as an HPLC assay in a product specification.
Potassium Acetate can contribute functional properties to cosmetic and personal-care formulations. Cosmetic ingredient references identify it as a film-forming ingredient, meaning that it can contribute to formation of a film on the skin, hair or nails.
Its ionic and water-soluble characteristics can also make it useful when developing aqueous formulation systems requiring controlled salt composition. Potassium Acetate has additionally been documented in broader technical applications as a buffer and antimicrobial preservative, although the suitability of any preservative use in a finished cosmetic product depends on the applicable regulatory framework and formulation conditions.
The practical function of Potassium Acetate should therefore be determined according to the finished formulation, concentration, associated ingredients and target market requirements.
Potassium Acetate Cosmetic Ingredient can be considered for skin-care, hair-care, personal-care and other aqueous cosmetic formulation systems where its documented ingredient functionality is relevant.
Its high water solubility allows it to be incorporated into water-based formulations relatively easily. Formulators may evaluate it in systems where a soluble potassium salt is required or where film-forming characteristics are part of the formulation design.
Potassium Acetate can also be relevant to specialized formulation systems involving controlled ionic conditions. Its final use level should be established through formulation development, compatibility testing and stability studies rather than relying on a generic concentration.
For commercial cosmetic applications, formulators should also confirm the regulatory status and permitted function of Potassium Acetate in the intended market before final product development.
Potassium Acetate is very soluble in water, making aqueous processing straightforward. However, because it can absorb moisture from the environment, packaging, storage and handling should be appropriately controlled.
Quality evaluation can include identity, assay, loss on drying, pH, heavy metals, elemental impurities and other relevant chemical impurities. The applicable limits should correspond to the selected grade and specification.
A USP reference specifies a pH of 7.5–8.5 for a 1-in-20 solution and loss on drying of not more than 1.0%. A JECFA specification reports a broader pH range of 7.5–9.0 for a 1-in-20 solution and loss on drying of not more than 8.0% at 150°C for 2 hours. Because these specifications differ according to the standard and test conditions, the applicable specification should always be identified rather than combining values from different standards.
Potassium Acetate is a specialty ingredient that can be evaluated by cosmetic and personal-care manufacturers requiring a soluble potassium acetate material with defined technical characteristics. A reliable Potassium Acetate Cosmetic Ingredient Manufacturer in India can support formulation and procurement requirements with defined chemical identity and quality specifications.
As a Potassium Acetate manufacturer and supplier in India, Swapnroop can support bulk requirements for cosmetic raw materials and specialty ingredients. Product selection can be based on the intended application, required grade, hydration/moisture characteristics, analytical requirements and customer specification.
For commercial formulation development, clearly defined specifications and batch-level quality documentation are important for maintaining consistency across manufacturing operations.
