Potassium Hyaluronate is the potassium salt of hyaluronic acid and is a specialty cosmetic ingredient used primarily in skin-conditioning and hydration-focused personal-care formulations. Its INCI name is POTASSIUM HYALURONATE. It belongs to the hyaluronate family of glycosaminoglycan polymers and is structurally related to Hyaluronic Acid and Sodium Hyaluronate.
Potassium Hyaluronate is generally supplied as a white to almost-white powder or crystalline material. Commercial grades are hygroscopic and water soluble. Because it is a polymeric hyaluronate rather than a conventional small molecule, its molecular weight is expressed as a grade-specific range rather than one universal molecular-weight value.
The potassium salt form provides a different counter-ion from Sodium Hyaluronate while retaining the fundamental hyaluronate polymer structure. This makes Potassium Hyaluronate a useful alternative hyaluronate material for formulators developing specialized cosmetic products.
Potassium Hyaluronate is identified by CAS Number 31799-91-4 and is also known as Hyaluronic Acid Potassium Salt or Potassium Hyaluronate. Cosmetic ingredient references define it as the potassium salt of hyaluronic acid and identify its primary cosmetic function as skin conditioning.
The material is polymeric, so there is no single molecular formula or molecular weight that accurately represents every commercial cosmetic grade. Public chemical databases may display formulas for particular molecular representations or fragments, but these should not be presented as the molecular weight of a commercial high-molecular-weight Potassium Hyaluronate polymer.
Commercial bacterial-derived material is available with a molecular weight of minimum 8,000 Da calculated on the dried substance, demonstrating the importance of specifying molecular weight for the exact grade. Other grades and biological sources can have different molecular-weight distributions.
Potassium Hyaluronate should also be distinguished from Sodium Hyaluronate, Hydrolyzed Sodium Hyaluronate and Hydrolyzed Hyaluronic Acid. Although these ingredients belong to the same hyaluronate family, their counter-ion, molecular-weight distribution and processing characteristics can differ.
Potassium Hyaluronate is principally used as a skin-conditioning cosmetic ingredient. Its hyaluronate polymer structure provides strong interaction with water and contributes to the hydration characteristics of suitable cosmetic formulations.
The molecular weight of the material is an important functional parameter. Higher-molecular-weight grades generally have different viscosity and film-forming behavior compared with lower-molecular-weight grades. Therefore, the molecular-weight specification should be established according to the intended formulation.
Potassium Hyaluronate can also contribute to the sensory characteristics of aqueous cosmetic products by influencing viscosity and hydrated-film properties. The actual performance depends on molecular weight, concentration, pH, ionic strength, processing conditions and the other polymers or electrolytes present.
Potassium Hyaluronate can be considered for a variety of skin-care and personal-care formulations, including moisturising creams, facial serums, lotions, gels, essences, masks and other hydration-focused products.
Its water solubility makes it suitable for aqueous formulation systems. Because the polymer is hygroscopic, controlled dispersion and hydration are important during manufacturing. Gradual addition and sufficient hydration time can help produce a consistent solution or dispersion.
Different molecular-weight grades can be selected according to the desired viscosity and formulation characteristics. A high-molecular-weight Potassium Hyaluronate grade may provide different rheological behavior from a lower-molecular-weight grade.
The ingredient can also be formulated alongside other humectants, skin-conditioning ingredients and hyaluronate derivatives. Compatibility should be assessed in the finished formulation, particularly where high concentrations of electrolytes or other charged polymers are present.
Molecular weight and moisture content are key technical specifications for Potassium Hyaluronate. A commercial bacterial-derived specification reports molecular weight minimum 8,000 Da calculated on the dried substance and loss on drying maximum 20.0%. These values belong to that particular commercial grade and should not be treated as universal limits for every Potassium Hyaluronate product.
The Assay (HPLC) field should not be populated with an arbitrary percentage. As a polymeric cosmetic ingredient, Potassium Hyaluronate is better characterized through molecular weight, molecular-weight distribution, moisture, polymer content, viscosity and other applicable quality parameters.
Some commercial analytical references report assay values around 95–100%, but the analytical basis and grade must be confirmed before using such a value in a cosmetic specification. It should not automatically be represented as an HPLC assay.
Potassium Hyaluronate is hygroscopic and should therefore be stored in appropriately closed packaging under controlled conditions. Moisture uptake can affect powder handling, loss-on-drying results and hydration behavior.
Potassium Hyaluronate is a specialty cosmetic ingredient for manufacturers developing hydration-focused and skin-conditioning products. Its potassium-salt structure provides an alternative to Sodium Hyaluronate while retaining the characteristic polymeric nature of hyaluronate.
For B2B cosmetic raw-material sourcing, the specification should clearly identify CAS number, source, molecular-weight range, moisture, polymer content, appearance, solubility and applicable microbiological and elemental specifications.
As a Potassium Hyaluronate Cosmetic Ingredient Manufacturer in India, the focus is on controlled molecular-weight grades, consistent raw-material quality and suitability for bulk cosmetic and personal-care formulation requirements.
