Potassium Phosphate
Roles: Buffering
Potassium Phosphate is an inorganic salt commonly used in cosmetics and skincare formulations. While it’s not a “hero ingredient” like niacinamide or ceramides, it plays important supporting roles that help a product stay stable, comfortable on the skin, and effective.
Potassium Phosphate (often listed as Dipotassium Phosphate or Monopotassium Phosphate depending on its form) is a buffering and chelating agent. In skincare chemistry, it helps regulate and maintain a product's pH balance — a crucial factor for both stability and skin compatibility. It helps to achieve PH balance by preventing the formula from becoming too acidic or too alkaline over time.
Main Functions:
pH Buffering Agent - Its primary purpose is to stabilize pH. Many active ingredients — such as niacinamide, ceramides, or hyaluronic acid — perform best within a particular pH range. Potassium Phosphate ensures they stay effective throughout the product’s shelf life.
Stabilizer for Emulsions - In creams and lotions, it helps maintain the stability of emulsions (the blend of water and oils), preventing unwanted separation.
Enhances Product Comfort - A stable pH often means better skin tolerance. By keeping the formula balanced, Potassium Phosphate indirectly helps reduce the risk of stinging, redness, and irritation, especially in sensitive skin.
Supports Ingredient Performance - Some actives can lose potency if the formula drifts out of range. Potassium Phosphate keeps the environment optimal, protecting their performance.
Butylene Glycol is a very popular synthetic alcohol. It helps the product to absorb deeper and faster. It is also a solvent for other ingredients. As for the skin benefits, it helps to attract water and helps to make the skin softer.

Citric Acid is one of the AHAs and it is a super useful component! It’s a great antioxidant. It acts as a soft peeling that removes dead cells and kills bacteria. It becomes even more effective if used with other cosmetic acids. Combined formulations are more active, but can irritate sensitive skin if used too often. The component can also whiten the skin and remove dark areas.
It can be an irritator due to its naturally lower pH level of 2.2. But manufacturers also use it as a pH adjuster so in most cases you will not have any issues.
