What is Dulbecco’s Phosphate Buffered Saline?
Dulbecco’s Phosphate Buffered Saline (DPBS) is a buffer solution that plays a crucial role in various cosmetic formulations. It is composed of Potassium Chloride, Potassium Phosphate, Sodium Chloride, and Sodium Phosphate, but notably, it does not contain calcium or magnesium. This specific composition helps maintain the pH balance of cosmetic products, ensuring they remain stable and effective over time.
DPBS has its roots in the scientific community, originally formulated by Renato Dulbecco, an Italian-American virologist who made significant contributions to cell culture techniques. Over time, its utility extended beyond the laboratory and into the world of cosmetics, where its buffering capabilities became highly valued. The transition from a purely scientific tool to a cosmetic ingredient highlights its versatility and effectiveness in maintaining product integrity.
The production of Dulbecco’s Phosphate Buffered Saline involves dissolving the specific salts—Potassium Chloride, Potassium Phosphate, Sodium Chloride, and Sodium Phosphate—in purified water. The solution is then carefully adjusted to achieve the desired pH level, typically around 7.4, which is close to the natural pH of human skin. This meticulous process ensures that DPBS can effectively stabilize cosmetic formulations without causing irritation or adverse reactions.
