DIPOTASSIUM PHOSPHATE

Description

Dipotassium phosphate, also known as potassium phosphate dibasic, is a versatile inorganic compound widely used in skincare and cosmetic formulations. This water-soluble salt serves multiple functions, primarily as a pH buffer and stabilizer. Its ability to maintain a consistent pH level in products helps preserve their efficacy and extend shelf life.

In skincare, dipotassium phosphate acts as an emulsion stabilizer, preventing the separation of oil and water-based components. This property is crucial for maintaining the texture and consistency of creams, lotions, and serums. Additionally, it functions as a sequestering agent, binding to metal ions that could otherwise compromise product stability or cause skin irritation.

The ingredient also exhibits mild exfoliating properties, potentially aiding in gentle surface cell turnover. Its buffering capacity can help mitigate the potentially irritating effects of acidic ingredients, making it valuable in formulations containing alpha-hydroxy acids or vitamin C.

While generally considered safe for topical use, dipotassium phosphate may cause mild irritation in individuals with sensitive skin. Its concentration in skincare products is typically low, minimizing the risk of adverse reactions while maximizing its beneficial properties.
