disodium phosphate

Description

Disodium phosphate is a versatile inorganic compound widely used in skincare and cosmetic formulations. This sodium salt of phosphoric acid serves multiple functions, including acting as a pH buffer, emulsifier, and chelating agent. In skincare products, disodium phosphate helps maintain optimal pH levels, crucial for product stability and skin compatibility. Its buffering capacity aids in neutralizing acidic or alkaline ingredients, ensuring a balanced formulation.

As an emulsifier, disodium phosphate assists in blending oil and water-based components, contributing to the smooth texture and consistency of creams and lotions. Its chelating properties help prevent mineral build-up and enhance product preservation by binding to metal ions that could otherwise compromise formula stability or efficacy.

Disodium phosphate is generally considered safe for topical use and is approved by regulatory bodies worldwide. It's particularly beneficial in formulations designed for sensitive or reactive skin types due to its mild nature. While primarily used for its functional properties, disodium phosphate may also offer indirect skincare benefits by enhancing the stability and effectiveness of active ingredients in a formulation. Its inclusion in skincare products underscores the importance of well-balanced, stable formulations in achieving desired skincare outcomes.
