DISODIUM PHOSPHATE

Description

Disodium phosphate is a versatile inorganic compound widely used in skincare formulations and cosmetic products. This salt of phosphoric acid serves multiple functions, including acting as a buffering agent, pH adjuster, and emulsion stabilizer. In skincare, disodium phosphate helps maintain the optimal pH balance of products, ensuring their effectiveness and stability.

As a buffering agent, disodium phosphate prevents sudden changes in pH levels, which is crucial for preserving the integrity and efficacy of active ingredients. It also aids in controlling the product's acidity, making it compatible with the skin's natural pH. This property is particularly beneficial in cleansers and toners, where maintaining a balanced pH is essential for skin health.

In addition to its pH-regulating capabilities, disodium phosphate acts as an emulsion stabilizer, helping to create smooth, consistent textures in creams and lotions. It also functions as a sequestering agent, binding to metal ions that could potentially degrade the product or cause skin irritation. While generally considered safe for topical use, disodium phosphate is typically used in low concentrations in skincare formulations to minimize any potential for irritation.
