Sodium Phosphate
Explained
Sodium Phosphate is is behind-the-scenes formulation helper. Its main job is buffering, or locking in the product's pH.
This helps ensure the formula stays at its intended acidity through manufacturing, shipping, and sitting on your shelf. Many active ingredients like vitamin C or retinoids are pH sensitive so maintaining their happy pH range matters.
It is synthetic and reported use concentrations are very low (up to 0.086% in face powders).
