Sodium Phosphate
What Sodium Phosphate is & what it does
A buffering salt used to adjust and stabilize a formula's pH. It keeps the product balanced and gentle.
Is Sodium Phosphate safe?
Sodium Phosphate is a common salt used in cosmetics mainly to adjust and stabilize pH, and it is generally regarded as safe at the levels used in formulas. It is widely used across personal care and other products. Sensitivity is uncommon, but as always you can patch test if your skin reacts easily.
What does Sodium Phosphate do in skincare?
Sodium Phosphate is primarily a buffering agent. It helps set and hold a product at a stable, skin-appropriate pH, which supports both comfort and the stability of other ingredients. It can also act as part of a buffering pair with related phosphate salts.
Is Sodium Phosphate vegan?
Sodium Phosphate is a mineral salt that is typically produced from inorganic sources, so it does not inherently require animal-derived materials and can suit vegan formulas. Final vegan status depends on the whole formula and the brand's sourcing. Check the product's vegan labeling if this matters to you.
