Sodium Carbonate
What Sodium Carbonate is & what it does
An alkaline mineral salt used to adjust pH. It helps keep a formula balanced and stable.
Is Sodium Carbonate safe?
Sodium Carbonate, also called soda ash, is used in cosmetics mainly as a pH adjuster at low levels and is generally regarded as safe for that purpose. In concentrated form it is alkaline, so formulators use it in small, buffered amounts. If you have specific concerns, a professional can advise.
What does Sodium Carbonate do in skincare?
Sodium Carbonate functions chiefly as a pH adjuster and buffering agent, helping bring a formula to its target acidity or alkalinity. It can also act as a mild bulking or cleansing aid in some products. It is a functional ingredient rather than a treatment active.
Is Sodium Carbonate natural or synthetic?
Sodium Carbonate occurs naturally as mineral deposits and can also be manufactured industrially, so cosmetic-grade material may be either mined or synthesized. Chemically the result is the same compound. Sourcing depends on the supplier.
