Sodium Succinate
What Sodium Succinate is & what it does
Sodium Succinate is the sodium salt of succinic acid, a small organic acid that occurs naturally in the body and in many plants. In skincare and sunscreen formulas it is used mainly as a buffering agent to help stabilize and adjust the product's pH. It is a water-soluble ingredient that supports overall formula stability rather than acting on the skin directly.
What does Sodium Succinate do in skincare?
Sodium Succinate is the sodium salt of succinic acid and is used mainly as a buffering agent. Its job is to help set and stabilize a formula's pH so the product stays consistent. It works on the formula rather than acting directly as a skin treatment.
Is Sodium Succinate safe?
Sodium Succinate is used in small amounts as a pH buffer and is generally regarded as suitable for that role in cosmetics. Succinic acid and its salts occur naturally in the body and in many foods. For specific concerns it is best to consult a qualified professional.
Is Sodium Succinate natural or synthetic?
Succinic acid, from which this salt is made, occurs naturally in plants and in the body, but the cosmetic-grade ingredient is typically produced through manufacturing for purity and consistency. It can therefore be described as nature-identical depending on how it is sourced.
