Sodium Succinate ●
TL;DR. This ingredient is used mainly as a buffering and pH-adjusting salt, helping formulas hold a mildly acidic to neutral pH. It may also support skin-conditioning claims in water-based products.
What does Sodium Succinate do in a cosmetic formula?
This ingredient is used mainly as a buffering and pH-adjusting salt, helping formulas hold a mildly acidic to neutral pH. It may also support skin-conditioning claims in water-based products.
Is Sodium Succinate clean?
From a clean-beauty perspective, it is generally low-friction: well tolerated, not a common allergen, and not a standard restricted-list concern. Sensitivity is uncommon at typical cosmetic levels.
Is Sodium Succinate sustainable?
This material can be made from fermentation-derived or petrochemical feedstocks, with bio-based routes improving its sustainability profile. It is water soluble, readily biodegradable, and not known for environmental persistence or bioaccumulation.
Is Sodium Succinate COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic frameworks when made through allowed feedstocks and processing routes. Its simple salt chemistry, biodegradability, and potential renewable sourcing align well with Green Chemistry principles.
How does Sodium Succinate work chemically?
The molecule is a small dicarboxylate salt with two ionized carboxyl groups, which makes it highly water soluble and useful in buffer systems near conjugate-acid pKa values of about 4.2 and 5.6. It is typically used at low levels for pH control or skin-conditioning support, remains stable in ordinary aqueous cosmetic pH ranges, and has no oxidation-prone lipid chain.
