Sodium Gluconate ●
TL;DR. This ingredient is primarily a chelating agent, binding trace metal ions that can discolor formulas, destabilize emulsions, or accelerate oxidation. It is often used to support preservative performance and improve formula clarity and stability.
What does Sodium Gluconate do in a cosmetic formula?
This ingredient is primarily a chelating agent, binding trace metal ions that can discolor formulas, destabilize emulsions, or accelerate oxidation. It is often used to support preservative performance and improve formula clarity and stability.
Is Sodium Gluconate clean?
It is generally well-tolerated, low in irritation potential, and has little clean-standard friction. Clean frameworks often view it as a more acceptable alternative to less biodegradable chelators.
Is Sodium Gluconate sustainable?
This material is commonly made from fermented plant-derived sugar feedstocks, then neutralized into a water-soluble salt. It is readily biodegradable and does not raise major persistence or bioaccumulation concerns.
Is Sodium Gluconate COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic when sourcing and processing meet the standard. Its fermentation-based origin, biodegradability, and low-use chelation role fit well with Green Chemistry principles.
How does Sodium Gluconate work chemically?
The molecule is a highly water-soluble, ionized six-carbon hydroxycarboxylate that coordinates metal ions through its carboxylate and hydroxyl groups. Typical use is about 0.05% to 0.5%, with good stability across common cosmetic pH ranges and frequent pairing with preservatives, antioxidants, and surfactant systems.
