Sodium Benzoate Gluconolactone ●
TL;DR. This ingredient is primarily a water-soluble preservative system that helps protect formulas from bacteria, yeast, and mold. It can also contribute mild humectant and pH-supporting effects in water-based products.
What does Sodium Benzoate Gluconolactone do in a cosmetic formula?
This ingredient is primarily a water-soluble preservative system that helps protect formulas from bacteria, yeast, and mold. It can also contribute mild humectant and pH-supporting effects in water-based products.
Is Sodium Benzoate Gluconolactone clean?
It is widely accepted in clean-beauty frameworks and is generally well tolerated, with the main sensitivity watchpoint coming from very acidic finished formulas. Its performance depends on staying in an acidic pH range, so it is less suited to neutral or alkaline systems.
Is Sodium Benzoate Gluconolactone sustainable?
This material is typically made from a fermentation-derived sugar-acid component paired with a nature-identical aromatic acid salt that may come from petrochemical or synthetic routes. It is water soluble and readily biodegradable, with low persistence concerns at cosmetic use levels.
Is Sodium Benzoate Gluconolactone COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic standards when used within the standard’s preservative and formulation requirements. Its profile aligns well with Green Chemistry because it is effective at low use levels, biodegradable, and partly available from renewable fermentation feedstocks.
How does Sodium Benzoate Gluconolactone work chemically?
Chemically, this is a blend of an aromatic carboxylate salt and a cyclic ester of a sugar acid, giving preservative activity plus gradual acidification in water. Typical use levels are about 0.75% to 2.0%, with best preservative performance around pH 3.0 to 6.0 and improved efficacy as the formula becomes more acidic.
