Gluconolactone^ Sodium Benzoate Calcium Gluconate ●
TL;DR. This ingredient is a broad-spectrum preservative system for water-containing formulas, used to help control bacteria, yeast, and mold. It can also add mild humectant and chelating support that improves overall formula stability.
What does Gluconolactone^ Sodium Benzoate Calcium Gluconate do in a cosmetic formula?
This ingredient is a broad-spectrum preservative system for water-containing formulas, used to help control bacteria, yeast, and mold. It can also add mild humectant and chelating support that improves overall formula stability.
Is Gluconolactone^ Sodium Benzoate Calcium Gluconate clean?
From a clean-beauty perspective, this ingredient is generally well accepted because it has low sensitization potential and is commonly used in certified natural formulas. The main formulation caveat is pH, since very acidic products can feel more active or tingly on sensitive skin.
Is Gluconolactone^ Sodium Benzoate Calcium Gluconate sustainable?
This material is water soluble and its components are considered readily biodegradable, so it has a favorable end-of-life profile. Its supply chain can include carbohydrate-derived fermentation inputs along with nature-identical mineral and organic-acid chemistry.
Is Gluconolactone^ Sodium Benzoate Calcium Gluconate COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic when used within the standard’s preservative rules and normal concentration limits. It aligns well with Green Chemistry principles through effective low-dose use, biodegradability, water compatibility, and partial renewable feedstock origin.
How does Gluconolactone^ Sodium Benzoate Calcium Gluconate work chemically?
This material combines a polyhydroxy cyclic ester, an aromatic carboxylate salt, and a mineral salt of a sugar-derived acid. It is typically used at about 0.75 to 2.0% and performs best around pH 3 to 6, with stronger preservation as the formula moves below about pH 5.5.
