Gluconic Acid ●
TL;DR. This ingredient primarily functions as a pH adjuster and mild chelating agent, helping formulas sit in the intended acidity range while binding metal ions that can affect color, odor, or stability. It may also contribute gentle exfoliating and humectant properties in water-based skin care.
What does Gluconic Acid do in a cosmetic formula?
This ingredient primarily functions as a pH adjuster and mild chelating agent, helping formulas sit in the intended acidity range while binding metal ions that can affect color, odor, or stability. It may also contribute gentle exfoliating and humectant properties in water-based skin care.
Is Gluconic Acid clean?
From a clean beauty perspective, this ingredient is generally well tolerated and not a common restricted-list issue. Like other acids, it can sting or feel irritating at higher levels or lower pH, especially on sensitive or compromised skin.
Is Gluconic Acid sustainable?
This material is commonly made from glucose through fermentation or controlled oxidation, often using plant-derived carbohydrate feedstocks. It is readily biodegradable and has low environmental persistence, with the main sustainability variable being the agricultural source of the sugar input.
Is Gluconic Acid COSMOS-approved?
It is generally compatible with COSMOS-natural and COSMOS-organic standards when made from permitted natural-origin feedstocks and allowed processing methods. Its renewable sourcing potential, water solubility, biodegradability, and mild processing profile fit well with Green Chemistry principles.
How does Gluconic Acid work chemically?
The molecule is a small, highly water-soluble sugar acid with multiple hydroxyl groups and one carboxylic acid group, with a pKa around 3.6. In formulas it is usually used as needed for pH adjustment or chelation, and performance depends strongly on final product pH, buffering system, and the presence of metal-sensitive ingredients.
