Galactaric Acid ●
TL;DR. This ingredient is mainly used as a chelating and pH-adjusting acid, helping bind metal ions and tune formula acidity. It can support clarity, stability, and performance in water-based skin and hair products.
What does Galactaric Acid do in a cosmetic formula?
This ingredient is mainly used as a chelating and pH-adjusting acid, helping bind metal ions and tune formula acidity. It can support clarity, stability, and performance in water-based skin and hair products.
Is Galactaric Acid clean?
From a clean-beauty perspective, it is generally low concern and not a common restricted-list ingredient. As with other acidic materials, comfort depends on final formula pH and use level, especially in leave-on products.
Is Galactaric Acid sustainable?
This material is typically made from plant-derived carbohydrate feedstocks or other bio-based sugar sources. It is expected to be biodegradable and does not raise the persistence or bioaccumulation concerns associated with many synthetic film-formers or silicones.
Is Galactaric Acid COSMOS-approved?
It is generally compatible with COSMOS-natural and COSMOS-organic approaches when sourced and processed through permitted natural-derivation routes. Its fit with Green Chemistry is strong when made from renewable feedstocks using controlled oxidation and purified without high-concern solvents.
How does Galactaric Acid work chemically?
The molecule is a sugar-derived dicarboxylic acid with multiple hydroxyl groups, which gives it strong polarity and metal-binding behavior. In formulas, it is used at low functional levels and performs best in aqueous systems where pH, neutralization, and solubility are managed by the formulator.
