Potassium Aspartate ●
TL;DR. This ingredient is mainly used as a humectant and skin-conditioning amino-acid salt, helping bind water and support a hydrated feel. It can also contribute mild buffering and electrolyte character in water-based formulas.
What does Potassium Aspartate do in a cosmetic formula?
This ingredient is mainly used as a humectant and skin-conditioning amino-acid salt, helping bind water and support a hydrated feel. It can also contribute mild buffering and electrolyte character in water-based formulas.
Is Potassium Aspartate clean?
It has a low-profile clean-beauty standing: non-fragrance, not a common allergen, and not typically flagged on restricted lists. As an amino-acid-derived salt, it is generally well tolerated, with irritation risk mainly tied to overall formula pH and concentration.
Is Potassium Aspartate sustainable?
This material is typically made by neutralizing a fermentation- or synthesis-derived amino acid with a mineral alkali, so sourcing can be renewable or mixed depending on supplier. It is water soluble and expected to be readily biodegradable with low environmental persistence.
Is Potassium Aspartate COSMOS-approved?
It is generally compatible with COSMOS-natural and COSMOS-organic when made from permitted feedstocks and approved neutralization chemistry, but documentation depends on supplier origin and process. Its Green Chemistry fit is strong when fermentation-derived, due to aqueous processing, biodegradability, and low environmental persistence.
How does Potassium Aspartate work chemically?
The molecule is an ionic, water-soluble amino-acid carboxylate salt with a mineral cation, so it partitions into the aqueous phase and does not behave like an oil-soluble emollient. Use levels are typically low, often around 0.1-2% in leave-on hydration or conditioning systems, and it is most stable in mildly acidic to neutral formulas.
