Potassium Sorbate Organic ●
TL;DR. This ingredient is used as a preservative, mainly to control yeasts and molds in water-based personal care formulas. It is most useful in acidic products such as gels, lotions, toners, and rinse-off formulas.
What does Potassium Sorbate Organic do in a cosmetic formula?
This ingredient is used as a preservative, mainly to control yeasts and molds in water-based personal care formulas. It is most useful in acidic products such as gels, lotions, toners, and rinse-off formulas.
Is Potassium Sorbate Organic clean?
It is broadly accepted in clean-beauty standards as a low-level preservative with a long safety record. Sensitivity is uncommon, though acidic formulas and higher use levels can sting compromised skin.
Is Potassium Sorbate Organic sustainable?
This material is typically produced as a nature-identical synthetic ingredient rather than extracted at scale from plants. It is readily biodegradable, used at low concentrations, and has low concern for environmental persistence.
Is Potassium Sorbate Organic COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-it as an approved preservative when used within standard limits. It fits Green Chemistry reasonably well because it is effective at low dose, biodegradable, and does not require heavy solvent systems in finished formulas.
How does Potassium Sorbate Organic work chemically?
The molecule is an ionic salt with a conjugated unsaturated carboxylate structure, and it performs best when enough of it is converted to its active protonated form in acidic conditions. Typical use levels are about 0.1% to 0.3%, sometimes up to 0.6%, with strongest performance below pH 6.5 and common pairing with other preservative systems for broader bacterial coverage.
