Potassium Sorbet

TL;DR. This ingredient is a preservative used mainly to inhibit yeast and mold growth in water-containing formulas. It performs best in acidic products such as gels, creams, shampoos, and toners.

What does Potassium Sorbet do in a cosmetic formula?

This ingredient is a preservative used mainly to inhibit yeast and mold growth in water-containing formulas. It performs best in acidic products such as gels, creams, shampoos, and toners.

Is Potassium Sorbet clean?

It is broadly accepted in clean-beauty frameworks because it has a long safety record, low use levels, and generally low irritation potential. Sensitivity is possible in some leave-on formulas, especially at low pH, but it is not a major restricted-list concern.

Is Potassium Sorbet sustainable?

This material is usually made synthetically from simple petrochemical-derived feedstocks, so its sourcing is not typically renewable. It is readily biodegradable and is not expected to bioaccumulate, which gives it a favorable end-of-life profile.

Is Potassium Sorbet COSMOS-approved?

It is permitted under COSMOS-natural and COSMOS-organic standards as an approved preservative when used within regulatory limits. From a Green Chemistry view, it scores well on low effective use levels and biodegradability, with the main tradeoff being conventional synthetic feedstock origin.

How does Potassium Sorbet work chemically?

The molecule is a water-soluble salt of an unsaturated C6 carboxylic acid, and preservative performance depends on formation of the protonated acid form, so activity is strongest below about pH 5.5 to 6. It is commonly used around 0.1 to 0.3%, often paired with other preservative hurdles, and it should be fully dissolved in the water phase.
