Sorbate ●
TL;DR. This ingredient is primarily used as a preservative, especially to control yeast and mold growth in water-based products. It is often paired with other preservative agents for broader protection against bacteria.
What does Sorbate do in a cosmetic formula?
This ingredient is primarily used as a preservative, especially to control yeast and mold growth in water-based products. It is often paired with other preservative agents for broader protection against bacteria.
Is Sorbate clean?
From a clean-beauty perspective, it is generally accepted and has a long safety record at cosmetic use levels. The main caveat is mild irritation potential in sensitive skin or around the eyes, especially at higher concentrations or low pH.
Is Sorbate sustainable?
This material is readily biodegradable and does not raise major persistence or bioaccumulation concerns. It is commonly produced through industrial chemical synthesis, so its sustainability profile depends more on manufacturing inputs than on land-use pressure.
Is Sorbate COSMOS-approved?
It is permitted under COSMOS natural and organic standards as an approved preservative within allowed use limits. It fits Green Chemistry reasonably well because it is effective at low levels, biodegradable, and does not require high environmental persistence to perform.
How does Sorbate work chemically?
The molecule is an unsaturated six-carbon carboxylate that is most effective in its protonated form, so performance is strongest in acidic formulas, commonly below pH 6 and often around pH 4 to 5.5. Typical use levels are about 0.1 to 0.3 percent, and it is often combined with other preservation strategies to cover bacteria as well as yeast and mold.
