Potassium Sorbate. Step 2: Water/Aqua/Eau ●
TL;DR. This ingredient is a preservative used mainly to control yeast and mold in water-containing formulas. It performs best in acidic systems, so it is common in toners, gels, shampoos, conditioners, and emulsions with adjusted pH.
What does Potassium Sorbate. Step 2: Water/Aqua/Eau do in a cosmetic formula?
This ingredient is a preservative used mainly to control yeast and mold in water-containing formulas. It performs best in acidic systems, so it is common in toners, gels, shampoos, conditioners, and emulsions with adjusted pH.
Is Potassium Sorbate. Step 2: Water/Aqua/Eau clean?
It is broadly accepted in clean-beauty frameworks and is not typically a restricted-list concern. Skin irritation potential is low at standard use levels, with sensitivity more likely in low-pH products or around the eye area.
Is Potassium Sorbate. Step 2: Water/Aqua/Eau sustainable?
This material is usually made by chemical synthesis rather than direct plant extraction, although it is used at very low levels. It is readily biodegradable and is not known for environmental persistence or bioaccumulation.
Is Potassium Sorbate. Step 2: Water/Aqua/Eau COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic standards as an allowed preservative. Its Green Chemistry fit is strongest on biodegradability and low-dose efficacy, while renewable sourcing is not usually its main advantage.
How does Potassium Sorbate. Step 2: Water/Aqua/Eau work chemically?
The molecule is an ionic potassium salt of a conjugated unsaturated carboxylate, and its preservative activity depends on the acid form present in the formula. Typical use is about 0.1% to 0.3%, with best performance below roughly pH 5.5 and weaker activity as pH rises.
