Moisture-rich cosmetic formulations require effective preservation to maintain microbial quality throughout their intended shelf life. For manufacturers developing creams, lotions, shampoos and other water-based products, preservative selection must account for microbial protection, formulation compatibility and regulatory requirements.
Nutrinova® Potassium Sorbate NXT, is a nature-identical preservative designed for personal care and cosmetic formulations with high water content. Its water solubility and antimicrobial properties make it a relevant option for manufacturers evaluating preservation systems.
Water-containing cosmetic products can provide conditions for microbial growth, making preservation an essential part of formulation development. Potassium sorbate is used to inhibit the growth of yeasts, moulds and certain bacteria. Its effectiveness depends on formulation conditions, particularly pH, making preservative selection and testing important when developing or modifying a product. For moisture-rich formulations, Nutrinova® Potassium Sorbate NXT offers a water-soluble preservative option that can be evaluated as part of an appropriate preservation system.
Nutrinova® Potassium Sorbate NXT is positioned for a range of moisture-containing products.

Replacing or selecting a preservative requires an assessment of the complete formulation rather than the preservative ingredient alone.
Selection Factor |
Why It Matters |
|---|---|
Formulation pH |
Sorbate efficacy is pH-dependent, making the finished product's pH an important selection criterion. |
Water content |
Determines the relevance of water-soluble preservation ingredients. |
Ingredient compatibility |
Helps establish whether the preservative is suitable for the complete formulation. |
Preservation efficacy |
Requires appropriate testing to confirm microbial protection in the finished product. |
Regulatory requirements |
Preservative selection must align with the applicable cosmetic regulations and intended market. |
