progressive preservatives

As personal care product manufacturers sell to an increasingly global client base, they need approved ingredients to easily navigate regulatory hurdles. Ashland’s family of progressive preservatives featuring the Optiphen™ preservative and Rokonsal™ preservative product lines is approved for use in all major markets, compatible with a variety of formulations and not based on paraben, formaldehyde or halogens. Effective against gram-positive and gram-negative bacteria, yeast and mold, they offer excellent heat stability, work across a wide pH window and are easily incorporated in cosmetic formulations.
