Ashland™ Progressive Preservatives

Optiphen™ - A Progressive Approach

Optiphen™ preservatives from Ashland™ offer progressive benefits for personal care formulations. They are compatible with a variety of formulations and are free from parabens, formaldehyde-donors, halogens, and Methylisothiazolinone (MIT). These preservatives offer many great benefits; most of which include effectiveness against gram-positive and gram-negative bacteria, yeast, and mold; excellent heat stability; water soluble; and efficacy in a wide pH range.
