<p>Solbrol PEH is a liquid cosmetic preservative blend used to help protect leave-on and rinse-off personal care products from microbial growth. It works in formulations with a final pH up to 8 and is suitable for a wide range of skin and hair care products. Because it is oil soluble, it is especially useful in anhydrous products that may come into contact with water during use.</p>
