Diols can influence the overall microbial stability due to their water binding properties. They are widely used in skin care, hair care, wet wipes, toiletries and color cosmetics. With their moisturizing and solubilizing properties they are considered to be multifunctional. Their neutral smell and wide pH tolerance makes them suitable for many applications. In emulsions the Diols should be added at the post-emulsification stage, to enhance their availability at the water/oil interface.
