Dimethyl Isosorbide

Description

Dimethyl Isosorbide (DMI) is a versatile and highly effective solvent and penetration enhancer widely used in skincare and cosmetic formulations. This clear, colorless liquid is derived from renewable resources, specifically corn-based isosorbide, making it an eco-friendly alternative to petroleum-based solvents.

DMI's unique molecular structure allows it to dissolve both water-soluble and oil-soluble ingredients, enhancing the stability and efficacy of various skincare formulations. Its primary function is to improve the penetration of active ingredients through the skin's barrier, increasing their bioavailability and overall effectiveness.

Key benefits of DMI include its ability to enhance the solubility of challenging ingredients, improve product texture, and reduce tackiness in formulations. It is particularly useful in sunscreen products, where it can help create more uniform and stable dispersions of UV filters.

DMI is non-irritating, non-sensitizing, and has a low potential for toxicity, making it suitable for a wide range of skin types. Its compatibility with numerous cosmetic ingredients allows formulators to create innovative and high-performance skincare products that deliver active ingredients more efficiently to the skin.
