Using DMI and Hydrogenated Lecithin Together

Yes, Dimethyl Isosorbide (DMI) and Hydrogenated Lecithin can generally be used together in the same cosmetic formulation.

• Penetration Enhancement: Both ingredients act as penetration enhancers, helping other active ingredients absorb better into the skin. DMI is a solvent that helps carry ingredients, particularly water-soluble ones, while Hydrogenated Lecithin, often used in liposomal structures or as an emulsifier, can also aid in delivery across the skin barrier.
• Moisturizing Benefits: Hydrogenated Lecithin is known for its moisturizing properties and contributes to a good skin feel, which aligns with your goal of seeking this benefit.
• Compatibility: DMI is soluble in various solvents including water, glycols, and oils. Hydrogenated Lecithin is typically dispersed in oil or used in emulsion systems. In a well-formulated emulsion (like a cream or lotion), both ingredients can be incorporated effectively.

Using both may provide a synergistic effect on penetration enhancement and ensure you gain the desired moisturizing benefits from the Hydrogenated Lecithin. Always ensure proper formulation techniques are followed for stability and efficacy.
