Methyl Cyclodextrin
What is Methyl Cyclodextrin?
Methyl cyclodextrin belongs to the cyclodextrin family, which consists of cyclic oligosaccharides enzymatically derived from starch. This version features methyl groups attached to enhance its water solubility and complexing properties. In cosmetics, it primarily serves in formulation stabilization, particularly as a chelating agent. It works by forming stable inclusion complexes with metal ions like iron or copper, which can otherwise trigger oxidation reactions leading to product degradation, color changes, or rancidity. Additionally, its cavity structure allows encapsulation of hydrophobic ingredients such as fragrances or oils, aiding controlled release and improved solubility in water-based products. This makes it valuable in cleansers, moisturizers, and serums where maintaining integrity over time is key.
