Cyclodextrin Bon Agent suspenseur/dispersant No known benefits Cyclodextrin at a glance Derived from cornstarch and made via biotechnology Used in cosmetics to stabilize and help solubilize key ingredients Has absorbent properties when used at higher levels Helps keep delicate ingredients protected from light, air, and heat Cyclodextrin description Cyclodextrin is a cyclic (that’s what the “cyclo” portion of its name means) complex sugar (dextran) known as a polysaccharide. It is obtained from plants and produced for cosmetics, foods, and pharmaceuticals via biotechnology involving a reaction between enzymes and cornstarch. Available in three different shapes depending on application need, cyclodextrin works in cosmetics as an absorbent, chelating agent, and more importantly helps stabilize, solubilize and ensure delivery of key ingredients to skin. For example, cyclodextrins can make water-soluble ingredients more oil-soluble, enhancing their penetration and bioavailability. They can also protect delicate ingredients from degradation due to light, air and heat exposure. As the sugars in the cyclodextrin break down, the ingredients contained inside their hollow center are released. Since cyclodextrin is a food-grade ingredient considered safe to consume, it is also deemed safe as used in cosmetics. It’s considered non-irritating and non-sensitizing. Usage levels in cosmetics vary depending on formulary goals and ingredients being encapsulated in the cyclodextrins. A typical usage range falls between 0.3–10%.
