Discusses the wide-ranging applications of cyclodextrins beyond the pharmaceutical industry. We emphasize the versatility of cyclodextrins, which stems from their ability to form inclusion complexes with hydrophobic molecules, thereby improving their solubility, stability, and bioavailability.

Here are the key application areas discussed in the video and the podcast:

  • Dietary Supplements: Cyclodextrins are frequently used in dietary supplements to enhance the properties of various active compounds such as coenzyme Q10, cannabinoids, lipoic acid, curcumin, resveratrol, and fat-soluble vitamins (e.g., vitamin D). Clinical data supports the positive effects of certain cyclodextrins on lipid status and glycemic response. They can also be used to encapsulate complex systems like essential oils or natural extracts.
  • Food Industry: Cyclodextrins can function as dietary fibers and can modify the texture and palatability of foods. They can improve the shelf life of certain foods and reduce their glycemic index. Cyclodextrins are used to remove cholesterol from foods like butter and eggs. In baking, they can replace eggs due to their ability to create stable emulsions. Empty cyclodextrins are added to some seasoning salts to potentially prevent fat absorption. Gases can be encapsulated in cyclodextrins for controlled release in food packaging, or empty cyclodextrins can be included to remove unwanted odors. Alpha-cyclodextrin is suggested for reducing postprandial glycemic response when consuming starch.
  • Cosmetics: The cosmetic industry represents one of the largest global application areas for cyclodextrins. Hydroxypropyl beta-cyclodextrin is predominantly used here due to its superior solubility and stability compared to native cyclodextrins. They act as stabilizers, emulsifiers, and solubilizers, improving the bioavailability of cosmetic ingredients like vitamins and retinoids. Cyclodextrins can interact with skin cells, potentially enhancing permeation. They are also used for the controlled release of fragrances, odor masking, and to alleviate skin irritation. Major brands widely incorporate cyclodextrins in their cosmetic products.
  • Agriculture: Hydrophobic pesticides and insecticides can be encapsulated and stabilized with cyclodextrins for improved bioavailability. They can also be used to enhance the vitamin and nutrient content of bee feed and to alter the flesh color of certain animals when added to their feed.
  • Textile Industry: Cyclodextrins (potentially cyclodextrin derivatives) are used in the textile industry. Fragrances can be incorporated into fabrics using cyclodextrins for a sustained scent. During the COVID-19 pandemic, empty cyclodextrins were explored for incorporation into masks due to their antiviral effects.
  • Energy Industry: Research explores the use of cyclodextrins in the energy sector, including enhancing the capacity and longevity of lithium batteries.
  • Dentistry and Oral Hygiene: Cyclodextrins find applications in various dental products like toothpaste, mouthwashes, fillings, and cements, serving similar purposes as in other industries (e.g., active ingredient stability and release).
  • Space Industry: Due to their chiral nature, cyclodextrins are used as analytical tools in space missions, such as those to Mars, for separating amino acids and other similar molecules in the search for extinct life.
  • Environmental Applications: Cyclodextrins are being investigated for capturing carbon dioxide from the air. Cyclodextrin polymers have been developed and commercialized for filtering drinking water and wastewater, effectively removing PFAS compounds and drug residues.
  • Advanced Materials: Cyclodextrins serve as building blocks in various advanced materials, including coatings, car paints, 3D-printed materials, and medical devices. Polyrotaxanes, where cyclodextrins are threaded onto a molecular axle, are used in self-healing materials due to their unique flexibility and strength.

In conclusion, the discussion highlights the versatility of cyclodextrins and suggests that their applications are limited only by imagination, extending far beyond pharmaceuticals into numerous diverse industries. While dietary supplements, food, and cosmetics currently dominate the market, the potential for new applications across various sectors is immense.
