Cyclodextrin incorporated silicone materials and their use as carriers for actives

today’s cyclodextrin is an innovation from WACKER (Amitabha MitraMegan GutmanChristian Hartman and Vera Popova) where cyclodextrins are part of a silicone composition creating articles for absorption, encapsulation and delivery of actives and other compounds. Example of such articles could be transdermal patches, PSAs, medical device, membranes, gels, clothing or other wearable materials, etc. The invention can be used for various applications including cosmetics, medical, home care, textiles, industrial and others.


Thermal response liquid intelligent window and preparation method

today’s cyclodextrin is something smart and unique – heat-responsive, intelligent window. In practice, temperature-sensitive cyclodextrin as a solute and water and glycerol as solvents are injected into an interlayer of a double-layer window panel to obtain the thermal response liquid intelligent window. The thermal response liquid intelligent window is prepared from safe, non-toxic and environment-friendly raw materials through a simple and feasible preparation method in accordance with the green and environment-friendly concept. The window is remarkable in anti-freezing capability, is high in transparency in a cold state, is high in response speed after being heated, is quickly turned into an opaque state, and can effectively modulate the sunlight transmittance.

Aggregation Behavior of Cyclodextrin-Based [3]Rotaxanes

Today’s #cyclodextrin:
I have shared several papers and patents already on the fascinating and widespread applications of rotaxanes, from cosmetics through drug delivery to advanced materials.
In this paper Yosuke Akae and Patrick Theato report on an important practical aspect of their use, particularly on the aggregation of cyclodextrin (CD)-based [3]rotaxane, which forms a hexagonal packing type aggregation derived from hydrogen bond formation among CD units in a similar manner to polyrotaxane species. This aggregation could be controlled by solvent type on dispersion treatment, axle end structures, and modification of CD.
