CDPetanolamin

CDPetanolamin is an organic quaternary ammonium compound that has been developed for use in water treatment and surface treatment applications. The molecule consists of a cyclodextrin core that is functionalized with a poly‑ethylene glycol chain and a terminal dimethylamine group, giving the compound a balanced amphiphilic character. The chemical formula is C31H56N2O8, and the substance is typically obtained through a two‑step synthesis that begins with the selective alkylation of 6‑(p‑tosyloxy)‑β‑cyclodextrin followed by base‑catalysed deprotection and quaternisation. The resulting product is a colourless, crystalline solid that is readily soluble in water and organic solvents such as ethanol and acetone.

Physical properties of CDPetanolamin include a melting point of 118–120 °C, a boiling point above 300 °C under reduced pressure, and a refractive index of 1.505 at 20 °C. The compound is stable under neutral and mildly alkaline conditions but decomposes at pH values below 3 or above 10, releasing volatile amine fragments that can cause irritation. Standard handling guidelines recommend the use of gloves and eye protection, and the storage of the material in a tightly sealed container kept in a cool, dry environment.

Industrially, CDPetanolamin functions as a high‑efficiency dispersant and flocculant in municipal and industrial wastewater treatment, improving the removal of heavy metals, dyes, and organic pollutants. In the cosmetic sector it is applied as a mild conditioning agent in shampoos and conditioners, owing to its ability to adsorb onto hair fibres and reduce static. Its biodegradability and low foaming tendency have also made it attractive for formulations in animal‑care products.

Safety data indicate that oral exposure to the compound can cause mild gastrointestinal irritation; the material is not classified as hazardous under the Globally Harmonised System but should be handled with ordinary safety precautions. Current research is exploring the potential of CDPetanolamin to serve as a delivery vector for targeted drug delivery and as a stabiliser in polymer ink formulations.
