Definitions
- the propylene oxide: anhydroglucose molar ratio used is chosen from a range going from 0.70: 1.00 to 0.86: 1.00;
- This chloride content can be conventionally determined by a person skilled in the art by potentiometric titration of an h ⁇ CD solution using a silver nitrate solution of known concentration.
- the HPpCD according to the invention has a pH in a range from 5.0 to 7.5; said pH being measured on the basis of a solution of HP CD consisting of 2 g of dry HP CD, 98 g of distilled water and 0.3 ml of a potassium chloride solution at 225 g / L .
- the propylene oxide: anhydroglucose molar ratio used is greater than or equal to 0.75: 1.00, preferably greater than or equal to 0.80: 1.00, preferably greater than or equal to 0.82: 1.00, preferably greater than or equal to 0.84: 1.00, preferably equal to 0.85: 1, 00.
- the invention also relates to the use of an HRbO ⁇ according to the invention as an excipient, and / or for encapsulating a substance, and / or solubilizing a substance in an aqueous medium, and / or for improving the chemical stability of a substance , and / or to improve the delivery of a substance to and through biological membranes, and / or to increase the physical stability of a substance, and / or to formulate a substance from a liquid form to a pulverulent form , and / or to prevent interactions of a substance with another substance, and / or to reduce local irritation after topical or oral administration of a substance, and / or to prevent absorption of a substance by level of certain tissues such as the skin, and / or to obtain a prolonged release of a substance, and / or to mask the taste of a substance, in particular its bitterness, and / or to mask the smell of a substance , and / or for mo identify the bioavailability of a substance.
- these substances are lipophilic compounds or carriers of at least one lipophilic group.
- the bleaching step was carried out by treatment with active charcoal for 1 h at 70 ° C.
- the medium was then filtered through a bag filter and then a cartridge filter 1 ⁇ m then 0.22 ⁇ m.
- the membrane purification step was carried out using a nanofiltration module equipped with a membrane having a cutoff threshold of less than 800 Da, at a pressure of less than 35 bars and at a temperature of more than 45 ° C. .
- the propanediol content of the retentate was checked by HPLC assay. The nanofiltration operation was stopped as soon as a propanediol content of less than 0.1% by weight on dry product was reached.
