Sustainable Shell Formulations as Alternative to the Conventional Soft Gelatin Capsules in Pharmaceutical and Nutraceutical Applications. A Review.

open access: yesMacromolecular Materials and Engineering, EarlyView.
In soft capsules (SCs), four crucial factors can modify the properties of the shell: the shell formulation, its interaction with the fill material, the SC production and its storage conditions. Gelatin is the most used gelling agent for SCs nowadays, but they have some drawbacks which can be solved including other alternative polymers in the shell ...

Surfactant‐Modified Progesterone‐Loaded PVP/Cellulose Fibres for Future Drug Delivery Applications in Menopause

open access: yesMacromolecular Materials and Engineering, EarlyView.
Surfactant‐modified progesterone‐loaded PVP/cellulose fibres present a novel transdermal drug delivery system for hormone replacement therapy in menopause. Electrospun ethyl cellulose and cellulose acetate matrices, optimised by inclusion of polysorbate 80, are studied via SEM, FTIR, rheology, and in vitro studies and found to have improved structure ...

Characteristics, properties and limitations of per‐ or polyfluoroalkyl substances (PFASs) and fluoropolymers

open access: yesPolymer International, EarlyView.
An overview and categorization of man‐made per‐ or polyfluoroalkyl substances (PFASs) including low‐molar‐mass and high‐molar‐mass fluorochemicals, and their international regulations is presented. Though certain PFASs are toxic, bioaccumulative and cross the human cellular membranes, others, such as fluoropolymers, are safe, reliable and involved in ...
