The crystallization temperature and polymorphism of tripalmitin nanoparticles in colloidal dispersions prepared by melt-homogenization and stabilized with different pharmaceutical surfactants (sodium glycocholate, sodium oleate, tyloxapol, Solutol HS 15, Cremophor EL) and their combinations with soybean phospholipid (Lipoid S100) were investigated to establish the influence of the emulsifiers o...

The architecture of polymer chains can play a significant role in their behavior at interfaces.

The aim. To study the biocomplex of surfactants based on rhamnolipids Pseudomonas sp. PS-17 (biocomplex PS) as an emulsifier and co-emulsifier by using method modelling composition emulsions for use in dermatology.
 Materials methods. PS is a biogenic surface-active complex synthesized bacteria genus Pseudomonas, which viscous mass that includes rhamnolipids, make up to 80 % biocomplex, we...

Study of cellulase adsorption on indigo particles and insoluble cellulose, as well as experiments on indigo interaction with immobilized amino acids together with theoretical analysis of three-dimensional structures of enzyme molecules, provided an evidence that certain cellulases, which have hydrophobic domains (clusters of closely located aromatic and non-polar residues) on their surface, may...

Dermatologically used topical products contain active ingredients and excipients, the latter including, for example, preservatives, surfactants, emollients, emulsifiers, and fragrances. Some computer databases aid in the prescription of topical products to patients who are allergic to specific ingredients; for example, the Contact Allergen Management Program and Contact Allergen Replacement Dat...

Piceatannol (E-3,5,3',4'-tetrahydroxystilbene) is a phytoalexin synthesized in grapes in response to stress conditions. It exhibits strong antioxidant and antileukaemic activities due to the presence of the catechol moiety. To modify some physical properties like solubility, and miscibility in non-aqueous media some new previously unreported piceatannol derivatives having lipophilic chains on t...
