Abstract: There is disclosed a composition comprising a water-insoluble thermoplastic compound capable of stimulating collagen synthesis (CSSC), the CSSC having a molecular weight of more than 0.6 kDa and being dispersed in a polar carrier as nano-elements having an average diameter of 200 nm or less and a viscosity of 107 mPa·s or less. The nano-elements of CSSC can be capable of stimulating the synthesis of skin proteins and/or enabling the delivery of active agents upon their application to a surface to be treated therewith. Methods for preparing the compositions and uses thereof are also provided.

Abstract: Aqueous inkjet ink formulations comprising a solvent including water and a co-solvent, a water soluble or water dispersible polymeric resin and a colorant, and a method for facilitating the use of such an aqueous inkjet ink in an indirect printing system in which the ink is jetted onto a hydrophobic release layer of an intermediate transfer member before having the solvent removed therefrom and being transferred to a substrate, wherein prior to the jetting of the ink the release layer is brought into contact with an aqueous solution of a positively charged polymeric chemical agent. Other aspects are also described.
