20110200666 | UV PROTECTION AGENT FOR THE SKIN OR HAIR HAVING A UV FILTER SUBSTANCE ENCAPSULATED IN A VESICULAR CARRIER SYSTEMu - To provide a UV protection agent for topical application to the skin or hair with a very high UV filter substance concentration and good adhesion to skin and hair in accordance with the invention there is proposed a UV protection agent having at least one UV filter substrate encapsulated in a vesicle carrier system, wherein the UV protection agent is characterised in that the at least one UV filter substance encapsulated in the vesicular carrier system is soluble in oil and the vesicular carrier system comprises vesicles which are made up of hydrophobised polysaccharides and are of a particle size of between 10 and 1000 nm and have a positive surface charge with a zeta potential in the range of between 1 and 150 mV. In addition there is proposed the use of such a UV protection agent in suitable cosmetic and/or pharmaceutical formulations. | 08-18-2011 |
20110229535 | COMPOSITION HAVING A SIRTUIN ACTIVATOR - The present invention concerns a composition having at least one sirtuin activator and a carrier system for the at least one sirtuin activator, wherein the carrier system includes lipid vesicles with one or more lipid membranes. To provide an improved action of sirtuin activators in living skin cells, it is proposed in accordance with the invention that the at least one sirtuin activator is contained in the lipid vesicles and the lipid vesicles have a positive surface charge, wherein the positive surface charge is afforded by the lipid vesicles in the lipid membrane or membranes in addition to the lipids from which the vesicles are made up having positively charged molecules as charge generators, wherein said charge generators are selected from quaternary ammonium compound | 09-22-2011 |
20110302725 | COSMETIC COMPOSITION FOR COLORING HAIR COMPRISING A DIRECT HAIR DYE AND A CARRIER SYSTEM COMPRISING POLYSACCHARIDES - The present invention concerns cosmetic compositions for coloring hair comprising at least one direct hair dye and a carrier system for the at least one direct hair dye, and the use of such compositions in cosmetic formulations for coloring hair. To provide a possible way with which the permanence of the bond of direct hair dyes to the hair can be improved, with the aim of direct dyes remaining on the hair for as long as possible to deliver the desired hair color in the desired quality for as long as possible, according to the invention there are proposed compositions of the aforementioned kind in which the carrier system is vesicular and comprises vesicles which are made up from hydrophobised polysaccharides and have a particle size of between 10 and 1000 nm as well as a positive surface charge with a zeta potential in the range of between 1 and 150 mV. | 12-15-2011 |
20110302726 | COSMETIC COMPOSITION FOR COLORING HAIR COMPRISING A DIRECT HAIR DYE AND A CARRIER SYSTEM COMPRISING LIPID VESICLES - The present invention concerns cosmetic compositions for coloring hair comprising at least one direct hair dye and a carrier system for the at least one direct hair dye, the use of such compositions in cosmetic formulations for coloring hair and processes for the production of the compositions. To provide a possible way with which the permanence of the bond of direct hair dyes to the hair can be improved, with the aim of direct dyes remaining on the hair for as long as possible to deliver the desired hair color in the desired quality for as long as possible, according to the invention there are proposed compositions of the aforementioned kind in which the carrier system includes lipid vesicles having one or more lipid membranes, wherein the at least one direct hair dye is contained in the lipid vesicles and the lipid vesicles have a positive surface charge, wherein the positive surface charge is caused by the lipid vesicles in the lipid membrane or membranes in addition to the lipids from which the vesicles are made up having positively charged alkyl trimonium salts as charge generators. | 12-15-2011 |
