| 摘要 |
<p>The invention concerns a dermal or transdermal application system containing a matrix based on a hydro-alcohol gel, characterised in that it contains at least an iota carragheenate with molecular weight ranging between 300000 D and 800000 D, said carragheenate having a calcium sulphate content such that the viscosity at 20 °C of an aqueous solution at 1 wt. % of said iota carragheenate is about 120 cps (0.12 Pa.s), and such that an aqueous solution at 2 wt. % of said carragheenate has a thixotropic gel structure.</p> |
