Abstract
A gel type applicator stick of adhesive, deodorant or other dispersoid containing in percentages by weight from 0.01 to 45% dispersoid, 10 to 90% water or aqueous solvent and from 5 to 40% of a gel forming agent which is a reaction product of an automatic diisocyanate having 8 to 30 carbon atoms and a monoalkanolamine or dialkanolamine having 2 to 16 carbon atoms.
Claims18
A shaped gel applicator containing a water dispersible material to be applied to a surface by rubbing the gel over the surface which comprises
- a. 5% to 40% by weight of a gel which is the reaction product of an aromatic diisocyanate having 8 to 30 carbon atoms, the isocyanate groups of the diisocyanate being bonded directly to an aromatic ring, with a mono- alkanolamine or dialkanolamine having 2 to 16 carbon atoms;
- b. 10% to 90% by weight of water or a water and water miscible organic solvent mixture;
- and
- c. 0.01% to 45% by weight of said material to be applied to the surface. all percentages by weight being calculated on the sum of the three aforementioned components.
A stick-type gel applicator adapted for coating a surface with a dispersoid by rubbing a gel over a surface comprising
- a. from about 0.01 to 45% of the dispersoid dispersed in
- b. from about 5 to 40% of a gel which comprises the reaction product of a diisocyanate having a isocyanato groups attached directly to an aromatic ring containing from 8 to 30 carbon atoms and a mono-alkanolamine or dialkanolamine having from 2 to 16 carbon atoms, and
- c. from about 10 to 90% by weight water or a water-organic solvent mixture.
