  • Patent number: 7319119
    Abstract: Oil-in-water emulsions which contain (i) 100 parts by weight of a polydimethylsiloxane (P) having aminoalkyl groups and having an amine number of at least 0.1 meq/g of polydimethylsiloxane (P), composed of units of the general formula I R1aR2bSiO(4?a?b/2),??(I) ?in which R2 are aminoalkyl radials of the formula II —R3—NR4R5,,??(II) (ii) protonating agent, (iii) water and (iv) not more than 5 parts by weight of emulsifier, are stable and provide for improved water repellency of porous and nonporous, absorptive and non-absorptive substrates treated therewith.
